Setting Up Android Modules with Koin

Previously, I experimented setting up Dagger 2 on an Android project with multiple modules. You could find that article below:

Setting Up Android Modules With Dagger 2

Since then, I’ve wondered how Koin would work for a multi-module Android project. The topic is debated on Reddit as a service locator instead of dependency injection. Regardless, they both are pretty similar and could achieve the same thing if done properly.

Let’s look at how it is done here.

Project Assumptions

Here’s how we’ll set up our simple project:

• There are three activities, where MainActivity could launch FeatureOneActivity or FeatureTwoActivity
• Each of the activities has its own dependency injected to it
• Each of the dependencies is injected with a singleton network and repository (i.e., the same copy is injected to all dependencies)
