I'm trying to implement Marshmallow's permission support, but my code inside "onRequestPermissionsResult" is never called. The "onCreate" and "onMapReady" parts of the code work fine. Checking if the device has the permission and requesting the permission works fine. I'm using an Nexus 5X emulator running Android Marshmallow 6.0, API 23. I have tried to do what it's mentioned here -> Android M Permissions: onRequestPermissionsResult() not being called But I cannot get it to work, it doesn't matter if I use "ActivityCompat.requestPermissions" or directly "requestPermissions", it nevers get

I'm trying to achieve similar to how navigation in google maps works, check the below image for reference. In google maps, the marker looks to be at a static location except the camera is changing . To achieve this I animate the marker every time my location changes and later I position it towards the bottom of the screen by panning it by -300px in Y coordinate. But I cannot animate the camera for change in location an moving the screen 300px down at the same time. When I animate the camera for change in location the marker moves exactly to the centre of the screen and later when I move the

I have a page with a single form on it. The form contains a text box and a submit button. When the form is submitted, either by clicking the button, or by pressing enter in the textbox, I want to do a lookup (in this case, geocoding a postcode using Bing Maps), and then submit the form to the server, as usual. My current approach is to add a handler for the submit event to the one-and-only form, and then call submit() when I've finished, but I can't get this to work, and haven't been able to debug the problem: $(document).ready(function () { $("form").submit(function (event) { var postcode = $

I've been searching for quite sometime an answer to my problem with no success. So here it goes... KMLViewer, Apple's example is not working in some cases. After executing the README steps, i've tried to build up a route between Lisboa, Portugal and Porto, Portugal. And here the strangest thing happens. The annotations are built correctly, although the overlay (MKPolyline) does not, it only draws part of the route and it starts drawing in the middle of an "annotation". What am i missing ? You can try, Madrid - Barcelona, you have also the same issue. Thanks in advance for spending sometime in

Why is this coming? i use eclipse and in that use the "export signed application" option. I use the existing keystore i.e. debug.keystore. I've got my own api key dev key, and have used it at all the proper places. The cross marks dont come all the time, but they do come often enough to look for a solution! remove the setSatellite() and setStreetView() methods from ur activity class if hv included them. that seems to be a bug in the mapView.

Given a longitude and latitude not my current location how can I perform a reverse geocode lookup using GLGeocoder ? self.geoCoder = [[CLGeocoder alloc] init]; self.locationManager = [[CLLocationManager alloc] init]; self.locationManager.delegate = self; // [self.locationManager startUpdatingLocation]; [self.geoCoder reverseGeocodeLocation: locationManager.location completionHandler: ^(NSArray *placemarks, NSError *error) { // [self.locationManager stopUpdatingLocation]; CLPlacemark *placemark = [placemarks objectAtIndex:0]; // Long address // NSString *locatedAt = [[placemark
