Adding these proguard rules resolved issue for me.

Hello

I have similliar issue with RequestListActivity showing up but not loading requests on Android. In my case this issue only happens in release mode of app, when application is in debug this RequestListActivity loads properly and shows requests, but when APK is made it gets stuck at loading. I think that most likely there are some issues with proguard rules.
