Android 15 offre aux développeurs de nouvelles fonctionnalités et API de qualité. Les sections suivantes résument ces fonctionnalités pour vous aider à vous lancer avec les API associées.

Pour obtenir une liste détaillée des API ajoutées, modifiées et supprimées, consultez le rapport de différences des API. Pour en savoir plus sur les API ajoutées, consultez la documentation de référence des API Android. Pour Android 15, recherchez les API ajoutées au niveau d'API 35. Pour savoir dans quels domaines les changements de plate-forme peuvent affecter vos applications, consultez les modifications de comportement d'Android 15pour les applications ciblant Android 15 et pour toutes les applications.

Appareil photo et médias

Android 15 inclut diverses fonctionnalités qui améliorent l'expérience de l'appareil photo et des contenus multimédias, et qui vous donnent accès à des outils et du matériel pour aider les créateurs à donner vie à leur vision sur Android.

Pour en savoir plus sur les dernières fonctionnalités et solutions pour les développeurs pour les contenus multimédias et l'appareil photo Android, consultez la présentation Créer des expériences multimédias et d'appareil photo Android modernes de Google I/O.

Amplification luminosité faible

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.

Commandes de la caméra dans l'application

Android 15 ajoute une extension pour un meilleur contrôle du matériel de l'appareil photo et de ses algorithmes sur les appareils compatibles:

  • Ajustements avancés de l'intensité du flash permettant de contrôler précisément l'intensité du flash en mode SINGLE et TORCH lors de la prise de vue.

Contrôle de la plage dynamique HDR

Android 15 choisit la plage dynamique appropriée pour les fonctionnalités de l'appareil sous-jacent et la profondeur de bits du panneau. Pour les pages contenant beaucoup de contenu SDR, comme une application de messagerie affichant une seule vignette HDR, ce comportement peut avoir un impact négatif sur la luminosité perçue du contenu SDR. Android 15 vous permet de contrôler la plage dynamique HDR avec setDesiredHdrHeadroom pour trouver un équilibre entre le contenu SDR et HDR.

La luminosité des éléments d'interface utilisateur SDR de l'écran de gauche semble plus uniforme que celle de l'écran de droite, ce qui simule d'éventuels problèmes de plage dynamique lorsque des contenus HDR et SDR sont mélangés. En ajustant la plage dynamique HDR, vous pouvez obtenir un meilleur équilibre entre les contenus SDR et HDR.

Contrôle du volume

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.

Appareils MIDI 2.0 virtuels

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.

Décodage logiciel AV1 plus efficace

dav1d logo

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.

Productivité et outils pour les développeurs

Bien que la plupart de nos efforts visant à améliorer votre productivité soient axés sur des outils tels que Android Studio, Jetpack Compose et les bibliothèques Android Jetpack, nous cherchons toujours à trouver des moyens de vous aider à réaliser plus facilement votre vision.

Mises à jour 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:

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.

Améliorations apportées aux fichiers PDF

Android 15 apporte des améliorations substantielles aux API PdfRenderer. Les applications peuvent intégrer des fonctionnalités avancées telles que l'affichage de fichiers protégés par un mot de passe, les annotations, la modification de formulaire, la recherche et la sélection avec copie. Les optimisations linéarisées des PDF sont compatibles pour accélérer l'affichage des PDF en local et réduire l'utilisation des ressources.

Les dernières mises à jour apportées au rendu PDF incluent des fonctionnalités telles que la recherche dans un fichier PDF intégré.

PdfRenderer a été déplacé vers un module qui peut être mis à jour à l'aide des mises à jour du système Google Play indépendamment de la version de la plate-forme. Nous acceptons ces modifications à nouveau sur Android 11 (niveau d'API 30) en créant une version de surface d'API compatible antérieure à Android 15, appelée PdfRendererPreV.

Vos commentaires sur les améliorations que nous avons apportées à la surface de l'API PdfRenderer nous intéressent, et nous prévoyons de faciliter l'intégration de ces API dans votre application avec une prochaine bibliothèque Android Jetpack.

Améliorations du changement de langue automatique

Android 14 added on-device, multi-language recognition in audio with automatic switching between languages, but this can cause words to get dropped, especially when languages switch with less of a pause between the two utterances. Android 15 adds additional controls to help apps tune this switching to their use case. EXTRA_LANGUAGE_SWITCH_INITIAL_ACTIVE_DURATION_TIME_MILLIS confines the automatic switching to the beginning of the audio session, while EXTRA_LANGUAGE_SWITCH_MATCH_SWITCHES deactivates the language switching after a defined number of switches. These options are particularly useful if you expect that there will be a single language spoken during the session that should be autodetected.

Amélioration de l'API OpenType Variable Font

Android 15 improves the usability of the OpenType variable font. You can create a FontFamily instance from a variable font without specifying weight axes with the buildVariableFamily API. The text renderer overrides the value of wght axis to match the displaying text.

Using the API simplifies the code for creating a Typeface considerably:

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();

Previously, to create the same Typeface, you would need much more code:

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();

Here's an example of how a Typeface created with both the old and new APIs renders:

An example of how Typeface rendering differs using new and old APIs

In this example, the Typeface created with the old API doesn't have the capability to create accurate font weights for the 350, 450, 550 and 650 Font instances, so the renderer falls back to the closest weight. So in this case, 300 is rendered instead of 350, 400 is rendered instead of 450, and so on. By contrast, the Typeface created with the new APIs dynamically creates a Font instance for a given weight, so accurate weights are rendered for 350, 450, 550, and 650 as well.

Contrôles précis des sauts de ligne

À partir d'Android 15, un TextView et le séparateur de ligne sous-jacent peuvent conserver la partie de texte donnée sur la même ligne pour améliorer la lisibilité. Vous pouvez profiter de cette personnalisation de la casse en utilisant la balise <nobreak> dans les ressources de chaîne ou createNoBreakSpan. De même, vous pouvez empêcher la césure des mots à l'aide de la balise <nohyphen> ou createNoHyphenationSpan.

Par exemple, la ressource de chaîne suivante n'inclut pas de saut de ligne et s'affiche avec le texte "Pixel 8 Pro." qui se brise à un endroit indésirable:

<resources>
    <string name="pixel8pro">The power and brains behind Pixel 8 Pro.</string>
</resources>

En revanche, cette ressource de chaîne inclut la balise <nobreak>, qui affiche la phrase "Pixel 8 Pro" et empêche les sauts de ligne:

<resources>
    <string name="pixel8pro">The power and brains behind <nobreak>Pixel 8 Pro.</nobreak></string>
</resources>

La différence d'affichage de ces chaînes est illustrée dans les images suivantes:

Mise en page pour une ligne de texte dans laquelle l'expression "Pixel 8 Pro" n'est pas enveloppée à l'aide d'une balise <nobreak>.
Mise en page de la même ligne de texte où la phrase "Pixel 8 Pro." est mise en forme à l'aide d'une balise <nobreak>.

Archivage des applications

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.

Graphiques

Android 15 apporte les dernières améliorations graphiques, y compris ANGLE et des ajouts au système graphique Canvas.

Moderniser l'accès au GPU d'Android

Vulkan logo

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

Roadmap of upcoming changes to the Android GPU APIs.

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++.

Améliorations apportées à Canvas

Android 15 continues our modernization of Android's Canvas graphics system with additional capabilities:

  • Matrix44 provides a 4x4 matrix for transforming coordinates that should be used when you want to manipulate the canvas in 3D.
  • clipShader intersects the current clip with the specified shader, while clipOutShader sets the clip to the difference of the current clip and the shader, each treating the shader as an alpha mask. This supports the drawing of complex shapes efficiently.

Performances et batterie

Android continue de vous aider à améliorer les performances et la qualité de vos applications. Android 15 introduit des API qui permettent d'exécuter les tâches de votre application plus efficacement, d'optimiser ses performances et de collecter des insights sur vos applications.

Pour découvrir les bonnes pratiques d'économie d'énergie, le débogage de l'utilisation du réseau et de l'alimentation, et comment nous améliorons l'efficacité énergétique des tâches en arrière-plan dans Android 15 et les versions récentes d'Android, consultez la présentation Améliorer l'efficacité énergétique des tâches en arrière-plan sur Android de Google I/O.

API ApplicationStartInfo

Dans les versions précédentes d'Android, le démarrage des applications était un peu mystérieux. Il était difficile de déterminer dans votre application si elle a démarré à partir d'un état à froid, tiède ou chaud. Il était également difficile de savoir combien de temps votre application a passé pendant les différentes phases de lancement: forking du processus, appel de onCreate, dessin du premier frame, etc. Lorsque votre classe Application a été instanciée, vous ne pouviez pas savoir si l'application a démarré à partir d'une diffusion, d'un fournisseur de contenu, d'une tâche, d'une sauvegarde, d'un démarrage terminé, d'une alarme ou d'un Activity.

L'API ApplicationStartInfo sur Android 15 fournit tout cela et plus encore. Vous pouvez même choisir d'ajouter vos propres codes temporels dans le flux pour collecter les données temporelles au même endroit. En plus de collecter des métriques, vous pouvez utiliser ApplicationStartInfo pour optimiser directement le démarrage de l'application. Par exemple, vous pouvez éliminer l'instanciation coûteuse des bibliothèques liées à l'UI dans votre classe Application lorsque votre application démarre en raison d'une diffusion.

Informations détaillées sur la taille de l'application

Depuis Android 8.0 (niveau d'API 26), Android inclut l'API StorageStats.getAppBytes, qui résume la taille installée d'une application en un seul nombre d'octets, qui correspond à la somme de la taille de l'APK, de la taille des fichiers extraits de l'APK et des fichiers générés sur l'appareil, tels que le code compilé à l'avance (AOT). Ce nombre n'est pas très révélateur de la façon dont votre application utilise l'espace de stockage.

Android 15 ajoute l'API StorageStats.getAppBytesByDataType([type]), qui vous permet d'obtenir des informations sur la façon dont votre application utilise tout cet espace, y compris les fractionnements de fichiers APK, le code lié à l'AOT et à l'accélération, les métadonnées dex, les bibliothèques et les profils guidés.

Profilage géré par l'application

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.

Améliorations apportées à la base de données SQLite

Android 15 introduces SQLite APIs that expose advanced features from the underlying SQLite engine that target specific performance issues that can manifest in apps. These APIs are included with the update of SQLite to version 3.44.3.

Developers should consult best practices for SQLite performance to get the most out of their SQLite database, especially when working with large databases or when running latency-sensitive queries.

  • Read-only deferred transactions: when issuing transactions that are read-only (don't include write statements), use beginTransactionReadOnly() and beginTransactionWithListenerReadOnly(SQLiteTransactionListener) to issue read-only DEFERRED transactions. Such transactions can run concurrently with each other, and if the database is in WAL mode, they can run concurrently with IMMEDIATE or EXCLUSIVE transactions.
  • Row counts and IDs: APIs were added to retrieve the count of changed rows or the last inserted row ID without issuing an additional query. getLastChangedRowCount() returns the number of rows that were inserted, updated, or deleted by the most recent SQL statement within the current transaction, while getTotalChangedRowCount() returns the count on the current connection. getLastInsertRowId() returns the rowid of the last row to be inserted on the current connection.
  • Raw statements: issue a raw SQlite statement, bypassing convenience wrappers and any additional processing overhead that they may incur.

Mises à jour d'Android Dynamic Performance Framework

Android 15 continues our investment in the Android Dynamic Performance Framework (ADPF), a set of APIs that allow games and performance intensive apps to interact more directly with power and thermal systems of Android devices. On supported devices, Android 15 adds ADPF capabilities:

  • A power-efficiency mode for hint sessions to indicate that their associated threads should prefer power saving over performance, great for long-running background workloads.
  • GPU and CPU work durations can both be reported in hint sessions, allowing the system to adjust CPU and GPU frequencies together to best meet workload demands.
  • Thermal headroom thresholds to interpret possible thermal throttling status based on headroom prediction.

To learn more about how to use ADPF in your apps and games, head over to the documentation.

Confidentialité

Android 15 inclut diverses fonctionnalités qui aident les développeurs d'applications à protéger la confidentialité des utilisateurs.

Détection d'enregistrement d'écran

Android 15 adds support for apps to detect that they are being recorded. A callback is invoked whenever the app transitions between being visible or invisible within a screen recording. An app is considered visible if activities owned by the registering process's UID are being recorded. This way, if your app is performing a sensitive operation, you can inform the user that they're being recorded.

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)
}

Fonctionnalités IntentFilter étendues

Android 15 builds in support for more precise Intent resolution through UriRelativeFilterGroup, which contains a set of UriRelativeFilter objects that form a set of Intent matching rules that must each be satisfied, including URL query parameters, URL fragments, and blocking or exclusion rules.

These rules can be defined in the AndroidManifest XML file with the <uri-relative-filter-group> tag, which can optionally include an android:allow tag. These tags can contain <data> tags that use existing data tag attributes as well as the android:query and android:fragment attributes.

Here's an example of the AndroidManifest syntax:

<intent-filter android:autoVerify="true">
  <action android:name="android.intent.action.VIEW" />
  <category android:name="android.intent.category.BROWSABLE" />
  <category android:name="android.intent.category.DEFAULT" />
  <data android:scheme="http" />
  <data android:scheme="https" />
  <data android:host="astore.com" />
  <uri-relative-filter-group>
    <data android:pathPrefix="/auth" />
    <data android:query="region=na" />
  </uri-relative-filter-group>

Espace privé

The private space can be unlocked and locked to show or hide sensitive apps on a device.

Private space lets users create a separate space on their device where they can keep sensitive apps away from prying eyes, under an additional layer of authentication. The private space uses a separate user profile. The user can choose to use the device lock or a separate lock factor for the private space.

Apps in the private space show up in a separate container in the launcher, and are hidden from the recents view, notifications, settings, and from other apps when the private space is locked. User-generated and downloaded content (such as media or files) and accounts are separated between the private space and the main space. The system sharesheet and the photo picker can be used to give apps access to content across spaces when the private space is unlocked.

Users can't move existing apps and their data into the private space. Instead, users select an install option in the private space to install an app using whichever app store they prefer. Apps in the private space are installed as separate copies from any apps in the main space (new copies of the same app).

When a user locks the private space, the profile is stopped. While the profile is stopped, apps in the private space are no longer active and can't perform foreground or background activities, including showing notifications.

We recommend that you test your app with private space to make sure your app works as expected, especially if your app falls into one of the following categories:

Interroger la dernière sélection de l'utilisateur pour l'accès aux photos sélectionnées

Apps can now highlight only the most-recently-selected photos and videos when partial access to media permissions is granted. This feature can improve the user experience for apps that frequently request access to photos and videos. To use this feature in your app, enable the QUERY_ARG_LATEST_SELECTION_ONLY argument when querying MediaStore through ContentResolver.

Kotlin

val externalContentUri = MediaStore.Files.getContentUri("external")

val mediaColumns = arrayOf(
   FileColumns._ID,
   FileColumns.DISPLAY_NAME,
   FileColumns.MIME_TYPE,
)

val queryArgs = bundleOf(
   // Return only items from the last selection (selected photos access)
   QUERY_ARG_LATEST_SELECTION_ONLY to true,
   // Sort returned items chronologically based on when they were added to the device's storage
   QUERY_ARG_SQL_SORT_ORDER to "${FileColumns.DATE_ADDED} DESC",
   QUERY_ARG_SQL_SELECTION to "${FileColumns.MEDIA_TYPE} = ? OR ${FileColumns.MEDIA_TYPE} = ?",
   QUERY_ARG_SQL_SELECTION_ARGS to arrayOf(
       FileColumns.MEDIA_TYPE_IMAGE.toString(),
       FileColumns.MEDIA_TYPE_VIDEO.toString()
   )
)

Java

Uri externalContentUri = MediaStore.Files.getContentUri("external");

String[] mediaColumns = {
    FileColumns._ID,
    FileColumns.DISPLAY_NAME,
    FileColumns.MIME_TYPE
};

Bundle queryArgs = new Bundle();
queryArgs.putBoolean(MediaStore.QUERY_ARG_LATEST_SELECTION_ONLY, true);
queryArgs.putString(MediaStore.QUERY_ARG_SQL_SORT_ORDER, FileColumns.DATE_ADDED + " DESC");
queryArgs.putString(MediaStore.QUERY_ARG_SQL_SELECTION, FileColumns.MEDIA_TYPE + " = ? OR " + FileColumns.MEDIA_TYPE + " = ?");
queryArgs.putStringArray(MediaStore.QUERY_ARG_SQL_SELECTION_ARGS, new String[] {
    String.valueOf(FileColumns.MEDIA_TYPE_IMAGE),
    String.valueOf(FileColumns.MEDIA_TYPE_VIDEO)
});

Partager le contenu d'une appli sur l'écran

Android 15 supports app screen sharing so users can share or record just an app window rather than the entire device screen. This feature, first enabled in Android 14 QPR2, includes MediaProjection callbacks that allow your app to customize the app screen sharing experience. Note that for apps targeting Android 14 (API level 34) or higher, user consent is required for each MediaProjection capture session.

Aperçus de widgets plus riches avec l'API Generated Previews

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.

Apps can provide Remote Views to the Widget Picker, so they can update the content in the picker to be more representative of what the user will see.

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:

  1. At any time, the widget provider calls setWidgetPreview. The provided previews are persisted in AppWidgetService with other provider info.
  2. setWidgetPreview notifies hosts of an updated preview through the AppWidgetHost.onProvidersChanged callback. In response, the widget host reloads all of its provider information.
  3. When displaying a widget preview, the host checks AppWidgetProviderInfo.generatedPreviewCategories, and if the chosen category is available, calls AppWidgetManager.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.

Picture-in-picture

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.

Règles du mode Ne pas déranger améliorées

AutomaticZenRule lets apps customize Attention Management (Do Not Disturb) rules and decide when to activate or deactivate them. Android 15 greatly enhances these rules with the goal of improving the user experience. The following enhancements are included:

  • Adding types to AutomaticZenRule, allowing the system to apply special treatment to some rules.
  • Adding an icon to AutomaticZenRule, helping to make the modes be more recognizable.
  • Adding a triggerDescription string to AutomaticZenRule that describes the conditions on which the rule should become active for the user.
  • Added ZenDeviceEffects to AutomaticZenRule, allowing rules to trigger things like grayscale display, night mode, or dimming the wallpaper.

Définir VibrationEffect pour les canaux de notification

Android 15 supports setting rich vibrations for incoming notifications by channel using NotificationChannel.setVibrationEffect, so your users can distinguish between different types of notifications without having to look at their device.

Chip de la barre d'état de la projection multimédia et arrêt automatique

La projection multimédia peut exposer des informations personnelles des utilisateurs. Un nouveau chip de barre d'état proéminent informe les utilisateurs de toute projection d'écran en cours. Les utilisateurs peuvent appuyer sur le chip pour arrêter la diffusion, le partage ou l'enregistrement de l'écran. De plus, pour une expérience utilisateur plus intuitive, toute projection d'écran en cours s'arrête désormais automatiquement lorsque l'écran de l'appareil est verrouillé.

Chip de la barre d'état pour le partage d'écran, la diffusion et l'enregistrement.

Grands écrans et facteurs de forme

Android 15 permet à vos applications de tirer le meilleur parti des facteurs de forme d'Android, y compris les grands écrans, les téléphones à clapet et les pliables.

Amélioration du multitâche sur grand écran

Android 15 offre aux utilisateurs de meilleurs moyens d'effectuer plusieurs tâches en même temps sur les appareils à grand écran. Pour Par exemple, les utilisateurs peuvent enregistrer leurs combinaisons d'applications en écran partagé préférées pour des accéder à la barre des tâches et l'épingler à l'écran pour passer rapidement d'une application à l'autre. Il est donc plus important que jamais de vous assurer que votre application est adaptative.

Google I/O propose des sessions sur la création d'applications Android adaptatives applications et Créer une interface utilisateur avec Material 3 bibliothèque adaptative et notre documentation peut vous aider. Concevoir pour les grands écrans.

Compatibilité avec l'écran de couverture

Your app can declare a property that Android 15 uses to allow your Application or Activity to be presented on the small cover screens of supported flippable devices. These screens are too small to be considered as compatible targets for Android apps to run on, but your app can opt in to supporting them, making your app available in more places.

Connectivité

Android 15 met à jour la plate-forme pour donner à votre application accès aux dernières avancées en matière de communication et de technologies sans fil.

Assistance par satellite

Android 15 continues to extend platform support for satellite connectivity and includes some UI elements to ensure a consistent user experience across the satellite connectivity landscape.

Apps can use ServiceState.isUsingNonTerrestrialNetwork() to detect when a device is connected to a satellite, giving them more awareness of why full network services might be unavailable. Additionally, Android 15 provides support for SMS and MMS apps as well as preloaded RCS apps to use satellite connectivity for sending and receiving messages.

A notification appears when the device connects to a satellite.

Expériences NFC plus fluides

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.

Rôle de portefeuille

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.

Sécurité

Intégrer le Gestionnaire d'identifiants à la saisie automatique

Starting with Android 15, developers can link specific views like username or password fields with Credential Manager requests, making it easier to provide a tailored user experience during the sign-in process. When the user focuses on one of these views, a corresponding request is sent to Credential Manager. The resulting credentials are aggregated across providers and displayed in autofill fallback UIs, such as inline suggestions or drop-down suggestions. The Jetpack androidx.credentials library is the preferred endpoint for developers to use and will soon be available to further enhance this feature in Android 15 and higher.

Intégrer la connexion et l'inscription en un seul geste avec des invites biométriques

Credential Manager integrates biometric prompts into the credential creation and sign-in processes, eliminating the need for providers to manage biometric prompts. As a result, credential providers only need to focus on the results of the create and get flows, augmented with the biometric flow result. This simplified process creates a more efficient and streamlined credential creation and retrieval process.

Gestion des clés pour le chiffrement de bout en bout

We are introducing the E2eeContactKeysManager in Android 15, which facilitates end-to-end encryption (E2EE) in your Android apps by providing an OS-level API for the storage of cryptographic public keys.

The E2eeContactKeysManager is designed to integrate with the platform contacts app to give users a centralized way to manage and verify their contacts' public keys.

Vérifications des autorisations sur les URI de contenu

Android 15 introduces a set of APIs that perform permission checks on content URIs:

Accessibilité

Android 15 ajoute des fonctionnalités qui améliorent l'accessibilité pour les utilisateurs.

Braille amélioré

In Android 15, we've made it possible for TalkBack to support Braille displays that are using the HID standard over both USB and secure Bluetooth.

This standard, much like the one used by mice and keyboards, will help Android support a wider range of Braille displays over time.

Internationalisation

Android 15 ajoute des fonctionnalités qui complètent l'expérience utilisateur lorsqu'un appareil est utilisé dans différentes langues.

Police variable CJK

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.

How the variable font for Chinese, Japanese, and Korean (CJK) languages appears with different font widths.

Justification entre les caractères

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.

Configuration automatique des coupures de ligne

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:

For short lines of text, 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:

For long lines of text, LINE_BREAK_WORD_STYLE_AUTO applies no line-break word style to improve the readability of the text. This is the same as applying LINE_BREAK_WORD_STYLE_NONE.

Police Hentaigana japonaise supplémentaire

Dans Android 15, un fichier de police pour l'ancien hiragana japonais (appelé Hentaigana) est regroupé par défaut. Les formes uniques des personnages Hentaigana permettent d'ajouter à l'œuvre ou au design, tout en préservant la précision transmission et compréhension des anciens documents japonais.
