@jonan @fadils What is your option on dropping the maven and eclipse support and using a clean gradle build structure like mentioned here: http://developer.android.com/tools/building/configuring-gradle.html ?

This is solid, and much needed. With the number of changes though, it's going to break a lot of existing pull requests. Need to think about if it's better to bite the bullet and do this now, or try to resolve those first (but then you'd probably have to close and re-open after those updates). Leaning towards the latter, but since the work is on you for this I want to see what you think as well @larsgrefer

[larsgrefer]

I think we should wait until the most mergeable pull requests are merged.
But in the meantime we can merge at least #754

I try to rebase this whenever needed so it stays mergeable

[ZacSweers]

I'd rather just do them all together in one pull request, rather than have the same commit appear in both. I've commented/addressed most of the open PRs right now, so waiting for responses and hopefully should get them resolved soon.

[larsgrefer]

Okay, but if you'd merge #754 i'll remove the commit from this PR

[ZacSweers]

Still rather do them together in this pull request, please just wait.

[ZacSweers]

Pulling the trigger on this. The other PRs I've responded to have had enough time
