I have followed about two tutorials from vogella and some other tutorial that looked similar...very similar but to no avail. I load the app on my nexus 7 and it just crashes "Unfortunately MyMapView has stopped working" on launch.This is the manifest:
`

<uses-sdk
    android:minSdkVersion="17"
    android:targetSdkVersion="17" />
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>


<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <uses-library android:name="com.google.android.maps" />

    <activity
        android:name="com.macmozart.mymapview.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyBZ1Bt7rjB863Jy-B05zls6k8XZsBGQ6-4" />
</application>

`
Followed by my main layout:

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

and finally my java class:

package com.macmozart.mymapview;

import android.app.Activity;
import android.os.Bundle;

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.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
import com.google.android.maps.*;

public class MainActivity extends Activity {

    static final LatLng HAMBURG = new LatLng(53.558, 9.927);
    static final LatLng KIEL = new LatLng(53.551, 9.993);
    private GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
                .getMap();

        if (map != null) {
            Marker hamburg = map.addMarker(new MarkerOptions()
                    .position(HAMBURG).title("Hamburg"));
            Marker kiel = map.addMarker(new MarkerOptions()
                    .position(KIEL)
                    .title("Kiel")
                    .snippet("Kiel is cool")
                    .icon(BitmapDescriptorFactory
                            .fromResource(R.drawable.ic_launcher)));

            map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

            // Zoom in, animating the camera.
            map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);

        }

    }
}

Any idea what im doing wrong I really need this to work
