Hi !I am developing an app similar to transparent screen, you can find it on market. I managed to make an overlay with a layout that contains a surfaceview over all the other activities(menu, screen, icons) and I want to make the camera preview transparent, I used TYPE_SYSTEM_OVERLAY on the WindowManager.LayoutParams so I can interact with the phone, I want to make a transparent screen type application. But I don't know how to make the camera preview transparent. Any advice?
