How To Get The Power And Back Key Event In Android.

Hello friends,If you want to perform an action with power and back key pressed look into following.

1)Add this following method in your Activity.(For Power Button Pressed)

 public boolean dispatchKeyEvent(KeyEvent event)
 {
 if (event.getKeyCode() == KeyEvent.KEYCODE_POWER) {
  
 Toast.makeText(getApplicationContext(), "Power button clicked",Toast.LENGTH_LONG).show();

       return true;
 }
     return super.dispatchKeyEvent(event);
}



2)Next,Add this following in your Activity.(For Back Key Pressed)

 @Override
 public void onBackPressed() 
{
        finish();
}

Thanks..
