Update GeoNotificationManager.java
Update GeoNotificationManager.java

When one adds some geofences and then removes all of them, upon every device reboot, the app crashes because the AddGeofenceCommand can't be called with geoFences list being empty. The exact error is "java.lang.IllegalArgumentException: At least one geofence must be specified."
