Adding Compass to Rotate MapView

Question

I'm using the code of MapsDemo Sample to draw a Map that rotates according to the compass, but enableCompass is not working to show the compass on MapView. I tried to add this compass http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/Compass.html. But when I add it to my application, the arrow appears frozen. Any ideas?

Bear in mind that it will only work on actual hardware.

Put this line in onCreate:

    MyLocationOverlay me = new MyLocationOverlay(this, mapView);
    mapView.getOverlays().add(me);

Then add this:

@Override
protected void onResume() {
    super.onResume();
    me.enableCompass();
}

@Override
public void onPause() {
    super.onPause();
    me.disableCompass();
}

Here is a sample project that enables the compass on MyLocationOverlay that definitely works, though you will need to substitute in your own android:apiKey value.
