I've started developing for GAE (Google App Engine) and I want to build a REST API using Google Cloud SQL. I currently have a web app in App Engine that works well with Google Cloud SQL but I need to build an API to provide REST services for Android and iOS or any other technology capable of consume web-services.
I've read many docs in Google about Mobile Backend Starter, Endpoints, etc. I'm not pretty sure how to integrate with my existing Cloud SQL Database. I think I'm almost near to get what I need.
If someone knows a tutorial or documentation to achieve what I need, please share it in here.
Thanks!
