Showing current location in Google Maps using API V2 with SupportMapFragment

January 6, 2013

In this article, we will create an Android application which will display current location in Google Maps using Google Maps Android API V2.

Since the Google Map is displayed using SupportMapFragment, this application can run in Android API Level 8 or above.

In order to use MapFragment for Google Maps, we need Android device with API level 12 or above.

This application is developed in Eclipse 4.2.1 with ADT plugin ( 21.0.0 ) and Android SDK ( 21.0.0 ). This application is tested in a real Android Phone with Android ( 2.3.6 ).

An alternative method for this application is available at Showing current location using OnMyLocationChangeListener in Google Map Android API V2

1. 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.

http://developer.android.com/google/play-services/setup.html

2. Create a new Android Application Project namely “LocationInGoogleMapV2″

Figure 1 : Create a new Android Application Project

3. Configure Android Application Project

Figure 2 : Configure Project

4. Design Application Launcher Icon

Figure 3 : Designing Application Launcher Icon

5. Create a blank activity

Figure 4 : Create a blank activity

6. Enter Main Activity Details

Figure 5 : Enter Main Activity Details

7. Link to Google Play Service Library

Figure 6 : Link 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.

https://developers.google.com/maps/documentation/android/start

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 window, Click “Android Tools -> Add Support Library “

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


<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">CurrentLocation</string>
    <string name="hello_world">Hello world!</string>
    <string name="menu_settings">Settings</string>
</resources>

11. Update the file AndroidManfiest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="in.wptrafficanalyzer.locationingooglemapv2"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

    <permission
        android:name="in.wptrafficanalyzer.locationingooglemapv2.permission.MAPS_RECEIVE"
        android:protectionLevel="signature"/>

    <uses-permission android:name="in.wptrafficanalyzer.locationingooglemapv2.permission.MAPS_RECEIVE"/>

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <activity
            android:name="in.wptrafficanalyzer.locationingooglemapv2.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
             android:value="YOUR_API_KEY"/>

    </application>
</manifest>

Note : In the above code, replace “YOUR_API_KEY” with the api key, you generated in step 8.

12. Update the layout file to display Google Map using SupportMapFragment


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

    <TextView
        android:id="@+id/tv_location"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/tv_location"
        class="com.google.android.gms.maps.SupportMapFragment" />

</RelativeLayout>

13. Update the file src/in/wptrafficanalyzer/locationingooglemapv2/MainActivity.java


package in.wptrafficanalyzer.locationingooglemapv2;

        // Zoom in the Google Map
        googleMap.animateCamera(CameraUpdateFactory.zoomTo(15));

        // Setting latitude and longitude in the TextView tv_location

  Have you figured out how to provide option to activate GPS from application and then returning back to the application with the current location on maps.
Ranjith Kumar on January 24, 2013 at 5:24 pm
For me only white screen shown no map
- george on January 24, 2013 at 9:21 pm

Dear George,
Nice tutorial.

Do u have any idea what is causing this problem?
I have tried many other solutions/examples and nvr get the map to show on my device. (I have a 2.2 Froyo device)

…
- george on February 3, 2013 at 6:40 am
  Dear Michael,
  Please ensure that, the correct API key is entered in the AndroidManifest.xml.
  Google Maps Android API V2 applications will not be executed in emulators since it require Google Play Services library.
  - alaintchato on March 21, 2013 at 4:15 pm
    I too i’m getting on the white screen with lat and long.
    I assure you that my API KEY and package name are correct
    What could be the problem
    - alaintchato on March 21, 2013 at 4:21 pm
      Also, my logcat doesn’t show anything significant..only some ‘pause 4ms+…’ stuff
mellon on February 7, 2013 at 8:44 am
thanks, it’s very helpful. Finally found the solution to show current location!!!!
ign on March 7, 2013 at 12:24 am
Thanks man, worked like a charm!
As for those who have white screen problems – make sure that you got the right API key and package name is yours one (if you’ve changed it while following the tutorial) in AndroidManifest.xml

Hi, George! Thanks for this great tutorial, really helped me.
I’ve got problem with GooglePlayServicesUtil. Its says “cannot be resolved”. How to fix it??
sorry for my bad english :p
- george on April 25, 2013 at 10:50 am
  Ensure that, you downloaded and configured Google Play Services library as mentioned in the Step 1.
  Once Google Play Services library is configured, then link that library to this project as shown in the Step 7.
  - newbie on April 25, 2013 at 11:24 am

Priyank Pandya on April 26, 2013 at 6:43 pm
i got the lantitute and latitude bt not getting map in place of that getting white screen
- george on April 26, 2013 at 8:20 pm
  In this application the latitude and longitude are obtained using LocationManager api.
  If you are getting a white screen instead of map, probably you may not have entered the correct Android API Key in AndroidManifest.xml file.
  - Priyank Pandya on April 29, 2013 at 9:46 am
    I put the appropriate Api key also bt i think is there any other apk we need to install before run this application…??
    - george on April 29, 2013 at 11:02 am
      Please check the logcat to get a hint on the white screen
      - Priyank Pandya on April 29, 2013 at 2:03 pm
        logcat is not showing any error..

        Thanx in Advance
      - george on May 6, 2013 at 10:15 am
        Hi Priyank Pandya,
        Please ensure that, Google Maps Android API v2 service is enabled in Google APIs Console.
hosni on April 29, 2013 at 12:33 am
this app won’t run unless you update google play services
Rasmus Friis on May 5, 2013 at 9:33 pm
Hi George,
We are making a running app for school, and i have tried several different ways of showing the current users MyLocation, your solution works great.
But when you are moving, the camera does not update your current new location, so it is in the middle of the screen the whole time. Why is that, i cant find a solution for google Maps v2 which will move to the rigt location automatic. Hope you can help me.
- george on May 6, 2013 at 9:50 am
  Hello Rasmus,
  This application will automatically update the current location, even when the device is moving.

  Hi,
  Please do the following :
  * Open properties window by right clicking the project from eclipse’s package explorer
  * Select Java Build Path -> Order and Export tab
  * Ensure “Android Private Libraries” is checked
  * If unchecked, “check” it and click ok
  * Clean and Build the project and run the application

Hi sir,your tutorials r very helpful.Is it possible that one user update the map (make a marker on map saying traffic jam on some road ) can be seen to other users using that app too.
plz help
- George Mathew on August 15, 2013 at 10:32 pm
  sure you can.
  ( Cloud + Google cloud message ) is a solution for your problem
  Cloud : for updating data in the server
  Google cloud messaging : for informing clients regarding updated data
  - osig on August 16, 2013 at 8:35 pm

    - Himanshu on August 16, 2013 at 8:47 pm

Dimitrios Michalakis on January 12, 2014 at 5:51 pm
Hi George, great job sincerely.
Your app works great but when I move my device i notice that the textview with the current location coordinates does not changes, although my position on the map changes correctly.
Any solution
PD on January 29, 2014 at 3:20 pm
Hi George,
Great work here!!
I have a doubt .. is it possible to show just the available possible routes to the user? i.e. from Location A to B which possible routes are there. And then when user selects one of the route .. you show the selected route on the Map?
Does Map API or Direction API allows this?
- Pearl Malik on April 23, 2014 at 9:21 pm
  Use Directions API. He has an example for that too. Keep the polyline somewhat thick for neatness,
robin on February 13, 2014 at 5:56 pm
How do i add a marker to current location and keep updating that marker in onlocationchanged to the new location point.
- Pearl Malik on April 23, 2014 at 9:23 pm
  I think we can add Map as class variable. You can remove marker from map and add a new one again on onlocationchanged() ?
ilias on February 21, 2014 at 7:33 am

When i exported and installed it on my device it says “Unfortunately application has stopped”. Is there anything that i am missing.

Hey nice code man!! I have a doubt.

Kevin on July 10, 2015 at 1:20 pm
Hi George,
Thank you so much for this tutorial – it works fantastic.
Do you have any tutorial or code that will allow a user to click on more points in the map so that they can create a route with waypoints? If not, then what do you think the best way to do this would be?
Thanks in advance
