Android :: Unable To View Map On Android Emulator

I am unable to view maps on the emulator. I am under proxy internet connection, I also set the proxy via GUI and also have set api Key alongwith the permissions and library. here's my code:
package com.example.MyMapActivity;
import org.apache.http.HttpHost;
import org.apache.http.conn.params.ConnRoutePNames;
import org.apache.http.impl.client.DefaultHttpClient;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
public class MyMapActivity extends Map Activity {
private MapView mapview;
private MapController mapcontroller;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)}
