Find distance between two points on map using Google Map API V2

Question

I am using google map api v2 in my android application  I am able to show the map and put markers on it  but now I am stuck with the  problem in which I need to find out the distance between two markers or points placed on map  I have already gone through the  docs but didn t find anything helpful in this case   If anyone knows how to solve this then please help me   Thanks

You should use the android Location  You can do   location1 distanceTo location2     And also   float   results   new float 1   Location distanceBetween latLongA latitude  latLongA longitude                           latLongB latitude  latLongB longitude                           results     And you will get the distance in meters between location1 and location2 in meters  And beetween latLongA ant latLongB   Using location

Coming rather late  but seeing that this is one of the top results on Google search for the topic I ll share another way   Use a one-liner with Googles utility class SphericalUtil  SphericalUtil computeDistanceBetween latLngFrom  latLngTo    You will need the utility classes   You can simply include them in your project using gradle   implementation  com google maps android android-maps-utils 0 5

to get distance between two points try this code    public static float GetDistanceFromCurrentPosition double lat1 double lng1  double lat2  double lng2             double earthRadius   3958 75           double dLat   Math toRadians lat2 - lat1            double dLng   Math toRadians lng2 - lng1            double a   Math sin dLat   2    Math sin dLat   2                    Math cos Math toRadians lat1                     Math cos Math toRadians lat2     Math sin dLng   2                    Math sin dLng   2            double c   2   Math atan2 Math sqrt a   Math sqrt 1 - a             double dist   earthRadius   c           int meterConversion   1609           return new Float dist   meterConversion  floatValue

This is an old question with old answers  I want to highlight an updated way of calculating distance between two points  By now we should be familiar with the utility class   SphericalUtil   You can retrieve the distance using that   double distance   SphericalUtil computeDistanceBetween origin  dest

In android google maps application there is a very easy way to find distance between 2 locations  to do so follow the following easy steps         when you first open the app go to   your timeline   from the drop menue on the top left  once the new windwo opens  chose from the settings on your top right menue and choose  add place       add your places and name them lilke point 1   point 2   or any easy name to remember       once your places are added and flagged go back to the main Window in your google app      click on the blue circle with the arrow in your bottom right      a new windwo will open and you can see on the top there are two text fields in which you can add your  from location  and  distance location        click on any text field and type in your saved location in point 3       click on the other text field and add your next saved location        By doing so  google maps will calculate the distance between the two locations and show you the blue path on map       Good luck

salman khan what Usman Kurd suggested is perfect  Only thing i found which can be corrected is that  For google maps v2 we use LatLng class  So below is the code of Usman Kurd that can be used for Google Maps v2  I checked it works perfect   public double CalculationByDistance LatLng StartP  LatLng EndP            int Radius 6371   radius of earth in Km                  double lat1   StartP latitude          double lat2   EndP latitude          double lon1   StartP longitude          double lon2   EndP longitude          double dLat   Math toRadians lat2-lat1           double dLon   Math toRadians lon2-lon1           double a   Math sin dLat 2    Math sin dLat 2            Math cos Math toRadians lat1     Math cos Math toRadians lat2             Math sin dLon 2    Math sin dLon 2           double c   2   Math asin Math sqrt a            double valueResult  Radius c          double km valueResult 1          DecimalFormat newFormat   new DecimalFormat                  int kmInDec    Integer valueOf newFormat format km            double meter valueResult 1000          int  meterInDec  Integer valueOf newFormat format meter            Log i  Radius Value     valueResult     KM    kmInDec   Meter     meterInDec            return Radius   c

All this answers will give you the distance in a straight line  If you need to get the distance by road  you have to parse the JSON that Google sends you back after calling his service  You can use this method   public String getDistance final double lat1  final double lon1  final double lat2  final double lon2       String parsedDistance      String response          Thread thread new Thread new Runnable                  Override             public void run                     try                        URL url   new URL  http   maps googleapis com maps api directions json origin     lat1         lon1     amp destination     lat2         lon2     amp sensor false amp units metric amp mode driving                        final HttpURLConnection conn    HttpURLConnection  url openConnection                        conn setRequestMethod  POST                        InputStream in   new BufferedInputStream conn getInputStream                         response   org apache commons io IOUtils toString in   UTF-8                         JSONObject jsonObject   new JSONObject response                       JSONArray array   jsonObject getJSONArray  routes                        JSONObject routes   array getJSONObject 0                       JSONArray legs   routes getJSONArray  legs                        JSONObject steps   legs getJSONObject 0                       JSONObject distance   steps getJSONObject  distance                        parsedDistance distance getString  text                       catch  ProtocolException e                        e printStackTrace                      catch  MalformedURLException e                        e printStackTrace                      catch  IOException e                        e printStackTrace                      catch  JSONException e                        e printStackTrace                                                    thread start        try           thread join          catch  InterruptedException e            e printStackTrace              return parsedDistance      lat1 and lon1 are coordinates of origin  lat2 and lon2 are coordinates of destination

In Google Map API V2 You have LatLng objects so you can t use distanceTo  yet    You can then use the following code considering oldPosition and newPosition are LatLng objects       The computed distance is stored in results 0     If results has length 2 or greater  the initial bearing is stored in results 1     If results has length 3 or greater  the final bearing is stored in results 2   float   results   new float 1   Location distanceBetween oldPosition latitude  oldPosition longitude                  newPosition latitude  newPosition longitude  results     For more informations about the Location class see this link
