[Android-development] Activity not starting with foreground service

[Filip Piechocki]

But the use case is that user relaunches the app while the service part is
always there. Let's put it this way - service is doing all the job and it
is doing it continuously. Activity is just a UI frontend showing current
state of the backend service processing. Service does not care if frontend
is shown or not and thus cannot relaunch it with Intent as it does not know
when the frontend is needed.

Filip
