Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

Hi!

This test rule is now in the 'test-rules' support repository. Use that one!

Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. To use the support version of these attributes, remove the android namespace.  For instance, "android:colorControlNormal" becomes "colorControlNormal".  These attributes will be propagated to their corresponding attributes within the android namespace for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.

All Clickable Views:
-----------
* ripple effect (Lollipop only) -- "colorControlHighlight"

Status Bar:
------------
* background (Lollipop only) - "colorPrimaryDark"
