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:

• When the transcoding operation finishes or reaches a failure state, have the service call Service.stopForeground() and Service.stopSelf() to stop the service completely.

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.
