Hello, I only changed one tiny bit of your code in the WorkflowdetailsFragment class. Look at this gist:
https://gist.github.com/ianwdunlop/2c3615e9094827fabd83 You might be running into issues with the http connection closing during debug mode which I encountered yesterday. It will cause a broken pipe exception. You may have to run the app as normal when testing this or maybe move your breakpoints to after the connection has sent the request.
