Solution

This from https://stackoverflow.com/a/19320065/619673 Solved my problem

I added this code to my activity because I used the theme "no title" in the activity

@Override
public boolean onKeyDown(int keyCode,KeyEvent event) {
    if ( keyCode == KeyEvent.KEYCODE_MENU ) {
        // do nothing
        return true;
    }
    return super.onKeyDown(keyCode,event);
}
