Reproduction Link

Any sort of reproduction, even if it causes crashes intermittently, would be extremely helpful here.

I do not have any reproduce steps, It happened sporadically, This was happened 11 times in last two months, Got it from Hockey report.

I just thought I'd reference possibly duplicate bugs:

#2004
#2041
#2317 (https://bugzilla.xamarin.com/show_bug.cgi?id=57789)

I do realise ObjectDisposedException is general enough that unrelated issues could cause them. However all three above are also Android.Graphics.Bitmap and two of them also happen in ButtonBackgroundTracker while a page is being disposed.

[mtarros]

I had the same issue and found out that it was caused by having a button in a list view cell and the table had a long press. I got around it by changing the button to a tap gesture.

[balaameex]

Hi mtarros,

Are you able to reproduce your issue consistently? and able to resolve?, My issue is happening intermittently and unable to reproduce again and it is happening sporadically.

[mtarros]

It would happen intermittently also, but we did work out the steps to repeat the issue. I think it was just repeating browsing between two screens.

Removing the button from the list view cell and replacing it with an image and a tap gesture solved the issue.

[mfeingol]

I'm seeing something fairly similar inside a Xamarin Forms app on Android. The affected page has the same layout mentioned by @mtarros: a grouped listview containing items with buttons.

The issue is somewhat difficult to reproduce, but for me it happens when something on the page causes the buttons to be destroyed and recreated. E.g. if you use a grouping listview and remove / re-add items to a group when the group header is tapped (which leads to an expand/collapse effect), you'll be inducing the repro scenario.

[PureWeen]

I created a central issue for this type of exception
#2829

And I'm going to close this one for now
If you don't feel like the issue I created represents the problem here just let me know and we can reopen

[PureWeen]

#3459

in the upcoming 3.2 should resolve this
