download osmdroid-android-3.0.0.jar, include it in your project, and use in your layout like:

Syntax: [ Download ] [ Hide ]
Using xml Syntax Highlighting
  1.   <org.andnav.osm.views.OpenStreetMapView
  2.    xmlns:android="http://schemas.android.com/apk/res/android"
  3.    android:id="@+id/mapview"
  4.    android:layout_width="fill_parent"
  5.    android:layout_height="fill_parent"
  6. />
  7.

the layout isnt the problem.
is the java part the same as with the normal MapView (just add OpenStreetMapView)?

Yes, most main methods are same. In my opinion OpenStreetMapView is better, you can use offline maps, many other map sources (mapnik, osm, cycle maps etc..).
I used it this way:
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. this.mapView = (OpenStreetMapView) this.findViewById(R.id.mapview);        
  2. this.mapController = this.mapView.getController();
  3. this.mapController.setZoom(mapUtils.zoomlevel);
  4. this.mapView.setBuiltInZoomControls(true);
  5. this.mapView.setMultiTouchControls(true);
  6. this.mLocationOverlay = new MyLocationOverlay(this.getBaseContext(), this.mapView);
  7. this.mapView.getOverlays().add(this.mLocationOverlay);
  8.

Re: OpenStreetMap MapView for Android

Hi,

just found this (quite old) forum thread while searching for an alternative to GoogleMap MapView which supports offline rendering. The osmdroid project really seems promising. In this context I also stumbled upon a project called mapsforge (http://mapsforge.org). The screenshots (http://code.google.com/p/mapsforge/) of their maps look really great. They claim that they have offline maps (rendering on device) and that their MapView is compliant with the GoogleMaps API (just substitute the imports...). Has anyone tried their API? Can anyone suggest me which library to use (osmdroid, mapsforge, or other I'm not aware of)?

Best regards

I slightly rewrite my code to use osmdroid mapview, not old openstreetmapview, because some overlays like mylocationoverlay not worked. Now is all ok. Codes and download link are updated.

thanks a lot i finally got the trick and it works now!

but i have one question:
in your example code you use another lib (slf4j-android-1.5.8.jar) instead of the latest osmdroid-android-3.0.0.jar.

is that lib free to use (GNU licence?) as well? and where does it come from?
when i do NOT use that lib (slf4j-android-1.5.8.jar) and keep using the osmdroid libs only, i get this error:

so i wonder whats wrong (it works when i use your lib...).

It seems thats a logging framework. See http://www.slf4j.org/android/
I probably grab it from their openstreetmapviewer in svn.
