startForeground(int, android.app.Notification) once it begins running.

Remarks
Similar to #startService(Intent), but with an implicit promise that the Service will call android.app.Service#startForeground(int, android.app.Notification) startForeground(int, android.app.Notification) once it begins running. The service is given an amount of time comparable to the ANR interval to do this, otherwise the system will automatically crash the process, in which case an internal exception ForegroundServiceDidNotStartInTimeException is logged on logcat on devices running SDK Version android.os.Build.VERSION_CODES#S or later. On older Android versions, an internal exception RemoteServiceException is logged instead, with a corresponding message.
Unlike the ordinary #startService(Intent), this method can be used at any time, regardless of whether the app hosting the service is in a foreground state.
<div class="caution">
<strong>Note:</strong> Beginning with SDK Version android.os.Build.VERSION_CODES#S, apps targeting SDK Version android.os.Build.VERSION_CODES#S or higher are not allowed to start foreground services from the background. See
Behavior changes: Apps targeting Android 12
