O Android 15 introduz ótimos recursos e APIs para desenvolvedores. As seções a seguir resumem esses recursos para ajudar você a começar a usar as APIs relacionadas.
Para uma lista detalhada das APIs adicionadas, modificadas e removidas, leia o Relatório de diferenças da API. Para detalhes sobre as APIs adicionadas, acesse a Referência da API do Android. Para o Android 15, procure APIs que foram adicionadas no nível 35 da API. Para saber mais sobre as áreas em que as mudanças na plataforma podem afetar seus apps, confira as mudanças de comportamento do Android 15 para apps destinados ao Android 15 e para todos os apps.
Câmera e mídia
O Android 15 inclui vários recursos que melhoram a experiência de mídia e câmera e dão acesso a ferramentas e hardware para ajudar os criadores de conteúdo a dar vida à visão deles no Android.
Para saber mais sobre os recursos e as soluções para desenvolvedores mais recentes de mídia e câmera do Android, assista à palestra Como criar experiências modernas de mídia e câmera no Android do Google I/O.
Aumento do modo pouca 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 da câmera no 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
andTORCH
modes while capturing images.
Controle de headroom de HDR
O Android 15 escolhe o headroom HDR apropriado para os recursos do dispositivo
e a profundidade de bits do painel. Para páginas com muito conteúdo
SDR, como um app de mensagens que mostra uma única miniatura HDR, esse
comportamento pode acabar influenciando negativamente o brilho percebido do conteúdo
SDR. O Android 15 permite controlar o headroom HDR com
setDesiredHdrHeadroom
para encontrar um equilíbrio entre conteúdo SDR
e HDR.

Controle de intensidade
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 2.0 virtuais
O Android 13 adicionou suporte à conexão com dispositivos MIDI 2.0 usando USB, que se comunicam usando pacotes MIDI universais (UMPs). O Android 15 estende o suporte de UMP a apps MIDI virtuais, permitindo que apps de composição controlem apps de sintetizador como um dispositivo MIDI 2.0 virtual, assim como fariam com um dispositivo USB MIDI 2.0.
Decodificação de software AV1 mais eficiente
dav1d, o popular decodificador de software AV1 da VideoLAN, está disponível para dispositivos Android que não oferecem suporte à decodificação AV1 em hardware. O dav1d tem até três vezes mais desempenho do que o decodificador de software AV1 herdado, permitindo a reprodução de AV1 em alta definição para mais usuários, incluindo alguns dispositivos de nível baixo e médio.
O app precisa ativar o uso do dav1d invocando-o pelo nome
"c2.android.av1-dav1d.decoder"
. O dav1d vai se tornar o decodificador de software AV1
padrão em uma atualização subsequente. Esse suporte é padronizado e tem backport para
dispositivos Android 11 que recebem atualizações do sistema do Google Play.
Produtividade e ferramentas para desenvolvedores
Embora a maior parte do nosso trabalho para melhorar sua produtividade se concentre em ferramentas como o Android Studio, o Jetpack Compose e as bibliotecas do Android Jetpack, sempre buscamos maneiras na plataforma para ajudar você a realizar sua visão com mais facilidade.
Atualizações do 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.
Melhorias no 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
.
Refinamentos na troca automática 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.
API OpenType Variable Font aprimorada
O Android 15 melhora a usabilidade da fonte variável OpenType. É possível criar
uma instância FontFamily
de uma fonte variável sem especificar os eixos de peso
com a API buildVariableFamily
. O renderizador de texto substitui o valor
do eixo wght
para corresponder ao texto exibido.
O uso da API simplifica o código para criar uma Typeface
consideravelmente:
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();
Antes, para criar o mesmo Typeface
, era necessário muito mais código:
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();
Confira um exemplo de como uma Typeface
foi criada com a API antiga e a nova.
renderiza:
Neste exemplo, a Typeface
criada com a API antiga não tem a
para criar pesos de fonte precisos para os tamanhos 350, 450, 550 e 650
instâncias de Font
, então o renderizador retorna ao peso mais próximo. Portanto,
neste caso, 300 é renderizado em vez de 350, 400 é renderizado em vez de 450 e
assim por diante. Por outro lado, o Typeface
criado com as novas APIs cria dinamicamente
uma instância Font
para um determinado peso. Assim, pesos precisos são renderizados para 350,
450, 550 e 650.
Controles granulares de quebra de linha
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:

<nobreak>
tag.
<nobreak>
tag.Arquivamento 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.
Ativar o modo de 16 KB em um dispositivo usando as opções do desenvolvedor

Ative a opção de desenvolvedor Inicializar com tamanho de página de 16 KB para inicializar um dispositivo no modo de 16 KB.
A partir do Android 15 QPR1, é possível usar a opção do desenvolvedor disponível em alguns dispositivos para inicializar o aparelho no modo de 16 KB e realizar testes no dispositivo. Antes de usar a opção do desenvolvedor, acesse Configurações > Sistema > Atualizações de software e aplique as atualizações disponíveis.
Essa opção de desenvolvedor está disponível nos seguintes dispositivos:

Pixel 8a (com Android 15 QPR1 ou mais recente)
Pixel 9, 9 Pro e 9 Pro XL (com Android 15 QPR2 Beta 2 ou versões mais recentes)
Gráficos
O Android 15 traz as melhorias gráficas mais recentes, incluindo ANGLE e adições ao sistema de gráficos Canvas.
Modernização do acesso à GPU do Android
O hardware do Android evoluiu bastante desde os primeiros dias, quando o SO principal era executado em uma única CPU e as GPUs eram acessadas usando APIs baseadas em pipelines de função fixa. A API gráfica Vulkan® está disponível no NDK desde o Android 7.0 (nível 24 da API) com uma abstração de nível mais baixo que reflete melhor o hardware de GPU moderno, dimensiona melhor para oferecer suporte a vários núcleos de CPU e oferece uma sobrecarga reduzida do driver de CPU, o que resulta em um melhor desempenho do app. O Vulkan é compatível com todos os mecanismos de jogo modernos.
O Vulkan é a interface preferida do Android para a GPU. Portanto, o Android 15 inclui o ANGLE como uma camada opcional para executar o OpenGL® ES em cima do Vulkan. A mudança para o ANGLE padroniza a implementação do OpenGL do Android para melhorar a compatibilidade e, em alguns casos, o desempenho. Para testar a estabilidade e o desempenho do app OpenGL ES com o ANGLE, ative a opção do desenvolvedor em Configurações -> Sistema -> Opções do desenvolvedor -> Experimental: Ativar ANGLE no Android 15.
Planejamento do ANGLE no Vulkan para Android

Como parte do aperfeiçoamento da pilha de GPU, vamos enviar o ANGLE como o driver do sistema GL em mais dispositivos novos, com a expectativa de que o OpenGL/ES só estará disponível pelo ANGLE. No entanto, planejamos continuar oferecendo suporte ao OpenGL ES em todos os dispositivos.
Próximas etapas recomendadas
Use as opções para desenvolvedores para selecionar o driver ANGLE para OpenGL ES e testar seu app. Para novos projetos, recomendamos o uso do Vulkan para C/C++.
Melhorias no 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, whileclipOutShader
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.
Desempenho e bateria
O Android continua focado em ajudar você a melhorar a performance e a qualidade dos seus apps. O Android 15 apresenta APIs que ajudam a tornar as tarefas no seu app mais eficientes, otimizar a performance e coletar insights sobre seus apps.
Para conferir práticas recomendadas de eficiência da bateria, depurar o uso de rede e energia e detalhes sobre como estamos melhorando a eficiência da bateria do trabalho em segundo plano no Android 15 e em versões recentes do Android, assista à palestra Como melhorar a eficiência da bateria do trabalho em segundo plano no Android do Google I/O.
API ApplicationStartInfo
Nas versões anteriores do Android, a inicialização de apps era um pouco misteriosa. Era
difícil determinar no app se ele foi iniciado a partir de um estado frio, quente
ou aquecido. Também era difícil saber quanto tempo o app levava durante as
várias fases de inicialização: bifurcar o processo, chamar onCreate
, desenhar o
primeiro frame e muito mais. Quando a classe Application
foi instanciada, você não tinha
como saber se o app foi iniciado por uma transmissão, um provedor de conteúdo, um
job, um backup, a inicialização completa, um alarme ou um Activity
.
A API ApplicationStartInfo
no Android 15 oferece
tudo isso e muito mais. Você pode até adicionar seus próprios carimbos de data/hora ao fluxo para ajudar a coletar dados de tempo em um só lugar. Além de coletar
métricas, você pode usar ApplicationStartInfo
para ajudar a otimizar diretamente a inicialização
do app. Por exemplo, é possível eliminar a instanciação cara de bibliotecas relacionadas à
interface na classe Application
quando o app está sendo inicializado devido a uma
transmissão.
Informações detalhadas sobre o tamanho do 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.
Criação de perfil gerenciada pelo app
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.
Melhorias no banco de dados 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()
andbeginTransactionWithListenerReadOnly(SQLiteTransactionListener)
to issue read-onlyDEFERRED
transactions. Such transactions can run concurrently with each other, and if the database is in WAL mode, they can run concurrently withIMMEDIATE
orEXCLUSIVE
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, whilegetTotalChangedRowCount()
returns the count on the current connection.getLastInsertRowId()
returns therowid
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.
Atualizações do Android Dynamic Performance Framework
O Android 15 continua nosso investimento no Android Dynamic Performance Framework (ADPF), um conjunto de APIs que permite que jogos e apps de alta performance interajam mais diretamente com os sistemas térmicos e de energia de dispositivos Android. Em dispositivos com suporte, o Android 15 adiciona recursos ADPF:
- Um modo de economia de energia para sessões de dicas para indicar que as linhas de execução associadas devem preferir a economia de energia em vez de desempenho, ótimo para cargas de trabalho em segundo plano de longa duração.
- As durações de trabalho da GPU e da CPU podem ser relatadas em sessões de dicas, permitindo que o sistema ajuste as frequências da CPU e da GPU juntos para atender melhor às demandas de carga de trabalho.
- Limites de margem térmica para interpretar possíveis status de limitação térmica com base na previsão de margem.
Para saber mais sobre como usar o ADPF em apps e jogos, consulte a documentação.
Privacidade
O Android 15 inclui vários recursos que ajudam os desenvolvedores de apps a proteger a privacidade dos usuários.
Detecção de gravação de tela
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)
}
Recursos expandidos do 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 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>
<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>
Espaço 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 a seleção de usuário mais recente para o acesso a fotos selecionadas
Agora os apps podem destacar apenas as fotos e os vídeos selecionados mais recentemente quando
acesso parcial às permissões de mídia é concedido. Esse recurso pode melhorar
a experiência do usuário em apps que solicitam acesso frequente a fotos e
vídeos. Para usar esse recurso no app, ative o
Argumento QUERY_ARG_LATEST_SELECTION_ONLY
ao consultar MediaStore
usando 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) });
Sandbox de privacidade no Android
Android 15 includes the latest Android Ad Services extensions, incorporating the latest version of the Privacy Sandbox on Android. This addition is part of our work to develop technologies that improve user privacy and enable effective, personalized advertising experiences for mobile apps. Our privacy sandbox page has more information about the Privacy Sandbox on Android developer preview and beta programs to help you get started.
Conexão Saúde
Android 15 integrates the latest extensions around Health Connect by Android, a secure and centralized platform to manage and share app-collected health and fitness data. This update adds support for additional data types across fitness, nutrition, skin temperature, training plans, and more.
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.
Compartilhamento de tela de app
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.
Experiência do usuário e interface do sistema
O Android 15 oferece aos desenvolvedores de apps e usuários mais controle e flexibilidade para configurar o dispositivo de acordo com as necessidades.
Para saber mais sobre como usar as melhorias mais recentes do Android 15 para melhorar a experiência do usuário do seu app, assista à palestra Melhorar a experiência do usuário do seu app Android no Google I/O.
Prévia de widgets mais completa com a 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.

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.
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.
Regras do modo "Não perturbe" aprimoradas
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 toAutomaticZenRule
that describes the conditions on which the rule should become active for the user. - Added
ZenDeviceEffects
toAutomaticZenRule
, allowing rules to trigger things like grayscale display, night mode, or dimming the wallpaper.
Definir VibrationEffect para canais de notificação
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 da barra de status de projeção de mídia e parada automática
Media projection can expose private user information. A new, prominent status bar chip makes users aware of any ongoing screen projection. Users can tap the chip to stop screen casting, sharing, or recording. Also, for a more intuitive user experience, any in‑progress screen projection now automatically stops when the device screen is locked.

Telas grandes e formatos
O Android 15 oferece aos seus apps o suporte necessário para aproveitar ao máximo os formatos do Android, incluindo telas grandes, dispositivos dobráveis e flip.
Mais facilidade para várias tarefas em telas grandes
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.
Suporte à tela de capa
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.
Conectividade
O Android 15 atualiza a plataforma para dar ao seu app acesso aos avanços mais recentes em tecnologias de comunicação e sem fio.
Suporte a satélite
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.

Experiências de NFC mais 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.
Função da carteira
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.
Segurança
O Android 15 ajuda a melhorar a segurança do app, proteger os dados dele e oferece aos usuários mais transparência e controle sobre os dados. Assista à palestra Proteção da segurança do usuário no Android (em inglês) do Google I/O para saber mais sobre o que estamos fazendo para melhorar as proteções do usuário e proteger seu app contra novas ameaças.
Integrar o Gerenciador de credenciais ao preenchimento automático
A partir do Android 15, os desenvolvedores podem vincular visualizações específicas, como campos de nome de usuário ou senha, a solicitações do Gerenciador de credenciais, facilitando a criação de uma experiência personalizada do usuário durante o processo de login. Quando o usuário foca em uma dessas visualizações, uma solicitação correspondente é enviada ao Gerenciador de credenciais. As credenciais resultantes são agregadas entre os provedores e exibidas em interfaces padrão de preenchimento automático, como sugestões inline ou suspensas. A biblioteca androidx.credentials do Jetpack é o endpoint preferencial para desenvolvedores e em breve estará disponível para aprimorar ainda mais esse recurso no Android 15 e versões mais recentes.
Integrar o processo de login e inscrição com um único toque às solicitações biométricas
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.
Gerenciamento de chaves para criptografia de ponta a ponta
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.
Verificações de permissão em URIs de conteúdo
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 attributerequireContentUriPermissionFromCaller
: This enforces specified permissions on the provided content URIs at activity launch.ComponentCaller
class forActivity
callers: This represents the app that launched the activity.
Acessibilidade
O Android 15 adiciona recursos que melhoram a acessibilidade para os usuários.
Melhorias no 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.
Internacionalização
O Android 15 adiciona recursos e funcionalidades que complementam a experiência do usuário quando um dispositivo é usado em diferentes idiomas.
Fonte variável CJK
A partir do Android 15, o arquivo de fonte para idiomas chinês, japonês e coreano (CJK), NotoSansCJK, agora é uma fonte variável. As fontes variáveis oferecem possibilidades de tipografia criativa em idiomas CJK. Os designers podem explorar uma gama mais ampla de estilos e criar layouts visualmente atraentes que antes eram difíceis ou impossíveis de alcançar.

Justificação entre caracteres
No Android 15 e versões mais recentes, o texto pode ser justificado usando o espaçamento entre letras
usando JUSTIFICATION_MODE_INTER_CHARACTER
. A justificação entre palavras foi
introduzida pela primeira vez no Android 8.0 (nível 26 da API), e a justificação
entre caracteres oferece recursos semelhantes para idiomas que usam o
caractere de espaço em branco para segmentação, como chinês, japonês e outros.

.Configuração automática de quebra de linha
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.
This is the same as applying
LINE_BREAK_WORD_STYLE_NONE
.Fonte Hentaigana japonesa adicional
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.
