Hi every one I came to know that google maps has deprecated its previous version API v1 and introduced a new version of google maps API v2. I tried out one example by following some links in google any how i am pretty sure that i got the api key correctly by providing the exact hash key code and managed to get the correct api key. Now i managed to write some code as well but when i tried to execute the code i am getting the errors please help me to solve this here is my code
and i even tried the sample codes provided by google play services an i got the same problem
this is the sample that i have done by referring some links in google
main activity class
package com.example.apv;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import android.os.Bundle;
import android.app.Activity;
import android.app.FragmentManager;
public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FragmentManager fragmentManager = getFragmentManager();
MapFragment mapFragment = (MapFragment)fragmentManager.findFragmentById(R.id.map);
GoogleMap googleMap = mapFragment.getMap();
LatLng sfLatLng = new LatLng(37.7750, -122.4183);
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.addMarker(new MarkerOptions().position(sfLatLng).title("San Francisco")
.snippet("Population: 776733")
.icon(BitmapDescriptorFactory.defaultMarker(
BitmapDescriptorFactory.HUE_AZURE)));
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(true);
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(sfLatLng, 10))
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?>

and finally my manifest file
