body: <p>I want to add EmojiCompat to my app. However, the project cannot be built due to a warning :</p>

  <p>This layout XML <em>input_method_extract_view.xml</em> is provided by the appcompat library and I have tried in the EmojiCompat demo project which can build successfully.</p>
  
  <ul>
  <li>build tool version 26.0.1</li>
  <li>appcompat version 26.0.1</li>
  <li>Kotlin version 1.1.4-3</li>
  </ul>
  
  <p>I have tried to build with the default one in Android Studio and JRebel for Android, both of them build failed.</p>
