I think I found out how it works... DON'T USE WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE in your overlays views + overwrite the dispatchKeyEvent of your view:

 @Override
public boolean dispatchKeyEvent(KeyEvent event)
{
    if (event.getKeyCode() == KeyEvent.KEYCODE_BACK)
    {
        // handle back press
        // if (event.getAction() == KeyEvent.ACTION_DOWN)
        return true;
    }
    return super.dispatchKeyEvent(event);
}
