The client is requesting the implementation of an Android App using Rest Api. I implemented the app using Cordova and it has a connection to the company's server using JSON. The server contains various PHP files which will be executed to retrieve data from database and send it to app, sending email to the user or doing other stuff. I don't use web service because there is no web app. The server only store PHP files and the database, which are accesible from Android app. In this case, is it possible to use Rest? and if the answer is yes. Is it recommendable?
Thanks in advance
