android start activity from service

Question

Android:

public class LocationService extends Service {

@Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startI         


        

Answer 1

Another thing worth mentioning: while the answer above works just fine when our task is in the background, the only way I could make it work if our task (made of service + some activities) was in the foreground (i.e. one of our activities visible to user) was like this:

    Intent intent = new Intent(storedActivity, MyActivity.class);
    intent.setAction(Intent.ACTION_VIEW);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
    storedActivity.startActivity(intent);

I do not know whether ACTION_VIEW or FLAG_ACTIVITY_NEW_TASK are of any actual use here. The key to succeeding was

storedActivity.startActivity(intent);

and of course FLAG_ACTIVITY_REORDER_TO_FRONT for not instantiating the activity again. Best of luck!
