问题 I'm building an app that will listen for incoming SMS messages, perform some potentially long running operations and send back a reply if some conditions are met.

I also tested ACTION_USER_PRESENT and it works when the phone is unlocked, but I want to run the method before unlocking (just when the screen lock appears).
