title: Do I know if I need Multi-Dex enabled? (ClassNotFoundException)
body: <p>Suddenly and seemingly for no reason at all, the following error starts presenting itself. After fighting it all day, I discovered enabling Multi-Dex resolved it. Is this error potentially caused by my breaching the 64k reference threshold?</p>

  <p>Somewhere I can see the count of references? How do I know if I surpassed this - in VS specifically?</p>
