Tech News Aggregator

Description

An app that aggregates tech news from different sites and displays them all in one unified news feed. The app should have a list of possible news sites to which the user can subscribe as well as support for multiple users (locally). Each user will be displayed only news from his subscription list. These preferences should be stored using SharedPreferences. The app should also have a welcome screen. (EX. https://feeder.co/knowledge-base/rss-content/rss-lists-popular-and-useful-rss-feeds/)

Architecture

Screens

• WelcomeScreen - a screen with the logo of the app and some text
• SelectUserScreen - a screen where you can create or choose an existing user profile
• UserSettingsScreen - a screen used for both creating and updating user settings
• NewsScreen - where all the news will be fetched and parsed and displayed

User Bloc

Events based on flows

• NormalUserFlow: UserSelection, UserFeedDisplay
• FirstEntryFlow: UserSelection, UserCreation, UserSelection, UserFeedDisplay
• UpdateListFlow: UserSelection, UserFeedDisplay, UserUpdateList, UserFeedDisplay

Unique events:

["UserSelection", "UserFeedDisplay", "UserCreation", "UserUpdateList"]

States based on events

• SelectUserState - ready to select users from the list
• FetchUserFeedState - actively fetching the RSS feed
• CreateUserState - adding a new user to the list and set of preferences
• UpdateUserState - update the list of user feed sites

Implementation

Shared Preferences

{
    "users": [ "BZV", "Test1", "Test2", "Test3", "Test4" ],
    "BZV": ["Aramco", "F1", "Motorsport", "Hello"],
    "Test1": ["Love","Netflix"]
}

Restrictions

The application can have up to 5 users

Logic

First screen display

• If it's first time you enter the application (meaning users is empty --> you will be shown a welcome screen)
• If it's not your first time, you will be shown WelcomeScreen and moved after 0.5s to the SelectUserScreen

Create User

• If we have less then 5 users, we can add a new one, being a CreateUser event dispatched
