title: How to create RealmSchema for using production realm in instrumentation test?
body: <p>I want to debug an issue that might only happen on certain data.
  Therefore I want to use a specific Realm file in an AndroidTest.</p>
  
  <p>However, I get the <code>RealmMigrationNeededException</code> and can't add the classes to a module manually since I get an error saying that I can only add classes from this project. Is there any way around this? </p>
