Similar to your other reported issue(s), we will require more information (preferably exact reproduction steps and/or a reproduction project) in order to investigate this issue.
I really have no idea how to reproduce this, or any of the other issues I opened. I don't even know where in my app to start trying because the stack trace contains none of my code. But it is happening for sure out in production because these errors are all in insights. The jobject error has happened over a hundred times since Friday.
I am also seeing this in Insights, and I agree with Wessel. It doesn't seem possible to track down, reproduce, or create a minimal reproduction project since the Insights stack doesn't contain any non-Xamarin code.
Any tips on how to get more information on this?
Thank you for your bug report. As we have not received the information requested, we cannot properly triage your bug and are marking it resolved.
Xamarin Forms Team
I can reproduce this error...
We are running our app on a Samsung Tab A running Android 5.0.2.
Our form has some text boxes that if we fill one out (it has a validator on it as well using behaviors) and then open the picker, select a value and hit OK, it throws this exception. We cannot reproduce on any other table or emulator except for the Samsung Tab A.
This exception doesn't appear to occur in our code and happens in the mono libs inside of an implementation of android.content.idialoginterfaceonclicklistenerimplementor
