Answer 1

Worklight/MobileFirst < 8.0 beta do not have proper support for Cordova plug-ins.

As you go through the suggested guide, make sure to also review the following, providing the required additional steps to take: https://mobilefirstplatform.ibmcloud.com/blog/2015/08/03/integrating-3rd-party-cordova-plug-ins/

Namely:

• Modifying files so that the plug-in will be recognized
• Using Ant to keep the plug-in integrity post-Worklight build (which will otherwise break it)
