Add a request factory based on okhttpclient

[stephanenicolas]

Add a request factory based on okhttpclient if okhttpclient is available on the classpath. #10

This pull requests add very little code and provides an okhttp based implementation of spring android. This http engine has several advantages :

• SPDY support allows all requests to the same host to share a socket.
• Connection pooling reduces request latency (if SPDY isn’t available).
• Transparent GZIP shrinks download sizes.
• Response caching avoids the network completely for repeat requests.

The pull requests is simple and is tested (thx to your tests).

I also updated the android maven plugin version to get things working with latest android SDK.

Hmm. That's strange, but it appears some of our internal people are looking into it already. For legal reasons, we have to use that form. But once you submit it, it's good forever and you can contribute to any of Spring's projects. I'll reply when it's working again.

Thanks Roy. Waiting for it.

Ok, thanks! I received a corresponding email with the details.

[stephanenicolas]

My pleasure Roy. But If I may, I believe it would be more motivating for
contributors if the release cycle of Spring Android was faster. I have the
feeling to have submitted that PR almost a year ago. Things go much faster
usually on the mobile side.

Yes, agreed. This project hasn't received the necessary attention over the last year. We're working to remedy that, and having active contributors would make a big difference.

I've spent some time today working through the pull request. Take a look at this commit on my branch and let me know if you have any more feedback. I updated to OkHttp 2.0 in the process and did some formatting and cleanup. I'm concerned about creating a new OkUrlFactory each time, but I'm willing to push this version for a first iteration. I've tested on APIs 7, 8, 10, 13, 14, 15, 16, 17, 18, and 19. It fails on 7 and 8 because OkHttp isn't supported on those.

[royclarkson]

I forgot to mention that I removed OkHttp as the default. I'd like to get feedback on its usage before making that change. But ultimately, I think it's probably the right move.

[royclarkson]

I've merged my modifications of your pull request into master. Thanks, Stéphane!

Hi @royclarkson , sorry for the delay. I reviewed the commit and it works fine for me. Thx to have merged this into Spring Android.
