Understanding Different Gradle Caches for Android Projects, part 1.

There are several ways Gradle stores information between builds to drastically reduce subsequent build times. You may be familiar with some of these methods, but what’s important is that they build upon each other gradually improving build speed. If you are only benefiting from one, then you have something to gain by also looking into the others.

This update, in version 24.2.0, meant that an app no longer needed to depend on the entire support-v4 library and could instead depend on only those sub libraries that it needed.

Until now I have yet to implement this update on any of my work or personal projects. This week as part of a general dependency audit, we decided to split up our support-v4 dependencies.
