android-maps-v2

I am new to android, now am working with Google maps v2, I have used tabhost to show Google map v2, In this tabhost i need to show two Google maps v2 on different tab. When i switch the tab b/w two tabs which contain map, it get overlapped. I don't know to overcome this issue. //code is here for both tab mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) .getMap(); mMap.setMyLocationEnabled(true); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); //locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME,

I'm trying to create a SupportMapFragment dynamically and to put it in a FrameLayout container. My issue is that mMapFragment.getMap() returns null ... Anybody can help? CenterMapFragment.java public class CenterMapFragment extends Fragment { private SupportMapFragment mMapFragment; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.center_map_fragment, container, false); } @Override public void onActivityCreated (Bundle savedInstanceState){ super.onActivityCreated(savedInstanceState); if

How do I set the center of the map to a specific location using GMaps v2? This is how I did it using GMaps v1: public void setCenter( LatLng point ) { if( point.latitude*1000000 != 0 && point.longitude*1000000 != 0 ) { if( mMapController != null ) { mMapController.setCenter( point ); } /*else if( mOpenStreetMapViewControllerSource != null ) { mOpenStreetMapViewControllerSource.getController().setCenter( new org.osmdroid.util.GeoPoint( point.getLatitudeE6(), point.getLongitudeE6() ) ); mPostponedSetCenterPoint = point; }*/ } } I have looked through the API for GMaps v2 and can't find and

I was reading the android docs http://developer.android.com/reference/com/google/android/gms/maps/MapFragment.html and I came across this sentence: Any objects obtained from the GoogleMap is associated with the view. It's important to not hold on to objects (e.g. Marker) beyond the view's life. Otherwise it will cause a memory leak as the view cannot be released. I don't fully understand that, and I'm not sure that it applies to me, but I just wanted to check: this only applies if the fragment is destroyed while the main view still exists, right? My map fragment is the only element in that

I have an Activity with a MapFragment that I add to the Activity programmatically using a FragmentTransaction : private static final String MAP_FRAGMENT_TAG = "map"; private MapFragment mapFragment = null; ... protected void onCreate(Bundle savedInstanceState) { ... mapFragment = (MapFragment) getFragmentManager().findFragmentByTag(MAP_FRAGMENT_TAG); if (mapFragment == null) { mapFragment = MapFragment.newInstance(); FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction(); fragmentTransaction.add(R.id.fragment_wrapper, mapFragment, MAP_FRAGMENT_TAG);

When I use v6.5.87 of Google Play Services, I get a null pointer exception when I call getMapAsync() . I'm using a SupportMapFragment in my Fragment 's xml layout. My code: SupportMapFragment mapFragment = (SupportMapFragment) getActivity() .getSupportFragmentManager().findFragmentById(R.id.mapFragment); mapFragment.getMapAsync(this); Note: There's no problem when calling getMap() on older Google Play Services versions, but getMap() is now deprecated ( docs ). Here's the stack trace for the NPE: java.lang.NullPointerException at com.decos.fixi.fragments.FragmentLocationMap.initializeMap
