CodePath Android Cliffnotes
I found this great resource on github about android development. Its goal is to become the central crowd sourced resource for complete and up-to-date Android content and tutorials.
Have you ever been frustrated searching bing or google looking for a solution to your problem and all you can find is outdated deprecated code examples. This central crowd sourced resource strives to fix just that.
The creators of this resources leave it opensource and encourage you to join in and add content. This is a great way to share your knowledge.
You can find it here.
