I am trying to display a TextView at the top left corner of Google Maps that inform users if they are x distances from particular marker point locations, i.e. "You are close to location A", but only display the TextView if within range. If they move out of range, the TextView will disappear. I understand that the Google Places API shows you all the nearby locations, but I only want to show nearby locations of the markers I have on the map if users are x distances close to them. How can I achieve this? Would I still need to use Google Places API? my class .java: private GoogleMap mMap; private

I’m porting an iOS app to Android, and using Google Maps Android API v2. The application needs to draw a heatmap overlay onto the map. So far, it looks like the best option is to use a TileOverlay and implement a custom TileProvider . In the method getTile , my method is given x, y, and zoom, and needs to return a bitmap in the form of a Tile . So far, so good. I have an array of heatmap items that I will use to draw radial gradients onto the bitmap, each with a lat/long. I am having trouble with the following two tasks: How do I determine if the tile represented by x, y, and zoom contains the

I am going to share a solution of moving a marker along the path if you have List.The Bitmap will move along the path from using LatLng list. public static void setAnimation(GoogleMap myMap, final List<LatLng> directionPoint, final Bitmap bitmap) { Marker marker = myMap.addMarker(new MarkerOptions() .icon(BitmapDescriptorFactory.fromBitmap(bitmap)) .position(directionPoint.get(0)) .flat(true)); myMap.animateCamera(CameraUpdateFactory.newLatLngZoom(directionPoint.get(0), 10)); animateMarker(myMap, marker, directionPoint, false); } private static void animateMarker(GoogleMap myMap, final Marker

I need to do the following: I have a Marker on the map and I need to change the position of it. So I tried the following: MarkerOptions a = new MarkerOptions() .position(new LatLng(50,6))); map.addMarker(a); a.position(new LatLng(50,5)); where map is a GoogleMap . I think I have to refresh the map or somthing equal? Found the solution, Need to do it like this: MarkerOptions a = new MarkerOptions() .position(new LatLng(50,6))); Marker m = map.addMarker(a); m.setPosition(new LatLng(50,5)); There's one example of moving marker in google map v2 demo app ..

I am using com.google.android.gms:play-services-maps:7.5.0 version of Google Maps services. When trying to call the below I get java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.android.gms.maps.SupportMapFragment.getMapAsync(com.google.android.gms.maps.OnMapReadyCallback)' on a null object reference . @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { SupportMapFragment mapFragment = (SupportMapFragment) getActivity().getSupportFragmentManager() .findFragmentById(R.id.map); mapFragment.getMapAsync(this)

I've got a UI that has a MapFragment with a transparent View overlaid on top of it. The map takes up the entire screen, whereas the View is just the left third of the screen. As a result, the default "center" of the map is off. When someone clicks on a marker, I want to center that marker in the wholly visible area of the MapFragment (not the center of the MapFragment itself). Since this is hard to describe with words, let me use a few pictures. Suppose this is how my UI looks: When the user clicks a marker, I want to both center it and zoom in to see it closer. Without any adjustments, this

I have googleMap (v2) with polyline that presents a route between the user current location and the destination point. Now, I want to update the polyline according to the user moving. I tried to redrawing the whole polyline when location is changed but the polyline is flickering. I didn't find any appropriate function in the PolylineOptions class (the function add() is only to add a vertex but not to update or remove) do you have any idea how to update the polyline ??? thank you for giving your time. The only way as of version 3.1.36: List<LatLng> points = polyline.getPoints(); points.add
