pushing green BUILD button does nothing

If you push the green BUILD button after uploading your app and nothing happens (or you see the "build spinner" appear and then quickly disappear) you may have a project GUID conflict. This can be caused for a variety of reasons:

• you own multiple accounts that have projects with the same name
• you have multiple projects (with different names) that were copied from the same original project
• other security and authentication upgrade effects

The simplest solution to this problem is to:

• log into the Intel XDK App Center with your XDK userid and password
• delete the problem app from your App Center account (using the small garbage can icon)
• return to the XDK and try the build again (the XDK should automatically push your project for the build)

The App Center is where your projects are queued for use with the Test and Build tabs. Find the app that is not building, select it from the list to expand the control icons, and delete it from the App Center by pushing the small garbage can icon, as shown in the image below.
