Description

Databinding has a CLI compiler that is in aosp (no artifact on maven.google.com yet). It is only two classes, but it allows ingesting layout xml files and outputting the metadata required by the databinding annotation processor to work correctly.

By using a genrule to pre-process the resources of a module, databinding support can be added in buck/okbuck

Contributor guide

Research direction
Study the Android databinding compiler from AOSP, understand how it processes layout XML files, and learn how okbuck generates build rules. Implement a genrule in okbuck to invoke the databinding compiler and integrate the output into the annotation processing step.
