title: getting stack trace for app that was not installed through Google Play
body: <p>I sent my app to several users via Email. It can be installed like this on several test user devices quite easily. </p>
  
  <p>Now I need to get the stack trace from a crash of the app similar to the trace that is available for apps sold through Google Play.</p>
  
  <p>Are there any "comfortable" possibilities?</p>
  
  <p>While I have my own logging which I write to a log file so the test users can send me my own created logs, I certainly cannot catch all crash situations myself.</p>
  
  <p>Many thanks!</p>
