问题 I'm writing a cross platform application using Mvvmcross, Mono for Android and MonoTouch. In the Java Android app I am porting I used ACRA to provide crash reports and ad-hoc reports.

This would destroy the portability of it. I'm searching right now a workaround and cause i'm no expert on mvvm i need help. I started to do some new
