Google Maps Android API v2: how can i set marker over "blue dot" (z order)

I am writing an app using Google Maps Android v2 SDK. When I place a marker on the map at my location, it always appears underneath the default "blue dot" from the built-in my location layer. This does not happen when using the Google Maps SDK for iOS. How can I make my own marker be drawn on top of the blue dot?

You can add marker on your location like this :
LatLng latLng = new LatLng(mCurrentLocation.getLatitude(),
mCurrentLocation.getLongitude());
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title("You");
mCurrLocationMarker = mGoogleMap.addMarker(markerOptions);
mCurrLocationMarker.setVisible(true);
Please search google or stackoverflow first always..Hope it helps

markers have a zIndex() value which you can use

Move the marker along the with map as the user moves

I have implemented google map into my app. I have added a custom marker at my current location.I want to move the marker as the user moves, along with the map. I want to implement the functionality as in google maps navigation. While googling i found the following links but did not get the result. so can any one help me out ?
I have added this in onLocationChanged()
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
sourceLocation = latLng;
startPoint = new GeoPoint(latLng.latitude,latLng.longitude);
forNavigation = location;
// animation
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
// Zoom in the Google Map
mMap.animateCamera(CameraUpdateFactory.zoomTo(15));
// mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(mPositionMarker.getPosition(), 15));
mMap.animateCamera(CameraUpdateFactory.newLatLng(new LatLng(location
.getLatitude(), location.getLongitude())));
These are the links which i found

Plotting on maps in android

I am making an application where I get an message with latitude and longitude, I search that and then plot it on google maps.
How to accomplish the plotting ??

If by "plotting on the map" you mean adding a marker (icon) to a map at a given Latitude / Longitude, you can use the following code to put a Marker on Sydney on the map :
private GoogleMap mMap;
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
mMap.addMarker(new MarkerOptions()
.position(new LatLng(-33.88,151.21))
.title("Hello world"));
The LatLng object accepts 2 doubles representing a latitude and a longitude in degrees.
The Google Maps Android API v2 is pretty well-documented. There's also a guide on Markers in Google Maps Android API v2
