newuser Did you run "rake clean:android" command? I can't reproduce this issue on my sight after that bugfix. Maybe you have some other versions of Rhodes gem? Try to build it using the repository. Just switch to the branch, I send earlier, copy rhobuild.yml from gems folder to the folder with code from the repository and change SDK variable in the application build.yml and just rebuild the app. Please, check it.
I have done an android build after running the clean command, it does seem to be ok on Android now. Testing on iOS (again, after the clean command) and I'm still able to make it crash just by opening the camera and pressing cancel to come out of it as well as by actually taking pictures. This is on an iPad mini 2 after ~100 camera opens/closes.
