I have two classes mainly MainActivity.java and GeofenceTransitionIntentService.java class that extends IntentService. This class is unreachable. I have tried to call this class by using intent from MainActivity.java class but couldn't able to invoke GeofenceTransitionIntentService class.Please help me in this.
