Description

We often receive crash reports from our Android users but (sorry!) we could never really replicate it in a controlled test environment, neither do we have any insight from our users on when/how the crash occurs...
Could you shed some light on where to look for investigating this issue any further?
Android: 10
Android Build: QKQ1.190910.002

          Hi, @inimirpaz - thank you for submitting this issue! Are you able to share your project or a sample project that can help us get a sense of your general project structure, what controls you're using, etc? In particular, I'm curious about any code you might have related to state handling.




    

Also, do you have information on which devices and versions of Android that users are experiencing this crash on? And what version of XF are you using? Thanks :)
          Hi, @rachelkang thanks for your reply. Since we have not been able to repro this in any smaller project (not sure what to look for for reproducing this issue) I am not able to provide any sample project. We do not have any explicit Android state handling code beside the one we cited above from the StackOverflow post.
We are using Xamarin Forms 5 (we have been having this issue at least for every 5 release so far, I could check if the issue was there even with 4.8).
Here are the latest few errors we could find from our users (note that the last one is slightly different):

Is there anything we could do for making this issue more "debugable"?

EDIT: Yes, this issue was already present when we were using XF 4.8.0.1560 (or prior to that).
          This is also happening to us:

          @inimirpaz about that linked stackoverflow post that didn't work for you. There are other components that are subclasses from CompoundButton. Did you create renderers for all of them to test? Because the fix in that post is only for switches.
Known direct subclasses: CheckBox, RadioButton, Switch, ToggleButton.

Hi @romerotg

I created renderers for the Switch control only, I may try creating one for Checkboxes as well (I have no radios nor toggles).

  Completely doesn't work, crashes, or is unusably slow, has no obvious workaround; occurs less often
