Android and Unity - creating a transparent Activity

Question

Hi,

I'm developing an app that uses Unity in Android.
I start one activity from another (with start activity for result) and want it to be transparent, so that I can perform gestures on the activity on top, but be able to see the one underneath.

In Android I managed to do this by adding a style to my manifest, which makes the activity transparent, however, when using the same thing in Unity, the result is that I have a black screen.

Please advise on how to make a transparent activity work on top of another one.

Thanks in advance. Apapus.

Unity Engine purposefully adds DimAmount to the Window when a new activity is created, So we need to make it transparent after the onCreate of the activity.

For example,

 protected void onCreate(Bundle savedInstanceState) {
     Window window = getWindow();
     window.setDimAmount(0); //Making the window dim transparent
     window.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
 }
