Android: How-To create an app that pulls Album Art?

Question

Where would I get started to create an app that would grab your Album Art based on Album or Artist of the mp3 from the internet (ie. via amazon, play.com, etc..)?

I would likely be using Eclipse.

Answer 1

 Cusor cur = getContentResolver().query(Albums.EXTERNAL_CONTENT_URI, new String[] {Albums.ALBUM_ART}, Albums._ID + "=?", new String[] {albumid}, null);

Album Artist is still undocumented and not available before 2.3.3, I believe.
