title: How to get 'android.enableR8=true' to pass without warning?
body: <p>I added the new setting:</p>
  <pre><code>android.enableR8 = true 
  </code></pre>
  <p>to my Gradle file but I got the following warning from the compiler</p>
  <pre><code>WARNING: The option setting 'android.enableR8=true' is experimental and unsupported.
  </code></pre>
  <p>any suggestions on how to get this to work?</p>
