"Unable to resolve superclass of HelloMapView" could mean anything,
but did you make sure to subclass HelloMapView from Activity? Is
Eclipse properly set up with the SDK?
This may not be relevant, but the HelloMapView tutorial uses the
deprecated MapView.GetZoomControls() API. To fix it:
Step #7 – No longer needed
Step #8 – The “ZoomControls mZoom;” variable is no longer needed
Step #9 – Replace three lines of code with
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
Step #10 – No longer needed
