Answer 1

You need override onKeyDown and onKeyUp events to detect two buttons pressed.

 public boolean first,second;

 public boolean onKeyDown(int keyCode, KeyEvent event) {

    if (keyCode == KeyEvent.KEYCODE_POWER){
        first = true;
    }
    else if(keyCode == KeyEvent.KEYCODE_VOLUME_UP){
        second = true;
    }

    if(first && second) {
        // Two buttons pressed, Do your stuff
    }
    return true;
 }

 public boolean onKeyUp(int keyCode, KeyEvent event) {

    if (keyCode == KeyEvent.KEYCODE_POWER){
        first = false;
    }
    else if(keyCode == KeyEvent.KEYCODE_VOLUME_UP){
        second = false;
    }
    return true;
 }
