This is click event from where i call map.

mListView.setOnItemClickListener(new OnItemClickListener()
        {
            public void onItemClick(AdapterView<?> parent, View v,
                    int position, long id)
            {
                ParsedData o = Retailerdata.get(position);

                Intent intenRetailerLocation = new Intent(
                        RetailerListing.this, RetailerLocation.class);
                intenRetailerLocation.putExtra("Lat", Float.valueOf(o
                        .getLat()));
                intenRetailerLocation.putExtra("long", Float.valueOf(o
                        .getLong()));
                intenRetailerLocation.putExtra("Adress", o.getAddress());
                intenRetailerLocation.putExtra("zip", o.getZip());
                intenRetailerLocation.putExtra("city", o.getCity());
                intenRetailerLocation.putExtra("Description", o
                        .getDescription());
                startActivity(intenRetailerLocation);
                finish();

            }

        });

Class in which use the google map

@Override
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState);// Error comes on this line      
        setContentView(R.layout.retailerlocation);

        myLayout=(RelativeLayout)findViewById(R.id.MyLayout);
        mImageView = (ImageView) findViewById(R.id.picture);
        mContainer = (ViewGroup) findViewById(R.id.container);

    topTitle=(TextView)findViewById(R.id.SelectedGameName);
    mMapView = (MapView) findViewById(R.id.mMapView);
    mMapView.setTraffic(false);
    mMapView.setStreetView(false); 
    mMapView.setSatellite(false);

    mMapView.setBuiltInZoomControls(true);

Make sure that the Activity in which you use the Google Maps extends the com.google.android.maps.MapActivity.
