how to show popup Activity or Dialog when phone is locked?

Question

I am trying to show a activity or a dialog when the phone is locked. I have tried using a WakeLock but it did not work and I can only see the activity once my phone is unloc

Answer 1

To show activity without dismissing the keyguard try this:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
setContentView();
