It looks to me like you have a few errors in onCreate(). You are
trying to add an OverlayItem to your ItemizedOverlay before you
instatiate the ItemizedOverlay. And you also try adding that overlay
to the list of overlays before you get the list of overlays you want
to add it to.

This is all out of order. You need to initialize your variables before
you try to use them.
Try this in your onCreate():
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.setSatellite(true);
mapOverlays = mapView.getOverlays();
drawable = this.getResources().getDrawable(R.drawable.androidmarker);
itemizedOverlay = new NewItemizedOverlay(drawable);
GeoPoint point = new GeoPoint(19240000,-99120000);
OverlayItem overlayitem = new OverlayItem(point, "", "");
itemizedOverlay.addOverlay(overlayitem);
Hope that helps!
