Community Builder App (for smartphones)

Hello,
I'm wondering how to make a mobile app associated to the website of one of my customer, that uses Community Builder and a lot of its plugins (some from CB team, some other not, like UddeIM).
I have opened a new topic because I haven't found nothing concrete on Google nor on this forum.
Is there a kind of bridge (xml or so) to be able to manage CB subscription, profile, messages and so on from a mobile app? Maybe can be easier to build that app by Phonegap or another web-app framework, I am just trying to not build from scratches a web service to read and write in CB database, because it would take a lot of time.

Thanks for your time,
Kind regards.

Shouldn't really be necessary since CB is completely responsive and can just be viewed from the mobile browser. You'd miss out on push notifications unless you implemented the JS for those. You can reduce data usage by heavily compressing headers and using lazy loading for images; both doable using JCH Optimizer (we're using it here, works very well). Quickest solution is a small app that's just a wrapper for the website with maybe some custom client side caching of pages.

No, you would need to develop an extension or CB plugin to create a JSON endpoint API for handling all of your apps necessary requests.

That's basically what you'll have to do. You can try using CB Auto Actions for the endpoints I suppose though and at least reduce some of the workload since it can do PHP output for any action type now you can handle JSON outputs for various action types.

Ok many thanks for your answer.
You're right, CB is well browsed by mobile, currently on that website. Just the owner of that website whats this app, I've to implement also geo-location for users (using GPS) and a client side for UddeIM PMS with push notification.

I will publish here some solutions when I will do that, to let the community read, if somebody needs the same.

Greetings.
