I have an Android app that connects to surrounding devices currently running the same app, even if in background.
To do this, I use WiF-Direct to advertise the fact that I am currently running said application.
Therefore I need to stop advertising this as soon as the app is killed.
onDestroy() cannot be used since it is not guaranteed to be called.onStop() and onPause() cannot be used since the app is still running.
How can I achieve this?
Currently the service is still being advertised even when the application is closed/killed.
You should be able to do this with a Service.
Start a service when your app was started.
Override the onTaskRemoved method
@Override
public void onTaskRemoved(Intent rootIntent)
{
}
In this method do what you have to do.

The best implementation might be to have another service running that queries the your app is in foreground(i.e. running)
You can run the query to check periodically say every 60 sec. Then if the app isn't running. You can stop the WiFi Direct service and subsequently stop self.
