How to integrate native app code in ionic1 codova project?

I have AR (Augmented reality) demo app in native code both iOS and Android. I want to integrate this app in my ionic cordova project. My Ionic project is build in Ionic v1 with Cordova and Angular 1.5.3. As I’m new to ionic development I would seek proper guidance and help in this forum. Attached my ionic info.

Thanks in advance.
