title: Android: Class Not Found runtime exception - release build only
body: <p>We have an app that has had several version on Google Play and has been working fine.  The latest updated causes a runtime error "Class not found" for our main activity.  The activity is called 'Home'.</p>
  
  <p>The runtime error does NOT occur on a debug build, only as release build.</p>
  
  <p>The activity has not changed for several updates, but suddenly has started raising these runtime errors on start-up.</p>
  
  <p>Cheers,
  Peter</p>
