body: <p>I upgraded my <code>android studio to 3.4 canary</code> and now I cannot successfully build anymore due to the following error: </p>
  
  <pre><code>The given artifact contains a string literal with a package reference 'android.support.v4.content' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.
  </code></pre>
  
  <p>More details:</p>
  
  <pre><code>Caused by: java.lang.RuntimeException: Failed to transform '.gradle/caches/modules-2/files-2.1/com.jakewharton/butterknife-compiler/9.0.0-SNAPSHOT/732f93940c74cf32a7c5ddcc5ef66e53be052352/butterknife-compiler-9.0.0-SNAPSHOT.jar' using Jetifier.

  </code></pre>
  
  <p>Clearly, its something to do with <code>Butterknife, androidx and Jetifier</code></p>
  
  <p>Do anybody know how to fix this?</p>
