How to start activity from service in Android10

问题

I was starting activity from services till android P, but from android10 google has kept one restriction that activity cannot be started from background.

https://developer.android.com/guide/components/activities/background-starts

// below code stopped working
Intent intent = new Intent(this, MyActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

what should i do for android10 ?

回答1:

You can use a notification using setFullScreenIntent, it's the best you can do or you can ask for SYSTEM_ALERT_WINDOW permission but it doesn't work with android go devices.
