title: Android -- What happens when device is unlocked?
body: <p>I am trying to understand the intents that get launched when the device is unlocked. </p>
  
  <p>For eg: Say my activity is running, and I press the power button (screen off, to lock the phone). INTENT.ACTION_SCREEN_OFF is launched. The activity is paused and the screen goes blank. </p>
  
  <p>Now, when I press the power button again (INTENT.SCREEN_ON gets launched), the activity's onResume method is called. But the device is not yet unlocked. </p>
  
  <p>What happens when the device is unlocked? To put it simply, what is the intent's action and category?</p>
