App Launch Screen

The app splash screen is the brief introductory screen that appears as the app loads after the user has just opened the app.

When the application is launched, Main Activity sends an intent to the Splash Activity, which displays the App Logo for 2000 milliseconds, from where the control comes back to the Main Activity. 




 The MainActivity consists of three options:

  1. Login:
    Users can log in using their Username. The user is directed to the Login Activity for authentication. The User first selects what type of user (i.e., Customer or Vendor) in the Spinner on the Login page. The Username for the customer would be their PhoneNumber, and for the Vendor, it would be their OutletName. Once the user clicks on the Login button, we verify if such an account with the given Username exists in the Database or not. If it doesn't exist, we display a Toast message saying, "No Account found". If the username is valid, then we verify the Password entered by the User by comparing it with the corresponding Password to the Username stored in the Database. If it is valid, then the User is redirected to their respective pages. 
  2. Register: New users can register by entering their information. Their account gets created upon submitting the registration form.
    The new user fills out their e-mail ID, mobile number, and Password. They will select the type of user in a spinner. If the type of user is a vendor, they have to add a URL of the picture of their food outlet. Then on clicking register, a new account is created.
  3. Login using Mobile Number: Users can alternatively log in using their mobile numbers also.
    We've used Firebase Authentication for this feature. The user enters their Phone Number, after which we verify if the Phone Number exists in the Database or not. If it exists, then an OTP is sent to their Phone Number by Firebase, and upon entering the correct OTP, the user is logged in and redirected to their respective page.

Languages and Applications Used

We will be detailing the software, languages and frameworks used to build the app: Android Studio:  It is the official integrated development environment(IDE) for Android application development. It incorporates various code editing and developer tools for a smooth and user-friendly user experience. It also has various options to run and debug code. Android Studio uses a build automation tool known as Gradle for compiling, linking and packaging the code. We had learnt to use Android Studio as a part of our course. Java : Java is a general purpose programming language which provides object oriented programming concepts like encapsulation and inheritance. We used Java for Backend programming. XML : XML stands for eXtensible Markup Language. It is generally used to develop web pages and web applications. XML has advantages like letting the user make their own descriptive tags based on his/her needs. We used XML for frontend programming.              ...

App Features(Vendor)

Here we talk about the Vendor's side of the app:  The Vendor Homepage contains a fragment that displays the corresponding layout of the item clicked in the sidebar. As soon as the vendor is logged in OutletMenu Fragment is called which displays the menu of the vendor's outlet, where the vendor and add, update and delete items from his menu. Based on the customer's requirements and usability, we have developed an exclusive set of fragments and an activity. OutletMenu: This fragment will be called default after the vendor is logged in. It displays the menu of the vendor's outlet. It contains a recycler view, which populates itself using outletMenu_adapter by querying the Menu corresponding to the vendor's outlet in the Database using Firebase UI. The vendor also has the option to edit and delete items from the existing menu.

As soon as the customer is logged in OutletList Fragment is called which displays the list of outlets present, where clicking on a particular outlet, will take them to the particular menu of the outlet. We've used Firebase UI in all fragments. Firebase UI is a class provided by Firebase SDK to make a query in the database to fetch appropriate data. Based on the customer's requirements and usability, we have developed an exclusive set of fragments. OutletList: This fragment will be called after the user is logged in. It will consist of a list of eateries that are open at any given time. It contains a recycler view, which populates itself using outletList_adapter by querying the List of Vendors in the Database using Firebase UI.  OutletMenu: On selecting one of the outlets, this fragment is called which di...
