In this episode, we talk to, Siggi Jonsson. Siggi helps guide us through the complex and often confusing world of Android app modularization. Our conversation will begin by shedding light on the importance of modularization, what triggers the need for breaking projects into multiple modules, and how modularization relates to team size, feature teams, and code ownership. This discussion is aimed at demystifying how and why developers often choose to modularize their applications.

As we move forward, we’ll dive into more advanced aspects of modularization, such as the challenges of scaling and the potential missteps in over-modularization. Drawing on real-world experiences, we’ll examine the red flags that signal a need for revising your modularization strategy. This part of our discussion will also highlight some specific tools and techniques that can help manage and visualize your project’s modularization, and Siggi will share his own experiences and insights into how these tools have assisted in his modularization strategy.

In the final part of the episode, we’ll touch on the benefits and strategies of proper modularization. Siggi will share practical advice on how to tackle big projects, fix issues with modularization, and make a smooth transition from monolithic to modular structures. We’ll also talk about some tools that can be handy in this process. Before closing, Siggi will offer his top tips for developers embarking on their modularization journey and share some valuable resources to help them. Siggi will also provide updates on his latest work and how listeners can reach out to him.

In this podcast episode, we have the pleasure to host Fred Porciúncula, a Google Developer Expert (GDE) known for his work with Kotlin Inject and his invaluable contributions to the Android development community. Fred offers his expertise on Dependency Injection (DI), Kotlin Multiplatform (KMP), and how they intersect.

We kick off the conversation by discussing Dependency Injection (DI), its importance, and the options available to developers, including Dagger, Hilt, Anvil, Koin, and Kotlin-Inject. Fred explains the use and impact of DI in the Kotlin Multiplatform (KMP) world, considering Dagger’s current lack of KMP support and debating whether one should use separate DI tools for Android apps and KMP components.

Delving further into Kotlin-Inject, we explore its features, usage, and how it differentiates itself from other DI solutions. Topics discussed include its unique handling of Scopes, its support of constructor injection, and its utility in building dependency graphs. Furthermore, we examine the timeless debate of Dependency Injection versus Service Locator.

Toward the end of the episode, Fred presents his thoughts on the advantages and disadvantages of exclusively using Kotlin-Inject throughout an application. We also tackle the concept of “Vanilla Injection” – refraining from using DI libraries at all.

For further learning, we recommend resources like Fred’s insightful article on transitioning from Dagger/Hilt to Kotlin-Inject, a Dagger issue discussing KSP support, and a Kotlin-Inject discussion on Anvil-like features. Links to these resources, among others, are provided below. Don’t miss out on this engaging and informative episode with Fred Porciúncula!

In this episode, Donn and Kaushik talk to an old friend of the show, Colin White, about Treehouse, a combination of the Redwood and Zipline libraries.

Colin is a Staff Engineer at Cash App (Block).

Redwood is a multiplatform Compose library that allows you to target multiple UI toolkits on various native platforms. Ultimately this allows you to share presentation logic.

Zipline is a multiplatform JavaScript engine for Android, iOS, and the JVM, which uses Kotlin for calls in/out of the JavaScript land. This allows you to update the application logic of your apps without the traditional song and dance of the app store approval and release process.

Treehouse is the combination of both libraries, Redwood and Zipline. Listen in to learn more …

In this episode, Donn and Kaushik talk about one of the age old bike shedding topics – code formatting, and how you can solve it with automation and tools.

Code formatting can turn into an endless debate amongst peers and teams, and what Kaushik and Donn have found is that this can be delegated to a tool and automated. Freeing you and your team of having to worry about proper indentation, bracket placement, etc. By relying on a well defined tool and some automation you can clean your code up, make it much more uniform and easier maintain.

We talk about ktfmt, a Kotlin code formatter that was released by Facebook. We dive into ktlint, detekt and more. We also dive into spotless which can help you by integrating ktfmt into your gradle build pipeline.

In this episode, Donn and Kaushik talk about the fear of shipping, some impostor syndrome and how it contributes to uncertainty and doubt in your capabilities as a software developer.

Recently Donn embarked on a mission to come up with an idea and ship it within 24 hours (which he did do). The end result was a net benefit of confidence, speed and skill acquisition. This helped reduce any doubt, uncertainty and ultimately fear of shipping a product faster.

That’s what this conversation is about … how to doing a project like the 24 hour MVP can remove fear, uncertainty and doubt and help you ship your side project/products faster.

In this short episode, Donn talks about the CODEOWNERS file and how it can help you ensure teams review the code that they are responsible for before merging.

The CODEOWNERS file is a file that you drop into the root of your project (or into the /docs or .github/ directory) that tells GitHub (or whatever git host you’re using) to require a review for any code changes that match the patterns as defined in the CODEOWNERS file. You’ll specify a matching pattern and users, or teams that own that pattern of files and they will be required to review the PR before it can be merged. This helps prevent unwanted changes to files that may or may not be owned by one team or another. This is useful as teams grow larger and need more control over the changes in their application codebase.
