Mapactivity Class In Android?

when i extends the MapActivity class it shows an error. error is: cant resolved datatype. why? how to add a maps.jar in my project? thanks.

Solution 1:

You probably haven't done the steps required to set up a Maps project as described in Maps External API Overview. There is no maps.jar to add. Read the document I linked to, and you should be all set.

Solution 2:

Google Map View : Creating a Map Activity

Solution 3:

Here is my code :

import java.io.IOException;
    import java.util.List;
    import java.util.Locale;

    import android.content.Context;
    import android.graphics.Canvas;
    import android.location.Address;
    import android.location.Geocoder;
    import android.location.Location;
    import android.location.LocationListener;
    import android.location.LocationManager;
    import android.os.Bundle;
    import android.widget.Toast;

    import com.google.android.maps.GeoPoint;
    import com.google.android.maps.MapActivity;
    import com.google.android.maps.MapController;
    import com.google.android.maps.MapView;
    import com.google.android.maps.Overlay;

    publicclassMyMapsActivityextendsMapActivity 
    {    

            MapView mapView;
        MapController mapController;
        LocationManager locationManager;
        LocationListener locationListener;
            /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState)
                 {
                   super.onCreate(savedInstanceState);
                   setContentView(R.layout.main);

                    mapView = (MapView) findViewById(R.id.mapView);
                    // enable Street view by default
                    mapView.setStreetView(true);

                    // enable to show Satellite view// mapView.setSatellite(true);// enable to show Traffic on map// mapView.setTraffic(true);

                    mapView.setBuiltInZoomControls(true);

                    mapController = mapView.getController();
                    mapController.setZoom(5); 


       locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);  

       locationListener = newGPSLocationListener();

       locationManager.requestLocationUpdates(
      LocationManager.GPS_PROVIDER,

      0,

    overlayList.add(t);

      Toasttoast= Toast.makeText(contexto, msg, Toast.LENGTH_SHORT);

  }
