Unfortunately , Android app has stopped. Logcat included.

Hello, my android application shows the "Unfortunately app has stopped" error when I transition from one scene to the next. Here is the last part of my logcat file where I believe the error occurs. I'm not sure what the problem is though. Your help will be appreciated, thanks.
