Answer 1

I was able to make this work with the following code in my transparent foreground activity

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Pass touch events to the background activity
        getWindow().addFlags(
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
                        | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL
                        | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
...
        setContentView(R.layout.main);
}
