Hi Mirza,
Thank you for using Syncfusion products.
We have already fixed the reported issue with SfTabView "Java.Lang.NoSuchMethodError: no method with name='setClipToOutline' signature='(Z)V' in class Landroid/view/View;" at our side and the fix will be available in our upcoming Volume 2 SP2 release which will be rolled out by the end of August 2018.
Regards,
Paul Anderson
