Foreground service types

Beginning with Android 14 (API level 34), you must declare an appropriate service type for each foreground service. That means you must declare the service type in your app manifest, and also request the appropriate foreground service permission for that type (in addition to requesting the FOREGROUND_SERVICE permission). Furthermore, depending on the foreground service type, you might have to request runtime permissions before you launch the service.

Camera

Foreground service type to declare in manifest under android:foregroundServiceType: camera
Permission to declare in your manifest: FOREGROUND_SERVICE_CAMERA
Constant to pass to startForeground(): FOREGROUND_SERVICE_TYPE_CAMERA
Runtime prerequisites: Request and be granted the CAMERA runtime permission

Note: The CAMERA runtime permission is subject to while-in-use restrictions. For this reason, you cannot create a camera foreground service while your app is in the background and you cannot launch a camera foreground service from a BOOT_COMPLETED receiver, with a few exceptions. For more information, see Restrictions on starting foreground services that need while-in-use permissions.
Description: Continue to access the camera from the background, such as video chat apps that allow for multitasking.

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.

location

Permission to declare in your manifest

FOREGROUND_SERVICE_LOCATION

Constant to pass to startForeground()

FOREGROUND_SERVICE_TYPE_LOCATION

Runtime prerequisites

The user must have enabled location services and the app must be granted at least one of the following runtime permissions:

Description

Long-running use cases that require location access, such as navigation and location sharing.

Alternatives

If your app needs to be triggered when the user reaches specific locations, consider using the geofence API instead.

Media

Foreground service type to declare in manifest under
android:foregroundServiceType: mediaPlayback
Permission to declare in your manifest: FOREGROUND_SERVICE_MEDIA_PLAYBACK
Constant to pass to startForeground(): FOREGROUND_SERVICE_TYPE_MEDIA_PLAYBACK
Runtime prerequisites: None
Description: Continue audio or video playback from the background. Support Digital Video Recording (DVR) functionality on Android TV.

Note: Apps that target Android 15 or higher are not allowed to launch a media playback foreground service from a BOOT_COMPLETED broadcast receiver. For more information, see Restrictions on BOOT_COMPLETED broadcast receivers launching foreground services.
Alternatives: If you're showing picture-in-picture video, use Picture-in-Picture mode.

Media processing

要在清单中的以下位置声明的前台服务类型

android:foregroundServiceType

mediaProcessing

在清单中声明的权限

FOREGROUND_SERVICE_MEDIA_PROCESSING

要传递给 startForeground() 的常量

FOREGROUND_SERVICE_TYPE_MEDIA_PROCESSING

运行时前提条件

无

说明

用于对媒体资源执行耗时的操作（例如将媒体转换为其他格式）的服务。系统允许此服务运行的时间有限；在正常情况下，此时限为每天 24 小时中的 6 小时。（此限制由应用的所有 mediaProcessing 前台服务共享。）

在以下情况下，您的应用应手动停止媒体处理服务：

当转码操作完成或达到失败状态时，让服务调用 Service.stopForeground() 和 Service.stopSelf() 以完全停止服务。

如果超时期限已到，系统会调用服务的 Service.onTimeout(int, int) 方法。此时，该服务有几秒钟的时间来调用 Service.stopSelf()。如果服务未调用 Service.stopSelf()，则会发生 ANR，并显示以下错误消息：“<fgs_type> 的前台服务未在超时时间内停止：<component_name>”。

注意：Service.onTimeout(int, int) 不适用于 Android 14 或更低版本。在搭载这些版本的设备上，如果媒体处理服务达到超时期限，系统会立即缓存应用。因此，您的应用不应等待收到超时通知。相反，它应在适当情况下尽快终止前台服务或将其更改为后台服务。

Media projection

Foreground service type to declare in manifest under
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.

Note: Apps that target Android 15 or higher are not allowed to launch a media projection foreground service from a BOOT_COMPLETED broadcast receiver. For more information, see Restrictions on BOOT_COMPLETED broadcast receivers launching foreground services.
Alternatives: To stream media to another device, use the Google Cast SDK.

Microphone

Foreground service type to declare in manifest under
android:foregroundServiceType: microphone
Permission to declare in your manifest: FOREGROUND_SERVICE_MICROPHONE
Constant to pass to startForeground(): FOREGROUND_SERVICE_TYPE_MICROPHONE
Runtime prerequisites: Request and be granted the RECORD_AUDIO runtime permission.

Note: The RECORD_AUDIO runtime permission is subject to while-in-use restrictions. For this reason, you cannot create a microphone foreground service while your app is in the background and you cannot launch a microphone foreground service from a BOOT_COMPLETED receiver, with a few exceptions. For more information, see Restrictions on starting foreground services that need while-in-use permissions.
Description: Continue microphone capture from the background, such as voice recorders or communication apps.

Phone call

Foreground service type to declare in manifest under

android:foregroundServiceType

phoneCall

Permission to declare in your manifest

FOREGROUND_SERVICE_PHONE_CALL

Constant to pass to startForeground()

FOREGROUND_SERVICE_TYPE_PHONE_CALL

Runtime prerequisites

At least one of these conditions must be true:

App has declared the MANAGE_OWN_CALLS permission in its manifest file.

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.

Remote messaging

Foreground service type to declare in manifest under
android:foregroundServiceType: remoteMessaging
Permission to declare in your manifest: FOREGROUND_SERVICE_REMOTE_MESSAGING
Constant to pass to startForeground(): FOREGROUND_SERVICE_TYPE_REMOTE_MESSAGING
Runtime prerequisites: None
Description: Transfer text messages from one device to another. Assists with continuity of a user's messaging tasks when they switch devices.

Short service

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.

Special use

Foreground service type to declare in manifest under

android:foregroundServiceType

specialUse

Permission to declare in your manifest

FOREGROUND_SERVICE_SPECIAL_USE

Constant to pass to startForeground()

FOREGROUND_SERVICE_TYPE_SPECIAL_USE

Runtime prerequisites

None

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>

System exempted

Foreground service type to declare in manifest under

android:foregroundServiceType

systemExempted

Permission to declare in your manifest

FOREGROUND_SERVICE_SYSTEM_EXEMPTED

Constant to pass to startForeground()

FOREGROUND_SERVICE_TYPE_SYSTEM_EXEMPTED

Runtime prerequisites

None

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
VPN apps (configured using Settings > Network & Internet > VPN)

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

Google Play policy enforcement for using foreground service types

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.
