 map.clear();

 MarkerOptions mp = new MarkerOptions();

 mp.position(new LatLng(location.getLatitude(), location.getLongitude()));

 mp.title("my position");

 map.animateCamera(CameraUpdateFactory.newLatLngZoom(

for getting current position you can use getLastKnownLocation() method on LocationManager:

LatLng current = new LatLng(currentLocation.getLatitude(), currentLocation.getLongitude());

I am developing an application in which I want to display current location using marker in my map. I am using Google Map v2. Here I can display Map and marker when GPS is off ,but not visible any marker on map when GPS on. My requirement is display marker on map with current position

I tried like this,

<pre><code>@Override
public void onLocationChanged(Location location) {
 // TODO Auto-generated method stub

 //locationManger.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, 
 this);

 ArrayList&lt;HashMap&lt;String, String&gt;&gt; arl = (ArrayList&lt;HashMap&lt;String, String&gt;&gt;) 
 getIntent().getSerializableExtra("arrayList");


 if(location!=null){
 double latitude = location.getLatitude();
 double langitude = location.getLongitude();


 myPosition = new LatLng(latitude, langitude);
 CameraPosition position= new CameraPosition.Builder().
 target(myPosition).zoom(17).bearing(19).tilt(30).build();
 //_googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(position));

 _googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(position)); 
 _googleMap.addMarker(new 
 MarkerOptions().position(myPosition).title("start"));
 }
