During a recent live stream on my Twitch channel, we explored three different solutions to dependency injection on Android. A do it yourself approach, Koin, and Dagger Hilt. Let’s revisit them side by side, and look at the nuances between them, so we can determine which solution we want to use in our own applications.

In the last post, we demonstrated the different types of database relationships in Room. Next, we’re going to explore another niched concept of Room database management: database migrations. A migration is a way to handle moving from one version of a database to another as users update your application from the play store.

In this post, we’re going to explore some advanced concepts of the Room Persistence Library. Room is a great tool for storing complex data for your Android applications inside a SQLite database. As you begin to store more data in your applications though, it can be difficult to determine how to organize all of it.

We’re going to demistify database organization, and break down everything you need to know about database relationships in the Room library.

One of the many buzzwords thrown around the software devleopment community is Test Driven Development, or TDD. It is one of those phrases that sounds great when you say it - who wouldn’t want to have tests be their first priority when writing code?

However, it’s not always clear what TDD means. Does it mean you write code with testability in mind? Does it mean writing tests first? How can we write tests if we don’t have code to test? This post will answer all of those questions, and teach you how to implement TDD effectively on Android.

The Kotlin language used by Android developers all over the world is open source and available on GitHub. This means it’s open for contributions from anyone! It may, of course, feel very intimidating to contribute to a project of that size. Especially for those of us who are new to open source contributions.

The JetBrains team makes this process a lot less scary than it sounds. There are some beginner friendly ways to contribute to the language, and this post will walk you through every step.
