My app needs to capture and then disable the multitasking key, however it does not work even I used either KEYCODE_MENU or KEYCODE_APP_SWITCH:

public boolean onKeyDown(int keyCode, KeyEvent event) {
    // TODO Auto-generated method stub

    if(keyCode == KeyEvent.KEYCODE_BACK) { //shield Back Key
        Log.i(TAG, "shield Back Key");
        return true;
    } else if(keyCode == KeyEvent.KEYCODE_MENU) { //shield Menu Key
        Log.i(TAG, "shield Menu Key");
        return true;
    } else if(keyCode == KeyEvent.KEYCODE_HOME) { //this does not work
        return true;
    }else if(keyCode == KeyEvent.KEYCODE_APP_SWITCH) { //shield Multiple Key
        Log.i(TAG, "shield Mutiple Key");
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

How can we do it? Thanks.
