main activity

public class MainActivity extends FragmentActivity { GoogleMap map; @SuppressLint("NewApi") @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); map=((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

map.setMapType(GoogleMap.MAP_TYPE_NORMAL);

Answer 1

Import google play services, check this link to know how to import it.

And change the line map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)) .getMap(); to map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) .getMap();

Answer 2

If you are extending from FragmentActivity means you are developing the app for target below 11. You should use the SupportMapFragment.

SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

See my blog posts i have tried to summarize all there is needed to build an App with Google Maps API V2 for Android.

1. Solution to Problems with Maps API V2(using google_play_services_lib).
2. Creating an Android App with Maps API V2 for minSDK=8 (Android 2.2 Froyo).
3. Creating an Android App with Maps API V2 for minSDK=11 (Android 3.0 HoneyComb).
