Answer 1

In android manifest file uses library goes in your aplication tags like this:

<application android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="com.google.android.maps" />
         <activity ....
         </activity>
</application>

And put ACCESS_FINE_LOCATION
ACCESS_COARSE_LOCATION permisions….
On onCreate you must define mapView like this:
MapView mapView = (MapView) findViewById(R.id.mapView); after setContent
