Descripción general de las funciones y APIs

Android 15 presenta excelentes funciones y APIs para desarrolladores. En las siguientes secciones, se resumen estas funciones para ayudarte a comenzar a usar las APIs relacionadas.

Cámara y contenido multimedia

Android 15 incluye una variedad de funciones que mejoran la cámara y la experiencia multimedia, y te dan acceso a herramientas y hardware para ayudar a los creadores a hacer realidad su visión en Android.

Aumento con poca luz

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.

Controles de cámara en la app

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 and TORCH modes while capturing images.

Control del margen de HDR

Android 15 chooses HDR headroom that is appropriate for the underlying device capabilities and bit-depth of the panel. For pages that have lots of SDR content, such as a messaging app displaying a single HDR thumbnail, this behavior can end up adversely influencing the perceived brightness of the SDR content. Android 15 lets you control the HDR headroom with setDesiredHdrHeadroom to strike a balance between SDR and HDR content.

Control de volumen

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.

Dispositivos MIDI virtuales 2.0

Android 13 agregó compatibilidad para conectarse a dispositivos MIDI 2.0 a través de USB, que se comunican con paquetes MIDI universales (UMP). Android 15 extiende la compatibilidad con UMP a las apps de MIDI virtual, lo que permite que las apps de composición controlen las apps de sintetizador como un dispositivo MIDI 2.0 virtual, al igual que lo harían con un dispositivo MIDI 2.0 USB.

Decodificación de software AV1 más eficiente

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.

Productividad y herramientas para desarrolladores

Si bien la mayor parte de nuestro trabajo para mejorar la productividad se centra en herramientas como Android Studio, Jetpack Compose y las bibliotecas de Android Jetpack, siempre buscamos formas en la plataforma que te ayuden a hacer realidad tu visión con mayor facilidad.

Actualizaciones de 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 and strictmath methods
• util package updates including sequenced collection, map, and set
• ByteBuffer support in Deflater
• 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.

Mejoras en los archivos 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.

Mejoras en el cambio automático de idioma

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.

Se mejoró la API de 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:

val newTypeface = Typeface.CustomFallbackBuilder(
            FontFamily.Builder(
                Font.Builder(assets, "RobotoFlex.ttf").build())
                    .buildVariableFamily())
    .build()

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:

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()

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:

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.

Controles detallados de salto de línea

Starting in Android 15, a TextView and the underlying line breaker can preserve the given portion of text in the same line to improve readability. You can take advantage of this line break customization by using the <nobreak> tag in string resources or createNoBreakSpan. Similarly, you can preserve words from hyphenation by using the <nohyphen> tag or createNoHyphenationSpan.

For example, the following string resource doesn't include a line break, and renders with the text "Pixel 8 Pro." breaking in an undesirable place:

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

In contrast, this string resource includes the <nobreak> tag, which wraps the phrase "Pixel 8 Pro." and prevents line breaks:

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

The difference in how these strings are rendered is shown in the following images:

Layout for a line of text where the phrase "Pixel 8 Pro." isn't wrapped using a <nobreak> tag.

Layout for the same line of text where the phrase "Pixel 8 Pro." is wrapped using a <nobreak> tag.

Archivo de apps

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.

Gráficos

Android 15 ofrece las mejoras de gráficos más recientes, como ANGLE y adiciones al sistema de gráficos Canvas.

Modernización del acceso a las GPU de Android

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++.

Mejoras de Canvas

Android 15 continúa nuestra modernización del sistema de gráficos Canvas de Android con capacidades nuevas:

• Matrix44 proporciona una matriz de 4 × 4 para transformar las coordenadas que se deben usar cuando desees manipular el lienzo en 3D.
• clipShader realiza una intersección entre el clip actual y el sombreador especificado, mientras que clipOutShader establece el clip según la diferencia entre el clip actual y el sombreador, y cada uno trata al sombreador como una máscara alfa. Esto permite dibujar formas complejas de manera eficiente.

Rendimiento y batería

Android continúa su enfoque en ayudarte a mejorar el rendimiento y la calidad de tus apps. Android 15 presenta nuevas APIs que ayudan a que las tareas de tu app sean más eficientes de ejecutar, optimizar el rendimiento de las apps y recopilar estadísticas sobre ellas.

Si deseas conocer las prácticas recomendadas para ahorrar batería, depurar el uso de la red y la energía, y obtener detalles sobre cómo mejoramos la eficiencia de la batería del trabajo en segundo plano en Android 15 y versiones recientes de Android, consulta el artículo de Google I/O Cómo mejorar la eficiencia de la batería del trabajo en segundo plano en Android.

API de ApplicationStartInfo

In previous versions of Android, app startup has been a bit of a mystery. It was challenging to determine within your app whether it started from a cold, warm, or hot state. It was also difficult to know how long your app spent during the various launch phases: forking the process, calling onCreate, drawing the first frame, and more. When your Application class was instantiated, you had no way of knowing whether the app started from a broadcast, a content provider, a job, a backup, boot complete, an alarm, or an Activity.

The ApplicationStartInfo API on Android 15 provides all of this and more. You can even choose to add your own timestamps into the flow to help collect timing data in one place. In addition to collecting metrics, you can use ApplicationStartInfo to help directly optimize app startup; for example, you can eliminate the costly instantiation of UI-related libraries within your Application class when your app is starting up due to a broadcast.

Información detallada sobre el tamaño de la app

Since Android 8.0 (API level 26), Android has included the StorageStats.getAppBytes API that summarizes the installed size of an app as a single number of bytes, which is a sum of the APK size, the size of files extracted from the APK, and files that were generated on the device such as ahead-of-time (AOT) compiled code. This number is not very insightful in terms of how your app is using storage.

Android 15 adds the StorageStats.getAppBytesByDataType([type]) API, which lets you get insight into how your app is using up all that space, including APK file splits, AOT and speedup related code, dex metadata, libraries, and guided profiles.

Generación de perfiles administrada por la app

Android 15 incluye la clase ProfilingManager, que te permite recopilar información de generación de perfiles desde tu app. Pensamos finalizar con una API de Android Jetpack que simplificará la construcción de perfiles pero la API principal permitirá la recolección de volcados de montón, perfiles, muestreo de pila y mucho más. Proporciona una devolución de llamada a tu app con un etiqueta proporcionada para identificar el archivo de salida, que se entrega a los archivos de tu app . La API aplica un límite de frecuencia para minimizar el impacto en el rendimiento.

Mejoras en la base de datos SQLite

Android 15 presenta las APIs de SQLite que exponen funciones avanzadas del un motor SQLite subyacente que se dirija a problemas de rendimiento específicos que pueden en las apps. Estas APIs se incluyen con la actualización de SQLite a la versión 3.44.3

Los desarrolladores deben consultar las prácticas recomendadas para el rendimiento de SQLite para aprovechar al máximo su base de datos, en especial cuando trabajan con bases de datos grandes o cuando ejecutan consultas sensibles a la latencia.

• Transacciones diferidas de solo lectura: Cuando emitas transacciones de solo lectura (no incluyas instrucciones de escritura), usa beginTransactionReadOnly() y beginTransactionWithListenerReadOnly(SQLiteTransactionListener) para emitir transacciones DEFERRED de solo lectura. Estas transacciones se pueden ejecutar de forma simultánea entre sí y, si la base de datos está en modo WAL, se pueden ejecutar de forma simultánea con transacciones IMMEDIATE o EXCLUSIVE.
• Recuento y IDs de filas: Se agregaron APIs para recuperar el recuento de filas modificadas o el ID de la última fila insertada sin emitir una consulta adicional. getLastChangedRowCount() muestra la cantidad de filas que se insertaron, actualizaron o borraron mediante la instrucción de SQL más reciente en la transacción actual, mientras que getTotalChangedRowCount() devuelve el recuento de la conexión actual. getLastInsertRowId() muestra el rowid de la última fila que se insertará en la conexión actual.
• Sentencias sin procesar: Emite una sentencia SQlite sin procesar, omitiendo los wrappers de conveniencia y cualquier sobrecarga de procesamiento adicional que puedan generar.

Actualizaciones del framework de rendimiento dinámico de Android

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.

Privacidad

Android 15 incluye una variedad de funciones que ayudan a los desarrolladores de apps a proteger la privacidad del usuario.

Detección de grabación de pantalla

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)
}

Capacidades expandidas de IntentFilter

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>
  <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:domain="astore.com" />
  <uri-relative-filter-group>
    <data android:pathPrefix="/auth" />
    <data android:query="region=na" />
  </uri-relative-filter-group>
  <uri-relative-filter-group android:allow="false">
    <data android:pathPrefix="/auth" />
    <data android:query="mobileoptout=true" />
  </uri-relative-filter-group>
  <uri-relative-filter-group android:allow="false">
    <data android:pathPrefix="/auth" />
    <data android:fragmentPrefix="faq" />
  </uri-relative-filter-group>
</intent-filter>

Espacio privado

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:

• Apps with logic for work profiles that assumes that any installed copies of their app that aren't in the main profile are in the work profile.
• Medical apps
• Launcher apps
• App store apps

Consultar la selección más reciente del usuario para el acceso a las fotos seleccionadas

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.

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()
   )
)

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

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

Skin temperature tracking allows users to store and share more accurate temperature data from a wearable or other tracking device.

Training plans are structured workout plans to help a user achieve their fitness goals. Training plans support includes a variety of completion and performance goals:

• Completion goals around calories burned, distance, duration, repetition, and steps.
• Performance goals around as many repetitions as possible (AMRAP), cadence, heart rate, power, perceived rate of exertion, and speed.

Learn more about the latest updates to Health Connect in Android in the Building adaptable experiences with Android Health talk from Google I/O.

Compartir pantalla parcialmente

Android 15 supports partial 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 partial screen sharing experience. Note that for apps targeting Android 14 (API level 34) or higher, user consent is required for each MediaProjection capture session.

IU del sistema y experiencia del usuario

Android 15 ofrece a los desarrolladores y usuarios de apps más control y flexibilidad para configurar sus dispositivos en función de sus necesidades.

Vistas previas de widgets más completas con la API de Generated Previews

Antes de Android 15, la única forma de proporcionar vistas previas del selector de widgets era especificar un recurso de imagen o diseño estático. Estas vistas previas suelen diferir significativamente del aspecto del widget real cuando se coloca en la pantalla principal. Además, no se pueden crear recursos estáticos con Jetpack Glance, por lo que un vistazo desarrollador tuvo que hacer una captura de pantalla de su widget o crear un diseño XML para tener una vista previa del widget.

Android 15 agrega compatibilidad con vistas previas generadas. Esto significa que el widget de la app los proveedores pueden generar RemoteViews para usar como vista previa del selector, en lugar de un recurso estático.

API de Push

Las apps pueden proporcionar vistas previas generadas a través de una API de push. Las apps pueden proporcionar vistas previas en cualquier momento de su ciclo de vida y no reciben una solicitud explícita del host para proporcionarlas. Las vistas previas se conservan en AppWidgetService, y los hosts pueden solicitarlas a pedido. En el siguiente ejemplo, se carga un recurso de diseño de widget XML y se establece como la vista previa:

AppWidgetManager.getInstance(appContext).setWidgetPreview(
   ComponentName(
       appContext,
       SociaLiteAppWidgetReceiver::class.java
   ),
   AppWidgetProviderInfo.WIDGET_CATEGORY_HOME_SCREEN,
   RemoteViews("com.example", R.layout.widget_preview)
)

El flujo esperado es el siguiente:

1. En cualquier momento, el proveedor de widgets llama a setWidgetPreview. El valor proporcionado las vistas previas se conservan en AppWidgetService con otra información del proveedor
2. setWidgetPreview notifica a los hosts una vista previa actualizada a través de la devolución de llamada AppWidgetHost.onProvidersChanged. En respuesta, el host del widget vuelve a cargar toda la información del proveedor.
3. Cuando se muestra una vista previa del widget, el host verifica AppWidgetProviderInfo.generatedPreviewCategories y si el elemento elegido categoría está disponible, llama a AppWidgetManager.getWidgetPreview para mostrar la vista previa guardada para este proveedor.

Cuándo llamar a setWidgetPreview

Debido a que no hay devolución de llamada para proporcionar vistas previas, las apps pueden optar por enviar vistas previas en cualquier momento mientras se están ejecutando. La frecuencia con la que se actualiza la vista previa depende del caso de uso del widget.

En la siguiente lista, se describen las dos categorías principales de casos de uso de vista previa:

• Los proveedores que muestran datos reales en las vistas previas de sus widgets, como los o información reciente. Estos proveedores pueden configurar la vista previa una vez que el usuario accede o realiza la configuración inicial en su app. Después de esto, pueden configurar una tarea periódica para actualizar las vistas previas en la cadencia que elijan. Algunos ejemplos de este tipo de widget son los de fotos, calendario, clima o noticias.
• Proveedores que muestran información estática en vistas previas o widgets de acción rápida que no muestran ningún dato. Estos proveedores pueden establecer vistas previas una vez, cuando se inicia la app por primera vez. Algunos ejemplos de este tipo de widget son el widget de acciones rápidas de Drive o el widget de accesos directos de Chrome.

Algunos proveedores pueden mostrar vistas previas estáticas en el selector del modo Hub información del selector de la pantalla principal. Estos proveedores deben seguir las instrucciones para ambos casos de uso para configurar las vistas previas.

Pantalla en pantalla

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.

Mejora de las reglas de No interrumpir

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.

Cómo establecer VibrationEffect para los canales de notificaciones

Android 15 admite la configuración de vibraciones enriquecidas para las notificaciones entrantes canal con NotificationChannel.setVibrationEffect, por lo que los usuarios pueden distinguir entre distintos tipos de notificaciones tener que mirar su dispositivo.

Pantallas y factores de forma grandes

Android 15 brinda a tus apps la compatibilidad para aprovechar al máximo los factores de forma de Android, incluidas las pantallas grandes, los dispositivos plegables y los dispositivos plegables.

Mejora de la realización de varias tareas a la vez en pantalla grande

Android 15 gives users better ways to multitask on large screen devices. For example, users can save their favorite split-screen app combinations for quick access and pin the taskbar on screen to quickly switch between apps. This means that making sure your app is adaptive is more important than ever.

Google I/O has sessions on Building adaptive Android apps and Building UI with the Material 3 adaptive library that can help, and our documentation has more to help you Design for large screens.

Compatibilidad con pantallas de portada

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.

Conectividad

Android 15 actualiza la plataforma para que tu app pueda acceder a los avances más recientes en tecnologías inalámbricas y de comunicación.

Compatibilidad con satélites

Android 15 continúa ampliando la compatibilidad de la plataforma con la conectividad satelital y, además, incluye algunos elementos de la IU para garantizar una experiencia del usuario coherente en todo el panorama de conectividad satelital.

Las apps pueden usar ServiceState.isUsingNonTerrestrialNetwork() para detectar cuándo un dispositivo está conectado a un satélite, lo que les permite saber por qué es posible que los servicios de red completos no estén disponibles. Además, Android 15 admite apps de SMS y MMS, así como apps de RCS precargadas para usar conectividad satelital para enviar y recibir mensajes.

Experiencias NFC más fluidas

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.

Rol de Billetera

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.

Seguridad

Android 15 te ayuda a mejorar la seguridad de tu app, proteger sus datos y les brinda a los usuarios más transparencia y control sobre sus datos. Consulta la charla Cómo proteger la seguridad del usuario en Android de Google I/O si deseas obtener más información sobre lo que hacemos para mejorar la protección de los usuarios y proteger tu app contra nuevas amenazas.

Cómo integrar Credential Manager con la función Autocompletar

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.

Integra el registro y el acceso con un solo toque con instrucciones biométricas

El Administrador de credenciales integra mensajes biométricos en la creación de credenciales. y procesos de acceso, lo que elimina la necesidad de que los proveedores gestionen instrucciones biométricas. Como resultado, los proveedores de credenciales solo deben enfocarse en los resultados de los flujos de creación y obtención, junto con el resultado del flujo biométrico. Este proceso simplificado crea una credencial más eficiente y optimizada de creación y recuperación.

Administración de claves para la encriptación de extremo a extremo

Presentamos E2eeContactKeysManager en Android 15, que facilita la encriptación de extremo a extremo (E2EE) en tus apps para Android mediante una API a nivel del SO destinada al almacenamiento de claves públicas criptográficas.

El E2eeContactKeysManager está diseñado para integrarse con la app de contactos de la plataforma a fin de brindarles a los usuarios una forma centralizada de administrar y verificar las claves públicas de sus contactos.

Comprobaciones de permisos en URI de contenido

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

• Context.checkContentUriPermissionFull: This performs a full permission check on content URIs.
• Activity manifest attribute requireContentUriPermissionFromCaller: This enforces specified permissions on the provided content URIs at activity launch.
• ComponentCaller class for Activity callers: This represents the app that launched the activity.

Accesibilidad

En Android 15, se agregan funciones que mejoran la accesibilidad para los usuarios.

Mejor braille

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.

Internacionalización

En Android 15, se agregan funciones y capacidades que complementan la experiencia del usuario cuando un dispositivo se usa en diferentes idiomas.

Fuente 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.

Justificación entre caracteres

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.

Layout for Japanese text using JUSTIFICATION_MODE_NONE.

Layout for English text using JUSTIFICATION_MODE_NONE.

Layout for Japanese text using JUSTIFICATION_MODE_INTER_WORD.

Layout for English text using JUSTIFICATION_MODE_INTER_WORD.

Layout for Japanese text using the JUSTIFICATION_MODE_INTER_CHARACTER.

Layout for English text using the JUSTIFICATION_MODE_INTER_CHARACTER.

Configuración de salto de línea automático

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 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:

Nueva fuente japonesa hentaigana

In Android 15, a font file for old Japanese Hiragana (known as Hentaigana) is bundled by default. The unique shapes of Hentaigana characters can add a distinctive flair to artwork or design while also helping to preserve accurate transmission and understanding of ancient Japanese documents.
