Is there a good website to share and optimize code together?

Question

Recently I am working on Android app development, and also I did iOS app before. I am not good at Android so far, so sometimes I found the app is kind lagging, thought stackoverflow.com is very nice place to share and found the bug, but I would like to ask if there are some websites that I can share all codes and details about the app, and there are also some programmers there they can read and point it out what's wrong with my app? I don't know if this question is legal here, just think it's good to have one and learn more..

Answer 1

You can post code and get it reviewed at https://codereview.stackexchange.com/

Answer 2

The best solution would probably be to push your projects to a site like Github where there's a great infrastructure in place to allow people to collaborate with you.

Asking people to do so is a different issue, but probably best achieved through posts on XDA-developers and equivalent forums.
