title: AppCompatTextView could not be instantiated
body: <p>I am having problems figuring out what to do to solve this error.<br>
  I tried invalidating caches/restart, freed up disk space and reinstalling Android Studio.</p>
  
  <pre><code>The following classes could not be instantiated:
      - android.support.v7.widget.AppCompatTextView(Open Class, Show Exception, Clear Cache)
  Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE.If this is an unexpected error you can also
  try to build the project, then manually refresh the layout.Exception Details java.lang.NullPointerException
