This project is for a tertiary institution. Apps will be used by students, and push notifications need to be sent to specific students (even individually). The actual app is already developed in PHP. What I need is the Android shell that allows a student to register with a student number and ID number. Upon registration, the student number and ID number together with the device token must be saved on a mysql database for identification purposes. Thereafter the app must only open the php app (like a website) inside the Android app.
