## AI overview

A hands-on tutorial covering the Android build pipeline with ProGuard and R8. It walks through compiling Java or Kotlin source code, using Android Build Tools, and examining generated bytecode.

## Source excerpt

This blog post is the second in a series to teach about the build tools ProGuard and R8, and the first in the hands-on portion of the series. In the first post I talked about the Android Build Pipeline. In this blog, I would like to actually reinforce those concepts with hands on exercises. If you haven't read the first blog on this topic, this is part two in that series, so I highly suggest going back and understanding that material first.
