Geofencing

[ashbash0697]

Hi, I am using the example code of geofencing, it does not seem to work the broadcast receiver is not being called, I've tried many solutions nothing seems to work

[RonaldSalazarH]

Hi, I have the same problem and change the Lines: 233 and 236 in MainActivity.java:

Intent intent = new Intent(getApplicationContext(), GeofenceBroadcastRutaReceiver.class); // We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when calling // addGeofences() and removeGeofences(). mGeofencePendingIntent = PendingIntent.getBroadcast(mContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

========== Context mContext; @Override protected void onCreate(Bundle savedInstanceState) { mContext = this; }

Please tell me the best solution for Geofencing. I use a ForeGroundService with a notification on Top instead of the IntentService as it wasnt working. and have a PendingIntent to receive the entry/exit events . But still My geofencing solution doesnt work at all.

[DevEddy]

Same thing here, geofencing doesn't trigger when the app is closed. Geofencing only works with foreground service.

Would be great it someone at google could make a statement.

@pramodit do you use the BroadcastReceiver like in the sample?

[pramodit]

Now it works fine for me . I used a JobScheduler and scheduling the job every now and then as this background thread gets killed in Android Oreo due to Background Execution Limits . @DevEddy Please try with the JobService . It worked like a charm to me

[DevEddy]

Hi @pramodit I am glad that it works for you now.

Could you provide some snippets how you're doing this? I would be very thankful.

[pramodit]

Sure @DevEddy This is how i am doing it . I use this JobService and reschedule it every 1 secs in Android O to make sure the OS dont kill my service. /**

[rameshsambu-dev]

Can you share the working sample if its possible?I am trying for this solution last one week

[kraghu]

@pramodit Does your solution still work ? I have tried everything at this point

[pramodit]

Yes it still works like a charm for me @kraghu

[pramodit]

If you want it to make it optimised for every other locations , you could use a WorkManager which is compatabile for all regions such as for china, where there are no GooglePlayServices , it uses FirebaseDispatcher, AlarmManager for some devices and JobScheduler wherever necessary @kraghu :)

@pramodit why you create geofences every time in service MyApplication.getInstance().createGeoFences(fencesList); Because Android Oreo and above doesn't provide frequent location update, Don't we need to call location update service in the background? I am confused :(

[pramodit]

@RameshPokharel Hey am not creating the fences its just named that way. i am just registering them once for all . i get the fences from an API call and then i use them. if it's already created then i don't recreate the fences
