Learn a bit of Java first if you don't know it. Try thenewboston's tutorials on youtube. You can also find some Android tutorials on youtube.

Also go to anddev.org, androidsnippets.com and p-xr.com for code snippets.

I prefer learning with the video tutorials a lot more. It's too bad there aren't too many of them right now, but you can find a couple of decent series on Youtube. Do the projects in the same time with them. There are also several books for beginners. Just google top android books for beginners, or something like that.
