Hi Emil,
Thank you for contacting Syncfusion support.
We have checked the reported issue “Exception throws when ScrollToRowIndex is used” with the latest SfListView version(v 15.3.0.33) at our sample in both SfListView’s Horizontal and Vertical orientation. In the sample, we have scrolled to desired index in a button event at runtime using ScrollToRowIndex method but we did not face any issue as reported. We suspect that the issue occur might due to SfListView assemblies may not added or referenced properly in Android renderer project.
So, we recommend you to please ensure that assemblies are referred in both PCL and Android renderer project and for more information please refer the following UG documentation link.
For your reference, we have attached the ensured sample with latest SfListView version at our end and you can download it from the below link.
Please let us know if you require further assistance.
Regards,
Dinesh Babu Yadav
