Hi Halil,
Thank you for contacting Syncfusion support.
We have checked and we can able to reproduce the reported issue "Application is crashed while creating cell template view if we debug the shared application" in Xamarin.Forms Android. Currently, we are validating this issue, we will update you the further details on or before June 25, 2019. We appreciate your patience until then.
Regards,
Subburaj Pandian V
