Hi Ajith,
Please confirm us the Android SDK whether installed or not in your machine. If it's installed please share the screenshot of the Android SDK installed location. If it’s not installed, please install it using the steps from the link and try to create the Syncfusion Xamarin project.
If still you are facing the issue, to check further on the reported issue with our Xamarin Project Template, kindly follow the steps suggested in the below KB article link and send us the zip file which consists of complete Syncfusion Installer logs generated by our tool.
Regards,
Ganesan Rengasamy.
