フォアグラウンド サービス タイプは必須

To help developers be more intentional with defining user-facing foreground services, Android 10 introduced the android:foregroundServiceType attribute within the <service> element.

If your app targets Android 14, it must specify appropriate foreground service types. As in previous versions of Android, multiple types can be combined. This list shows the foreground service types to choose from:

If a use case in your app isn't associated with any of these types, we strongly recommend that you migrate your logic to use WorkManager or user-initiated data transfer jobs.

The health, remoteMessaging, shortService, specialUse, and systemExempted types are new in Android 14.

The following code snippet provides an example of a foreground service type declaration in the manifest:

<manifest ...>
  <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
  <uses-permission android:name="android.permission.FOREGROUND_SERVICE_MEDIA_PLAYBACK" />
    <application ...>
      <service
          android:name=".MyMediaPlaybackService"
          android:foregroundServiceType="mediaPlayback"
          android:exported="false">
      </service>
    </application>
</manifest>

If an app that targets Android 14 doesn't define types for a given service in the manifest, then the system will raise MissingForegroundServiceTypeException upon calling startForeground() for that service.

フォアグラウンド サービス タイプを使用する新しい権限を宣言する

If apps that target Android 14 use a foreground service, they must declare a specific permission, based on the foreground service type, that Android 14 introduces. These permissions appear in the sections labeled "permission that you must declare in your manifest file" in the intended use cases and enforcement for each foreground service type section on this page.

All of the permissions are defined as normal permissions and are granted by default. Users cannot revoke these permissions.

実行時にフォアグラウンド サービス タイプを含める

The best practice for applications starting foreground services is to use the ServiceCompat version of startForeground() (available in androidx-core 1.12 and higher) where you pass in a bitwise integer of foreground service types. You can choose to pass one or more type values.

Usually, you should declare only the types required for a particular use case. This makes it easier to meet the system's expectations for each foreground service type. In cases where a foreground service is started with multiple types, then the foreground service must adhere to the platform enforcement requirements of all types.

ServiceCompat.startForeground(0, notification, FOREGROUND_SERVICE_TYPE_LOCATION)

If the foreground service type is not specified in the call, the type defaults to the values defined in the manifest. If you didn't specify the service type in the manifest, the system throws MissingForegroundServiceTypeException.

If the foreground service needs new permissions after you launch it, you should call startForeground() again and add the new service types. For example, suppose a fitness app runs a running-tracker service that always needs location information, but might or might not need media permissions. You would need to declare both location and mediaPlayback in the manifest. If a user starts a run and just wants their location tracked, your app should call startForeground() and pass just the location service type. Then, if the user wants to start playing audio, call startForeground() again and pass location|mediaPlayback.

システムによるランタイム チェック

The system checks for proper use of foreground service types and confirms that the app has requested the proper runtime permissions or uses the required APIs. For instance, the system expects apps that use the foreground service type FOREGROUND_SERVICE_TYPE_LOCATION type to request either ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION.

This implies that apps must follow a very specific order of operations when requesting permissions from the user and starting foreground services. Permissions must be requested and granted before the app attempts to call startForeground(). Apps that request the appropriate permissions after the foreground service has been started must change this order of operations and request the permission before starting the foreground service.

The specifics of platform enforcement appear in the sections labeled "runtime requirements" in the intended use cases and enforcement for each foreground service type section on this page.

各フォアグラウンド サービス タイプの対象ユースケースと適用

为了使用给定的前台服务类型,您必须在清单文件中声明特定权限,必须满足特定的运行时要求,并且应用必须满足该类型的其中一组预期用例。以下部分介绍了您必须声明的权限、运行时前提条件以及每种类型的预期用例。

ショート サービス

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.

Description

Covers any valid foreground service use cases that aren't covered by the other foreground service types.

In addition to declaring the FOREGROUND_SERVICE_TYPE_SPECIAL_USE foreground service type, developers should declare use cases in the manifest. To do so, they specify the <property> element within the <service> element. These values and corresponding use cases are reviewed when you submit your app in the Google Play Console. The use cases you provide are free-form, and you should make sure to provide enough information to let the reviewer see why you need to use the specialUse type.

<service android:name="fooService" android:foregroundServiceType="specialUse">
  <property android:name="android.app.PROPERTY_SPECIAL_USE_FGS_SUBTYPE"
      android:value="explanation_for_special_use"/>
</service>

Description

Reserved for system applications and specific system integrations, to continue to use foreground services.

To use this type, an app must meet at least one of the following criteria:

  • Device is in demo mode state
  • App is a Device Owner
  • App is a Profiler Owner
  • Safety Apps that have the ROLE_EMERGENCY role
  • Device Admin apps
  • Apps holding SCHEDULE_EXACT_ALARM or USE_EXACT_ALARM permission and are using Foreground Service to continue alarms in the background, including haptics-only alarms.
  • VPN apps (configured using Settings > Network & Internet > VPN)

    Otherwise, declaring this type causes the system to throw a ForegroundServiceTypeNotAllowedException.
