Aparat i multimedia
Android 15 zawiera wiele funkcji, które poprawiają działanie aparatu i multimediów oraz zapewniają dostęp do narzędzi i sprzętu ułatwiających twórcom realizację ich wizji na urządzeniach z Androidem.
Więcej informacji o najnowszych funkcjach i rozwiązaniach dla deweloperów dotyczących multimediów i aparatów w Androidzie znajdziesz w prezencie Tworzenie nowoczesnych funkcji multimediów i aparatów w Androidzie z Google I/O.
Słabe oświetlenie
Android 15 introduces Low Light Boost, an auto-exposure mode available to both Camera 2 and the night mode camera extension. Low Light Boost adjusts the exposure of the Preview stream in low-light conditions. This is different from how the night mode camera extension creates still images, because night mode combines a burst of photos to create a single, enhanced image. While night mode works very well for creating a still image, it can't create a continuous stream of frames, but Low Light Boost can. Thus, Low Light Boost enables camera capabilities, such as:
- Providing an enhanced image preview, so users are better able to frame their low-light pictures
- Scanning QR codes in low light
If you enable Low Light Boost, it automatically turns on when there's a low light level, and turns off when there's more light.
Apps can record off the Preview stream in low-light conditions to save a brightened video.
For more information, see Low Light Boost.
Elementy sterujące kamerą w aplikacji
Android 15 adds an extension for more control over the camera hardware and its algorithms on supported devices:
- Advanced flash strength adjustments enabling precise control of flash
intensity in both
SINGLE
andTORCH
modes while capturing images.
Kontrola headroomu HDR
Android 15 会选择适合底层设备功能和面板位深的 HDR 余量。对于包含大量 SDR 内容的网页(例如显示单个 HDR 缩略图的消息应用),此行为最终可能会对 SDR 内容的感知亮度产生不利影响。在 Android 15 中,您可以使用 setDesiredHdrHeadroom
控制 HDR 余量,以便在 SDR 内容和 HDR 内容之间取得平衡。

Regulacja głośności
Android 15 introduces support for the CTA-2075 loudness standard to help you avoid audio loudness inconsistencies and ensure users don't have to constantly adjust volume when switching between content. The system leverages known characteristics of the output devices (headphones and speaker) along with loudness metadata available in AAC audio content to intelligently adjust the audio loudness and dynamic range compression levels.
To enable this feature, you need to ensure loudness metadata is available in
your AAC content and enable the platform feature in your app. For this, you
instantiate a LoudnessCodecController
object by
calling its create factory method with the audio
session ID from the associated AudioTrack
; this
automatically starts applying audio updates. You can pass an
OnLoudnessCodecUpdateListener
to modify or filter
loudness parameters before they are applied on the
MediaCodec
.
// Media contains metadata of type MPEG_4 OR MPEG_D
val mediaCodec = …
val audioTrack = AudioTrack.Builder()
.setSessionId(sessionId)
.build()
...
// Create new loudness controller that applies the parameters to the MediaCodec
try {
val lcController = LoudnessCodecController.create(mSessionId)
// Starts applying audio updates for each added MediaCodec
}
AndroidX media3 ExoPlayer will also be updated to use the
LoudnessCodecController
APIs for a seamless app integration.
Wirtualne urządzenia MIDI 2.0
Android 13 added support for connecting to MIDI 2.0 devices using USB, which communicate using Universal MIDI Packets (UMP). Android 15 extends UMP support to virtual MIDI apps, enabling composition apps to control synthesizer apps as a virtual MIDI 2.0 device just like they would with an USB MIDI 2.0 device.
wydajniejsze dekodowanie AV1 w oprogramowaniu;
dav1d, the popular AV1 software decoder from VideoLAN is available for Android devices that don't support AV1 decode in hardware. dav1d is up to 3x more performant than the legacy AV1 software decoder, enabling HD AV1 playback for more users, including some low and mid tier devices.
Your app needs to opt-in to using dav1d by invoking it by name
"c2.android.av1-dav1d.decoder"
. dav1d will be made the default AV1 software
decoder in a subsequent update. This support is standardized and backported to
Android 11 devices that receive Google Play system updates.
Narzędzia i produktywność programistów
Chociaż większość naszych działań na rzecz zwiększenia produktywności skupia się na takich narzędziach jak Android Studio, Jetpack Compose i biblioteki Jetpacka na Androida, zawsze szukamy sposobów na ułatwienie Ci realizacji Twoich pomysłów.
aktualizacje OpenJDK 17.
Android 15 continues the work of refreshing Android's core libraries to align with the features in the latest OpenJDK LTS releases.
The following key features and improvements are included:
- Quality-of-life improvements around NIO buffers
- Streams
- Additional
math
andstrictmath
methods util
package updates including sequencedcollection
,map
, andset
ByteBuffer
support inDeflater
- Security updates such as
X500PrivateCredential
and security key updates
These APIs are updated on over a billion devices running Android 12 (API level 31) and higher through Google Play System updates, so you can target the latest programming features.
Ulepszenia plików PDF
Android 15 includes substantial improvements to the PdfRenderer
APIs. Apps can incorporate advanced features such as rendering
password-protected files, annotations, form editing,
searching, and selection with copy. Linearized PDF
optimizations are supported to speed local PDF viewing and reduce resource use.
The Jetpack PDF library uses these APIs to simplify adding PDF
viewing capabilities to your app.

The PdfRenderer
has been moved to a module that can be updated using Google
Play system updates independent of the platform release, and we're supporting
these changes back to Android 11 (API level 30) by creating a compatible
pre-Android 15 version of the API surface, called
PdfRendererPreV
.
Ulepszenia automatycznego przełączania języka
Android 14 在音频中添加了设备端多语言识别功能,并支持在语言之间自动切换,但这可能会导致丢失字词,尤其是当两次语音之间语言切换的间隔时间较短时。Android 15 添加了其他控件,以帮助应用根据其用例调整此切换。EXTRA_LANGUAGE_SWITCH_INITIAL_ACTIVE_DURATION_TIME_MILLIS
会将自动切换限制在音频会话开始时,而 EXTRA_LANGUAGE_SWITCH_MATCH_SWITCHES
会在发生指定次数的切换后停用语言切换。如果您预计会话期间只会使用一种语言,并且该语言应被自动检测到,这些选项会特别有用。
Ulepszona usługa OpenType Variable Font API
Android 15 提高了 OpenType 可变字体的易用性。现在,您可以
基于可变字体创建 FontFamily
实例,而不指定
使用 buildVariableFamily
API 绘制权重轴。文本渲染程序替换项
wght
轴的值,以与显示的文本匹配。
使用新的 API,这可以简化用于创建 Typeface
的代码
大量:
Kotlin
val newTypeface = Typeface.CustomFallbackBuilder( FontFamily.Builder( Font.Builder(assets, "RobotoFlex.ttf").build()) .buildVariableFamily()) .build()
Java
Typeface newTypeface = Typeface.CustomFallbackBuilder( new FontFamily.Builder( new Font.Builder(assets, "RobotoFlex.ttf").build()) .buildVariableFamily()) .build();
以前,如需创建相同的 Typeface
,您需要更多代码:
Kotlin
val oldTypeface = Typeface.CustomFallbackBuilder( FontFamily.Builder( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 400") .setWeight(400) .build()) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 100") .setWeight(100) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 200") .setWeight(200) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 300") .setWeight(300) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 500") .setWeight(500) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 600") .setWeight(600) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 700") .setWeight(700) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 800") .setWeight(800) .build() ) .addFont( Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 900") .setWeight(900) .build() ).build() ).build()
Java
Typeface oldTypeface = new Typeface.CustomFallbackBuilder( new FontFamily.Builder( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 400") .setWeight(400) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 100") .setWeight(100) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 200") .setWeight(200) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 300") .setWeight(300) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 500") .setWeight(500) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 600") .setWeight(600) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 700") .setWeight(700) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 800") .setWeight(800) .build() ) .addFont( new Font.Builder(assets, "RobotoFlex.ttf") .setFontVariationSettings("'wght' 900") .setWeight(900) .build() ) .build() ).build();
以下示例展示了如何同时使用新旧 API 创建 Typeface
呈现:
在此示例中,使用旧 API 创建的 Typeface
不包含
为 350、450、550 和 650 创建准确的字体粗细
Font
实例,因此渲染程序会回退到最接近的权重。在
在此示例中,系统会渲染 300 而不是 350,渲染 400 而不是 450,
依此类推。相比之下,使用新 API 创建的 Typeface
会动态创建
给定权重的 Font
实例,因此系统会渲染 350 的准确权重,
450、550 和 650。
Szczegółowe ustawienia podziału wiersza
从 Android 15 开始,TextView
和底层行断开符可以将给定部分文本保留在同一行中,以提高可读性。您可以通过在字符串资源或 createNoBreakSpan
中使用 <nobreak>
标记来充分利用此换行符自定义功能。同样,您可以使用 <nohyphen>
标记或 createNoHyphenationSpan
来防止对字词进行分词。
例如,以下字符串资源不包含换行符,在呈现时,文本“Pixel 8 Pro”会在不合适的位置换行:
<resources>
<string name="pixel8pro">The power and brains behind Pixel 8 Pro.</string>
</resources>
相比之下,此字符串资源包含 <nobreak>
标记,该标记会将字词“Pixel 8 Pro”换行,并防止换行:
<resources>
<string name="pixel8pro">The power and brains behind <nobreak>Pixel 8 Pro.</nobreak></string>
</resources>
以下图片展示了这些字符串呈现方式的差异:

<nobreak>
标记换行。
<nobreak>
标记封装“Pixel 8 Pro.”短语的同一行文本的布局。Archiwizacja aplikacji
Android and Google Play announced support for app archiving last year, allowing users to free up space by partially removing infrequently used apps from the device that were published using Android App Bundle on Google Play. Android 15 includes OS level support for app archiving and unarchiving, making it easier for all app stores to implement it.
Apps with the REQUEST_DELETE_PACKAGES
permission can call the
PackageInstaller
requestArchive
method to request archiving an
installed app package, which removes the APK and any cached files, but persists
user data. Archived apps are returned as displayable apps through the
LauncherApps
APIs; users will see a UI treatment to highlight that those
apps are archived. If a user taps on an archived app, the responsible installer
will get a request to unarchive it, and the restoration process can be
monitored by the ACTION_PACKAGE_ADDED
broadcast.
使用开发者选项在设备上启用 16 KB 模式

切换以 16KB 页面大小启动设备开发者选项,以便在 16 KB 模式下启动设备。
从 Android 15 QPR1 开始,您可以使用某些设备上提供的开发者选项,以 16 KB 模式启动设备并执行设备端测试。在使用开发者选项之前,请依次前往“设置”->“系统”->“软件更新”,然后应用所有可用的更新。
此开发者选项适用于以下设备:
Pixel 8 和 Pixel 8 Pro(搭载 Android 15 QPR1 或更高版本)
警告:由于 Android 15 QPR2 Beta 版 3 存在已知问题,在安装 Android 15 QPR2 Beta 版 3 并以 16 KB 模式启动设备后,Pixel 8 设备上的触摸屏无法正常使用。此问题不会影响 Pixel 8 Pro 设备。
Pixel 8a(搭载 Android 15 QPR1 或更高版本)
警告:由于 Android 15 QPR2 Beta 版 3 存在已知问题,在安装 Android 15 QPR2 Beta 版 3 并以 16 KB 模式启动设备后,Pixel 8a 设备上的触摸屏无法正常使用。

Grafika
Android 15 wprowadza najnowsze ulepszenia grafiki, w tym ANGLE i dodatkowe funkcje systemu graficznego Canvas.
Uaktualnianie dostępu do GPU w Androidzie
Android hardware has evolved quite a bit from the early days where the core OS would run on a single CPU and GPUs were accessed using APIs based on fixed-function pipelines. The Vulkan® graphics API has been available in the NDK since Android 7.0 (API level 24) with a lower-level abstraction that better reflects modern GPU hardware, scales better to support multiple CPU cores, and offers reduced CPU driver overhead — leading to improved app performance. Vulkan is supported by all modern game engines.
Vulkan is Android's preferred interface to the GPU. Therefore, Android 15 includes ANGLE as an optional layer for running OpenGL® ES on top of Vulkan. Moving to ANGLE will standardize the Android OpenGL implementation for improved compatibility, and, in some cases, improved performance. You can test out your OpenGL ES app stability and performance with ANGLE by enabling the developer option in Settings -> System -> Developer Options -> Experimental: Enable ANGLE on Android 15.
The Android ANGLE on Vulkan roadmap

As part of streamlining our GPU stack, going forward we will be shipping ANGLE as the GL system driver on more new devices, with the future expectation that OpenGL/ES will be only available through ANGLE. That being said, we plan to continue support for OpenGL ES on all devices.
Recommended next steps
Use the developer options to select the ANGLE driver for OpenGL ES and test your app. For new projects, we strongly encourage using Vulkan for C/C++.
Ulepszenia dotyczące Canvas
Android 15 继续对 Android 的 Canvas 图形系统进行现代化改造,并新增了以下功能:
Matrix44
提供一个 4x4 矩阵来转换坐标,当您想在 3D 中操控画布时,应使用此矩阵。clipShader
会将当前剪裁区域与指定的着色器相交,而clipOutShader
会将剪裁区域设为当前剪裁区域与着色器的差值,每个操作都会将着色器视为一个 Alpha 遮罩。这支持高效地绘制复杂形状。
Wydajność i bateria
Android nadal pomaga Ci poprawiać wydajność i jakość aplikacji. Android 15 wprowadza interfejsy API, które pomagają zwiększyć wydajność zadań w aplikacji, zoptymalizować jej działanie i zbierać statystyki dotyczące aplikacji.
Aby dowiedzieć się więcej o sprawdzonym sposobie oszczędzania baterii, debugowaniu sieci i zużycia energii oraz o tym, jak zwiększamy wydajność baterii w procesach działających w tle w Androidzie 15 i nowszych wersjach, obejrzyj wykład Zwiększanie wydajności baterii w procesach działających w tle na Androidzie z Google I/O.
ApplicationStartInfo API
在以前的 Android 版本中,应用启动一直是个谜。在应用中确定应用是从冷启动、温启动还是热启动状态启动很困难。您还很难了解应用在各种启动阶段(分叉进程、调用 onCreate
、绘制第一个帧等)所花的时间。在 Application
类被实例化时,您无法知道应用是通过广播、content provider、作业、备份、启动完成、闹钟还是 Activity
启动的。
Android 15 上的 ApplicationStartInfo
API 提供了所有这些功能,以及更多功能。您甚至可以选择在流程中添加自己的时间戳,以便在一个位置收集时间数据。除了收集指标之外,您还可以使用 ApplicationStartInfo
直接优化应用启动;例如,您可以消除在应用因广播而启动时在 Application
类中实例化与界面相关的库所带来的高昂开销。
Szczegółowe informacje o rozmiarze aplikacji
从 Android 8.0(API 级别 26)开始,Android 包含 StorageStats.getAppBytes
API,该 API 会将应用的安装大小总结为一个字节数,该数值是 APK 大小、从 APK 中提取的文件的大小以及在设备上生成的文件(例如提前编译 [AOT] 代码)的总和。此数字对于了解应用的存储空间使用情况而言,没有太大帮助。
Android 15 添加了 StorageStats.getAppBytesByDataType([type])
API,可让您深入了解应用如何使用所有这些空间,包括 APK 文件分块、AOT 和加速相关代码、DEX 元数据、库和引导式配置文件。
Profilowanie zarządzane przez aplikację
Android 15 includes the ProfilingManager
class,
which lets you collect profiling information from within your app such as heap
dumps, heap profiles, stack sampling, and more. It provides a callback to your
app with a supplied tag to identify the output file, which is delivered to your
app's files directory. The API does rate limiting to minimize the performance
impact.
To simplify constructing profiling requests in your app, we recommend using the
corresponding Profiling
AndroidX API, available
in Core 1.15.0-rc01 or higher.
Ulepszenia bazy danych SQLite
Android 15 引入了 SQLite API,这些 API 可公开底层 SQLite 引擎的高级功能,以解决可能在应用中出现的特定性能问题。将 SQLite 更新到版本 3.44.3。

事务并发运行。 - 行数和 ID:添加了 API 以检索已更改的行数和 ID
行或最后插入的行 ID 而不发出额外的查询。
getLastChangedRowCount()
会返回当前事务中最近的 SQL 语句插入、更新或删除的行数,而getTotalChangedRowCount()
会返回当前连接的计数。getLastInsertRowId()
返回最后一行的rowid
以便在当前连接中插入 - 原始语句:发出原始 SQlite 语句,从而绕过便利 及其可能产生的任何额外处理开销。
Aktualizacje Android Dynamic Performance Framework
Android 15 继续投资于 Android 动态性能框架 (ADPF),这是一组 API,可让游戏和性能密集型应用更为直接地与 Android 设备的电源和散热系统进行互动。在受支持的设备上,Android 15 添加了 ADPF 功能:
- 针对提示会话的节能模式,用于指明其关联的线程应优先节能而非性能,非常适合长时间运行的后台工作负载。
- 系统可以在提示会话中报告 GPU 和 CPU 工作时长,以便同时调整 CPU 和 GPU 频率,以最佳方式满足工作负载需求。
- 热余量阈值,用于根据余量预测来解读可能的热节流状态。
如需详细了解如何在应用和游戏中使用 ADPF,请参阅相关文档。
Prywatność
Android 15 zawiera wiele funkcji, które pomagają deweloperom aplikacji chronić prywatność użytkowników.
Wykrywanie nagrywania ekranu
Android 15 增加了对应用的支持,以检测 正在录制。每当应用转换时,系统都会调用回调 在屏幕录制内容中处于可见与隐藏状态之间。如果正在记录注册进程的 UID 拥有的 activity,则系统会将应用视为可见。这样一来,如果您的应用执行敏感操作,您就可以告知用户正在录制他们的操作。
val mCallback = Consumer<Int> { state ->
if (state == SCREEN_RECORDING_STATE_VISIBLE) {
// We're being recorded
} else {
// We're not being recorded
}
}
override fun onStart() {
super.onStart()
val initialState =
windowManager.addScreenRecordingCallback(mainExecutor, mCallback)
mCallback.accept(initialState)
}
override fun onStop() {
super.onStop()
windowManager.removeScreenRecordingCallback(mCallback)
}
Rozszerzone możliwości IntentFilter
Android 15 通过 UriRelativeFilterGroup
支持更精确的 Intent
解析,UriRelativeFilterGroup
包含一组 UriRelativeFilter
对象,这些对象构成一组必须满足的 Intent
匹配规则,包括网址查询参数、网址片段以及屏蔽或排除规则。
您可以在 AndroidManifest
XML 文件中使用 <uri-relative-filter-group>
标记来定义这些规则,该标记可以包含 android:allow
标记。这些代码可以包含使用现有数据代码属性以及 android:query
和 android:fragment
属性的 <data>
代码。
下面是一个 AndroidManifest
语法示例:
<intent-filter>
<action android:name="android.intent.action.VIEW" />

Przestrzeń prywatna
借助私密空间,用户可以在设备上创建一个单独的空间,在额外的身份验证层保护下,防止敏感应用遭到窥探。私密空间使用单独的用户个人资料。用户可以选择使用设备锁定方式或为私密空间使用单独的锁定方式。
私密空间中的应用会显示在启动器的单独容器中,并且当私密空间处于锁定状态时,这些应用不会显示在“最近用过”视图、通知、“设置”和其他应用中。用户生成的内容和下载的内容(例如媒体内容或文件)以及账号在私密空间和主空间之间是分开的。在私密空间处于解锁状态时,您可以使用系统 Sharesheet 和照片选择器向应用授予对各个空间中内容的访问权限。
用户无法将现有应用及其数据移至私密空间。相反,用户可以在私密空间中选择安装选项,以便使用他们偏好的任意应用商店安装应用。私密空间中的应用会作为主空间中任何应用的单独副本进行安装(同一应用的新副本)。
当用户锁定私密空间时,系统会停止该个人资料。在个人资料停止运行时,私密空间中的应用将不再处于活动状态,无法执行前台或后台活动,包括显示通知。
我们建议您使用私密空间测试应用,以确保应用能按预期运行,尤其是当您的应用属于以下某一类别时:
- 具有工作资料逻辑的应用:假定其应用的任何已安装副本(不在主资料中)均位于工作资料中。
- 医疗应用
- 启动器应用
- 应用商店应用

Bardziej rozbudowane podglądy widżetów dzięki interfejsowi Generated Previews API
Before Android 15, the only way to provide widget picker previews was to specify a static image or layout resource. These previews often differ significantly from the look of the actual widget when it is placed on the home screen. Also, static resources can't be created with Jetpack Glance, so a Glance developer had to screenshot their widget or create an XML layout to have a widget preview.
Android 15 adds support for generated previews. This means that app widget
providers can generate RemoteViews
to use as the picker preview, instead
of a static resource.

Push API
Apps can provide generated previews through a push API. Apps can provide
previews at any point in their lifecycle, and don't receive an explicit request
from the host to provide previews. Previews are persisted in AppWidgetService
,
and hosts can request them on-demand. The following example loads an XML widget
layout resource and sets it as the preview:
AppWidgetManager.getInstance(appContext).setWidgetPreview(
ComponentName(
appContext,
SociaLiteAppWidgetReceiver::class.java
),
AppWidgetProviderInfo.WIDGET_CATEGORY_HOME_SCREEN,
RemoteViews("com.example", R.layout.widget_preview)
)
The expected flow is:
- At any time, the widget provider calls
setWidgetPreview
. The provided previews are persisted inAppWidgetService
with other provider info. setWidgetPreview
notifies hosts of an updated preview through theAppWidgetHost.onProvidersChanged
callback. In response, the widget host reloads all of its provider information.- When displaying a widget preview, the host checks
AppWidgetProviderInfo.generatedPreviewCategories
, and if the chosen category is available, callsAppWidgetManager.getWidgetPreview
to return the saved preview for this provider.
When to call setWidgetPreview
Because there is no callback to provide previews, apps can choose to send previews at any point when they are running. How often to update the preview depends on the widget's use case.
The following list describes the two main categories of preview use cases:
- Providers that show real data in their widget previews, such as personalized or recent information. These providers can set the preview once the user has signed in or has done initial configuration in their app. After this, they can set up a periodic task to update the previews at their chosen cadence. Examples of this type of widget could be a photo, calendar, weather or news widget.
- Providers that show static information in previews or quick-action widgets that don't display any data. These providers can set previews once, when the app first launches. Examples of this type of widget include a drive quick actions widget or chrome shortcuts widget.
Some providers might show static previews on the hub mode picker, but real information on the homescreen picker. These providers should follow the guidance for both of these use cases to set previews.

Android 15 introduces changes in Picture-in-Picture (PiP) ensuring an even smoother transition when entering into PiP mode. This will be beneficial for apps having UI elements overlaid on top of their main UI, which goes into PiP.
Developers use the onPictureInPictureModeChanged
callback to define logic
that toggles the visibility of the overlaid UI elements. This callback is
triggered when the PiP enter or exit animation is completed. Beginning in
Android 15, the PictureInPictureUiState
class includes another state.
With this UI state, apps targeting Android 15 (API level 35) will observe the
Activity#onPictureInPictureUiStateChanged
callback being invoked with
isTransitioningToPip()
as soon as the PiP animation starts. There are
many UI elements that are not relevant for the app when it is in PiP mode, for
example views or layout that include information such as suggestions, upcoming
video, ratings, and titles. When the app goes to PiP mode, use the
onPictureInPictureUiStateChanged
callback to hide these UI elements. When the
app goes to full screen mode from the PiP window, use
onPictureInPictureModeChanged
callback to unhide these elements, as shown in
the following examples:
override fun onPictureInPictureUiStateChanged(pipState: PictureInPictureUiState) {
if (pipState.isTransitioningToPip()) {
// Hide UI elements
}
}
override fun onPictureInPictureModeChanged(isInPictureInPictureMode: Boolean) {
if (isInPictureInPictureMode) {
// Unhide UI elements
}
}
This quick visibility toggle of irrelevant UI elements (for a PiP window) helps ensure a smoother and flicker-free PiP enter animation.

płynniejsze korzystanie z NFC,
Android 15 is working to make the tap to pay experience more seamless and
reliable while continuing to support Android's robust NFC app ecosystem. On
supported devices, apps can request the NfcAdapter
to enter
observe mode, where the device listens but doesn't respond to NFC
readers, sending the app's NFC service PollingFrame
objects to process. The PollingFrame
objects can be used to auth
ahead of the first communication to the NFC reader, allowing for a one tap
transaction in many cases.
In addition, apps can register a filter on supported devices so they can be notified of polling loop activity, which allows for smooth operation with multiple NFC-aware applications.
Rola portfela
Android 15 introduces a Wallet role that allows tighter integration with the user's preferred wallet app. This role replaces the NFC default contactless payment setting. Users can manage the Wallet role holder by navigating to Settings > Apps > Default Apps.
The Wallet role is used when routing NFC taps for AIDs registered in the payment category. Taps always go to the Wallet role holder unless another app that is registered for the same AID is running in the foreground.
This role is also used to determine where the Wallet Quick Access tile should go when activated. When the role is set to "None", the Quick Access tile isn't available and payment category NFC taps are only delivered to the foreground app.

Integracja Menedżera danych logowania z autouzupełnianiem
Począwszy od Androida 15 deweloperzy mogą połączyć określone widoki, takie jak pola nazwy użytkownika lub hasła, z żądaniami menedżera danych uwierzytelniających, co ułatwia dostosowanie interfejsu do potrzeb użytkownika podczas procesu logowania. Gdy użytkownik skupi się na jednym z tych widoków, do Menedżera danych logowania zostanie wysłane odpowiednie żądanie. Uzyskane dane są agregowane w ramach dostawców i wyświetlane w interfejsach autouzupełniania, takich jak sugestie w polu tekstowym lub sugestie w menu. Biblioteka Jetpack androidx.credentials to preferowany punkt końcowy dla deweloperów. Wkrótce będzie ona dostępna w celu dalszego ulepszania tej funkcji w Androidzie 15 i nowszych.

Starting with Android 15, the font file for Chinese, Japanese, and Korean (CJK) languages, NotoSansCJK, is now a variable font. Variable fonts open up possibilities for creative typography in CJK languages. Designers can explore a broader range of styles and create visually striking layouts that were previously difficult or impossible to achieve.

Uzasadnienie dotyczące znaków pośrednich
Starting with Android 15, text can be justified utilizing letter spacing by
using JUSTIFICATION_MODE_INTER_CHARACTER
. Inter-word justification was
first introduced in Android 8.0 (API level 26), and inter-character
justification provides similar capabilities for languages that use the
whitespace character for segmentation, such as Chinese, Japanese, and others.

.Konfiguracja automatycznego podziału wiersza
Android started supporting phrase-based line breaks for Japanese and Korean in
Android 13 (API level 33). However, while phrase-based line breaks improve the
readability of short lines of text, they don't work well for long lines of text.
In Android 15, apps can apply phrase-based line breaks only for short lines
of text, using the LINE_BREAK_WORD_STYLE_AUTO
option. This option selects the best word style option for the text.
For short lines of text, phrase-based line breaks are used, functioning the same
as LINE_BREAK_WORD_STYLE_PHRASE
, as shown in the
following image:

LINE_BREAK_WORD_STYLE_AUTO
applies phrase-based line breaks to improve the readability of the text.
This is the same as applying
LINE_BREAK_WORD_STYLE_PHRASE
.For longer lines of text, LINE_BREAK_WORD_STYLE_AUTO
uses a no
line-break word style, functioning the same as
LINE_BREAK_WORD_STYLE_NONE
, as shown in the
following image:

LINE_BREAK_WORD_STYLE_AUTO
applies no line-break word style to improve the readability of the text.
