Crash when scrolling on Android 7.x (problem seen in example project too)

Hi Daniel,

I have a problem with the FlowListView in my app. On Android 4.4 and Android 6 (Samsung galaxy s5) it works flawlessly, but on Android Nougat ( 7.x) my app crashes when scrolling after the screen has been filled with images. I also reproduced the problem in your sample application, in the Update items grouped example.

What can I do to fix this?

Here there is the stack trace:

Maybe is it a problem with grouping Lists? I couldn’t reproduce in the Simple Gallery section

EDIT: I think it’s the grouping, because it’s giving this error just in that examples! EDIT2: It seems an unresolved bug of Xamarin Forms with android 7, as noticed. https://bugzilla.xamarin.com/show_bug.cgi?id=51429 https://bugzilla.xamarin.com/show_bug.cgi?id=51645 https://bugzilla.xamarin.com/show_bug.cgi?id=51704

@daniel-luberda Let’s hope! Thank you both for your time!

There were several bugs, maybe they’re fixed in Xamarin.Forms 2.4?
