A quick google on "Sprite animation android" would yield alot of nice answers.
However, since you mentioned that most were beyond your level of understanding, I suggest you look at the following article on sprites first: http://www.rpgrevolution.com/tutorial/rough-guide-to-sprite-animation_107.html
In short, the computer would divide a sprite sheet into many frames, and cycle through the frames repeatedly to simulate an animation effect.
The best way is to simply follow through a tutorial. You might not understand it at first, but copying and pasting codes helps in understanding as well.
