Answer 1

You can try this trick .

Register a Broadcast Receiver which is initiated when powerbutton is clicked. Now in OnReceive method of the Receiver do what you want.

For example:

in manifest file register a receiver:

&& in onReceive() method of the Receiver

 public class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context arg0, Intent arg1) {
        // TODO Auto-generated method stub

         Log.v("#@%@%#", "Power button is pressed.");  

         Toast.makeText(arg0, "power button clicked",Toast.LENGTH_LONG).show();

        //perform what you want here
    }
}

Now perform any operation in onReceive() method of the Receiver.
