I am drawing a plain color PolyLine on my map the following way, and it works great: PolylineOptions polyLine = new PolylineOptions(); polyLine.width(5); polyLine.color(Color.RED); polyLine.geodesic(true); for (int i = 0; i < speed.length; i++) { polyLine.add(new LatLng(lat, lng)); } map.addPolyline(polyLine); Now I would want to draw a polyline with different colors between different points, depending on the speed between those two points. There doesn't seem to be an easy way of doing it. I am referring to this question : draw polylines with different colors on v2 maps , and I can add

I'm working on an application that displays the location of moving items on a Google MapView. I need a way to update the position of the icons that represent the items (as well as change the facing of the icons every two seconds as updated data comes in). I currently have an activity in the app that extends MapActivity. On to this I have overlaid a static Overlay that draws some lines on the map and an ItemizedOverlay that draws a static icon. There is a draw() method that claims to be used by animated overlays, but overriding it to do my animations still doesn't make anything animate. Do I

I have map view in my fragment. I need to refresh map and add different markers based on condition. So, I should remove last markers from map before add new markers. Actually, some weeks ago app was working fine and suddenly it happened. My code is like this: private void displayData(final List<Venue> venueList) { // Removes all markers, overlays, and polylines from the map. googleMap.clear(); . . . } Last time it was working fine (before new Google Map API announce by Android team in I/O 2013). However, after that I adapted my code to use this new API. Now, I don't know why this method

Is there a way to always show the zoom controls on a MapView? I have added the zoom controls using map=(MapView)findViewById(R.id.map); map.setBuiltInZoomControls(true); but the zoom controls fade in and out. I want them to always be visible. Solved this by putting my own ZoomControls in my layout xml: <ZoomControls android:id="@+id/zoomcontrols" android:layout_width="wrap_content" android:layout_height="wrap_content" /> and then setting up onClickListeners for then to handle the zoom: zoomControls = (ZoomControls) findViewById(R.id.zoomcontrols); zoomControls.setOnZoomInClickListener(new View

I'm developing an Android app that uses Osmdroid to display the maps in offline mode. I have an issue when I want to zoom in or out by pinching on the map or using the build-in zoomcontrols. When I zoom in the map tiles are not always correctly rendered and when I zoom out the sometimes there are some gray tiles in the map, sometimes everything is rendered OK. It's not related on the location displayed on the map. My map tiles are stored in an osmdroid zip-file with the Mapnik source in the folder /mnt/sdcard/osmdroid. I'm using osmdroid-3.0.7. So, any help is welcome. See my code below (my
