In this episode, we dive into the programming paradigm — Data Oriented Programming (DOP) and why making data the star can simplify your code. Learn how well-modeled data reduces defensive logic, prevents invalid states, and keeps your apps stable. We’ll also contrast DOP with Object Oriented Programming (OOP) and Functional Programming (FP), sharing practical examples, tips, and resource links to deepen your understanding.The full shownotes with illustrations are on fragmentedpodcast.com.Show Notes[announcement] Fragmented has an email newsletter.Programming ParadigmsObject Oriented ProgrammingFunctional ProgrammingData Oriented Programming (DOP)UUIDRFC 4122Kotlin now includes UUID in the standard lib even for kotlin multiplatform.ResourcesBrian Goetz's seminal article on DOPTies Van de Ven Advanced Kotlin Dev Day in 2022Data Oriented Programming in Java by Chris Kiehl (by Manning Publications)Devoxx talk by Nicolai Parlog on youtubeContact usfragmentedpodcast.comContact usYoutubeKaushik:kau.sh (links to ever

In this episode, Kaushik explores the evolution of dependency injection (DI) in Android development. Dagger has been the de-facto solution for DI in Android but there might be a new king in DI-town. He also chats with friend of the show and dependency injection expert Ralf Wondratschek for a final gut check.Shownotes: https://fragmentedpodcast.com/episodes/251

In this episode of our podcast, we explore the diverse landscape of Java versions within the Android ecosystem. Our guest is Michael Bailey, a seasoned Java expert who has been a frequent presence on our show since the early days of our podcast. We kick off with a solid foundation, discussing the differences between JDK and JRE, as well as the distinctions between the available Java JDKs. We also guide listeners through Android Studio settings, exploring how to select a suitable JDK, its utilization, and how it relates to JAVA_VERSION on one's home path/terminal.As we dig deeper, we start to unpack some of the crucial Android app settings. From compileOptions to sourceCompatibility/targetCompatibility, we shed light on why these versions are important. We also demystify the compileSdk vs minSdk vs targetSdk, and how they interconnect. Drawing from Kaushiks's recent experience in building a new app, we provide real-life examples that can better clarify these topics for our listeners.We conclude the episode by

In this edition of Fragmented, we're thrilled to host Ishan Khanna, a software engineer at Tinder who possesses great enthusiasm for feature flags and A/B testing. Donn discusses why he invited Ishan on the show, highlighting Ishan's passion for feature flagging and A/B testing. The conversation kicks off with an insightful story from Ishan about feature flagging at Booking.com, leading to a discussion on the difference between A/B Testing and Feature Flags, when and why to introduce feature flagging, and how to measure its effectiveness. The show also focuses on the benefits and risks of feature flagging, along with ways to manage potential complexities in the codebase.We then delve deeper into the topic of feature flagging, covering how to get started, what to look for in a tool, and the role of testing. Discussion points include the best practices for rollout percentages, considerations for multi-platform implementation, and the specifics of targeting in feature flagging. The conversation wraps up with an

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 modulariz

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 timeles

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.

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.Linksktfmt - website, githubspotless - githubdetekt - websitektlint - websiteDonn's Git CourseNeed to learn Git?

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.LinksDonn's 24 Hour Project - EXIFRJumpstart Rails Template that Donn UsedBooks-AI App by Florian WaltherOpen AIDonn's Git CourseNeed to learn Git?

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.LinksCODEOWNERS GitHub DocEpisode 012 - CI and Collective Code OwnershipGitHub Organization TeamsDonn's Git CourseNeed to learn Git?
