I am working on a business accounting app in android, which will contain information like Company Details, Products, their prices, transactions, etc . Hence My server will have many MySql tables, I want my android app to communicate with the server for authentication, retrieve information , store information quickly, CRUD etc.
I have googled about PHP , JSon, and REST, but I am unable to get an example close to my needs.
What are the ways through which communication can be carried out from android app as fast as possible?
If PHP and JSON are the solution, then how do I implement it in Android? Any Examples?
