Mudanças de comportamento: apps destinados ao Android 15 ou mais recente

Assim como nas 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 destinados ao Android 15 ou versões mais recentes. Caso seu app seja direcionado ao Android 15 ou a versões mais recentes, faça modificações para oferecer suporte a esses comportamentos de forma adequada, quando aplicável.

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

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

Há novas restrições para inicialização de broadcast receivers BOOT_COMPLETED serviços em primeiro plano. Receptores BOOT_COMPLETED não têm permissão para iniciar o seguintes tipos de serviços em primeiro plano:

Se um receptor BOOT_COMPLETED tentar iniciar qualquer um desses tipos de primeiro plano serviços, o sistema gera ForegroundServiceStartNotAllowedException.

Teste

Para testar o comportamento do app, ative essas novas restrições mesmo que seu O app não é destinado ao Android 15, desde que seja executado em um Android 15 dispositivo). Execute o seguinte comando adb:

adb shell am compat enable FGS_BOOT_COMPLETED_RESTRICTIONS your-package-name

Para enviar uma transmissão BOOT_COMPLETED sem reiniciar o dispositivo: Execute o seguinte comando adb:

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 em quando os apps podem modificar o estado global do modo Não perturbe

Apps that target Android 15 (API level 35) and higher can no longer change the global state or policy of Do Not Disturb (DND) on a device (either by modifying user settings, or turning off DND mode). Instead, apps must contribute an AutomaticZenRule, which the system combines into a global policy with the existing most-restrictive-policy-wins scheme. Calls to existing APIs that previously affected global state (setInterruptionFilter, setNotificationPolicy) result in the creation or update of an implicit AutomaticZenRule, which is toggled on and off depending on the call-cycle of those API calls.

Note that this change only affects observable behavior if the app is calling setInterruptionFilter(INTERRUPTION_FILTER_ALL) and expects that call to deactivate an AutomaticZenRule that was previously activated by their owners.

Mudanças na API OpenJDK

Android 15 continues the work of refreshing Android's core libraries to align with the features in the latest OpenJDK LTS releases.

Some of these changes can affect app compatibility for apps targeting Android 15 (API level 35):

  • Changes to string formatting APIs: Validation of argument index, flags, width, and precision are now more strict when using the following String.format() and Formatter.format() APIs:

    For example, the following exception is thrown when an argument index of 0 is used (%0 in the format string):

    IllegalFormatArgumentIndexException: Illegal format argument index = 0

    In this case, the issue can be fixed by using an argument index of 1 (%1 in the format string).

  • Changes to component type of Arrays.asList(...).toArray(): When using Arrays.asList(...).toArray(), the component type of the resulting array is now an Object—not the type of the underlying array's elements. So the following code throws a ClassCastException:

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

    For this case, to preserve String as the component type in the resulting array, you could use Collection.toArray(Object[]) instead:

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

  • Changes to language code handling: When using the Locale API, language codes for Hebrew, Yiddish, and Indonesian are no longer converted to their obsolete forms (Hebrew: iw, Yiddish: ji, and Indonesian: in). When specifying the language code for one of these locales, use the codes from ISO 639-1 instead (Hebrew: he, Yiddish: yi, and Indonesian: id).

  • Changes to random int sequences: Following the changes made in https://bugs.openjdk.org/browse/JDK-8301574, the following Random.ints() methods now return a different sequence of numbers than the Random.nextInt() methods do:

    Generally, this change shouldn't result in app-breaking behavior, but your code shouldn't expect the sequence generated from Random.ints() methods to match Random.nextInt().

The new SequencedCollection API can affect your app's compatibility after you update compileSdk in your app's build configuration to use Android 15 (API level 35):

  • Collision with MutableList.removeFirst() and MutableList.removeLast() extension functions in kotlin-stdlib

    The List type in Java is mapped to the MutableList type in Kotlin. Because the List.removeFirst() and List.removeLast() APIs have been introduced in Android 15 (API level 35), the Kotlin compiler resolves function calls, for example list.removeFirst(), statically to the new List APIs instead of to the extension functions in kotlin-stdlib.

    If an app is re-compiled with compileSdk set to 35 and minSdk set to 34 or lower, and then the app is run on Android 14 and lower, a runtime error is thrown:

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

    The existing NewApi lint option in Android Gradle Plugin can catch these new API usages.

    ./gradlew lint

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

    To fix the runtime exception and lint errors, the removeFirst() and removeLast() function calls can be replaced with removeAt(0) and removeAt(list.lastIndex) respectively in Kotlin. If you're using Android Studio Ladybug | 2024.1.3 or higher, it also provides a quick fix option for these errors.

    Consider removing @SuppressLint("NewApi") and lintOptions { disable 'NewApi' } if the lint option has been disabled.

  • Collision with other methods in Java

    New methods have been added into the existing types, for example, List and Deque. These new methods might not be compatible with the methods with the same name and argument types in other interfaces and classes. In the case of a method signature collision with incompatibility, the javac compiler outputs a build-time error. For example:

    Example error 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

    Example error 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

    Example error 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

    To fix these build errors, the class implementing these interfaces should override the method with a compatible return type. For example:

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

Segurança

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

Versões TLS restritas

Android 15 restricts the usage of TLS versions 1.0 and 1.1. These versions had previously been deprecated in Android, but are now disallowed for apps targeting Android 15.

Início de atividades em segundo plano protegidas

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:

Kotlin

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

Java

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 experiência do usuário mais consistente e intuitiva.

Mudanças no encarte da janela

There are two changes related to window insets in Android 15: edge-to-edge is enforced by default, and there are also configuration changes, such as the default configuration of system bars.

Edge-to-edge enforcement

Os apps são de ponta a ponta por padrão em dispositivos com Android 15 se o app for destinado ao Android 15 (nível 35 da API).

Um app destinado ao Android 14 que não é de ponta a ponta em um dispositivo Android 15.


Um app direcionado ao Android 15 (nível 35 da API) e que é de ponta a ponta em um dispositivo Android 15. Este app usa principalmente componentes do Material 3 para Compose que aplicam encartes automaticamente. Essa tela não é afetada negativamente pela restrição de ponta a ponta do Android 15.

Essa é uma mudança incompatível que pode afetar negativamente a interface do seu app. As mudanças afetam as seguintes áreas da interface:

  • Barra de navegação com alça de gesto
    • Transparente por padrão.
    • O deslocamento da parte de baixo está desativado, então o conteúdo é mostrado por trás da barra de navegação do sistema, a menos que encartes sejam aplicados.
    • setNavigationBarColor e R.attr#navigationBarColor estão descontinuados e não afetam a navegação por gestos.
    • setNavigationBarContrastEnforced e R.attr#navigationBarContrastEnforced continuam sem efeito na navegação por gestos.
  • Navegação com três botões
    • Opacidade definida como 80% por padrão, com a cor possivelmente correspondendo ao plano de fundo da janela.
    • Deslocamento da parte de baixo desativado para que o conteúdo seja mostrado por trás da barra de navegação do sistema, a menos que encartes sejam aplicados.
    • setNavigationBarColor e R.attr#navigationBarColor são definidos para corresponder ao plano de fundo da janela por padrão. O plano de fundo da janela precisa ser um drawable de cor para que esse padrão seja aplicado. Essa API está descontinuada, mas continua afetando a navegação com três botões.
    • setNavigationBarContrastEnforced e R.attr#navigationBarContrastEnforced são verdadeiros por padrão, o que adiciona um plano de fundo 80% opaco na navegação com três botões.
  • Barra de status
    • Transparente por padrão.
    • O deslocamento da parte de cima é desativado para que o conteúdo seja mostrado por trás da barra de status, a menos que encartes sejam aplicados.
    • setStatusBarColor e R.attr#statusBarColor foram descontinuados e não têm efeito no Android 15.
    • setStatusBarContrastEnforced e R.attr#statusBarContrastEnforced foram descontinuados, mas ainda têm um efeito no Android 15.
  • Corte da tela
    • O layoutInDisplayCutoutMode de janelas não flutuantes precisa ser LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS. SHORT_EDGES, NEVER e DEFAULT são interpretados como ALWAYS para que os usuários não vejam uma barra preta causada pelo corte da tela e apareçam de ponta a ponta.

O exemplo a seguir mostra um app antes e depois de ser direcionado ao Android 15 (nível 35 da API) e antes e depois de aplicar encartes.

Um app destinado ao Android 14 que não é de ponta a ponta em um dispositivo Android 15.
Um app que tem como destino o Android 15 (nível 35 da API) e é de ponta a ponta em um dispositivo Android 15. No entanto, muitos elementos agora estão ocultos pela barra de status, pela barra de navegação de três botões ou pelo corte da tela devido às imposições de ponta a ponta do Android 15. A interface oculta inclui a barra de apps superior do Material 2, botões de ação flutuantes e itens de lista.
Um app que é direcionado ao Android 15 (nível 35 da API), é de ponta a ponta em um dispositivo Android 15 e aplica encartes para que a interface não fique oculta.
O que verificar se o app já é de ponta a ponta

Se o app já for de ponta a ponta e aplicar encartes, você não será muito afetado, exceto nos seguintes cenários. No entanto, mesmo que você não ache que foi afetado, recomendamos que teste seu app.

  • Você tem uma janela não flutuante, como um Activity que usa SHORT_EDGES, NEVER ou DEFAULT em vez de LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS. Se o app falhar na inicialização, isso pode ser devido à tela de apresentação. Você pode fazer upgrade da dependência core splashscreen para 1.2.0-alpha01 ou uma versão mais recente ou definir window.attributes.layoutInDisplayCutoutMode = WindowManager.LayoutInDisplayCutoutMode.always.
  • Pode haver telas com menos tráfego e interface obstruída. Verifique se essas telas menos visitadas não têm uma interface do usuário ocluída. As telas com menos tráfego incluem:
    • Telas de onboarding ou login
    • Páginas de configurações
O que verificar se o app ainda não é de ponta a ponta

Se o app ainda não estiver de ponta a ponta, é provável que você seja afetado. Além dos cenários para apps que já são de ponta a ponta, considere o seguinte:

  • Se o app usar componentes do Material 3 ( androidx.compose.material3) no Compose, como TopAppBar, BottomAppBar e NavigationBar, é provável que esses componentes não sejam afetados porque processam encartes automaticamente.
  • Se o app estiver usando componentes do Material 2 ( androidx.compose.material) no Compose, eles não vão processar encartes automaticamente. No entanto, você pode conseguir acesso aos encartes para fazer a aplicação manual. No androidx.compose.material 1.6.0 e versões mais recentes, use o parâmetro windowInsets para aplicar os encartes manualmente para BottomAppBar, TopAppBar, BottomNavigation e NavigationRail. Da mesma forma, use o parâmetro contentWindowInsets para Scaffold.
  • Se o app usar views e componentes do Material Design (com.google.android.material), a maioria dos componentes do Material baseados em views, como BottomNavigationView, BottomAppBar, NavigationRailView ou NavigationView, processa encartes e não exige mais trabalho. No entanto, você precisará adicionar android:fitsSystemWindows="true" se estiver usando AppBarLayout.
  • Para elementos combináveis personalizados, aplique os encartes manualmente como padding. Se o conteúdo estiver em um Scaffold, use os valores de padding Scaffold de encartes. Caso contrário, aplique o padding usando um dos WindowInsets.
  • Se o app estiver usando visualizações e BottomSheet, SideSheet ou contêineres personalizados, aplique padding usando ViewCompat.setOnApplyWindowInsetsListener. Para RecyclerView, aplique padding usando esse listener e também adicione clipToPadding="false".
O que verificar se o app precisa oferecer proteção de plano de fundo personalizada

Se o app precisar oferecer proteção de plano de fundo personalizada para a navegação com três botões ou a barra de status, ele deverá colocar um elemento combinável ou uma visualização atrás da barra de sistema usando WindowInsets.Type#tappableElement() para receber a altura da barra de navegação com três botões ou WindowInsets.Type#statusBars.

Outros recursos de ponta a ponta

Consulte os guias Visualizações de ponta a ponta e Compose de ponta a ponta para mais considerações sobre a aplicação de encartes.

APIs descontinuadas

As APIs a seguir estão descontinuadas, mas não desativadas:

As seguintes APIs estão descontinuadas e desativadas:

Stable configuration

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:

O atributo "elegantTextHeight" tem como padrão o valor "true".

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.

elegantTextHeight behavior for apps targeting Android 14 (API level 34) and lower.
elegantTextHeight behavior for apps targeting Android 15.

A largura da TextView muda para formas de letras 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 sensível à 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:

Three boxes representing EditText elements that can contain text from English (en), Japanese (ja), and Burmese (my). The height of the EditText is the same, even though these languages have different line heights from each other.

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:

Three boxes representing EditText elements that can contain text from English (en), Japanese (ja), and Burmese (my). The height of the EditText now includes space to accommodate the default line height for these languages' fonts.

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 seguintes mudanças no comportamento de mídia e câmera para apps direcionados ao Android 15 ou versões mais recentes.

Restrições ao solicitar o foco de áudio

Apps that target Android 15 (API level 35) must be the top app or running a foreground service in order to request audio focus. If an app attempts to request focus when it does not meet one of these requirements, the call returns AUDIOFOCUS_REQUEST_FAILED.

You can learn more about audio focus at Manage audio focus.

Atualização das restrições não SDK

O Android 15 inclui listas atualizadas de interfaces não SDK restritas com base na colaboração com desenvolvedores Android e nos testes internos mais recentes. Antes de restringirmos interfaces não SDK, sempre que possível, garantimos que haja alternativas públicas disponíveis.

Caso seu app não seja destinado ao Android 15, é possível que algumas dessas mudanças não afetem você imediatamente. No entanto, embora seja possível que seu app acesse algumas interfaces não SDK dependendo do nível da API de destino do app, o uso de qualquer método ou campo não SDK sempre apresenta um alto risco de corromper o app.

Se você não souber se seu app usa interfaces não SDK, poderá testá-lo para descobrir. Se ele depende de interfaces não SDK, comece a planejar uma migração para alternativas SDK. No entanto, entendemos que alguns apps têm casos de uso válidos para interfaces não SDK. Se você não encontrar uma alternativa para deixar de usar uma interface não SDK em um recurso no seu app, solicite uma nova API pública.

To learn more about the changes in this release of Android, see Updates to non-SDK interface restrictions in Android 15. To learn more about non-SDK interfaces generally, see Restrictions on non-SDK interfaces.
