UserLocation Problems

[viciopoli01]

I'm trying to get the user location using LocationEngine on Android devices , but when I star the app the usser's marker is located in (0.0, 0.0) and never update it's location.
How is it possible?

I try to replicate the example https://www.mapbox.com/android-docs/plugins/overview/location-layer/

`
private void enableLocationPlugin() {

    // Check if permissions are enabled and if not request
    if (PermissionsManager.areLocationPermissionsGranted(this)) {

        // Create an instance of LOST location engine
        initializeLocationEngine();
        LocationLayerOptions options = LocationLayerOptions.builder(this)
                .build();
        locationLayerPlugin = new LocationLayerPlugin(mapView, mapboxMap, locationEngine, options);
        locationLayerPlugin.setRenderMode(RenderMode.COMPASS);
        locationLayerPlugin.setCameraMode(CameraMode.TRACKING);
        locationLayerPlugin.setLocationLayerEnabled(true);
    } else {
        permissionsManager = new PermissionsManager(this);
        permissionsManager.requestLocationPermissions(this);
    }
}


private void initializeLocationEngine() {
    locationEngine = new LocationEngineProvider(this).obtainBestLocationEngineAvailable();
    locationEngine.setPriority(LocationEnginePriority.HIGH_ACCURACY);
    locationEngine.setInterval(1000);
    locationEngine.setFastestInterval(500);
    locationEngine.addLocationEngineListener(this);
    locationEngine.activate();
    locationEngine.requestLocationUpdates();

    
    Location lastLocation = locationEngine.getLastLocation();
    if (lastLocation != null) {
        setCameraPosition(lastLocation);
        locationEngine.addLocationEngineListener(this);
    } else {
        locationEngine.addLocationEngineListener(this);
    }
}

`
I'm using this version of MapBox in grandle

implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-building:0.2.0' implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation:0.12.0' implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-locationlayer:0.5.2'

I responded to your same question on Stack Overflow but will also put my response here:

Few notes about your code snippet.

LocationLayerOptions options = LocationLayerOptions.builder(this)
                .build();

isn't needed since you aren't actually changing any options.

locationLayerPlugin.setLocationLayerEnabled(true);

Isn't needed since you are calling setRenderMode right above which automatically enables it

The issue with seeing the user location at nullisland (0.0, 0.0) has been reported already in #460.

For the location updates, it looks like you are attaching a listener. are you receiving updates in that listener and the Location Layers just not updating or are you not receiving any updates at all? If the latter, it's an issue more likely with the locationEngine and not the Location Layer Plugin.

I Have the same issue. In my case only onConnected() is called and onLocationChanged() is never called

[diklimchuk]

I've found what my issue was after looking at LocationLayerModesActivity.java. I was missing locationEngine.requestLocationUpdates() in onConnected(). It's weird that LocationLayerMapChangeActivity.java doesn't do that which lead to my mystake since i've been following it. Is this indended?

[viciopoli01]

@cammace I have both the problems, the LocationLayer doesn't update and also I don't receive location update.

@diklimchuk, thanks for pointing out that issue in the LocationLayerModesActivity, I've opened #524 to fix this issue in the testapp. @viciopoli01 it's probably the same issue @diklimchuk was running into, can you ensure you are manually adding a listener and requesting location updates inside the onConnected method?

It seems to work, with a dealy on getting position at the start, but it works now.
