During the development of Mr. Dandelion I came across a lot of pages with useful resources. Sprites to download, music and information about marketing your game.

As a total n00b in game industry, I enjoyed working on my game until I realized how hard it is to get it out there. One of the pages I found helped me a lot because it offers big lists (literaly) of articles and sources useful for developers of every game genre and platform out there.

I can highly recommend going through the big lists at Pixel Prospector. They don't list that many resources for Android Game Development nor for AndEngine, but a lot of articles are applicable generaly.
