Enabling code completion for Cordova android plugins

Hi There,

This is my first post on the forum, so hope I make sense :)

Well, I worked with Intellij for some years already, but now I started using Intellij for developing Cordova / Ionic apps.. All works very well, installed the cordova / phonegap plugin and quickly up and running.
But I cannot find a guide to enable code completion for when writing a custom Cordova Android plugin. The editor recognizes it as Java, but thats it.
Google only delivers me solutions for when using Eclipse, but intellij is a personal favorite, so that is a no-go.

Does anybody have it enabled, or know a workaround?

Many thanks!
