If you are using the Syncfusion library together with Xamarin.Forms > 3.4 you should definitely continue to read.
Since the new release of Xamarin.Form 3.5, if you try to use the Syncfusion Listview (SfListView) in Release mode on Android, your app will crash.
In this moment there are two things that you can do:
- Use a version of Xamarin.Forms < 3.5
- Set the Linking to None (in this case your final APK will be bigger than usual).
Unless you are using some of the new features of Xamarin.Forms > 3.4, I’d suggest you to continue to use Xamarin.Forms 3.4 otherwise in you Android project, set the Linking to None and it will solve your problem.
I will update this post, as soon as Synfusion and Xamarin will solve this massive issue.
Meanwhile you can follow the progress of this bug here: https://github.com/xamarin/Xamarin.Forms/issues/5288
