Bring application to background and then to foreground

What method should I use to move my app to background and then move it to foreground again?
I tried using moveTaskToBack(true) and the activity is moved to background successfully but then I can't move it to foreground.
I tried starting the activity again using startActivity() but with no success and there seems to be no method moveTaskToFront() or something similar.

Answer

Use moveTaskToBack() to move your app to the background.

To move it to the foreground, use the following code:

Intent intent = getPackageManager().getLaunchIntentForPackage(getPackageName());
startActivity(intent);

If you are trying to do this from a Service or BroadcastReceiver then you will need to do this before calling startActivity():

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
