Use MapView in your xml

and Use the below code for the GoogleActivity:

public class GoogleActivity extends Activity {
    private GoogleMap mGglMpInstance;
    private MapView mMapView;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            try {
                MapsInitializer.initialize(MainActivity.this);
            } catch (GooglePlayServicesNotAvailableException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } 
            initailizeLayout(savedInstanceState);
        }

        private void initailizeLayout(Bundle savedInstanceState){
            mMapView=(MapView)findViewById(R.id.mMapView);
            mMapView.onCreate(savedInstanceState);
            mGglMpInstance=mMapView.getMap();
    }
