That's sound advice from Ronnie, if you use the NDK, target the stuff running 4.X on ARM processors, there's quite a lot you can do in a short amount of time. Supporting the landfill stuff running 2.2/2.3 or using Intel processors is a chronic waste of time.

I would say that in terms of difficulty for developers, Android is still better than Windows, as you have UNIX style package management to ensure your libraries are present OR to exclude devices which do not support those libraries.
