due to it is Admob cause the crash, it is probably not possible for AppYet to fix it.
do you know how to use "adb logcat", if you are Android Developer, then you can help us by getting into the system log to see why app crashed.
the log doesn't show the cause of crash.Used an error filter on log, I attached only the logcat during the app crash (app name : com.stiri.turda)
