Hi,

I think u have missed setting the text property of TextView UI element .Set the text property and deploy and run the application.

Hi,

It is quite hard to find out the problem by seeing only exception trace. I think you are missing one of the mandatory elelments' properties or setting them to invalid values. Please check and let me know if you can give more information.

Hi

This error may occurs due to incorrect colspan settings in the layoutcontainer:gridlayout

Thanks
