Android app improvement; push notifications and account creation

Working on the first version of our app, we would like to improve it in several ways: 1) Account Creation For now, users can log in from the app. But we would like them to be able to create an account without having to visit our website. So below the login form, there should be a link/button “New Challenger? Create an account!” 2) Push Notifications Every user of the app will receive personnalized or general notifications, clicking on the notification will bring them to a screen of the app, or to a web url. Every notification will have an icon depending on the nature of the notification (url of the image from the server) 3) Duplication of the current App We need to use our current app but with a different name and logo; different url for the API and language menu (with default as android language). Text in the app will be translated to french and spanish. (I'll give you the translation).
