It works very well. Image resources are packaged as PNG files, lossless compression.

Some useful links:

It shouldn't be necessary to create icons from code, as there are only several fixed pre-defined resolutions, and hence, icon sizes (when expressed in pixels).

However, I find it useful to use vector-based (as opposed to raster based) drawing tools in Photoshop when creating my [very limited] artwork.

Hi, I have a question:
What is the common approach when using icons in an android app
(buttons, etc...) ?
Android offers these hdpi, ldpi and mdpi folders for images in
different resolutions. How good does this work for all different
displays?
Or is it more common to create the icons programmatically as
vectorgraphics? If yes: can you suggest any turorials regarding this
topic?

greets
