포그라운드 서비스 유형

Android 14 (API 수준 34)부터는 적합한 API를 사용하여 서비스 유형을 지정합니다 즉, 서비스 유형을 지정하고 적절한 포그라운드 요청도 서비스 권한을 요청하는 것 외에 FOREGROUND_SERVICE 권한이 있는지 확인하세요. 또한 포그라운드 서비스 유형에 따라 서비스를 실행하기 전에 런타임 권한을 요청해야 할 수도 있습니다.

At least one of the following conditions must be true:

Description

Interactions with external devices that require a Bluetooth, NFC, IR, USB, or network connection.

Alternatives

If your app needs to do continuous data transfer to an external device, consider using the companion device manager instead. Use the companion device presence API to help your app stay running while the companion device is in range.

If your app needs to scan for bluetooth devices, consider using the Bluetooth scan API instead.

미디어 처리 중

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.

android:foregroundServiceType
mediaProjection
Permission to declare in your manifest
FOREGROUND_SERVICE_MEDIA_PROJECTION
Constant to pass to startForeground()
FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION
Runtime prerequisites

Call the createScreenCaptureIntent() method before starting the foreground service. Doing so shows a permission notification to the user; the user must grant the permission before you can create the service.

After you have created the foreground service, you can call MediaProjectionManager.getMediaProjection().

Description

Project content to non-primary display or external device using the MediaProjection APIs. This content doesn't have to be exclusively media content.

Alternatives

To stream media to another device, use the Google Cast SDK.

At least one of these conditions must be true:

  • App is the default dialer app through the ROLE_DIALER role.
Description

Continue an ongoing call using the ConnectionService APIs.

Alternatives

If you need to make phone, video, or VoIP calls, consider using the android.telecom library.

Consider using CallScreeningService to screen calls.

짧은 서비스

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.
