Needs advanced Android networking example

[zmillman]

The Volley example is too simple for real-world usage.

I've been banging my head for two days against the problem of sending an HTTP request with parameters. The example doesn't provide enough guidance to help. (I'll eventually need headers too)

• Is there a way to do it with a Volley CustomRequest? I don't understand how to extend an abstract request and override the implemented methods (e.g. getParams())
• Is there a way to do it with OkHTTP instead? (I've been running into this issue: https://gist.github.com/zmillman/b04dbbcbb1cf0c80acf1 )
