Location layer doesn't display current location immediately. #424
Description
First off, thanks for the great work with the SDK and plugins.
Currently I'm running into this one problem trying to get user location to work. Basically, the Location Layer plugin doesn't immediately display the current location of user.
Sometimes you can force the location display by going out of the application and going in again, and sometimes you can just wait a bit for it to appear on the screen.
The behavior can be seen in this gif here.
Here is my setup function:
private void setupMapView() {
mapView.getMapAsync(new OnMapReadyCallback() {
@Override
public void onMapReady(final MapboxMap mapboxMap) {
if (PermissionsManager.areLocationPermissionsGranted(MainActivity.this)) {
locationEngine = new LocationEngineProvider(MainActivity.this).obtainLocationEngineBy(LocationEngine.Type.ANDROID);
locationEngine.setPriority(LocationEnginePriority.HIGH_ACCURACY);
locationEngine.addLocationEngineListener(new LocationEngineListener() {
@Override
public void onConnected() {
locationEngine.requestLocationUpdates();
}
@Override
public void onLocationChanged(Location location) {
setCameraPosition(mapboxMap, location);
locationEngine.removeLocationEngineListener(this);
}
});
locationEngine.activate();
locationPlugin = new LocationLayerPlugin(mapView, mapboxMap, locationEngine);
}
mapboxMap.getUiSettings().setCompassEnabled(false);
mapboxMap.getUiSettings().setRotateGesturesEnabled(false);
mapboxMap.getUiSettings().setTiltGesturesEnabled(false);
}
});
}
private void setCameraPosition(MapboxMap map, Location location) {
map.animateCamera(CameraUpdateFactory.newLatLngZoom(
new LatLng(location.getLatitude(), location.getLongitude()), 13));
}
@Override
@SuppressWarnings({"MissingPermission"})
protected void onStart() {
super.onStart();
if (locationEngine != null) {
locationEngine.requestLocationUpdates();
}
if (locationPlugin != null) {
locationPlugin.onStart();
}
mapView.onStart();
}
@Override
protected void onStop() {
super.onStop();
if (locationEngine != null) {
locationEngine.removeLocationUpdates();
}
if (locationPlugin != null) {
locationPlugin.onStop();
}
mapView.onStop();
}
