SharePoint Hosted app Custom newform

Question

I need to add a custom form (new, view and display forms) in a SharePoint Hosted app. I did follow these two articles article1 and article2.

Steps so far

• Created a SharePoint App project
• Added a custom list (Employee) to the app
• Added a custom new form and set the deployment type of the aspx to element file

• Added the following line in the list schema.xml file

  '<'Form Type="NewForm" Url="NewEmployee.aspx" Path="NewEmployee.aspx" WebPartZoneID="Main"Template="NewEmployee.aspx"/>'

  When I change the original form tag to the one shown above as suggested by the solution successfully builds but fails during installation.

The error in the Output window is as below

App installation encountered the following errors: 05/04/2017 00:12:02
