[Java for Android App Development] stud91:
Unfortunately, i donot have an Android device on hand. I was trying to run the sample Geofencing app provided on Android Developer.

However, the app crashes as soon as it is initiated. The emulator details are (PLATFORM = Android 4.4.2, API = 19, CPU = ARM)

I get this LogCat error:
