get current location

Question

I'm done creating an android program that adds a marker to a location. But I need to show CURRENT MY LOCATION in the MAP. I know this is done thru location based services but I don't know how to incorporate it into my program

Here is my onCreate command


  public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

    //map
    mapView = (MapView) findViewById(R.id.mapView);

    //zoom
    LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);  
    View zoomView = mapView.getZoomControls(); 

    zoomLayout.addView(zoomView, 
        new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, 
            LayoutParams.WRAP_CONTENT)); 
    mapView.displayZoomControls(true);

    //Philippines coordinate
    mc = mapView.getController();
    String coordinates[] = {"10.952566007", "121.78921587"};
    double lat = Double.parseDouble(coordinates[0]);
    double lng = Double.parseDouble(coordinates[1]);

    p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));

    mc.animateTo(p);
    mc.setZoom(6); 

    mapOverlay = new MapOverlay();
    listOfOverlays = mapView.getOverlays();
    listOfOverlays.clear();
    listOfOverlays.add(mapOverlay);  

    mapView.invalidate();
}

I have an onTouchEvent that places the marker. So no problem there, the problem is I need to display my location at the start of the program. It should show a mark that says, "You are here" or something like that in the map.

p.s: I think I need to change the hardcoded point to my current location point, but i don't know how to do that :|

In order to get the current location of your phone I use

LocationManager locationManager = (LocationManager)this.getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_COARSE); String bestProvider= locationManager.getBestProvider(criteria, true); Location loc = locationManager.getLastKnownLocation(bestProvider);

define uses-permissions in the AndroidManifest.xml for these (use the fine location for other stuff)

ref. http://code.google.com/p/android-bluetooth-on-motion/source/browse/trunk/BluetoothOnMotion/src/com/elsewhat/android/onmotion/BluetoothOnMotionService.java

In my application I would like to pass a paramter to the maps intent in order for maps to show a marker, but have found no way of doing it. Creating a location overlay as suggested by Rick (who is not Fred) is probably the way to go

when i incorporated this code in my program, it returns a null location. — lulala, Feb 28 '10 at 06:50
weird. Have you setup the AndroidManifest.xml in the same manner as me, ref http://code.google.com/p/android-bluetooth-on-motion/source/browse/trunk/BluetoothOnMotion/AndroidManifest.xml ? — dparnas, Mar 08 '10 at 16:37

Hello MapView shows how to place overlays. I think you want to use the MyLocationOverlay class documented in the google APIS reference to get your current location.

Another good sample that does much more than what you're looking for is the friend finder app on anddev.org: http://www.anddev.org/the_friend_finder_-_mapactivity_using_gps_-_part_i_-_ii-t93.html – RickNotFred Feb 23 '10 at 13:39
