Android Geocoding – Showing User Input Location on Google Map Android API V2

In this article, we will create an Android application which facilitates users to input street address in an EditText and on clicking the find button, application draws corresponding location marker on the Google Map Android API v2 using Google’s Geocoder API.

This application is an upgraded version of the application discussed in the article titled “Android Geocoding – Showing User Input Location on Google Map” where the location is shown in Google Map Android API v1.

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

1. Download and configure Google Play Services Library in Eclipse

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 “LocationGeocodingV2″

Figure 1 : Create new Android application project

3. Configure Android Application Project

Figure 2 : Configure Android Application Project

4. Design Application Launcher Icon

Figure 3 : Design 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 to Google Play Services Library

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 AndroidManfiest.xml

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

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

13. Update the file src/in/wptrafficanalyzer/locationgeocodingv2/MainActivity.java

14. Screenshot of the application in execution

Figure 7 : Showing Street Address in Google Map Android API V2

15. Download Source Code
