title: Android Studio 3.x: error: cannot find symbol class GlideApp
body: <p>I updated Android Studio from 2.x to 3.x last week end. The project migration was perfect, build was great. And now, from 2 hours, I can't explain why, I can't build, I have this error on Glide now:</p>
  
  <blockquote>
    <p>Error:(26, 22) error: cannot find symbol class GlideApp</p>
  </blockquote>
  
  <p>All was good before, I didn't change anything (gradle or configuration), and now this error appears...</p>
  
  <p>For information about Glide, in my Gradle:</p>
  
  <pre><code>annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0-RC1'
  compile 'com.github.bumptech.glide:glide:4.0.0-RC1'
  compile 'com.github.bumptech.glide:okhttp3-integration:4.0.0-RC1'
  </code></pre>
  
  <p>The GlideApp file is generated automatically (I checked it).</p>
  
  <p>So, it's a crazy situation. Thank you very much guys!</p>
