FusedLocationProviderApi Fatal exception: GoogleApiClient is not connected yet.

Question

I am a newbie android developer. I want to make a some GoogleMaps app which will show some location around user current location. But I haven't captured user location. I looked too many docs, GoogleMap Tutorials from Google. Searched from stackoverflow, but I couldn't find any solution.

There is my HaritaFragment.java

There is the logcat output :

What is the problem ? I tried 4.0.1 real HTC devices and 4.4.4 GenyMotion with GooglePlayServices.

I want to get user near locations from Parse.com and I have to capture user location for this method:

if (userLocation != null) {

            ParseGeoPoint parsedLocation = (new ParseGeoPoint(userLocation.getLatitude(), userLocation.getLongitude()));
            ParseQuery<ParseObject> query = ParseQuery.getQuery("Vets");
            query.fromLocalDatastore();
            query.whereNear("location", parsedLocation);
            //query.whereWithinKilometers("location",userLocation,100);
            query.setLimit(250);
            query.findInBackground(new FindCallback<ParseObject>() {
                @Override
                public void done(List<ParseObject> list, ParseException e) {

                    if (e == null) {



                    } else {

                        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                        builder.setTitle(getString(R.string.parse_online_query_error_title));
                        builder.setMessage(getString(R.string.parse_online_query_error_message));
                        builder.setPositiveButton(android.R.string.ok, null);
                        AlertDialog dialog = builder.create();
                        dialog.show();
                    }
                }
            });
        } 

If you show me the another way to do this. It would be good for me. I will not insistence for FusedLocationProviderApi.

Thank you !

Answer 1

It looks like you've just got things in the wrong order. It's important to know the order Android takes when starting, pausing and resuming activities.

http://developer.android.com/training/basics/activity-lifecycle/pausing.html

The problem in your code is when you hit onResume the mGoogleApiClient could have not quite connected.

This is the order you should have

1. Create mGoogleApiClient
2. Call mGoogleApiClient.connect();
3. onConnected() gets called automatically.

-- Call startLocationUpdates() from inside onConnected

Doing the above means your Api client is always connected when you request location updates.

I think the quickest way to fix your code is delete your onPause and onResume methods and un-comment the onDisconnect in onStop.

Allow onStart and onStop to handle your connection and the connection in turn to handle the location updates.

Best of luck.
