Implementation of Google Maps v2 steps
1. Download and install Google Play Services.
2. Import Google Play Services Library in Eclipse by selecting from
android-sdk-windows\extras\google\google_play_services\libproject\google-play-services_lib
3. Generate SHA-1 fingerprint using java Keytool (Refer : Generate MD5 ).
4. Create Google project in Google API console
5. Turn on Google Maps Android API v2 from Services.
6. Create new Android Key by entering SHA 1 key and package name separated by semicolon(;).
7. Create new project and select google play services library that already imported.
8. Modify & Add Permissions in AndroidManifest.xml
7. Create new project and select google play services library that already imported.
8. Modify & Add Permissions in AndroidManifest.xml
Add Map key:
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AdW3rfecsfDerf3a-M5JO9p6wksdfweEW3o" />
Add Permissions:
<xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="your_package_name"
android:versionCode="1"
android:versionName="1.0" >

android:value="AdW3rfecsfDerf3a-M5JO9p6wksdfweEW3o" />
</application>
</manifest>
9. Create MapsFragement for google map on activity by add fragment in activity.xml
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
10. Add the following code in your MainmapActivity.java
public class MainmapActivity extends Activity {
// Google Map
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* function to load map. If map is not created it will create it for you
* */
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
@Override
protected void onResume() {
super.onResume();
initilizeMap();
}
}
11. Run your project and congratulations if you see a map displaying on your device.
