is it possible to share screen of the application with wowza?
No, not with the GoCoder SDK @Ata Alla, it only accesses the camera on the phone and not the screen. Your other option since we are no longer going to supporting the GoCoder SDK after Jan 5, 2021, is to use WebRTC with android chrome browser where you can share your screen, but be warned there is no audio when you share the screen from a phone.
