Types de services de premier plan

À partir d'Android 14 (niveau d'API 34), vous devez déclarer un type de service approprié pour chaque service de premier plan. Cela signifie que vous devez déclarer le type de service dans le fichier manifeste de votre application, et demander également l'autorisation de service de premier plan appropriée pour ce type (en plus de demander l'autorisation FOREGROUND_SERVICE). En outre, selon le type de service de premier plan, vous devrez peut-être demander des autorisations d'exécution avant de lancer le service.

Traitement multimédia

Foreground service type to declare in manifest under
android:foregroundServiceType
mediaProcessing
Permission to declare in your manifest
FOREGROUND_SERVICE_MEDIA_PROCESSING
Constant to pass to startForeground()
FOREGROUND_SERVICE_TYPE_MEDIA_PROCESSING
Runtime prerequisites
None
Description

Service for performing time-consuming operations on media assets, like converting media to different formats. The system allows this service a limited time to run; under normal circumstances, this time limit would be 6 hours out of every 24. (This limit is shared by all of an app's mediaProcessing foreground services.)

Your app should manually stop the media processing service in the following scenario:

If the timeout period is reached, the system calls the service's Service.onTimeout(int, int) method. At this time, the service has a few seconds to call Service.stopSelf(). If the service does not call Service.stopSelf(), an ANR will occur with this error message: "A foreground service of <fgs_type> did not stop within its timeout: <component_name>".

Note: Service.onTimeout(int, int) is not available on Android 14 or lower. On devices running those versions, if a media processing service reaches the timeout period, the system immediately caches the app. For this reason, your app shouldn't wait to get a timeout notification. Instead, it should terminate the foreground service or change it to a background service as soon as appropriate.

Appelez la méthode createScreenCaptureIntent() avant de démarrer le service de premier plan. Une notification d'autorisation s'affiche alors auprès de l'utilisateur. Celui-ci doit accorder l'autorisation avant que vous puissiez créer le service.

Une fois le service de premier plan créé, vous pouvez appeler MediaProjectionManager.getMediaProjection().

Description

Projetez du contenu sur un écran externe ou un appareil externe à l'aide des API MediaProjection. Il ne doit pas nécessairement s'agir de contenu exclusivement multimédia.

Autres solutions

Pour diffuser des contenus multimédias en streaming sur un autre appareil, utilisez le SDK Google Cast.

Service court

Foreground service type to declare in manifest under
android:foregroundServiceType
shortService
Permission to declare in your manifest
None
Constant to pass to startForeground()
FOREGROUND_SERVICE_TYPE_SHORT_SERVICE
Runtime prerequisites
None
Description

Quickly finish critical work that cannot be interrupted or postponed.

This type has some unique characteristics:

  • Can only run for a short period of time (about 3 minutes).
  • No support for sticky foreground services.
  • Cannot start other foreground services.
  • Doesn't require a type-specific permission, though it still requires the FOREGROUND_SERVICE permission.
  • A shortService can only change to another service type if the app is currently eligible to start a new foreground service.
  • A foreground service can change its type to shortService at any time, at which point the timeout period begins.

The timeout for shortService begins from the moment that Service.startForeground() is called. The app is expected to call Service.stopSelf() or Service.stopForeground() before the timeout occurs. Otherwise, the new Service.onTimeout() is called, giving apps a brief opportunity to call stopSelf() or stopForeground() to stop their service.

A short time after Service.onTimeout() is called, the app enters a cached state and is no longer considered to be in the foreground, unless the user is actively interacting with the app. A short time after the app is cached and the service has not stopped, the app receives an ANR. The ANR message mentions FOREGROUND_SERVICE_TYPE_SHORT_SERVICE. For these reasons, it's considered best practice to implement the Service.onTimeout() callback.

The Service.onTimeout() callback doesn't exist on Android 13 and lower. If the same service runs on such devices, it doesn't receive a timeout, nor does it ANR. Make sure that your service stops as soon as it finishes the processing task, even if it hasn't received the Service.onTimeout() callback yet.

It's important to note that if the timeout of the shortService is not respected, the app will ANR even if it has other valid foreground services or other app lifecycle processes running.

If an app is visible to the user or satisfies one of the exemptions that allow foreground services to be started from the background, calling Service.StartForeground() again with the FOREGROUND_SERVICE_TYPE_SHORT_SERVICE parameter extends the timeout by another 3 minutes. If the app isn't visible to the user and doesn't satisfy one of the exemptions, any attempt to start another foreground service, regardless of type, causes a ForegroundServiceStartNotAllowedException.

If a user disables battery optimization for your app, it's still affected by the timeout of shortService FGS.

If you start a foreground service that includes the shortService type and another foreground service type, the system ignores the shortService type declaration. However, the service must still adhere to the prerequisites of the other declared types. For more information, see the Foreground services documentation.

Application des règles Google Play pour l'utilisation des types de services de premier plan

If your app targets Android 14 or higher, you'll need to declare your app's foreground service types in the Play Console's app content page (Policy > App content). For more information on how to declare your foreground service types in Play Console, see Understanding foreground service and full-screen intent requirements.
