I'm using android device's native Geofence service. Here are implementation details:

Tracked transition type: ENTER

Range: 500 meters (1640 feet)

Notification responsive time: 500ms

Added Geofence count: 15-20

Initial trigger (setInitialTrigger()): Not set

Location accuracy on device: High

Location permissions: FINE LOCATION and COARSE LOCATION

Location service on device: ON

Location permission to app: Yes

Android Oreo support: Yes (Used Broadcast receiver and JobIntentService)

Issues:

1. On some device, same notification is triggering again and again when
   user is moving withing same geofence.


2. On some device, some notifications are triggering some are not.


3. On some device, no geofence in triggering at all.

Shall I move to third-party geofence services? If yes, could you please suggest any good service at this?

Creating goefence:

Let me show you what i have done for a similar task. Below code has been used to achieve geofencing.

class LocationService : Service(), GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks {



var mLocationManager: LocationManager? = null

var googleApiClient: GoogleApiClient? = null

var pendingIntent: PendingIntent? = null

var geofencingRequest: GeofencingRequest? = null

var mGeofenceList: ArrayList<Geofence>? = null



private inner class LocationListener(provider: String) : android.location.LocationListener {

    private var mLastLocation: Location = Location(provider)



    override fun onLocationChanged(location: Location) {

        mLastLocation.set(location)

    }



    override fun onProviderDisabled(provider: String) {}



    override fun onProviderEnabled(provider: String) {}



    override fun onStatusChanged(provider: String, status: Int, extras: Bundle) {}

}



internal var mLocationListeners = arrayOf<android.location.LocationListener>(LocationListener(LocationManager.GPS_PROVIDER), LocationListener(LocationManager.NETWORK_PROVIDER))





override fun onBind(arg0: Intent): IBinder? {

    return null

}



override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {

    mGeofenceList = ArrayList()

    populateGeofenceList()

    super.onStartCommand(intent, flags, startId)

    return Service.START_STICKY

}



override fun onCreate() {

    initializeLocationManager()

    try {

        mLocationManager!!.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, Constant.LOCATION_INTERVAL.toLong(), Constant.LOCATION_DISTANCE, mLocationListeners[1])

    } catch (ex: java.lang.SecurityException) {

    }



}



override fun onDestroy() {

    super.onDestroy()

    if (mLocationManager != null) {

        for (i in mLocationListeners.indices) {

            try {

            } catch (ex: Exception) {

                ex.printStackTrace()

            }

        }

    }

}



private fun initializeLocationManager() {



    googleApiClient = GoogleApiClient.Builder(this)

            .addApi(LocationServices.API)

            .addConnectionCallbacks(this)

    googleApiClient!!.connect()

    if (mLocationManager == null) {

        mLocationManager = applicationContext.getSystemService(Context.LOCATION_SERVICE) as LocationManager?

    }

}

        LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, object : com.google.android.gms.location.LocationListener {

            override fun onLocationChanged(location: Location) {

                DashBoardActivity.latitude = location.latitude

                DashBoardActivity.longitude = location.longitude

                if (BuildConfig.DEBUG) {

                    Log.e("LocationChanged:", location.latitude.toString() + " ," + location.longitude)

                }

            }

        })

    } catch (e: SecurityException) {

        e.printStackTrace()

    }

}



private fun startGeofencing() {

    pendingIntent = getGeofencePendingIntent()

    geofencingRequest = GeofencingRequest.Builder()

            .setInitialTrigger(Geofence.GEOFENCE_TRANSITION_ENTER)

            .addGeofences(mGeofenceList)

            .build()



    if (googleApiClient?.isConnected!!) {

        try {

            LocationServices.GeofencingApi.addGeofences(googleApiClient, geofencingRequest, pendingIntent).setResultCallback(object : ResultCallback<Status> {

                override fun onResult(status: Status) {

                .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER or Geofence.GEOFENCE_TRANSITION_EXIT)

                .build())

    }

}



private fun getGeofencePendingIntent(): PendingIntent? {

    if (pendingIntent != null) {

        return pendingIntent

    }

    val intent = Intent(this, GeofenceRegistrationService::class.java)

    pendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)

    return pendingIntent

}



override fun onConnected(bundle: Bundle?) {

    startGeofencing()

    startLocationMonitor()

}



override fun onConnectionSuspended(i: Int) {}



override fun onConnectionFailed(connectionResult: ConnectionResult) {}

}

For getting the geofence events, i have used below code:

class GeofenceRegistrationService : IntentService("GeoIntentService") {



val TAG = "GeoIntentService"

var mGeofencList: ArrayList<Geofence>? = null



override fun onHandleIntent(intent: Intent?) {

    mGeofencList = ArrayList()

    val geofencingEvent = GeofencingEvent.fromIntent(intent)

    if (geofencingEvent.hasError()) {

        if (BuildConfig.DEBUG) {

            Log.d(TAG, "Error" + geofencingEvent.errorCode)

        }

    } else {

        try {

            val transaction = geofencingEvent.geofenceTransition

            val geofences = geofencingEvent.triggeringGeofences

            for (i in 0 until geofences.size) {

                mGeofencList?.add(geofences[i])

            }

            if (transaction == Geofence.GEOFENCE_TRANSITION_ENTER) {

                sendBroadCast(true)

                if (BuildConfig.DEBUG) {

                    Log.d(TAG, "You are inside Geofenced area")

                }

            }

            if (transaction == Geofence.GEOFENCE_TRANSITION_EXIT) {

                sendBroadCast(false)

                if (BuildConfig.DEBUG) {

                    Log.d(TAG, "You are outside Geofenced area")

                }

            }

        } catch (e: Exception) {

            e.printStackTrace()

        }



    }

}



private fun sendBroadCast(isInside: Boolean) {

    val broadCastIntent = Intent(Constant.SRI_GEO_FENCE)

    broadCastIntent.putExtra(Constant.KEY_GEOFENCE_STATE, isInside)

    broadCastIntent.putExtra(Constant.KEY_GEOFENCE_LIST, mGeofencList)

    LocalBroadcastManager.getInstance(this).sendBroadcast(broadCastIntent)

}

}

Then you just have to start the LocationService as follows:

 val locationIntent = Intent(activity, LocationService::class.java)

                    activity.startService(locationIntent)

It has been tested and working perfectly. If there is any question, please approach me.
Thanks
