Answer 1

Follow this code.Hope this might help.Make the changes where ever necessary according to your requirement.I think you are adding this map view as a fragment in a tab view.

    public class DealsCloseBy extends Fragment {

    SupportMapFragment mMapView;
    private GoogleMap googleMap;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // inflat and return the layout
        View v = inflater.inflate(R.layout.fragment_deals_close_by, container, false);
        mMapView = ((SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map));
        mMapView.onCreate(savedInstanceState);

        mMapView.onResume();// needed to get the map to display immediately

        try {
            MapsInitializer.initialize(getActivity().getApplicationContext());
        } catch (Exception e) {
            e.printStackTrace();
        }

        googleMap = mMapView.getMap();
        // latitude and longitude
        double latitude = 13.0294278;
        double longitude =80.24667829999999;

        // create marker
        MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps").icon(BitmapDescriptorFactory.fromResource(R.mipmap.map_pin));

        // Changing marker icon
        // marker.icon(BitmapDescriptorFactory
        // .defaultMarker(BitmapDescriptorFactory.HUE_ROSE));

        // adding marker
        googleMap.addMarker(marker);
        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(new LatLng(13.0294278, 80.24667829999999)).zoom(12).build();
        googleMap.animateCamera(CameraUpdateFactory
                .newCameraPosition(cameraPosition));

        // Perform any camera updates here
        return v;
    }
}

In xml file,in place of map fragment,use:-

    <fragment
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    class="com.google.android.gms.maps.SupportMapFragment"/>

If you use the latest GooglePlayServices you can use the getMapAsync function which will automatically initializes the maps system and the view.

Also use a MapView in the layout

This is how I added the map in fragment.

public class MapFragment extends Fragment implements OnMapReadyCallback {

     @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
            view = inflater.inflate(R.layout.fragment_tab_fragment1, container, false);

            FragmentManager manager = getFragmentManager();
            FragmentTransaction transaction = manager.beginTransaction();
            SupportMapFragment fragment = new SupportMapFragment();
            transaction.add(R.id.mapView, fragment);
            transaction.commit();

            fragment.getMapAsync(this);

            return view;
        }

   @Override
   public void onMapReady(GoogleMap map) {
      //map is ready
      map.addMarker(...
 }
}

in xml

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

To use the latest GooglePlayService put this in gradle

compile 'com.google.android.gms:play-services:8.3.0'
