i am planning to develop a native mobile Android App for WooCommerce shops.
I had a look at their REST API documentation here: http://docs.woocommercev2.apiary.io/ I
I would suggest this steps
First thing you can Enable Api for woocommerce from the backend – http://docs.woothemes.com/document/woocommerce-rest-api/
https://www.npmjs.com/package/woocommerce use this link, which has all the methods to interacting with woocommerce. Otherwise using lightweight middleware, it help to connect woocommerce server & return JSON data to your app.
Write a service using ionic framework and talk to your thin middleware client. Do not forget to cache the data (using local storage), so that you don’t hit the server all the time. - Contus M Comm
