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

Como nas versões anteriores, o Android 15 inclui mudanças de comportamento que podem afetar seu app. As seguintes mudanças de comportamento se aplicam exclusivamente a apps destinados ao Android 15 ou mais recente. 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 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

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:

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 hora em que 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 ajudar a 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.

Inicia 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:

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 têm como objetivo 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 exibidos de ponta a ponta por padrão em dispositivos com o Android 15 se o app for destinado ao Android 15 (nível 35 da API).

Um app destinado ao Android 14 e que não ocupa toda a tela em um dispositivo Android 15.


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

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

  • Barra de navegação do identificador de gestos
    • Transparente por padrão.
    • O deslocamento inferior está desativado para que o conteúdo seja mostrado por trás da barra de navegação do sistema, a menos que os insets sejam aplicados.
    • setNavigationBarColor e R.attr#navigationBarColor foram 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.
    • O deslocamento da parte de baixo foi desativado para que o conteúdo apareça por trás da barra de navegação do sistema, a menos que os insets 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 foi 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 opaco de 80% à navegação com três botões.
  • Barra de status
    • Transparente por padrão.
    • O deslocamento superior está desativado para que o conteúdo seja renderizado atrás da barra de status, a menos que os 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 efeito no Android 15.
  • Recorte 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 recorte da tela e apareçam de borda a borda.

O exemplo a seguir mostra um app antes e depois de segmentar o Android 15 (nível 35 da API) e antes e depois de aplicar insets.

Um app destinado ao Android 14 e que não ocupa toda a tela em um dispositivo Android 15.
Um app que é direcionado ao Android 15 (nível 35 da API) e ocupa toda a tela em um dispositivo Android 15. No entanto, muitos elementos agora são ocultos pela barra de status, barra de navegação de três botões ou corte da tela devido às restrições de ponta a ponta do Android 15. A interface oculta inclui a barra de apps superior do Material Design 2, botões de ação flutuantes e itens de lista.
Um app direcionado ao Android 15 (nível 35 da API) ocupa toda a tela em um dispositivo Android 15 e aplica insets para que a IU não seja oculta.
Como verificar se o app já ocupa toda a tela

Se o app já ocupa toda a tela e aplica insets, não há grande impacto, exceto nos seguintes cenários. No entanto, mesmo que você ache que não foi afetado, recomendamos testar o app.

  • Você tem uma janela não flutuante, como uma 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. É possível fazer upgrade da dependência da tela de inicialização do núcleo para 1.2.0-alpha01 ou versões mais recentes ou definir window.attributes.layoutInDisplayCutoutMode = WindowManager.LayoutInDisplayCutoutMode.always.
  • Talvez haja telas com menos tráfego e uma interface obstruída. Verifique se essas telas menos visitadas não têm uma interface oculta. As telas com menos tráfego incluem:
    • Telas de integração ou de login
    • Páginas de configurações
O que verificar se o app ainda não ocupa toda a tela

Se o app ainda não ocupa toda a tela, é provável que você seja afetado. Além dos cenários para apps que já ocupam toda a tela, considere o seguinte:

  • Se o app usar componentes do Material 3 ( androidx.compose.material3) no Compose, como TopAppBar, BottomAppBar e NavigationBar, esses componentes provavelmente não serão 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 e aplicá-los manualmente. Na 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.
  • Caso o app use visualizações e componentes do Material (com.google.android.material), a maioria dos componentes do Material baseados em visualizações, como BottomNavigationView, BottomAppBar, NavigationRailView ou NavigationView, processa encartes e não requer trabalho extra. No entanto, é necessário 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, você poderá consumir insets usando os valores de padding Scaffold. 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 personalizada em segundo plano

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

Outros recursos de ponta a ponta

Consulte os guias Visualizações de borda a borda e Composição de borda a borda para mais considerações sobre como aplicar insets.

APIs descontinuadas

As APIs a seguir foram descontinuadas, mas não foram desativadas:

As APIs a seguir foram 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 o padrão definido como "true".

Em apps destinados ao Android 15 (nível 35 da API), o atributo elegantTextHeight TextView passa a ser true por padrão, substituindo a fonte compacta usada por padrão por alguns scripts com métricas verticais grandes por uma que é muito mais legível. A fonte compacta foi introduzida para evitar a quebra de layouts. O Android 13 (nível 33 da API) evita muitas dessas quebras, permitindo que o layout de texto estique a altura vertical usando o atributo fallbackLineSpacing.

No Android 15, a fonte compacta ainda permanece no sistema. Assim, o app pode definir elegantTextHeight como false para ter o mesmo comportamento de antes, mas é improvável que haja suporte a ele nas próximas versões. Portanto, se o app oferecer suporte aos seguintes scripts: árabe, lao, birmanês, tâmil, gujarati, canarês, malaiala, odia, télugo ou tailandês, teste o app definindo elegantTextHeight como true.

elegantTextHeight comportamento para apps destinados ao Android 14 (nível 34 da API) e versões anteriores.
Comportamento elegantTextHeight para apps destinados ao Android 15.

A largura do 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 de linha padrão compatível com a 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 da câmera e da mídia para apps destinados ao Android 15 ou mais recente.

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

Android 15 includes updated lists of restricted non-SDK interfaces based on collaboration with Android developers and the latest internal testing. Whenever possible, we make sure that public alternatives are available before we restrict non-SDK interfaces.

If your app does not target Android 15, some of these changes might not immediately affect you. However, while it's possible for your app to access some non-SDK interfaces depending on your app's target API level, using any non-SDK method or field always carries a high risk of breaking your app.

If you are unsure if your app uses non-SDK interfaces, you can test your app to find out. If your app relies on non-SDK interfaces, you should begin planning a migration to SDK alternatives. Nevertheless, we understand that some apps have valid use cases for using non-SDK interfaces. If you can't find an alternative to using a non-SDK interface for a feature in your app, you should request a new public API.

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.
