I see, then I would have to use one SurfaceView for the first activity and a GLSurfaceView for the other activity. I searched for information about how to switch between 2 activities on the forum and found one of your threads:
http://groups.google.com/group/android-developers/browse_thread/thread/c6ffe95d4909167b/fd1be2b4a1912c1a?lnk=gst&q=switch+between+activities#fd1be2b4a1912c1a You recommend using a viewflipper here, so I can not use that approach. I found another thread http://groups.google.com/group/android-developers/browse_thread/thread/e17375dd36d0cdc6/eb66078f6325c77c?lnk=gst&q=switch+between+activities#eb66078f6325c77c where they used the StartActivityForResult method. How would you recommend that I should swith between the activites without using a ViewFlipper?
