Running Geofence app on android emulator

Question

Is there a way to run the sample Geofence app provided on the Android emulator: http://developer.android.com/training/location/geofencing.html

The app shuts down on initiation and I get these error messages on LogCat:

Answer 1

Seems like your MainActivity can't be found. Maybe you do not have it mentioned in your Manifest.xml file?

Besides that: there is actually no point in getting the geofencing App to run in the emulator. Androids Geofencing API is heavily based on network positioning and the emulator just supports GPS. So even though you could make the App run on the emulator creating geofences would fail with other exceptions.
