Can someone give detailed steps on how to add ionic keyboard in IBM worklight for hybrid application?
Followed below steps but getting error like “cannot read property ‘keyboard’ of undefined”

  1. downloaded plugin from https://github.com/driftyco/ionic-plugin-keyboard
  2. added keyboard.java in to app/androd/native/src
  3. modified android/res/xml/config.xml


  4. added keyboard.js in app/common/js folder and changed exe to codova.exe
  5. added keyboard.js reference in index.html as well
