  * PROBLEM DESCRIPTION:                                         *
  * On app startup, cordova.js logs errors such as "Error:       *
  * Unknown event action undefined". These errors do not have an *
  * impact for running the application, however they impacts     *
  * analytics. The issue stems from a not completely compatible  *
  * version of cordova.js being used for cordova-android. This   *
  * cordova.js was created using the updated Cordova Tools,      *
  * which is at a higher version than the version of             *
  * cordova-android.                                             *

  * RECOMMENDATION:                                              *
