For countless hours, I have been trying to get the user's current location upon launching my app, but then every approach I have tried has returned null.
My instantiation of the GoogleApiClient takes place in "onCreate"
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EventBus.getDefault().register(this);
FirebaseMessagingHelper.registerDevice(this, FirebaseInstanceId.getInstance().getToken());
activity = this;
//xaxaxa
driverMapView = (MapView) findViewById(R.id.googleMapObject);
driverMapView.onCreate(savedInstanceState);
driverMapView.getMapAsync(this);
getUserToEnableCameraUsage();
if (googleApiClient == null)
{
googleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
googleApiClient.connect();
Here is the code in my project (extremely similar to the code provided in the api's tutorial:
@Override
public void onConnected(@Nullable Bundle bundle)
{
int LOCATION_ALLOWED = ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION);
if (LOCATION_ALLOWED != PackageManager.PERMISSION_GRANTED)
{
lastLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
if (lastLocation != null)
{
driverGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(lastLocation.getLatitude(), lastLocation.getLongitude()), 16));
testHelper.setDriverLatLngLocation(new LatLng(lastLocation.getLatitude(), lastLocation.getLongitude()));
}
}
}
protected void createLocationRequest()
{
locationRequest = new LocationRequest();
locationRequest.setInterval(1000);
locationRequest.setFastestInterval(500);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder locationSettingsRequestBuilder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
PendingResult<LocationSettingsResult> pendingResult = LocationServices
.SettingsApi
.checkLocationSettings(googleApiClient, locationSettingsRequestBuilder.build());
pendingResult.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(@NonNull LocationSettingsResult locationSettingsResult)
{
Status result = locationSettingsResult.getStatus();
if (result.getStatusCode() == LocationSettingsStatusCodes.SUCCESS)
{
requestingLocationUpdates = true;
startLocationUpdates();
Toast.makeText(MainActivity.this, "Gucci", Toast.LENGTH_SHORT).show();
}
if (result.getStatusCode() == LocationSettingsStatusCodes.RESOLUTION_REQUIRED)
{
requestingLocationUpdates = false;
Toast.makeText(MainActivity.this, "Please enable location services", Toast.LENGTH_SHORT).show();
}
if (result.getStatusCode() == LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE)
{
requestingLocationUpdates = false;
Toast.makeText(MainActivity.this, "App cannot access settings", Toast.LENGTH_SHORT).show();
}
}
});
}
protected void startLocationUpdates()
{
int LOCATION_ALLOWED = ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION);
if (LOCATION_ALLOWED != PackageManager.PERMISSION_GRANTED)
{
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, this);
}
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult)
{
}
@Override
public void onLocationChanged(Location location)
{
driverGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 16));
testHelper.setDriverLatLngLocation(new LatLng(location.getLatitude(), location.getLongitude()));
Toast.makeText(MainActivity.this, "It's working", Toast.LENGTH_SHORT).show();
}
protected void stopLocationUpdates()
{
LocationServices.FusedLocationApi.removeLocationUpdates(
googleApiClient, this);
requestingLocationUpdates = false;
}
I instantiate "createLocationRequest here:
public void onMapReady(GoogleMap googleMap)
{
//Setting map starts here
int LOCATION_ALLOWED = ContextCompat.checkSelfPermission(this.getApplicationContext(), Manifest.permission.ACCESS_COARSE_LOCATION);
if (LOCATION_ALLOWED == PackageManager.PERMISSION_GRANTED)
{
googleMap.setMyLocationEnabled(true);
}
createLocationRequest();
The instantiation of "createLocationRequest()" takes place before the block of code that needs it and it is null?
I have looked over multiple solutions, but they've all not helped me. I was hoping that maybe someone could help me out as this has been really bothering me and has halted the development of my app.
