Welcome to ONE Max Rep!

This is my interview sample app where I utilized the newest technologies available for Android:

• Compose
• Hilt for dependency injection.
• Material 3
• Flow
• MVI as a Desing pattern
• I've also decided to stick with MPAndroidChart as recommended.

How to setup

Clone the repository and open it with Android Studio Iguana (Build #AI-232.10300.40.2321.11668458).

• Let the pakages to sync.
• Click the play/debug button.

In case you encounter an error, simply invalidate the caches and restart (File > Invalidate Caches).

How to add new workout data

In the assets folder of the Android app, you'll find the same text file (workoutData.txt) shared in the assessment. Simply replace the content of the file or replace it in the file location with the same name.

If you want to change the name of the file, just update the constant WORKOUT_FILE_NAME located in the WorkoutDataSource:

private const val WORKOUT_FILE_NAME = "NewName.txt"

Architecture

As requested, I used MVI, which is MVVM-like but works with intents (States). It involves Views and ViewModels. I chose this pattern because it integrates better with Jetpack Compose. We follow the common Android Architecture:

• Hilt
  • Manages the injection of viewmodels, data sources, and repositories.
• DataSource
  • Handles data reading. The app could be improved by adding Room to implement some ADO (Android Data Objects).
• Repository
  • Defines the interface to implement the WorkoutRepository. This allows us to use an API or health data from services like Google Fit, Health Connect, etc.
• ViewModel
  • Creates UI States and reads data from the Repository.
  • Also handles route navigation from Compose by reading the required data using parameters.
• Screens
  • Renders the views in Compose.
• Navigation
  • Utilizes a List Pane. If you're using a tablet or a device with a large screen, the list will render in landscape, next to the selected RM.
• Coroutines
  • Using flow to read the data as states and also to prevent the UI to get locked.

Git Flow

I created my branches for different features and merged to main as I usually do on my daily basis.

Unit Testing

Added 5 scenarios to validate the formula and cover cases such as division by 0 and 0 repetitions.

Missing Features

• Android App Links
  • Even though routes are implemented, we can further improve the app by adding hosts to the manifest and implementing Universal Linking. Since we don't have a server to upload asset links, this is not necessary for now.
• Modularization
  • I created a single module (App), but internally structured the different folders for future modularization if needed.
• Synchronization
  • Since there aren't many data sources, synchronization isn't necessary.

UI Testing

I plan to add tests during the weekend. Currently, I have some releases to handle at my current company, and I cannot delay them.
