I am reading through documentation from here.

https://developer.android.com/training/location/geofencing

It can update me location for my geofence when I run that service. Problem is I need to monitor continuously. So, I am thinking to do timer in my service and check my geofence regularly. But, I think it will definitely drain battery.

I don't want to monitor location and instead, I need android OS to update me whether user goes inside my geofence just like iOS. Is there any way to implement that ?

public class GeofenceTransitionsIntentService extends IntentService {

    // ...

    protected void onHandleIntent(Intent intent) {

        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);

        if (geofencingEvent.hasError()) {

            String errorMessage = GeofenceErrorMessages.getErrorString(this,

                    geofencingEvent.getErrorCode());

            Log.e(TAG, errorMessage);

            return;

        }



        // Get the transition type.

        int geofenceTransition = geofencingEvent.getGeofenceTransition();



        // Test that the reported transition was of interest.

        if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER ||

                geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {



            // Get the geofences that were triggered. A single event can trigger

            // multiple geofences.

            List<Geofence> triggeringGeofences = geofencingEvent.getTriggeringGeofences();



            // Get the transition details as a String.

            String geofenceTransitionDetails = getGeofenceTransitionDetails(

                    this,

                    geofenceTransition,

                    triggeringGeofences

            );



            // Send notification and log the transition details.

            sendNotification(geofenceTransitionDetails);

            Log.i(TAG, geofenceTransitionDetails);

        } else {

            // Log the error.

            Log.e(TAG, getString(R.string.geofence_transition_invalid_type,

                    geofenceTransition));

        }

    }
