android-mapview

I've seen some topics some months ago, about the fact that using (Google)MapView inside a Fragment was a bit tricky/impossible. I would like to know if atm (June) there is a workaround ? My application (Android 3.0) is essentially working with the Fragment system and I need to display a map in one of these fragments. Currently I only know of one solution. I stumbled across this when I ran into the same problem. https://github.com/petedoyle/android-support-v4-googlemaps . EDIT Here is a newer fork based off r9 https://github.com/rfc1459/android-support-v4-googlemaps You can build it via eclipse

How can i calculate delta-latitude and delta-longitude values form latitude and longitude values for MapView component in React-Native. Thank You If you have an array of coordinates and you want a region that will fit all these points, you can do something like this: const regionContainingPoints = points => { let minLat, maxLat, minLng, maxLng; // init first point (point => { minLat = point.latitude; maxLat = point.latitude; minLng = point.longitude; maxLng = point.longitude; })(points[0]); // calculate rect points.forEach(point => { minLat = Math.min(minLat, point.latitude); maxLat = Math.max

I'm currently adding annotations to my map through a loop... but the annotations are only appearing on my map in groups. Also, on load, only about 4 annotations are actually displayed on the map... but as I move the map a little, all of the annotations that should be there, suddenly appear. How can I get all of the annotations to load in the right place, one at a time? Thanks in advance! Here is the code I'm using to add annotations: NSString *incident; for (incident in weekFeed) { NSString *finalCoordinates = [[NSString alloc] initWithFormat:@"%@", [incident valueForKey:@"coordinates"]];

I am implementing a map navigation application. I get device's current location every 1000 milliseconds and draw a polyline, from the current location to fixed marker point. But when using device inside a vehicle, polyline and current location update not animating like uber or google-map. It's changing suddenly from one point to another. How to get a smooth animation of the current location change. you have to try this way it will help you private void animateMarkerNew(final LatLng startPosition, final LatLng destination, final Marker marker) { if (marker != null) { final LatLng endPosition =

I have code that takes a title and an address of a location,then get coordinates from google maps csv, then add annotation. It works, but when I want to add 50 or more annotation at once it freezes for about 30-40 seconds and then displays annotations, so what I want to know is did I screw up memory management and that's why it's so slow, or something else? Can I speed it up? Here is the code: - (void) addAnnotation: (NSString*) annoTitle: (NSString*) annoAddress { NSString *address = annoAddress; NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output

Is there any common way to implement marker clusters for Google Maps in Android apps? I have a database of about 10,000 locations and would like to display them in more intelligent ways than just dumping thousands of markers on a display that's rarely larger than a match box... Ideally, it should be possible to retrieve the markers from a website URL, though I'm not sure if using the usual Async functions for that even makes sense from a usability point of view. Clusterkraf would work for you. One of the options in Advanced Mode in the sample app is to cluster 10,000 random points worldwide.
