Answer 1

I don't think you can hide that since that would be equivalent to hiding the hard buttons on other devices. What you could do is handle their presses.

        @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
           // do something
            return true;
        } else if (keyCode==KeyEvent.KEYCODE_HOME){
  //do something
return true;
    }
        return super.onKeyDown(keyCode, event);
    }
