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:
camera
connectedDevice
dataSync
health
location
mediaPlayback
mediaProjection
microphone
phoneCall
remoteMessaging
shortService
specialUse
systemExempted
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.
Declare new permission to use foreground service types
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.
Include foreground service type at runtime
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
.
System runtime checks
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.
Intended use cases and enforcement for each foreground service type
In order to use a given foreground service type, you must declare a particular permission in your manifest file, you must fulfill specific runtime requirements, and your app must fulfill one of the intended sets of use cases for that type. The following sections explain the permission that you must declare, the runtime prerequisites, and the intended use cases for each type.

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 callService.stopSelf()
orService.stopForeground()
before the timeout occurs. Otherwise, the newService.onTimeout()
is called, giving apps a brief opportunity to callstopSelf()
orstopForeground()
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 mentionsFOREGROUND_SERVICE_TYPE_SHORT_SERVICE
. For these reasons, it's considered best practice to implement theService.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 theService.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 theFOREGROUND_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 aForegroundServiceStartNotAllowedException
.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 theshortService
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

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 thespecialUse

role - Device Admin apps
- Apps holding
SCHEDULE_EXACT_ALARM
orUSE_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
.
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.
