Driving distance and travel time duration between two locations in Google Map Android API V2

March 25, 2013

In this article, we will develop an Android application which displays driving distance and travel time between two locations in Google Map Android API V2. It also draws polyline along driving route from start location to end location.

Screenshot of this application is shown in the Figure 7 below.

This application makes use of Google Map Android API V2 and Google Directions API.

This application is developed in Eclipse (4.2.1) with ADT plugin (21.1.0) and Android SDK (21.1.0) and tested in a real Android device (Android 2.3.6  -  GingerBread).

1. Create a new Android application project namely “LocationDistanceTimeMapV2″

6. Download and configure Google Play Services Library in Eclipse

Google Map for Android is now integrated with Google Play Services. So we need to set up Google Play Service Library for developing Google Map application in Android.

Please follow the given below link to setup Google Play Service library in Eclipse.


7. Add Google Play Services Library to this project

Linking Google Play Services Library to this project

8. Get the API key for Google Maps Android API V2

We need to get an API key from Google to use Google Maps in Android application.

Please follow the given below link to get the API key for Google Maps Android API v2.


9. Add Android Support library to this project

By default, Android support library (android-support-v4.jar ) is added to this project by Eclipse IDE to the directory libs. If it is not added, we can do it manually by doing the following steps :

  • Open Project Explorer by Clicking “Window -> Show View -> Project Explorer”
  • Right click this project
  • Then from popup menu, Click “Android Tools -> Add Support Library “

10. Update the file res/values/strings.xml

<?xml version="1.0" encoding="utf-8"?>
    <string name="app_name">LocationDistanceTimeMapV2</string>
    <string name="action_settings">Settings</string>
    <string name="hello_world">Tap two locations in the map</string>
    <string name="str_tv_distance_time">Distance</string>

11. Update the layout file res/layout/activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    tools:context=".MainActivity" >

        android:layout_alignParentTop="true" />

        android:layout_below="@id/tv_distance_time" />


12. Create a new class namely “DirectionsJSONParser” in the file src/in/wptrafficanalyzer/locationdistancetimemapv2/DirectionsJSONParser.java

package in.wptrafficanalyzer.locationdistancetimemapv2;

    in source it will not showing any error.but when i running it shows “ur project contain error”can u please send exact project with apk to my email.
    thank u.

    • aroma on April 29, 2015 at 9:23 pm

      hi, i am also using this code. I found out one line is missing which is
      (TextView)tv_distance_time=(TextView) getActivity().findViewById(R.id.tv_distance_time);
      I am not sure whether this is your problem.

      • nick75 on April 29, 2015 at 9:25 pm

        that line does not missing dude =)

    • amar on July 25, 2015 at 8:17 am

      In code no errors, but when executing, unfortunately app closing, can u send complete code my email sir, using android studio sir…

  2. imam nur on March 26, 2013 at 7:19 pm

    Wow you’re awesome sir.. big thanks for you.. :)

    I want to ask you again if you wish. in my final project in college, I wanted to create a custom marker with an image that I put in drawable (Local Storage). if the maps V1, I still know how. but if I want to make in V2 maps, why not work?

    sorry if I am asking a lot, but I really appreciate you for your help so far. :)

  3. cyberhagz on March 26, 2013 at 7:31 pm

    how do if I want a custom marker on maps v2?

  4. Basribaz on March 26, 2013 at 8:46 pm

    very good article….
    but how to make a list of places with latitude and longitude when

    Google map in android application step by step list of directions such as left and right how can I do traffic direction signs. You can do it this way or example.

  6. mohit on March 29, 2013 at 10:52 am

    sir can you plz upload a app with source code having location tracking of another android device from my android device

  7. imran khan on April 4, 2013 at 3:01 pm

    it`s required googleplay service apk in emulator & device.facing issues in testing will you provide me your solution to run this program over emulator

    • george on April 4, 2013 at 3:20 pm

      Since, Google Play Store is not available in emulator, we can not run Google Map Android API V2 applications in emulator. I tested this application in a real Android device.

      • imran on April 8, 2013 at 4:59 pm

        Thanks, now working fine on device, i am also looking for Android Proximity Alerts in MAP v2. any help.

  8. Nuno Freitas on April 26, 2013 at 6:57 pm

    if the route have more waypoint, what needs to change in the code to get the distance and time for that route.

    Thanks for the tutorials, very helpfull.

  9. steve on April 27, 2013 at 2:41 am

    Quick question…how can i get access to the points from the jason file in their arraylist?

    It drawsa the points on…but i cant do anything with it now :(

  10. steve on April 27, 2013 at 2:44 am

    I worded that badly…it draws the maps…but I want an arraylist of latlng points back in my mainactivity file. Cant for the life of me figure it out.

    Was just trying to use the points array from the bottom but its always null if i try and call it to the top.

    • george on April 27, 2013 at 4:31 am

      Assign the argument variable “result” of the method “onPostExecute()” to a member variable so that we can reuse it in the class “MainActivity”.

  11. ks on May 7, 2013 at 7:39 pm

    Hi George,

    First, thanks for your great tutorial!
    This project is aim to Showing Driving distance and time between two locations.

    Wonder can how can I get the time on ‘walk’ instead of ‘Driving’?


    • george on May 7, 2013 at 7:56 pm


      Add the parameter “mode=walking” into Google directions url built in the method getDirectionsUrl() of the class MainActivity.

      • ks on May 7, 2013 at 8:09 pm

        pardon me. Is the url like this?

        String url = “https://maps.googleapis.com/maps/api/directions/”+output+”?”+parameters+”mode=walking”;

        after added the mode, the app always show ” No Point”

        • ks on May 7, 2013 at 8:15 pm

          Fixed, a silly mistake made

          • gonzalo on September 17, 2013 at 4:16 am

            How can you fixed?

  12. ks on May 7, 2013 at 8:04 pm


    I am trying to add the duration information in your another app:
    “Route directions for driving mode, bicycling and walking mode in Google Map Android API V2″

    and got many tips from your blog

  13. ages on May 9, 2013 at 2:29 am

    Hi George,

    First, thanks for your great tutorial!

    Wonder can how to make driving distance, travel time and draws polyline along driving route from my location to custom place which we mark in program??

  14. imam on May 9, 2013 at 1:25 pm

    Hello Sir, I would like to ask.
    In my final project in college, I wanted to make application directions by car object using Goggle Maps, I’ve tried the tutorial Driving distance and travel time duration between two locations in Android Google Map API V2, but here I was asked to prove the route pointer journey from google maps and Google Map route pointing journey using Hill Climbing. Roughly how to implement it.
    please your help and thank you before sir
    warm regrads,

      Hello Jacks,

      I think there is some error in your layout file. Please ensure that, the package name for SupportMapFragment class is specified correctly.

      Also please check your class com.petadirection.MainActivity is extending the class FragmentActivity

    Hi George,

    With no doubts your tutorials are the best I managed to find on the web. As many others said thank you very much for this.

    Small question however, how can I implement a logic which will display nearby points of interest (which I would store locally within my app, ie: an XML) along the driving route?

    Can you please suggest?

    Thanks and regards

    How to add information cost of distance calculation with custom value ?

    Thank you so much!

      String distance;
      distance = (String) point.get(“distance”);
      tv_distance.setText(“Distance:” + distance + “, Duration:” + duration);

      distance = distance.replaceAll(“[A-Za-z]“, “”);
      tv_distance.setText(“Distance:” + distance + “, Duration:” + duration);

      Remove Alphabets from receiving Distance @rahul
