DeviceDiagnostics

This is a placeholder for the refurb project
Once we have a name and a repo in the android codebase, this is redundant

Get the topic:

https://googleplex-android-review.git.corp.google.com/q/topic:DeviceDiagnostics

Add a folder packages/apps/DeviceDiagnostics to your android tree

Pull this git to it

You should now be able to build Android and see a new setting:

System/Reset options/Device Diagnostics

The first screen is still part of settings, but once you press the button,
you are running the DeviceDiagnostics app from system

You can develop in one of two ways:

Edit the files, rebuild Android, flash (or use adb remount and sync)

Alternatively you can remove DeviceDiagnostics from the device (roll back the change
in device/google/shusky) and then simply use Android Studio to edit/test the
apk. This is dramatically faster. However, you should test to make sure you
haven't broken Android development before uploading.
