Androidmarker not found

I'm following this tutorial to add an overlay to a google map (http://developer.android.com/guide/tutorials/views/hello-mapview.html).

mapOverlays = mapView.getOverlays开发者_StackOverflow中文版();
drawable = this.getResources().getDrawable(R.drawable.androidmarker); //there is no androidmarker.png in res folder
itemizedoverlay = new HelloItemizedOverlay(drawable);

Where can I find this icon (hdpi/ldpi and mdpi version)?

The tutorial cleary states:

First, we need the image that we'll use for our map overlay. Here, we'll use the Android on the right as our marker. Drag this image (or your own) to the res/drawable/ directory of your project workspace.

So if you are really searching for this specific androidmarker, use the one from the tutorial. You can use any other marker if you like.
