Tivi 📺

Tivi is a TV show tracking application which connects to Trakt.tv. It has been updated over the years to target a number of platforms, built upon Kotlin Multiplatform and Compose Multiplatform.

Platforms

Android

Tivi started out as an open source Android app, showcasing cutting technologies through its development. The codebase was transformed in late-2022 to be built upon Kotlin Multiplatform, allowing us to re-use a large proportion of the code across different platforms.

iOS

The iOS app is well maintained (the main developers uses it daily). To aid development time, most of the UIs are shared with the Android app, enabled through Compose Multiplatform.

Desktop JVM

Tivi is built for Desktop running as a Java app. Unfortunately we don’t have feature parity on the desktop target due to either missing APIs, or lack of priority by the maintainer to implement them. However the basics of the app do work.

Development Setup

Android and Desktop

Tivi is a standard Gradle project which can be opened in recent versions of Android Studio or IntelliJ.

• The Android application module is located at android-app/app/ (:android-app:app).
• The Desktop application module is located at desktop-app/ (:desktop-app).

iOS

The iOS project is setup as a typical Xcode project. It currently uses CocoaPods to manage dependencies, and therefore you’ll need to install this before opening the Xcode project.

Let's step through it:

Setup Ruby

We need Ruby for various dependencies, therefore we need a Ruby environment. I recommend using rbenv, but that's just a suggestion:

brew install rbenv

rbenv init

# Download Ruby 3.3.4 and set it as the global version
rbenv install 3.3.4
rbenv global 3.3.4

# Install bundler
gem install bundler

Xcode

We use the latest version of Xcode supported by Kotlin Multiplatform, which is defined in the .xcode-version file.

We enforce the Xcode version on CI, but locally you can use whatever version you want. The Xcodes.app application is a great way to install different versions.

Nearly there

After you have installed the dependencies, you can now pull down the dependencies:

cd /path/to/tivi/checkout

# Install all of the Ruby dependencies
bundle install

# Install pods
pod install --project-directory=ios-app/Tivi

Open the project in Xcode

Finally, we can open the project in Xcode. Open Xcode and then point it to the workspace file at: ios-app/Tivi/Tivi.xcworkspace.

Press Run and it should build!

Code style

This project uses ktlint, provided via the spotless gradle plugin, and the bundled project IntelliJ codestyle.

If you find that one of your pull reviews does not pass the CI server check due to a code style conflict, you can fix it by running: ./gradlew spotlessApply.

API keys

You need to supply API / client keys for the various services the app uses:

• Trakt.tv
• TMDb

You can find information about how to gain access via the relevant links.

When creating a Trakt API project, you need to set the OAuth redirect uri to app.tivi.debug://auth/oauth2callback for debug build types, or app.tivi://auth/oauth2callback for release build types.

Once you obtain the keys, you can set them in your ~/.gradle/gradle.properties:

# Get these from Trakt.tv
TIVI_TRAKT_CLIENT_ID=<insert>
TIVI_TRAKT_CLIENT_SECRET=<insert>

# Get this from TMDb
TIVI_TMDB_API_KEY=<insert>
