Comment 1 Marek Habersack 2017-04-21 12:52:23 UTC
Could you provide a small app which reproduces the issue? It's impossible to diagnose it based solely on the provided stack trace. Thanks!
Comment 2 anton.duzenko@gmail.com 2017-04-23 19:29:20 UTC
I can't repeat this on demand.
This happens on user's device and developer console report is all I have.
Comment 3 Marek Habersack 2017-04-24 14:42:13 UTC
@Anton, can you change your GC bridge as described https://bugzilla.xamarin.com/show_bug.cgi?id=51651#c2 and see if that helps the user who's getting the exception?
Comment 4 anton.duzenko@gmail.com 2017-04-24 14:52:40 UTC
Change my GC bridge to what value?
As for user I don't know if they're still using the app or have uninstalled it already because of all the crashes
Comment 5 anton.duzenko@gmail.com 2017-04-24 14:53:26 UTC
Can you provide any explanation on this particular crash - what does it mean and why does it happen at all?
Comment 6 Marek Habersack 2017-04-24 14:57:17 UTC
@anton Change the GC bridge to the one you're not currently using (as per https://developer.xamarin.com/guides/android/advanced_topics/garbage_collection/#GC_Bridge_Options). We don't know what the crash means, we suspect it has to do with the GC bridge in that it loses synchronization between the .NET and Java garbage collectors - hence the request to try another GC bridge. 

Another option is that there's a premature .Dispose() call on one of your objects (on the .NET side)

However there's not enough data for us to really know what's going on at this point.
