How to implement Google Maps new version of API v2

Question

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"?>  
                <fragment xmlns:android="http://schemas.android.com/apk/res/android"  
                          android:id="@+id/map"  
                              android:layout_width="match_parent"  
                                  android:layout_height="match_parent"  
                               class="com.google.android.gms.maps.MapFragment"/>  

and finally my manifest file

                           <?xml version="1.0" encoding="utf-8"?>  
                 <manifest xmlns:android="http://schemas.android.com/apk/res/android"

                          </manifest>  

i run my application in emulator of version 4.2 and api level of 17 i got following error

[Adrián Rodríguez]

the map access permissions must begin with the name of your package. Replace <permission android:name="com.codebybrian.mapsample.permission.MAPS_RECE‌​IVE" android:protectionLevel="signature"/> with <permission android:name="com.example.apv.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>

i have done that thing but when i start running it the above are my errors

[Cameron Lowell Palmer]

Incorrect. The Google docs for Maps explicitly state otherwise.
