General

Basics

Very simple Webview App that allows us to send push Notifications to users

→ Notifications based on firebase by google

→ Frontend needs javascript ↔ java interface, that submits DeviceID to backend, so that Push notifications can be send to one specific device. See Binding of javascript to app functions

Changes needed

Backend

• needs exta field in user-table for DeviceID (question: multiple ones?)
• Connect to google Firebase Server for sending Notifications

Frontend

check if user is in App (done by "angular.idDefined(Android)") - if so, call Android.getDeviceID() and send it to Backend.

• User service needs setDeviceID() and deleteDeviceID() fields
• Call User.setDeviceID() on login, and User.deleteDeviceID() on logout if "Android" variable is defined
