If your app was originally developed with Intel XDK, you can use the same signing key. If not, Google Play will not successfully update your application as the signing keys would be different. This would result in your application being considered different based on the signing key. In order to retrieve your Intel XDK Android app's signing key, email html5tools@intel.com with your email and  project name.
