Hi! Lets meet Betty...

Betty is actually an app, for checking Bookmakers best odds. Android app, written in Kotlin and it uses Jetpack Compose for UI. Right now Betty is only single screen, but in the future may add more features to it.

Setup

To run app:

git clone repo to Android studio
Get your own Api Key from Odds-Api-
Add your own Api Key to gradle.properties in this format

betty_api_access_key = "123456789012345678901234567890"
And run app in emulator or on physical device

Stack

MVVM architecture
Retrofit for pulling data from network
Room for persistence
Coroutines for threading
All Remote and Local logic handled in Repository
ViewModel handles logic between UI and Repository using Flows and Coroutines
Hilt for dependency injection
Using Lottie for animations
Workmanager fetches new list everyday
Notifications when new data is fetched

Screens - Features

Main Screen

Main Screen shows Best Odds form Ods-Api.
All odds are displayed in LazyColumn.
Using Sticky Header in the list. List is split in 3 parts: High, Medium and Low chance of winning
Swipe down to refresh deletes all items from database and fetches new list
Repository flattens this big 4 layered DTO to small single data class Odd
Repository picks up best odds and those belonging to Williams Will (i use Williams Hill for betting if i do at all.. no time)
Progress bar of fetching data showing in Home screen
Snackbar shows if and error comes up
All results are saved in local database.
Workmanager constrains handles no internet connection

And i think that's all about Betty for now.

In the future will add:

Bookmaker chooser - probably by filtering getOddsFromLocal() flow
Sport chooser may ber useful for someone too
Option to show odds as a fraction not only decimal
Settings screen for managing notifications and work manager tasks

When all above is done i'll find Betty new home in Google Play Store

Any suggestions let me know.
