Question

I can start activity from service but I cannot restart it, this flag only brings to front the existing activity:

myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

how could I restart (finish the old, start new)?

Answer 1

It’s bit a trickery but what you can do is to add something like RESTART=true to the intent that calls the Activity. In activity’s onResume you can do getIntent and see if that flag exists and if so call finish() and call activity anew
