Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Users with Cordova Android apps running on Gingerbread or    *
  * Jelly Bean                                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * On Android Gingerbread and Jelly Bean, the JavaScript        *
  * 'Event' constructor is not supported in those old versions   *
  * of Android.                                                  *
  * One of the files used to fire an event in a MobileFirst      *
  * Platform Foundation with Cordova application uses this       *
  * constructor. When the event doesn't                          *
  * get initialized, no event fires, and so the application just *
  * hangs on the splashscreen. The solution is to use the old    *
  * way of handling events,                                      *
  * document.createEvent('Event'). This method is supported in   *
  * the older Android versions and also runs fine on the more    *
  * recent ones.                                                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *

Problem conclusion

• Android Gingerbread and Jelly Bean should be able to fire the
  event and move to the main screen.
  
  After installing the iFix, rebuild the application.
