/* put this in your application's build.gradle after the android {} block
 * output is in this format: "<projectName>-<buildType>-v<versionName>-<versionCode>.apk"
 * e.g. "materiyolo-debug-v5.0.0-12345.apk"
 * also, supports injecting jenkins ci's build number into apk, if available
 * e.g. "materiyolo-debug-v5.0.0-12345-b6789.apk"
 * you must specify your versionName and versionCode in your build.gradle for this to work

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"
