NavDeepLinkBuilder

Kotlin |Java

class NavDeepLinkBuilder

kotlin.Any
↳	androidx.navigation.NavDeepLinkBuilder

Class used to construct deep links to a particular destination in a NavGraph.

When this deep link is triggered:

1. The task is cleared.
2. The destination and all of its parents will be on the back stack.
3. Calling NavController#navigateUp() will navigate to the parent of the destination.

The parent of the destination is the start destination of the containing navigation graph. In the cases where the destination is the start destination of its containing navigation graph, the start destination of its grandparent is used.

You can construct an instance directly with NavDeepLinkBuilder(Context) or build one using an existing NavController via NavController#createDeepLink().

Summary

Public constructors
<init>(@NonNull context: Context) Construct a new NavDeepLinkBuilder.

Public methods
PendingIntent	createPendingIntent() Construct a PendingIntent to the deep link destination.
TaskStackBuilder	createTaskStackBuilder() Construct the full task stack needed to deep link to the given destination.
NavDeepLinkBuilder	setArguments(@Nullable args: Bundle?) Set optional arguments to send onto the destination
NavDeepLinkBuilder	setComponentName(@NonNull activityClass: Class<out Activity!>) Sets an explicit Activity to be started by the deep link created by this class.
NavDeepLinkBuilder	setComponentName(@NonNull componentName: ComponentName) Sets an explicit Activity to be started by the deep link created by this class.
NavDeepLinkBuilder	setDestination(@IdRes destId: Int) Sets the destination id to deep link to.
NavDeepLinkBuilder	setGraph(@NavigationRes navGraphId: Int) Sets the graph that contains the deep link destination.
NavDeepLinkBuilder	setGraph(@NonNull navGraph: NavGraph) Sets the graph that contains the deep link destination.

Public constructors

<init>

NavDeepLinkBuilder(@NonNull context: Context)

Construct a new NavDeepLinkBuilder. If the context passed in here is not an Activity, this method will use android.content.pm.PackageManager#getLaunchIntentForPackage(String) as the default activity to launch, if available.

Parameters
context	Context: Context used to create deep links

Public methods

createPendingIntent

@NonNull fun createPendingIntent(): PendingIntent

Construct a PendingIntent to the deep link destination.

This constructs the entire task stack needed.

You must have set a NavGraph and set a destination before calling this method.

Return
PendingIntent: a PendingIntent constructed with TaskStackBuilder#getPendingIntent(int, int) to deep link to the given destination

createTaskStackBuilder

@NonNull fun createTaskStackBuilder(): TaskStackBuilder

Construct the full task stack needed to deep link to the given destination.

You must have set a NavGraph and set a destination before calling this method.

Return
TaskStackBuilder: a TaskStackBuilder which can be used to send the deep link or create a PendingIntent to deep link to the given destination.

setArguments

@NonNull fun setArguments(@Nullable args: Bundle?): NavDeepLinkBuilder

Set optional arguments to send onto the destination

Parameters
args	Bundle?: arguments to pass to the destination

Return
NavDeepLinkBuilder: this object for chaining

setComponentName

@NonNull fun setComponentName(@NonNull activityClass: Class<out Activity!>): NavDeepLinkBuilder

Sets an explicit Activity to be started by the deep link created by this class.

Parameters
activityClass	Class<out Activity!>: The Activity to start. This Activity should have a NavController which uses the same NavGraph used to construct this deep link.

Return
NavDeepLinkBuilder: this object for chaining

setComponentName

@NonNull fun setComponentName(@NonNull componentName: ComponentName): NavDeepLinkBuilder

Sets an explicit Activity to be started by the deep link created by this class.

Parameters
componentName	ComponentName: The Activity to start. This Activity should have a NavController which uses the same NavGraph used to construct this deep link.

Return
NavDeepLinkBuilder: this object for chaining

setDestination

@NonNull fun setDestination(@IdRes destId: Int): NavDeepLinkBuilder

Sets the destination id to deep link to.

Parameters
destId	Int: destination ID to deep link to.

Return
NavDeepLinkBuilder: this object for chaining

setGraph

@NonNull fun setGraph(@NavigationRes navGraphId: Int): NavDeepLinkBuilder

Sets the graph that contains the deep link destination.

Parameters
navGraphId	Int: ID of the NavGraph containing the deep link destination

Return
NavDeepLinkBuilder: this object for chaining

setGraph

@NonNull fun setGraph(@NonNull navGraph: NavGraph): NavDeepLinkBuilder

Sets the graph that contains the deep link destination.

If you do not have access to a NavController, you can create a NavigatorProvider and use that to programmatically construct a navigation graph or use NavInflater.

Parameters
navGraph	NavGraph: The NavGraph containing the deep link destination

Return
NavDeepLinkBuilder: this object for chaining
