Mudanças de comportamento: apps destinados ao Android 15 ou versões mais recentes

Como as versões anteriores, o Android 15 inclui mudanças de comportamento que podem afetar seu app. As mudanças de comportamento a seguir se aplicam exclusivamente a apps direcionados ao Android 15 ou versões mais recentes. Caso seu app seja direcionado ao Android 15 ou a versões mais recentes, modifique seu app para oferecer suporte a esses comportamentos de forma adequada, em que aplicável.

Consulte também a lista de mudanças de comportamento que afetam todos os apps. executados no Android 15, independente do targetSdkVersion do app.

Principal recurso

O Android 15 modifica ou expande vários recursos principais do sistema Android.

Mudanças nos serviços em primeiro plano

We are making the following changes to foreground services with Android 15.

• Data sync foreground service timeout behavior
• New media processing foreground service type
• Restrictions on BOOT_COMPLETED broadcast receivers launching foreground services
• Restrictions on starting foreground services while an app holds the SYSTEM_ALERT_WINDOW permission

Data sync foreground service timeout behavior

Android 15 introduces a new timeout behavior to dataSync for apps targeting Android 15 (API level 35) or higher. This behavior also applies to the new mediaProcessing foreground service type.

The system permits an app's dataSync services to run for a total of 6 hours in a 24-hour period, after which the system calls the running service's Service.onTimeout(int, int) method (introduced in Android 15). At this time, the service has a few seconds to call Service.stopSelf(). When Service.onTimeout() is called, the service is no longer considered a foreground service. If the service does not call Service.stopSelf(), the system throws an internal exception. The exception is logged in Logcat with the following message:

Fatal Exception: android.app.RemoteServiceException: "A foreground service of
type dataSync did not stop within its timeout: [component name]"

To avoid problems with this behavior change, you can do one or more of the following:

1. Have your service implement the new Service.onTimeout(int, int) method. When your app receives the callback, make sure to call stopSelf() within a few seconds. (If you don't stop the app right away, the system generates a failure.)
2. Make sure your app's dataSync services don't run for more than a total of 6 hours in any 24-hour period (unless the user interacts with the app, resetting the timer).
3. Only start dataSync foreground services as a result of direct user interaction; since your app is in the foreground when the service starts, your service has the full six hours after the app goes to the background.
4. Instead of using a dataSync foreground service, use an alternative API.

If your app's dataSync foreground services have run for 6 hours in the last 24, you cannot start another dataSync foreground service unless the user has brought your app to the foreground (which resets the timer). If you try to start another dataSync foreground service, the system throws ForegroundServiceStartNotAllowedException with an error message like "Time limit already exhausted for foreground service type dataSync".

Testing

To test your app's behavior, you can enable data sync timeouts even if your app is not targeting Android 15 (as long as the app is running on an Android 15 device). To enable timeouts, run the following adb command:

adb shell am compat enable FGS_INTRODUCE_TIME_LIMITS your-package-name

You can also adjust the timeout period, to make it easier to test how your app behaves when the limit is reached. To set a new timeout period, run the following adb command:

adb shell device_config put activity_manager data_sync_fgs_timeout_duration duration-in-milliseconds

New media processing foreground service type

Android 15 introduces a new foreground service type, mediaProcessing. This service type is appropriate for operations like transcoding media files. For example, a media app might download an audio file and need to convert it to a different format before playing it. You can use a mediaProcessing foreground service to make sure the conversion continues even while the app is in the background.

The system permits an app's mediaProcessing services to run for a total of 6 hours in a 24-hour period, after which the system calls the running service's Service.onTimeout(int, int) method (introduced in Android 15). At this time, the service has a few seconds to call Service.stopSelf(). If the service does not call Service.stopSelf(), the system throws an internal exception. The exception is logged in Logcat with the following message:

Fatal Exception: android.app.RemoteServiceException: "A foreground service of
type mediaProcessing did not stop within its timeout: [component name]"

To avoid having the exception, you can do one of the following:

1. Have your service implement the new Service.onTimeout(int, int) method. When your app receives the callback, make sure to call stopSelf() within a few seconds. (If you don't stop the app right away, the system generates a failure.)
2. Make sure your app's mediaProcessing services don't run for more than a total of 6 hours in any 24-hour period (unless the user interacts with the app, resetting the timer).
3. Only start mediaProcessing foreground services as a result of direct user interaction; since your app is in the foreground when the service starts, your service has the full six hours after the app goes to the background.
4. Instead of using a mediaProcessing foreground service, use an alternative API, like WorkManager.

If your app's mediaProcessing foreground services have run for 6 hours in the last 24, you cannot start another mediaProcessing foreground service unless the user has brought your app to the foreground (which resets the timer). If you try to start another mediaProcessing foreground service, the system throws ForegroundServiceStartNotAllowedException with an error message like "Time limit already exhausted for foreground service type mediaProcessing".

For more information about the mediaProcessing service type, see Changes to foreground service types for Android 15: Media processing.

Testing

To test your app's behavior, you can enable media processing timeouts even if your app is not targeting Android 15 (as long as the app is running on an Android 15 device). To enable timeouts, run the following adb command:

adb shell am compat enable FGS_INTRODUCE_TIME_LIMITS your-package-name

You can also adjust the timeout period, to make it easier to test how your app behaves when the limit is reached. To set a new timeout period, run the following adb command:

adb shell device_config put activity_manager media_processing_fgs_timeout_duration duration-in-milliseconds

Restrictions on BOOT_COMPLETED broadcast receivers launching foreground services

There are new restrictions on BOOT_COMPLETED broadcast receivers launching foreground services. BOOT_COMPLETED receivers are not allowed to launch the following types of foreground services:

• dataSync
• camera
• mediaPlayback
• phoneCall
• mediaProjection
• microphone (this restriction has been in place for microphone since Android 14)

If a BOOT_COMPLETED receiver tries to launch any of those types of foreground services, the system throws ForegroundServiceStartNotAllowedException.

Testing

To test your app's behavior, you can enable these new restrictions even if your app is not targeting Android 15 (as long as the app is running on an Android 15 device). Run the following adb command:

adb shell am compat enable FGS_BOOT_COMPLETED_RESTRICTIONS your-package-name

To send a BOOT_COMPLETED broadcast without restarting the device, run the following adb command:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED your-package-name

Restrictions on starting foreground services while an app holds the SYSTEM_ALERT_WINDOW permission

Previously, if an app held the SYSTEM_ALERT_WINDOW permission, it could launch a foreground service even if the app was currently in the background (as discussed in exemptions from background start restrictions).

If an app targets Android 15, this exemption is now narrower. The app now needs to have the SYSTEM_ALERT_WINDOW permission and also have a visible overlay window. That is, the app needs to first launch a TYPE_APPLICATION_OVERLAY window and the window needs to be visible before you start a foreground service.

If your app attempts to start a foreground service from the background without meeting these new requirements (and it does not have some other exemption), the system throws ForegroundServiceStartNotAllowedException.

If your app declares the SYSTEM_ALERT_WINDOW permission and launches foreground services from the background, it may be affected by this change. If your app gets a ForegroundServiceStartNotAllowedException, check your app's order of operations and make sure your app already has an active overlay window before it attempts to start a foreground service from the background. You can check if your overlay window is currently visible by calling View.getWindowVisibility(), or you can override View.onWindowVisibilityChanged() to get notified whenever the visibility changes.

Testing

To test your app's behavior, you can enable these new restrictions even if your app is not targeting Android 15 (as long as the app is running on an Android 15 device). To enable these new restrictions on starting foreground services from the background, run the following adb command:

adb shell am compat enable FGS_SAW_RESTRICTIONS your-package-name

Mudanças na possibilidade de os apps modificarem o estado global do modo "Não perturbe"

Os apps direcionados ao Android 15 não podem mais mudar o estado ou a política global do Não perturbe em um dispositivo, seja modificando as configurações do usuário ou desativando o modo Não perturbe. Em vez disso, os apps precisam contribuir com um AutomaticZenRule, que o sistema combina em uma política global com o esquema most-restrictive-policy-wins atual. As chamadas para APIs existentes que anteriormente afetaram o estado global (setInterruptionFilter, setNotificationPolicy) resultam na criação ou atualização de um AutomaticZenRule implícito, que pode ser ativado e desativado dependendo do ciclo de chamadas dessas chamadas de API.

Essa mudança afeta apenas o comportamento observável se o app estiver chamando setInterruptionFilter(INTERRUPTION_FILTER_ALL) e espera que essa chamada desative um AutomaticZenRule que foi ativado anteriormente pelos proprietários.

Mudanças na API OpenJDK

O Android 15 continua o trabalho de atualizar as principais bibliotecas do Android para se alinhar com os recursos das versões mais recentes do LTS do OpenJDK.

Algumas dessas mudanças podem afetar a compatibilidade dos apps destinados à segmentação Android 15 (nível 35 da API):

• Mudanças nas APIs de formatação de strings: validação do índice de argumentos, flags A largura e a precisão agora são mais rigorosas com o uso das APIs String.format() e Formatter.format():

  • String.format(String, Object[])
  • String.format(Locale, String, Object[])
  • Formatter.format(String, Object[])
  • Formatter.format(Locale, String, Object[])

  Por exemplo, a exceção a seguir é gerada quando um índice de argumento de 0 é usado (%0 na string de formato):

  IllegalFormatArgumentIndexException: Illegal format argument index = 0
  

  Nesse caso, o problema pode ser corrigido usando um índice de argumento de 1 (%1). na string de formato).

• Mudanças no tipo de componente de Arrays.asList(...).toArray(): ao usar Arrays.asList(...).toArray(), o tipo de componente da matriz resultante é agora um Object, e não o tipo dos elementos da matriz. Então, o O código abaixo gera uma ClassCastException:

  String[] elements = (String[]) Arrays.asList("one", "two").toArray();
  

  Nesse caso, para preservar String como o tipo de componente no resultado pode usar Collection.toArray(Object[]):

  String[] elements = Arrays.asList("two", "one").toArray(new String[0]);
  

• Mudanças no processamento do código de linguagem: ao usar a API Locale, os códigos de idioma para hebraico, iídiche e indonésio não são mais convertidos às formas obsoletas (hebraico: iw, iídiche: ji e indonésio: in). Ao especificar o código do idioma para uma dessas localidades, use os códigos a partir da ISO 639-1 (hebraico: he, iídiche: yi e indonésio: id).

• Mudanças em sequências int aleatórias: após as alterações feitas em https://bugs.openjdk.org/Browse/JDK-8301574, o seguinte Métodos Random.ints() agora retornam uma sequência de números diferente da os métodos Random.nextInt() fazem:

  • Random.ints(long)
  • Random.ints(long, int, int)
  • Random.ints(int, int)
  • Random.ints()

  De modo geral, essa mudança não resulta em um comportamento inapropriado para o app, mas seu o código não vai esperar que a sequência gerada pelos métodos Random.ints() corresponder a Random.nextInt().

A nova API SequencedCollection pode afetar a compatibilidade do seu app depois de atualizar compileSdk na configuração do build do app para usar Android 15 (nível 35 da API):

• Colisão com MutableList.removeFirst() e Funções de extensão MutableList.removeLast() em kotlin-stdlib

  O tipo List (link em inglês) em Java é mapeado para o tipo MutableList em Kotlin. Como as APIs List.removeFirst() e List.removeLast() foram lançados no Android 15 (nível 35 da API), o compilador Kotlin resolve chamadas de função, por exemplo, list.removeFirst(), estaticamente para a das novas APIs List em vez das funções de extensão kotlin-stdlib.

  Se um app for recompilado com compileSdk definido como 35 e minSdk definido como 34 ou anterior, e o app é executado no Android 14 e em versões anteriores, um ambiente de execução. é gerado:

  java.lang.NoSuchMethodError: No virtual method
  removeFirst()Ljava/lang/Object; in class Ljava/util/ArrayList;
  

  A opção de lint NewApi já existente no Plug-in do Android para Gradle pode detectar esses erros novos usos de API.

  ./gradlew lint
  
  MainActivity.kt:41: Error: Call requires API level 35 (current min is 34): java.util.List#removeFirst [NewApi]
        list.removeFirst()
  

  Para corrigir a exceção de ambiente de execução e os erros de lint, removeFirst() e As chamadas de função removeLast() podem ser substituídas por removeAt(0) e removeAt(list.lastIndex), respectivamente, em Kotlin. Se você usa Android Studio Ladybug | versão 2024.1.3 ou mais recente, também fornece uma correção rápida para esses erros.

  Considere remover @SuppressLint("NewApi") e lintOptions { disable 'NewApi' } se a opção de lint tiver sido desativada.

• Colisão com outros métodos em Java

  Novos métodos foram adicionados aos tipos existentes, por exemplo, List e Deque. Esses novos métodos podem não ser compatíveis com métodos com o mesmo nome e tipos de argumento em outras interfaces e classes. No caso de uma colisão de assinatura de método com incompatibilidade, o compilador javac vai gerar um erro de tempo de build. Por exemplo:

  Exemplo de erro 1:

  javac MyList.java
  
  MyList.java:135: error: removeLast() in MyList cannot implement removeLast() in List
    public void removeLast() {
                ^
    return type void is not compatible with Object
    where E is a type-variable:
      E extends Object declared in interface List
  

  Exemplo de erro 2:

  javac MyList.java
  
  MyList.java:7: error: types Deque<Object> and List<Object> are incompatible;
  public class MyList implements  List<Object>, Deque<Object> {
    both define reversed(), but with unrelated return types
  1 error
  

  Exemplo de erro 3:

  javac MyList.java
  
  MyList.java:43: error: types List<E#1> and MyInterface<E#2> are incompatible;
  public static class MyList implements List<Object>, MyInterface<Object> {
    class MyList inherits unrelated defaults for getFirst() from types List and MyInterface
    where E#1,E#2 are type-variables:
      E#1 extends Object declared in interface List
      E#2 extends Object declared in interface MyInterface
  1 error
  

  Para corrigir esses erros de build, a classe que implementa essas interfaces deve substituir o método por um tipo de retorno compatível. Exemplo:

  @Override
  public Object getFirst() {
      return List.super.getLast();
  }
  

Segurança

O Android 15 inclui mudanças que promovem a segurança do sistema para ajudar a proteger os apps e os usuários contra apps maliciosos.

Inicializações de atividades seguras em segundo plano

Android 15 protects users from malicious apps and gives them more control over their devices by adding changes that prevent malicious background apps from bringing other apps to the foreground, elevating their privileges, and abusing user interaction. Background activity launches have been restricted since Android 10 (API level 29).

Other changes

In addition to the restriction for UID matching, these other changes are also included:

• Change PendingIntent creators to block background activity launches by default. This helps prevent apps from accidentally creating a PendingIntent that could be abused by malicious actors.
• Don't bring an app to the foreground unless the PendingIntent sender allows it. This change aims to prevent malicious apps from abusing the ability to start activities in the background. By default, apps are not allowed to bring the task stack to the foreground unless the creator allows background activity launch privileges or the sender has background activity launch privileges.
• Control how the top activity of a task stack can finish its task. If the top activity finishes a task, Android will go back to whichever task was last active. Moreover, if a non-top activity finishes its task, Android will go back to the home screen; it won't block the finish of this non-top activity.
• Prevent launching arbitrary activities from other apps into your own task. This change prevents malicious apps from phishing users by creating activities that appear to be from other apps.
• Block non-visible windows from being considered for background activity launches. This helps prevent malicious apps from abusing background activity launches to display unwanted or malicious content to users.

Intents mais seguras

Android 15 introduces new optional security measures to make intents safer and more robust. These changes are aimed at preventing potential vulnerabilities and misuse of intents that can be exploited by malicious apps. There are two main improvements to the security of intents in Android 15:

• Match target intent-filters: Intents that target specific components must accurately match the target's intent-filter specifications. If you send an intent to launch another app's activity, the target intent component needs to align with the receiving activity's declared intent-filters.
• Intents must have actions: Intents without an action will no longer match any intent-filters. This means that intents used to start activities or services must have a clearly defined action.

In order to check how your app responds to these changes, use StrictMode in your app. To see detailed logs about Intent usage violations, add the following method:

fun onCreate() {
    StrictMode.setVmPolicy(VmPolicy.Builder()
        .detectUnsafeIntentLaunch()
        .build()
    )
}

public void onCreate() {
    StrictMode.setVmPolicy(new VmPolicy.Builder()
            .detectUnsafeIntentLaunch()
            .build());
}

Experiência do usuário e interface do sistema

O Android 15 inclui algumas mudanças que visam criar uma versão mais consistente, experiência do usuário intuitiva.

Mudanças no encarte da janela

Há duas mudanças relacionadas a encartes de janela no Android 15: de ponta a ponta é aplicada por padrão, e também há mudanças de configuração, como a configuração padrão das barras do sistema.

Aplicação de ponta a ponta

Apps are edge-to-edge by default on devices running Android 15 if the app is targeting Android 15 (API level 35).

This is a breaking change that might negatively impact your app's UI. The changes affect the following UI areas:

• Gesture handle navigation bar
  • Transparent by default.
  • Bottom offset is disabled so content draws behind the system navigation bar unless insets are applied.
  • setNavigationBarColor and R.attr#navigationBarColor are deprecated and don't affect gesture navigation.
  • setNavigationBarContrastEnforced and R.attr#navigationBarContrastEnforced continue to have no effect on gesture navigation.
• 3-button navigation
  • Opacity set to 80% by default, with color possibly matching the window background.
  • Bottom offset disabled so content draws behind the system navigation bar unless insets are applied.
  • setNavigationBarColor and R.attr#navigationBarColor are set to match the window background by default. The window background must be a color drawable for this default to apply. This API is deprecated but continues to affect 3-button navigation.
  • setNavigationBarContrastEnforced and R.attr#navigationBarContrastEnforced is true by default, which adds an 80% opaque background across 3-button navigation.
• Status bar
  • Transparent by default.
  • The top offset is disabled so content draws behind the status bar unless insets are applied.
  • setStatusBarColor and R.attr#statusBarColor are deprecated and have no effect on Android 15.
  • setStatusBarContrastEnforced and R.attr#statusBarContrastEnforced are deprecated but still have an effect on Android 15.
• Display cutout
  • layoutInDisplayCutoutMode of non-floating windows must be LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS. SHORT_EDGES, NEVER, and DEFAULT are interpreted as ALWAYS so that users don't see a black bar caused by the display cutout and appear edge-to-edge.

The following example shows an app before and after targeting Android 15 (API level 35), and before and after applying insets.

What to check if your app is already edge-to-edge

If your app is already edge-to-edge and applies insets, you are mostly unimpacted, except in the following scenarios. However, even if you think you aren't impacted, we recommend you test your app.

• You have a non-floating window, such as an Activity that uses SHORT_EDGES, NEVER or DEFAULT instead of LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS. If your app crashes on launch, this might be due to your splashscreen. You can either upgrade the core splashscreen dependency to 1.2.0-alpha01 or later or set window.attributes.layoutInDisplayCutoutMode = WindowManager.LayoutInDisplayCutoutMode.always.
• There might be lower-traffic screens with occluded UI. Verify these less-visited screens don't have occluded UI. Lower-traffic screens include:
  • Onboarding or sign-in screens
  • Settings pages

What to check if your app is not already edge-to-edge

If your app is not already edge-to-edge, you are most likely impacted. In addition to the scenarios for apps that are already edge-to-edge, you should consider the following:

• If your app uses Material 3 Components ( androidx.compose.material3) in compose, such as TopAppBar, BottomAppBar, and NavigationBar, these components are likely not impacted because they automatically handle insets.
• If your app is using Material 2 Components ( androidx.compose.material) in Compose, these components don't automatically handle insets. However, you can get access to the insets and apply them manually. In androidx.compose.material 1.6.0 and later, use the windowInsets parameter to apply the insets manually for BottomAppBar, TopAppBar, BottomNavigation, and NavigationRail. Likewise, use the contentWindowInsets parameter for Scaffold.
• If your app uses views and Material Components (com.google.android.material), most views-based Material Components such as BottomNavigationView, BottomAppBar, NavigationRailView, or NavigationView, handle insets and require no additional work. However, you need to add android:fitsSystemWindows="true" if using AppBarLayout.
• For custom composables, apply the insets manually as padding. If your content is within a Scaffold, you can consume insets using the Scaffold padding values. Otherwise, apply padding using one of the WindowInsets.
• If your app is using views and BottomSheet, SideSheet or custom containers, apply padding using ViewCompat.setOnApplyWindowInsetsListener. For RecyclerView, apply padding using this listener and also add clipToPadding="false".

What to check if your app must offer custom background protection

If your app must offer custom background protection to 3-button navigation or the status bar, your app should place a composable or view behind the system bar using WindowInsets.Type#tappableElement() to get the 3-button navigation bar height or WindowInsets.Type#statusBars.

Additional edge-to-edge resources

See the Edge to Edge Views and Edge to Edge Compose guides for additional considerations on applying insets.

Deprecated APIs

The following APIs are now deprecated:

• R.attr#enforceStatusBarContrast
• R.attr#navigationBarColor
• R.attr#navigationBarDividerColor
• R.attr#statusBarColor
• Window#getNavigationBarColor
• Window#getNavigationBarDividerColor
• Window#getStatusBarColor
• Window#isStatusBarContrastEnforced
• Window#setDecorFitsSystemWindows
• Window#setNavigationBarColor
• Window#setNavigationBarDividerColor
• Window#setStatusBarColor
• Window#setStatusBarContrastEnforced

Configuração estável

If your app targets Android 15 (API level 35) or higher, Configuration no longer excludes the system bars. If you use the screen size in the Configuration class for layout calculation, you should replace it with better alternatives like an appropriate ViewGroup, WindowInsets, or WindowMetricsCalculator depending on your need.

Configuration has been available since API 1. It is typically obtained from Activity.onConfigurationChanged. It provides information like window density, orientation, and sizes. One important characteristic about the window sizes returned from Configuration is that it previously excluded the system bars.

The configuration size is typically used for resource selection, such as /res/layout-h500dp, and this is still a valid use case. However, using it for layout calculation has always been discouraged. If you do so, you should move away from it now. You should replace the use of Configuration with something more suitable depending on your use case.

If you use it to calculate the layout, use an appropriate ViewGroup, such as CoordinatorLayout or ConstraintLayout. If you use it to determine the height of the system navbar, use WindowInsets. If you want to know the current size of your app window, use computeCurrentWindowMetrics.

The following list describes the fields affected by this change:

• Configuration.screenWidthDp and screenHeightDp sizes no longer exclude the system bars.
• Configuration.smallestScreenWidthDp is indirectly affected by changes to screenWidthDp and screenHeightDp.
• Configuration.orientation is indirectly affected by changes to screenWidthDp and screenHeightDp on close-to-square devices.
• Display.getSize(Point) is indirectly affected by the changes in Configuration. This was deprecated beginning in API level 30.
• Display.getMetrics() has already worked like this since API level 33.

O atributo eleganteTextHeight assume o padrão como verdadeiro

For apps targeting Android 15 (API level 35), the elegantTextHeight TextView attribute becomes true by default, replacing the compact font used by default with some scripts that have large vertical metrics with one that is much more readable. The compact font was introduced to prevent breaking layouts; Android 13 (API level 33) prevents many of these breakages by allowing the text layout to stretch the vertical height utilizing the fallbackLineSpacing attribute.

In Android 15, the compact font still remains in the system, so your app can set elegantTextHeight to false to get the same behavior as before, but it is unlikely to be supported in upcoming releases. So, if your app supports the following scripts: Arabic, Lao, Myanmar, Tamil, Gujarati, Kannada, Malayalam, Odia, Telugu or Thai, test your app by setting elegantTextHeight to true.

Mudanças na largura da TextView em formas de letra complexas

In previous versions of Android, some cursive fonts or languages that have complex shaping might draw the letters in the previous or next character's area. In some cases, such letters were clipped at the beginning or ending position. Starting in Android 15, a TextView allocates width for drawing enough space for such letters and allows apps to request extra paddings to the left to prevent clipping.

Because this change affects how a TextView decides the width, TextView allocates more width by default if the app targets Android 15 (API level 35) or higher. You can enable or disable this behavior by calling the setUseBoundsForWidth API on TextView.

Because adding left padding might cause a misalignment for existing layouts, the padding is not added by default even for apps that target Android 15 or higher. However, you can add extra padding to preventing clipping by calling setShiftDrawingOffsetForStartOverhang.

The following examples show how these changes can improve text layout for some fonts and languages.

Standard layout for English text in a cursive font. Some of the letters are clipped. Here is the corresponding XML:

<TextView
    android:fontFamily="cursive"
    android:text="java" />

Layout for the same English text with additional width and padding. Here is the corresponding XML:

<TextView
    android:fontFamily="cursive"
    android:text="java"
    android:useBoundsForWidth="true"
    android:shiftDrawingOffsetForStartOverhang="true" />

Standard layout for Thai text. Some of the letters are clipped. Here is the corresponding XML:

<TextView
    android:text="คอมพิวเตอร์" />

Layout for the same Thai text with additional width and padding. Here is the corresponding XML:

<TextView
    android:text="คอมพิวเตอร์"
    android:useBoundsForWidth="true"
    android:shiftDrawingOffsetForStartOverhang="true" />

Altura da linha padrão com reconhecimento de localidade para EditText

In previous versions of Android, the text layout stretched the height of the text to meet the line height of the font that matched the current locale. For example, if the content was in Japanese, because the line height of the Japanese font is slightly larger than the one of a Latin font, the height of the text became slightly larger. However, despite these differences in line heights, the EditText element was sized uniformly, regardless of the locale being used, as illustrated in the following image:

For apps targeting Android 15 (API level 35), a minimum line height is now reserved for EditText to match the reference font for the specified Locale, as shown in the following image:

If needed, your app can restore the previous behavior by specifying the useLocalePreferredLineHeightForMinimum attribute to false, and your app can set custom minimum vertical metrics using the setMinimumFontMetrics API in Kotlin and Java.

Câmera e mídia

O Android 15 faz as mudanças abaixo no comportamento de câmera e mídia para apps voltados para o Android 15 ou versões mais recentes.

Restrições à solicitação da seleção de áudio

Os apps direcionados ao Android 15 precisam ser o principal ou executar um serviço em primeiro plano para solicitar a seleção de áudio. Se um app tentar solicitar a seleção quando não atender a um desses requisitos, a chamada retornará AUDIOFOCUS_REQUEST_FAILED.

Saiba mais sobre a seleção de áudio em Gerenciar seleção de áudio.

Atualização das restrições não SDK

O Android 15 inclui listas atualizadas de recursos não SDK restritos interfaces baseadas na colaboração com desenvolvedores Android e nos recursos para testes internos. Antes de restringirmos interfaces não SDK, sempre que possível, garantimos que haja alternativas públicas disponíveis.

Caso seu app não seja destinado ao Android 15, algumas destas mudanças pode não afetá-lo imediatamente. No entanto, embora seja possível acessar algumas interfaces externas ao SDK dependendo do nível desejado da API do app, é possível usar qualquer ou campo sempre apresenta um alto risco de corromper o aplicativo.

Se você não souber se o app usa interfaces externas ao SDK, será possível teste seu app para descobrir. Caso seu app dependa de ambientes externos interfaces, comece a planejar uma migração para alternativas de SDK. No entanto, entendemos que alguns aplicativos têm casos de uso válidos para o uso externas ao SDK. Se você não encontrar uma alternativa para deixar de usar uma interface externa ao SDK em um recurso no app, solicite uma nova API pública.

Para saber mais sobre as mudanças dessa versão do Android, consulte Atualizações para restrições de interfaces não SDK no Android 15. Para saber mais sobre interfaces não SDK em geral, consulte Restrições para interfaces não SDK.
