I recently got the following message after building/downloading a demo app with Cordova:
Apache Cordova 3.7 Recommended!
Your project does not target Apache Cordova 3.7 and might not run properly in this version of Telerik AppBuilder Companion App.
So far experiended in "BarcodeScanner - Version: 2.0.0 , Nov 27, 2015" and "Telerik Push Notifications - Version: 3.1.1 , Feb 24, 2016"
Just wanted to let you know this. The demo apps still works so far.
