Объявление зависимостей

Чтобы добавить зависимость от Navigation, необходимо добавить репозиторий Google Maven в свой проект. Подробнее см. в репозитории Google Maven .

Добавьте зависимости для необходимых артефактов в файл build.gradle вашего приложения или модуля:

классный 

plugins {
  // Kotlin serialization plugin for type safe routes and navigation arguments
  id 'org.jetbrains.kotlin.plugin.serialization' version '2.0.21'
}
  
dependencies {
  def nav_version = "2.9.6"

  // Jetpack Compose Integration
  implementation "androidx.navigation:navigation-compose:$nav_version"

  // Views/Fragments Integration
  implementation "androidx.navigation:navigation-fragment:$nav_version"
  implementation "androidx.navigation:navigation-ui:$nav_version"

  // Feature module support for Fragments
  implementation "androidx.navigation:navigation-dynamic-features-fragment:$nav_version"

  // Testing Navigation
  androidTestImplementation "androidx.navigation:navigation-testing:$nav_version"

  // JSON serialization library, works with the Kotlin serialization plugin.
  implementation "org.jetbrains.kotlinx:kotlinx-serialization-json:1.7.3"
}

Котлин 

plugins {
  // Kotlin serialization plugin for type safe routes and navigation arguments
  kotlin("plugin.serialization") version "2.0.21"
}

dependencies {
  val nav_version = "2.9.6"

  // Jetpack Compose integration
  implementation("androidx.navigation:navigation-compose:$nav_version")

  // Views/Fragments integration
  implementation("androidx.navigation:navigation-fragment:$nav_version")
  implementation("androidx.navigation:navigation-ui:$nav_version")

  // Feature module support for Fragments
  implementation("androidx.navigation:navigation-dynamic-features-fragment:$nav_version")

  // Testing Navigation
  androidTestImplementation("androidx.navigation:navigation-testing:$nav_version")

  // JSON serialization library, works with the Kotlin serialization plugin
  implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.7.3")
}

Безопасные аргументы

Чтобы добавить Safe Args в свой проект, включите следующий classpath в файл build.gradle верхнего уровня:

классный 

buildscript {
    repositories {
        google()
    }
    dependencies {
        def nav_version = "2.9.6"
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version"
    }
}

Котлин 

buildscript {
    repositories {
        google()
    }
    dependencies {
        val nav_version = "2.9.6"
        classpath("androidx.navigation:navigation-safe-args-gradle-plugin:$nav_version")
    }
}

Вам также необходимо применить один из двух доступных плагинов.

Чтобы сгенерировать код языка Java, подходящий для Java или смешанных модулей Java и Kotlin, добавьте эту строку в файл build.gradle вашего приложения или модуля :

классный 

plugins {
  id 'androidx.navigation.safeargs'
}

Котлин 

plugins {
    id("androidx.navigation.safeargs")
}

В качестве альтернативы, чтобы сгенерировать код Kotlin, подходящий для модулей только Kotlin, добавьте:

классный 

plugins {
  id 'androidx.navigation.safeargs.kotlin'
}

Котлин 

plugins {
    id("androidx.navigation.safeargs.kotlin")
}

У вас должно быть android.useAndroidX=true в файле gradle.properties в соответствии с переходом на AndroidX .

  • Переход по глубинной ссылке на NavDestination теперь возможен только через глубинную ссылку, явно добавленную к пункту назначения. Это также означает, что переход по маршруту к пункту назначения возможен только с помощью перегрузки функции Navigation, принимающей строковый маршрут. Это устраняет уязвимость, позволявшую создавать глубинную ссылку на потенциально защищённый пункт назначения. ( Ie30e6 )

Обновление зависимостей

  • Navigation Safe Args теперь зависит от Kotlin 1.9.24, а не от Kotlin 2.X, что гарантирует отсутствие необходимости обновления для разработчиков. ( a4129a )
  • Навигация Compose теперь зависит от Compose 1.7.2 .

Версия 2.8.0

4 сентября 2024 г.

Выпущена версия androidx.navigation:navigation-*:2.8.0 . Версия 2.8.0 содержит следующие изменения .

Важные изменения по сравнению с версией 2.7.0

Навигация Kotlin DSL Type-Safety

  • Навигация теперь обеспечивает типобезопасность для Kotlin DSL (используемого Navigation Compose) с помощью сериализации Kotlin, что позволяет вам определять пункты назначения в вашем навигационном графе с помощью типобезопасных объектов и классов данных: 
    // Define a home destination that doesn't take any arguments
    @Serializable
    object Home

    // Define a profile destination that takes an ID
    @Serializable
    data class Profile(val id: String)

    // Now define your NavHost using type safe objects
    NavHost(navController, startDestination = Home) {
        composable<Home> {
            HomeScreen(onNavigateToProfile = { id ->
                navController.navigate(Profile(id))
            })
        }
        composable<Profile> { backStackEntry ->
            val profile: Profile = backStackEntry.toRoute()
            ProfileScreen(profile)
        }
    }

Дополнительную информацию см . в записи блога Navigation Compose meet Type Safety .

Навигация Составление Предиктивный Назад

  • Navigation Compose теперь поддерживает предиктивный возврат в приложении через новые API SeekableTransitionState из compose-animation. Это позволяет использовать жест «Назад» для просмотра предыдущего пункта назначения с вашим пользовательским переходом, прежде чем принять решение о подтверждении транзакции жестом завершения или об отмене.

Навигационный фрагмент компонуется

  • Добавлен новый артефакт navigation-fragment-compose , включающий альтернативу NavHostFragment — ComposableNavHostFragment , позволяющий добавлять компонуемые пункты назначения в XML-файлы навигации. Каждый composable пункт назначения должен быть выражен как метод верхнего уровня @Composable без аргументов, полное имя которого используется в качестве атрибута android:name для каждого пункта назначения. При переходе к одному из этих пунктов назначения создается содержащий его фрагмент для отображения компонуемого содержимого. 
  // In HomeScreen.kt
  @Composable
  fun HomeScreen() {
    // Your Composable content here
  }

  // In your navigation.xml
  <composable
    android:id="@+id/home_screen"
    android:name="com.example.HomeScreenKt\$HomeScreen" />

Другие изменения

  • Навигация Compose теперь зависит от Compose 1.7.0.
  • Навигация теперь предоставляет новый класс CollectionNavType<T> , подкласс NavType<T> для аргументов, основанных на коллекциях, таких как списки, массивы и карты. Все массивы NavType по умолчанию ( IntArrayType , LongArrayType , FloatArrayType , BoolArrayType и StringArrayType ) теперь наследуются от этого нового класса.
  • NavType теперь имеет встроенную поддержку списков Int, String, Boolean, Float и Long.

Исправления ошибок

  • При навигации к дублирующимся или общим пунктам назначения навигация будет отдавать приоритет переходу к ближайшему совпадающему пункту назначения от текущего местоположения на графике. ( Ic89a4 , b/352006850 )
  • Навигация в безопасных аргументах теперь дополнена новым NavType.EnumType . Это означает, что для типов Enum больше не требуются пользовательские NavType . Обратите внимание, что SerialName для Enum должно быть полным именем по умолчанию. ( I66d22 , b/346475493 )
  • Навигация по безопасным аргументам добавила встроенную поддержку для типов аргументов, допускающих значение NULL, включая Int? , Long? , Float? , Boolean? и Enum<*>? . ( I32d13 , I1c580 , Ifba66 , I978b0 , Ide076 , b/351994237 )

  • Улучшить сообщение об ошибке для пользовательских сериализаторов, объявленных непосредственно в полях класса через @Serializable(with =...) чтобы уточнить, что в настоящее время эта функция не поддерживается. ( I052b0 , b/341319151 )
  • Тестовый API SavedStateHandleFactory теперь можно использовать в тестах, не связанных с Android, но для этого потребуется, чтобы Robolectric поддерживал анализ аргументов с помощью Bundles. ( I76cdc , b/340966212 )
  • Исправлен сбой, связанный с восстановлением состояния при возобновлении работы приложения после завершения процесса с использованием типобезопасной навигации в Compose. ( Ia8f38 , b/341801005 )
  • Исправлена ​​ошибка в Navigation Compose, из-за которой после отмены предиктивного жеста «Назад» элемент NavBackStackEntry , к которому пользователь возвращается, никогда не возвращается в состояние жизненного цикла RESUMED . Это также обеспечивает корректную анимацию возврата к пункту назначения, а не его закрепление после броска. ( I97a0c , b/346608857 )
  • При использовании предиктивного возврата с Navigation Compose выталкиваемый пункт назначения теперь будет иметь правильный z-порядок, корректно анимируясь поверх входящего пункта назначения. ( I2077b , b/345993681 )

  • Исправлены проблемы восстановления состояния стека переходов навигации, возникавшие при попытке восстановить запись стека переходов, недоступную по идентификатору из текущего пункта назначения. Поскольку маршруты поддерживаются идентификаторами, пункты назначения, созданные с использованием маршрутов, также были затронуты. Это также устраняет сбой, вызванный вызовом clearBackStack() , имевшим ту же основную проблему. ( I423c3 , b/339908057 )

  • Greatly improved the performance (both in terms of time and number of allocations) of comparing two graphs. This means that calls such as setGraph which internally compare the new graph to the existing one are much faster and result in fewer skipped frames. Thank you Michał Z for the thorough analysis that led to this improvement. ( I6ad62 )
  • NavHost will now render the start destination on the first composition pass instead of needing to wait for the second pass to read updated state. ( I439a7 , b/304852206 )

Исправления ошибок

  • Fixed an issue where your back stack would be popped if you called setGraph more than once with the exact same graph only if there was a destination in your graph that contained an action linking two destinations. ( Ieaed7 )
  • Dialogs that were navigated to and dismissed in quick succession will no longer leak into the list of NavController.visibleEntries . ( I67586 , b/287969970 )
  • When an entry is popped followed by a configuration change, the entry's ViewModel will now be cleared properly if saveState is false. ( Idf242 , b/298164648 )
  • Fixed an issue where NavController could handle the same deep link more than once if the back stack was entirely empty before a configuration change or call to setGraph only when the incoming Intent had the FLAG_ACTIVITY_NEW_TASK flag set. ( I73c7f )

Animations from Accompanist

Now that AnimatedContent is stable, we were able to move the code from Accompanist Navigation Animation back into Navigation Compose itself.

This means all of the support for setting custom transitions that existed in AnimatedNavHost is directly supported in NavHost .

No additional changes will be made to Accompanist Navigation Animation and we'll be formally deprecating it soon, along with guidance on how to migrate back to Navigation Compose itself, but it'll be the inverse of the migration guide with no other API changes required if you're already using the latest Accompanist alpha ( 0.31.2-alpha ).

Animations from Accompanist

Now that AnimatedContent is stable, we were able to move the code from Accompanist Navigation Animation back into Navigation Compose itself.

This means all of the support for setting custom transitions that existed in AnimatedNavHost is directly supported in NavHost .

No additional changes will be made to Accompanist Navigation Animation and we'll be formally deprecating it soon, along with guidance on how to migrate back to Navigation Compose itself, but it'll be the inverse of the migration guide with no other API changes required if you're already using the latest Accompanist alpha ( 0.31.2-alpha ). ( b/197140101 )

Исправления ошибок

  • From Navigation 2.6.0-rc02 : Fixed an issue with Navigation in Fragments where navigating with popUpTo and popping a fragment off the back stack without recreating its view would cause system back to stop working. ( Ieb8d4 , b/281726455 )

Обновления зависимостей

  • Navigation now depends on Compose 1.5.0-beta01 .

Версия 2.6.0

Версия 2.6.0

7 июня 2023 г.

androidx.navigation:navigation-*:2.6.0 is released. Version 2.6.0 contains these commits.

Important changes to Navigation since 2.5.0

  • NavBackStackEntry 's arguments and the arguments passed to an OnDestinationChangedListener are now only a copy of the immutable arguments that were created when you navigated to the destination. This means any changes made to those Bundles will not be reflected in subsequent accesses to the arguments or other OnDestinationChangedListener instances.
  • NavDeepLink now supports default values for arrays, which allows support for repeated query params that will map to the argument's array type. NavType also now includes a default method which can be overridden to combine two parsed values.
  • Custom subclasses of NavType can now override serializeAsValue to serialize a value into a String, allowing both serialization and deserialization (via parseValue ) to be entirely encapsulated in the NavType class. StringType now overrides this method to call Uri.encode on the given String .

Important changes to Navigation Compose since 2.5.0

  • When previewing a composable with NavHost , it will now show the NavGraph's startDestination by default.
  • NavController.popBackStack(route) , NavController.getBackStackEntry(route) , NavController.clearBackStack(route) now all support routes with arguments partially or fully filled in. Note that the arguments have to be an exact match with the entry's arguments.
  • Attempting to create an empty NavDeepLink using the navDeepLink Kotlin DSL will now result in a lint warning indicating that a deep link needs an uri, action, and/or mimetype to be valid.

Important changes to Navigation with Fragments since 2.5.0

  • NavHostFragment no longer intercepts the system back button itself. This allows the underlying FragmentManager to handle system back. This allows Fragment 1.7.0-alpha01 and higher to provide an In-App Predictive Back animation on Android U devices.
  • When using Navigation with Fragments, attempting to manually do a FragmentTransaction that adds a fragment to the FragmentManager 's back stack will now throw an IllegalArgumentException . You should always add fragments via the navigate() API.
  • When using the exact string ${applicationId} as the placeholder in the app:data and app:dataPattern attributes in the activity element of a navigation XML file, the placeholder will be automatically filled in with the packageName of the context upon inflation.
  • The FragmentNavigator now uses the transition APIs when navigating and popping NavBackStackEntries . This means that the NavBackStackEntry Lifecycle will now wait for the entering and exiting fragment special effects to complete before moving their final Lifecycle.State .
  • The DialogFragmentNavigator now uses the transition APIs when navigating and popping NavBackStackEntries . This means that the NavBackStackEntry Lifecycle will now wait for the DialogFragment Lifecycle to move to DESTROYED before moving to DESTROYED itself.
  • NavHostFragment now allows you to retrieve the NavController as soon as the NavHostFragment is attached to the FragmentManager , rather than only after onCreate() .
  • Navigation's support for Dynamic Feature Modules now depend on the granular Play Feature Delivery Library.
  • Navigation Safe Args now depends on Android Gradle Plugin version 7.3.0. This means it is now only compatible with versions 7.3.0+.

Important changes to NavigationUI since 2.5.0

  • When passing the ID of a navigation graph to AppBarConfiguration (such as via a Menu ), NavigationUI now only considers the start destination of that navigation graph as a top level destination, rather than incorrectly marking every destination within the graph as a top level destination. The behavior of passing the ID of an individual destination is unchanged. This same functionality is available to your own code via the new isTopLevelDestination function on AppBarConfiguration .
  • The setupWithNavController integrations in NavigationUI for working with the top app bar will now parse R.string values for ReferenceType arguments found in your android:label into their String values instead of outputting the auto-generated resource integer.
  • NavigationUI now provides logs when it fails to navigate via a selected MenuItem .

Исправления ошибок

  • Fixed checks for invalid route such that if a NavDestination contains non-nullable NavArgument , this destination's route must contain placeholders for args named the same as the non-nullable NavArgument . ( Ic62bf , b/274697949 )
  • Deeplink navigations based on Action/MimeType will now fail if the navigation operation is missing a non-nullable NavArgument required by the NavDestination that the Action/MimeType matches with. ( Ibfa17 , b/271777424 )
  • When NavController sets a graph with the same route and destinations as the previous graph, it now properly replaces its current graph nodes and its back stack destinations with new instances. This fixes a crash when using onLaunchSingleTop without saving state in Navigation Compose. This also fixes an error where navigating to destinations associated with the root graph builds and incorrect back stack. ( I5bc58 , b/275258161 , b/275407804 )

  • FragmentNavigator will now properly pop entries when the back stack is popped via system back or popBackStack() and whether or not the transaction uses effects for the fragment. ( I81bdf )
  • Adding fragments to the FragmentNavigator 's FragmentManager without using navigation will no longer cause a crash. ( b17204 , b/274167493 )

Important changes since 2.3.0

  • All Navigation artifacts have been rewritten in Kotlin. This has improved the nullability of classes using generics (such as NavType subclasses). All Kotlin extension functions that used to be part of the -ktx artifacts have been moved to their respective main artifacts. The -ktx artifacts will continue to be published, but are completely empty.
  • The navigation-fragment artifact now contains a prebuilt implementation of a two pane layout via the new AbstractListDetailFragment . This fragment uses a SlidingPaneLayout to manage a list pane (which your subclass provides) and a detail pane, which uses a NavHostFragment as its implementation, as seen in our example implementation .
  • The currentBackStackEntryAsFlow() method on NavController provides a Flow that emits whenever the current NavBackStackEntry changes. This flow can be used as an alternative to manually managing an OnDestinationChangedListener .
  • NavController now offers the ability to retrieve a list of all visible NavBackStackEntry instances as a StateFlow via the experimental visibleEntries property.
  • It is now possible to extend the NavType class to create custom NavTypes. Custom types are supported only when building your navigation graph programmatically, such as via the Navigation Graph Kotlin DSL .

  • Navigation now provides findStartDestination() and getHierarchy() APIs that can be used to help implement custom NavigationUI. findStartDestination() is an extension function on NavGraph that will locate the actual start destination that will be displayed when you navigate to the graph, even if the startDestination is itself a nested NavGraph . getHierarchy() is a function on NavDestination that can be used to verify if a given destination is within the hierarchy of another.

    val matchingRoute: Boolean = destination.hierarchy.any { it.route == routeToFind }

  • NavigationUI methods that took a BottomNavigationView have been updated to instead take its superclass introduced in Material 1.4.0 , NavigationBarView . This allows these methods to be used with the NavigationRailView .

  • When inflating an <action> element via XML, animation attributes can use attributes pulled from your theme using the app:enterAnim="?attr/transitionEnter" syntax.

  • Safe Args now generates a fromSavedStateHandle() method for each NavArgs class. ( #122 , b/136967621 )

    class HomeViewModel(savedStateHandle: SavedStateHandle) : ViewModel() {
  // Create a HomeDestinationArgs class with type safe accessors for each argument
  // defined on your destination
  private val args = HomeDestinationArgs.fromSavedStateHandle(savedStateHandle)
}

Navigation Routes and the Kotlin DSL

Previous versions of Navigation relied on each destination having a constant integer ID that would uniquely identify it from its sibling destinations and allow you to navigate() to that destination either directly or via an action. While this continues to be valid and useful, particularly in cases where you are defining your navigation graph in XML and can use auto-generated R.id constants or Safe Args (which uses those constants to generate code at build time), this system of unique integers did not capture the semantic meaning and expressiveness needed to support fully dynamic graphs built programmatically at runtime via the Navigation Kotlin DSL .

This release introduces a new option for uniquely identifying a destination in a navigation graph by its route . A route is a String that defines the unique path to a destination. All Kotlin DSL methods that took a destination ID are now deprecated and replaced with an equivalent API that takes a route.

Each route should be treated as the 'path' part of a Uri that defines that destination, eg, home , profile/{userId} , profile/{userId}/friends , etc. When the identity of a destination is associated with a specific piece of content, those dynamic arguments should be part of the route, following the same rules as implicit deep links .

All NavController APIs that used to only take an ID now have an overload that takes a route String . This includes navigate() , popBackStack() , popUpTo() , and getBackStackEntry() .

This has had some API implications:

  • The popUpTo Kotlin property on the Kotlin DSL has been deprecated in favor of popUpToId .
  • The getStartDestination() API has been deprecated in favor of getStartDestinationId() .

Unlike when navigating by ID, navigating by route follows the same rules as implicit deep links in that you can directly navigate to any destination in any nested graph, ensuring that these routes are usable in multi-module projects without explicitly adding an externally visible deep link to each destination.

Navigation Compose

The navigation-compose artifact provides integration between the Navigation Component and Jetpack Compose . It uses @Composable functions as the destinations in your application.

This release provides:

  • A NavHost composable that allows you to construct your navigation graph via a Kotlin DSL, using composable and dialog destinations, plus support for optional Navigators such as those from Accompanist Navigation Material .
  • Mandatory support for crossfading between destinations. Accompanist Navigation Animation can be used to control the enter and exit transitions using experimental Compose APIs.
  • Scoping of a Lifecycle to each composable destination. Each destination only reaches the RESUMED state when any entering transitions finish and immediately drops to STARTED when any exiting transitions start, thus allowing you to avoid all IllegalStateException and multi-touch issues by only triggering a navigate call when the Lifecycle is RESUMED .
  • Scoping of ViewModel (via the viewModel() API of Lifecycle ViewModel Compose 2.4.0 or hiltViewModel() of Hilt Navigation Compose 1.0.0 at the destination level, providing a scope that survives configuration changes and being on the back stack (when your Composable content is otherwise disposed) and a signal in the ViewModel's onCleared() that indicates the permanent disposal and cleaning up of state associated with that NavBackStackEntry .
  • Scoping of rememberSaveable state at a destination level, ensuring that all composable state is saved and restored automatically when you return to a destination.
  • Full support for saving and restoring the state of the NavController and its destination's state after process death and recreation.
  • Automatic integration with the system back button.

  • Support for passing arguments, attaching deep links to destinations, and returning a result to previous destinations.

  • Compose specific helpers in rememberNavController() and currentBackStackEntryAsState() to allow hoisting state and connecting the NavController to composables outside of the NavHost (such as a bottom navigation bar). 

val navController = rememberNavController()
Scaffold { innerPadding ->
    NavHost(navController, "home", Modifier.padding(innerPadding)) {
        composable("home") {
            // This content fills the area provided to the NavHost
            HomeScreen()
        }
        dialog("detail_dialog") {
            // This content will be automatically added to a Dialog() composable
            // and appear above the HomeScreen or other composable destinations
            DetailDialogContent()
        }
    }
}

See the Compose Navigation guide for more information.

Multiple back stacks

The NavController is responsible for managing the back stack of destinations, adding destinations to the back stack when you navigate() to them and removing them when you call popBackStack() or trigger the system back button. The existing NavOptions class and the integration into <action> elements in the navigation graph XML has been expanded to support saving and restoring the back stack.

As part of this change, the NavigationUI methods of onNavDestinationSelected() , BottomNavigationView.setupWithNavController() and NavigationView.setupWithNavController() now automatically save and restore the state of popped destinations, enabling support for multiple back stacks without any code changes. When using Navigation with Fragments, this is the recommended way to integrate with multiple back stacks.

The underlying APIs for saving and restoring the state are exposed via a number of surfaces:

  • In Navigation XML, the <action> element can now use the boolean attributes of app:popUpToSaveState and app:restoreState to save the state of any destinations popped via app:popUpTo and restore the state associated with the destination passed as the app:destination :

    <action
  android:id=”@+id/swap_stack”
  app:destination=”@id/second_stack”
  app:restoreState=”true”
  app:popUpTo=”@id/first_stack_start_destination”
  app:popUpToSaveState=”true” />

  • In the navOptions Kotlin DSL , you can add the restoreState boolean property and the saveState boolean property on the popUpTo builder : 

    // Use the navigate() method that takes a navOptions DSL Builder
navController.navigate(selectedBottomNavRoute) {
  launchSingleTop = true
  restoreState = true
  popUpTo(navController.graph.findStartDestination().id) {
    saveState = true
  }
}

  • In manually building a NavOptions object via the NavOptions.Builder , you can use the setRestoreState() and new overload to setPopUpTo() that takes an additional saveState parameter. 

    NavOptions navOptions = new NavOptions.Builder()
  .setLaunchSingleTop(true)
  .setRestoreState(true)
  .setPopUpTo(NavGraph.findStartDestination(navController.getGraph()).getId(),
    false, // inclusive
    true) // saveState
  .build();
navController.navigate(selectedBottomNavId, null, navOptions);

  • Programmatic calls to popBackStack() can now include an additional saveState parameter.

  • You can use the clearBackStack() method to clear any state that was saved with popBackStack() or popUpToSaveState .

In all cases, the NavController will save and restore the state of each NavBackStackEntry , including any navigation destination scoped ViewModel instances. The Navigator APIs have been updated to enable each Navigator to support saving and restoring their own state.

Изменения поведения

  • NavDeepLinkBuilder now adds PendingIntent.FLAG_IMMUTABLE to the PendingIntent returned by createPendingIntent() , ensuring that this API works as expected when targeting Android 12.
  • Navigation now depends on Lifecycle 2.3.1 and now marks setGraph() , popBackStack() , navigateUp() , and navigate() , the methods that update the NavBackStackEntry Lifecycle , as @MainThread , aligning Navigation with the main thread enforcement introduced in Lifecycle 2.3.0 .
  • Deep links now verify that all required arguments (those without default values) are present in the Uri .
  • NavDeepLink parsed arguments now consider pound signs in the same way as question marks as a separator between path segments, preventing an argument from spanning across the pound sign.
  • When generating actions, Kotlin code generated from Safe Args now puts arguments without default values before those with default values as parameters.
  • When generating arguments, Safe Args now puts parameters without default values before those with default values.
  • Safe-Args now depends on Android Gradle Plugin 4.2.0. This means you should no longer get the using applicationIdTextResource warning.

Known issues

  • Fixed in Navigation 2.5.0-alpha01 : accessing a ViewModel created via by navGraphViewModels() from a Fragment's onCreate() will fail with an IllegalStateException . ( b/213504272 )
  • Fixed in Navigation 2.5.0-alpha01 : Safe Args 2.4.0 is incompatible with Android Gradle Plugin 7.1.0 and higher. ( b/213086135 )
  • Deep linking with multiple nested nav graphs doesn't correctly create the full backstack. ( b/214383060 )

androidx.navigation:navigation-*:2.4.0-beta02 is released. Version 2.4.0-beta02 contains these commits.

Изменения API

  • The handling of both explicit and implicit deep links now automatically adds the saveState flag when navigating to another graph, ensuring that code such as NavigationUI.setupWithNavController and code using multiple back stacks works as expected. ( Ic8807 )

Изменения поведения

  • Deep link patterns are now compiled lazily in NavDeepLink instead of during inflation. This should improve the inflation time of navigation graphs that include deep links. ( b8d257 , b/184149935 )

Исправления ошибок

  • Fixed an issue where NavBackStackEntries were being pushed down to Lifecycle.State.CREATED after moving to Lifecycle.State.STARTED when the NavHost is added directly to the activity's setContent() . ( Ia5ac1 , b/203536683 )
  • Fixed a race condition where popping a DialogFragment destination off of the back stack before the dialog was actually shown would not actually dismiss the dialog, resulting in a crash when the errant dialog was manually dismissed by the user. ( I687e5 )
  • Fixed an issue where the onNavDestinationSelected API on NavigationUI would return true even if you didn't actually navigate() to that navigation graph. It now uses the same logic used internally by setupWithNavController to only select the MenuItem associated with the current destination using the hierarchy of the destination. ( I2b053 )

  • Fixed an issue with AbstractListDetailFragment that caused the layout_width and layout_weight attributes on the list pane returned by onCreateListPaneView() to be incorrectly handled or ignored. ( f5fbf3 )
  • The visual state of dialog destinations now correctly stays in sync with the DialogFragmentNavigator 's state. This means that manually calling the asynchronous dismiss() API for DialogFragment now properly clears all dialog destinations above the now dismissed dialog. This does not affect cases where you use popUpTo or popBackStack() to dismiss your dialog. ( I77ba2 )
  • AbstractAppBarOnDestinationChangedListener now has clearer error messaging for onDestinationChanged() . ( Ie742d )

  • The navigation-fragment artifact now contains a prebuilt implementation of a two pane layout via the new AbstractListDetailFragment . This fragment uses a SlidingPaneLayout to manage a list pane (which your subclass provides) and a detail pane, which uses a NavHostFragment as its implementation, as seen in our example implementation . ( Iac4be , b/191276636 )
  • The NavHost of the navigation-compose artifact now supports dialog destinations in addition to composable destinations. These dialog destinations will each be shown within a Composable Dialog , floating above the current composable destination. ( I011d0 ) 
val navController = rememberNavController()
    Scaffold { innerPadding ->
        NavHost(navController, "home", Modifier.padding(innerPadding)) {

    }

Изменения API

  • The add function in NavigatorState has been renamed to push . All current calls to add() will need to be changed to push(). ( Ie89fc , b/172112072 )
  • Custom Navigator instances can now use the pushWithTransaction and popWithTransition APIs on NavigatorState to push or pop a destination asynchronously. Note that this APIs are not yet used by any of the included navigators. ( Ic4d7c , b/172112072 )

Изменения поведения

  • NavDeepLinkBuilder now adds PendingIntent.FLAG_IMMUTABLE to the PendingIntent returned by createPendingIntent() , ensuring that this API works as expected when targeting Android 12. ( If8c52 )

androidx.navigation:navigation-*:2.4.0-alpha02 is released. Version 2.4.0-alpha02 contains these commits.

Новые функции

  • Routes are now supported for Activity, Fragment and Dialog destinations, as well as throughout the DynamicNavigation Kotlin DSL. ( Ib5544 , Ia617b , I22f96 , b/188914648 , b/188901565 )
  • NavigationUI has temporarily added experimental APIs to allow opting out of saving your state. While always saving the state is the correct behavior, there are still uses of deprecated libraries (ie retained fragments), that cannot be supported when saving the state so this gives an opportunity for apps to slowly convert away from any unsupported APIs. ( Idf93c )

  • Navigation now provides findDestination() and getHierarchy() APIs that can be used to help implement custom NavigationUI. findDestination() is an extension function on NavGraph that will locate a destination within the graph. getHierarchy() is a function on NavDestination that can be used to verify if a given destination is within the hierarchy of another.( I2932f , b/188183365 ) 

    val matchingRoute: Boolean = destination.hierarchy.any { it.route == routeToFind }

  • NavigationUI methods that took a BottomNavigationView have been updated to instead take its superclass introduced in Material 1.4.0 , NavigationBarView . This allows these methods to be used with the NavigationRailView . ( Ib0b36 , b/182938895 )

  • When inflating an <action> element via XML, animation attributes can use attributes pulled from your theme using the app:enterAnim="?attr/transitionEnter" syntax. ( I07bc1 , b/178291654 )

Изменения API

  • DialogFragmentNavigator now uses the NavigatorState.pop() API to inform the NavController when a dialog is dismissed by hitting the system back button or clicking outside of it, ensuring that the NavController state is always in sync with the Navigator's state. ( I2ead9 )

  • Navigation no longer gives a ConcurrentModificationException when using manipulating the list of OnDestinationChangedListeners from with an onDestinationChanged callback. ( Ib1707 , b/188860458 )

  • Safe Args no longer crashes when attempting to generate direction properties in Kotlin. ( Id2416 , b/188564435 )

  • The setId method on NavDestination is now properly annotated with @IdRes , so it only accepts resource ids. ( I69b80 )

Version 2.4.0-alpha01

18 мая 2021 г.

androidx.navigation:navigation-*:2.4.0-alpha01 is released. Version 2.4.0-alpha01 contains these commits.

Новые функции

  • The currentBackStackEntryAsFlow() method on NavController provides a Flow that emits whenever the current NavBackStackEntry changes. This flow can be used as an alternative to manually managing an OnDestinationChangedListener . ( I19c4a , #89 , b/163947280 )

Multiple back stacks

The NavController is responsible for managing the back stack of destinations, adding destinations to the back stack when you navigate() to them and removing them when you call popBackStack() or trigger the system back button. The existing NavOptions class and the integration into <action> entries in the navigation graph XML has been expanded to support saving and restoring the back stack. ( b/80029773 )

As part of this change, the NavigationUI methods of onNavDestinationSelected() , BottomNavigationView.setupWithNavController() and NavigationView.setupWithNavController() now automatically save and restore the state of popped destinations, enabling support for multiple back stacks without any code changes. When using Navigation with Fragments, this is the recommended way to integrate with multiple back stacks. ( Ie07ca )

The underlying APIs for saving and restoring the state are exposed via a number of surfaces:

  • In Navigation XML, the <action> element can now use the boolean attributes of app:popUpToSaveState and app:restoreState to save the state of any destinations popped via app:popUpTo and restore the state associated with the destination passed as the app:destination : 

    <action
  android:id=”@+id/swap_stack”
  app:destination=”@id/second_stack”
  app:restoreState=”true”
  app:popUpTo=”@id/first_stack_start_destination”
  app:popUpToSaveState=”true” />

  • In the navOptions Kotlin DSL , you can add the restoreState boolean property and the saveState boolean property on the popUpTo builder : 

    // Use the navigate() method that takes a navOptions DSL Builder
navController.navigate(selectedBottomNavRoute) {
  launchSingleTop = true
  restoreState = true
  popUpTo(navController.graph.startDestinationId) {
    saveState = true
  }
}

  • In manually building a NavOptions object via the NavOptions.Builder , you can use the setRestoreState() and new overload to setPopUpTo() that takes an additional saveState parameter. 

    NavOptions navOptions = new NavOptions.Builder()
  .setLaunchSingleTop(true)
  .setRestoreState(true)
  .setPopUpTo(navController.getGraph().getStartDestinationId(),
    false, // inclusive
    true) // saveState
  .build();
navController.navigate(selectedBottomNavId, null, navOptions);

  • Programmatic calls to popBackStack() can now include an additional saveState parameter.

In all cases, the NavController will save and restore the state of each NavBackStackEntry , including any navigation destination scoped ViewModel instances. The Navigator APIs have been updated to enable each Navigator to support saving and restoring their own state.

The ComposeNavigator used for composable destinations in Navigation Compose and the FragmentNavigator and DynamicFragmentNavigator used for <fragment> destinations in Navigation with Fragments have both been updated to use the new Navigator APIs and support saving and restoring state.

Navigation Routes

A route is a String that uniquely identifies a destination. While previously only used in Navigation Compose , this concept has now graduated to become a part of the core Navigation APIs. This provides an alternative to using integer IDs when constructing your graph through the Navigation Kotlin DSL . ( b/172823546 )

All APIs that used to only take an ID now have an overload that takes a route String . This includes navigate() , popBackStack() , popUpTo() , and getBackStackEntry() .

This has had some API implications:

  • The popUpTo kotlin property on the Kotlin DSL has been deprecated in favor of popUpToId . ( I59c73 , b/172823546 )
  • The getStartDestination() API has been deprecated in favor of getStartDestinationId() . ( I0887f , b/172823546 )

For developers upgrading from previous versions of Navigation Compose to Navigation Compose 2.4.0-alpha01 , this means that the following imports on extension methods are no longer necessary and should be removed: 

import androidx.navigation.compose.navigation
import androidx.navigation.compose.createGraph
import androidx.navigation.compose.getBackStackEntry
import androidx.navigation.compose.navigate
import androidx.navigation.compose.popUpTo

The KEY_ROUTE argument has been replaced with the route property on NavDestination , allowing you to call navBackStackEntry.destination.route directly.

Изменения API

  • All Navigation artifacts have been rewritten in Kotlin. This has improved the nullability of classes using generics (such as NavType subclasses). All Kotlin extension functions that used to be part of the -ktx artifacts have been moved to their respective main artifacts. The -ktx artifacts will continue to be published, but are completely empty. ( b/184292145 )
  • NavDeepLinkBuilder now supports adding multiple distinct destinations to the generated back stack. ( I3ee0d , b/147913689 )
  • Add factory functions for DynamicNavHostFragment ( Icd515 , b/175222619 )
  • The unique ID of a NavBackStackEntry is now exposed as part of its public API. ( Ie033a )
  • The name and argument fields and destructuring functions of NamedNavArgument are now public. ( #174 , b/181320559 )
  • Introduced a new NavBackStackEntry#provideToCompositionLocals extension that provides the NavBackStackEntry to the relevant composition locals. ( #175 , b/187229439 )

Safe Args

  • Safe Args now generates a fromSavedStateHandle() method for each NavArgs class. ( #122 , b/136967621 ) 

    class HomeViewModel(savedStateHandle: SavedStateHandle) : ViewModel() {
  // Create a HomeDestinationArgs class with type safe accessors for each argument
  // defined on your destination
  private val args = HomeDestinationArgs.fromSavedStateHandle(savedStateHandle)
}

  • Updated Safe Args to depend on KotlinPoet 1.8.0 . ( #172 , b/183990444 )

Изменения поведения

  • Navigation now depends on Lifecycle 2.3.1 and now marks setGraph() , popBackStack() , navigateUp() , and navigate() , the methods that update the NavBackStackEntry Lifecycle , as @MainThread , aligning Navigation with the main thread enforcement introduced in Lifecycle 2.3.0 . ( b/171125856 )
  • Parsing Enum arguments from deep links is now case insensitive, allowing a deep link like http://www.example.com/red to match a www.example.com/{color} deep link even when the enum has the value of RED . ( #152 , b/135857840 )

Compose Compatibility

  • androidx.navigation:navigation-compose:2.4.0-alpha01 is only compatible with Compose version 1.0.0-beta07 and above.

Исправления ошибок

  • Fixed an issue where trailing argument placeholders would take precedence over deep links that have a matching exact suffix. ( #153 , b/184072811 )
  • NavHostFragment now supports custom Navigators that use the same @Navigator.Name("dialog") as the default DialogFragmentNavigator . ( Ib1c2c , b/175979140 )
  • Improved the behavior of NavigatorProvider#addNavigator to ensure that calling it repeatedly with the same instance does not cause issues. ( #176 , b/187443146 )

Новые функции

The navigation-compose artifact provides integration between the Navigation Component and Jetpack Compose . It uses @Composable functions as the destinations in your application.

This initial release provides:

  • A NavHost composable that allows you to construct your navigation graph via a Kotlin DSL.
  • Scoping of lifecycle, ViewModel , and remembered state at the destination level.
  • Automatic integration with the system back button.
  • Support for passing arguments, attaching deep links to destinations, and returning a result to previous destinations.
  • Compose specific helpers in rememberNavController() and currentBackStackEntryAsState() to allow hoisting state and connecting the NavController to composables outside of the NavHost (such as a bottom navigation bar).

See the Compose Navigation guide for more information.

Major changes since 2.2.0

  • Feature Module integration : The navigation-dynamic-features-runtime and navigation-dynamic-features-fragment artifacts allow you to navigate to destinations that are defined in feature modules, automatically handling the installation of the feature modules as needed. See Navigate with feature modules for more information.
  • Navigation Testing : The navigation-testing artifact provides a TestNavHostController that allows you to set the current destination and verify the back stack after navigation operations. See Test Navigation for more information.
  • Returning a Result : The NavBackStackEntry associated with each destination on the Navigation back stack now allows you to access a SavedStateHandle suitable for storing small amounts of saved state that should be associated with a particular back stack entry. See Returning a result to the previous Destination for more information.
  • NavigationUI support for Openable : All usages of DrawerLayout in NavigationUI have been replaced with the more generic Openable interface added in CustomView 1.1.0 and implemented by DrawerLayout in DrawerLayout 1.1.0 .
  • Action and Mime Type support in deep links : Deep linking has been expanded to support app:action and app:mimeType in addition to the app:uri previously available. NavController now supports navigating by any combination of these fields via the new NavDeepLinkRequest class. See Navigate using NavDeepLinkRequest for more information.

Известные проблемы

  • Support for deep link actions and mime types is not yet available in Manifest Merger . Until that work is completed, any generated <intent-filter> elements from the <nav-graph> element in your manifest won't include your mime type in its <data> element or your custom <action> . You must manually add an appropriate <intent-filter> to your manifest.

Версия 2.2.0

Версия 2.2.0

22 января 2020 г.

androidx.navigation:navigation-*:2.2.0 is released. Version 2.2.0 contains these commits .

Important changes since 2.1.0

  • NavBackStackEntry : You can now call NavController.getBackStackEntry() , passing in the ID of a destination or navigation graph on the back stack. The returned NavBackStackEntry provides a Navigation-driven LifecycleOwner , ViewModelStoreOwner (the same returned by NavController.getViewModelStoreOwner() ), and SavedStateRegistryOwner , in addition to providing the arguments used to start that destination.
  • Lifecycle ViewModel SavedState Integration : SavedStateViewModelFactory is now the default factory used when using by navGraphViewModels() or the ViewModelProvider constructor with a ViewModelStoreOwner returned by NavController.getBackStackEntry() or NavController.getViewModelStoreOwner() .
  • Query Parameter Support for Deep Links : Deep links with query parameters now support reordered query parameters; arguments that have a default value or are nullable are now optional when matching deep links.
  • Improved Animation Support : NavHostFragment now uses FragmentContainerView from Fragment 1.2.0 , fixing animation z-ordering issues and window insets dispatching to Fragments.

Версия 2.0.0

Версия 2.0.0

14 марта 2019 г.

Navigation 2.0.0 is released with no changes from 2.0.0-rc02 .

Version 2.0.0-rc02

6 марта 2019 г.

Navigation 2.0.0-rc02 provides new artifacts with the androidx.navigation group ID and changes its dependencies to the AndroidX equivalents.

The behavior of 2.0.0-rc02 is identical to behavior to Navigation 1.0.0-rc02 and no changes to your code should be required to update from 1.0.0-rc02 besides updating your dependencies to match the new dependencies .

Your project must have migrated to AndroidX to use 2.X releases of Navigation. Navigation 1.0 stable will be the last release using the Support Library dependencies; all future development beyond 1.0 will be based on AndroidX and build upon the 2.0 stable release.

Pre-AndroidX Dependencies

For the pre-AndroidX versions of Navigation, include these dependencies: 

dependencies {
    def nav_version = "1.0.0"

    implementation "android.arch.navigation:navigation-fragment:$nav_version" // For Kotlin use navigation-fragment-ktx
    implementation "android.arch.navigation:navigation-ui:$nav_version" // For Kotlin use navigation-ui-ktx
}

For Safe args , add the following classpath in your top level build.gradle file 

buildscript {
    repositories {
        google()
    }
    dependencies {
        classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0"
    }
}

Версия 1.0.0-beta01

4 февраля 2019 г.

This is the first beta release of Navigation; moving forward, the Navigation API is expected to stay stable until the next version unless there is a critical problem. This release contains some bug fixes and behavior changes.

Изменения поведения

  • Navigation now ensures that argument default values are treated identically at runtime and through Safe Args. As a consequence, only arguments with an app:argType="reference" can have a default value point to another resource (for example, @color/colorPrimary ). Attempting to use a reference default value with a different app:argType will result in an exception when parsing the navigation XML. b/123551990
  • Safe Args now depends on Android Gradle Plugin 3.3.0 aosp/888413
  • Safe Args now depends on Kotlin 1.3.20 aosp/888414

Исправления ошибок

  • Safe Args can now be used in library and feature modules on all versions of the Android Gradle Plugin. b/121304903
  • Fixed a regression that would cause a single popBackStack() operation to pop all copies of a destination off the top of the back stack, rather than just a single destination at a time. b/123552990
  • Fixed an issue where the FragmentNavigator state would desynchronize with the NavController 's state, causing an IllegalStateException when attempting to restore the back stack. b/123803044
  • Fixed an issue where the NavigationUI handled back arrow would not appear when using ProGuard with obfuscation. b/123449431
  • The code generated by Safe Args now properly handles using an app:argType pointing to a static inner class in the format .OuterClass$InnerClass . b/123736741
  • The Java code generated by Safe Args now properly handles global actions and deeply nested destinations. b/123347762

  • Safe Args now avoids duplicating identical classes for actions without arguments. The return type for no argument methods in generated NavDirections classes is now NavDirections . b/123233147
  • Safe Args generated Directions classes no longer have a public constructor - you should only be interacting with the generated static methods. b/123031660
  • Safe Args generated NavDirections classes no longer have a public constructor - they should only be generated via the static methods in the generated Directions classes. b/122963206
  • The returned Bundle from NavDirections ' getArguments() is now marked as @NonNull rather than @Nullable . b/123243957

Исправления ошибок

  • NavDeepLinkBuilder now correctly handles multiple simultaneous PendingIntent s to the same destination by using the arguments you pass in to determine the uniqueness. b/120042732
  • NavController now correctly handles popBackStack() operations when using a nested NavHostFragment or other child Fragments with a back stack. b/122770335

  • FragmentNavigator now throws a better error message if you attempt to do custom FragmentTransactions on the NavHostFragment 's FragmentManager . You should always use getChildFragmentManager() . b/112927148

Версия 1.0.0-альфа09

18 декабря 2018 г.

This release contains breaking API changes; please see the Breaking Changes section below.

We have chosen not to continue development of the android.arch.navigation:navigation-testing artifact. While it has proven helpful for internal testing of NavController , we strongly recommend alternate testing strategies, such as mocking the NavController instance in order to verify that the correct navigate() calls are being done. This approach is discussed in detail in the Single Activity talk at AndroidDevSummit 2018 and we'll be working on additional documentation specifically around testing with Navigation.
