It recommends mapping the compiler and build toolchain, upgrading from a known compatibility matrix, cleaning and inspecting generated output, verifying dependency graphs across flavors and targets, testing runtime slices, and keeping rollback changes coherent. ### Source excerpt A K2 migration is usually planned around source compatibility and compiler diagnostics. Projects that generate or validate dependency wiring need another checklist: compiler plugin versions, generated sources, metadata compatibility, and graph verification on every target. Map the toolchain first Record the Kotlin plugin, Compose compiler plugin, KSP or annotation tooling, dependency-injection compiler plugin, Android Gradle plugin, and target libraries. Upgrade from a known matrix instead of selecting each latest version independently. ## Use compile-time DI checks without losing runtime tests DevFeed: [Use compile-time DI checks without losing runtime tests]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: tutorial Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [test](), [configuration]() Tags: [compiler](), [configuration](), [dependency](), [lifecycle](), [tests](), [validation]() ### AI overview The article explains how compile-time dependency injection validation can catch structural problems such as missing definitions, invalid qualifiers, and broken constructor paths before application startup. It emphasizes that runtime tests remain necessary for configuration, parameters, lifecycle behavior, and ownership, and recommends using layered validation. ### Source excerpt Compile-time dependency validation can catch a missing definition, an invalid qualifier, or a broken constructor path before an application starts. That is valuable. It does not prove that runtime configuration, parameters, or lifecycle behavior are correct. Divide the evidence Let compiler validation answer structural questions: Can the graph resolve this constructor path? Does a binding exist for the requested type and qualifier? Is generated wiring compatible with the declaration? Let tests answer behavioral questions: ## Build a dependency-graph inventory before changing the container DevFeed: [Build a dependency-graph inventory before changing the container]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: tutorial Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [Dependency injection](), [Android](), [test](), [Gradle]() Tags: [android](), [build](), [configuration](), [dependency](), [graph](), [process](), [test]() ### AI overview This tutorial recommends creating a framework-independent dependency-graph inventory before migrating dependency injection. It explains how to document entry points, ownership, implementations, lifetimes, qualifiers, modules, replacement values for tests, and architectural constraints, then validate the design through smaller executable test slices. ### Source excerpt A dependency-injection migration often starts with framework syntax. That is too late. First describe the graph without using the framework's vocabulary. The inventory should show which objects exist, who owns them, and which runtime fact selects one implementation over another. Start from entry points List application entry points: the Android application, a worker, a navigation destination, a command-line process, and each test fixture. Trace the objects requested at each entry point. Stop the trace at explicit boundaries such as a database driver, HTTP transport, clock, file system, or platform service. ## Keep Kotlin Multiplatform bindings at the platform boundary DevFeed: [Keep Kotlin Multiplatform bindings at the platform boundary]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: tutorial Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [Kotlin Multiplatform](), [Kotlin](), [implementation](), [modules](), [configuration](), [test]() Tags: [configuration](), [implementation](), [kotlin](), [kotlin-multiplatform](), [module](), [multiplatform](), [test](), [verification]() ### AI overview A guide to keeping Kotlin Multiplatform dependency bindings at platform boundaries. It recommends defining small capability interfaces in common code, implementing them in platform source sets, organizing modules around capabilities and product features, and testing both shared contracts and real platform bindings. ### Source excerpt Kotlin Multiplatform makes source-set boundaries visible, but a dependency container can blur them again. A shared module should state a capability such as secure storage, HTTP transport, or local time. The platform source set should supply the implementation. Put contracts where consumers can see them Define the smallest useful interface in common code. Avoid copying a platform API into that interface. A storage contract might expose read, write, and remove; it does not need to expose Android preferences or an Apple keychain type. ## Review a Koin upgrade as a graph change, not a version bump DevFeed: [Review a Koin upgrade as a graph change, not a version bump]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: tutorial Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [Dependency injection](), [upgrade](), [modules](), [test](), [Compose]() Tags: [android](), [compose](), [dependency-injection](), [modules](), [test](), [upgrade]() ### AI overview This tutorial explains how to review a Koin dependency-injection upgrade as an architecture change rather than a simple version bump. It recommends recording the existing dependency graph, modules, warnings, startup results, and verification output; upgrading mechanisms separately; checking all startup variants; and maintaining tested rollback procedures. ### Source excerpt Dependency-injection upgrades can change more than API names. Verification behavior, annotation processing, Compose packages, compiler integration, and deprecations can all alter how the graph is built. Treat the upgrade as an architecture change with a defined before-and-after record. Freeze the current graph Before changing versions, save the dependency lock or resolved graph, the list of DI modules, startup smoke-test results, and verification-test output. Record warnings that already exist so a new warning is not confused with old noise. ## Turn a framework roadmap into an application decision record DevFeed: [Turn a framework roadmap into an application decision record]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: tutorial Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [Framework](), [Maintainers](), [Documentation]() Tags: [framework](), [guide](), [maintainers](), [roadmaps](), [validation]() ### AI overview A practical guide to turning framework roadmap items into application decision records. It recommends classifying roadmap items by availability and stability, evaluating them against concrete problems and current documentation, recording fallbacks and constraints, and setting a review trigger before considering architectural changes. ### Source excerpt Framework roadmaps are useful because they show where maintainers expect the design to move. They are not release guarantees and they do not replace an application's own constraints. Convert roadmap items into explicit questions before changing architecture. Classify each item Place a roadmap item in one of four groups: available and documented; available but experimental; announced but not released; or directional only. Only the first group should normally support a production decision without added risk controls. For experimental work, record the fallback and the boundary that contains it. ## Match Compose injection scopes to real UI ownership DevFeed: [Match Compose injection scopes to real UI ownership]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: tutorial Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [Compose](), [ui](), [navigation](), [Process]() Tags: [compose](), [lifecycle](), [navigation](), [screen](), [ui]() ### AI overview This tutorial explains how to align Compose injection scopes with actual UI ownership and lifecycle events. It distinguishes object retrieval from creation, discusses process, navigation-destination, request, and feature-session lifetimes, and recommends testing both retention and exit behavior. ### Source excerpt Compose makes it easy to request an object close to the UI that uses it. Proximity is useful, but it does not define ownership. Recomposition can call a function many times. Navigation can keep or discard a back-stack entry. The operating system can recreate the process. A sound scope names the event that owns the object. Separate retrieval from creation Ask two questions for each injected object: Where is the object retrieved? Which lifecycle creates and releases it? A repository retrieved by a composable can still be process-scoped. A screen model can be owned by a navigation destination. A transient formatter can be created for each request. Write the lifetime next to the definition and test that the object survives, or does not survive, the intended event. ## Find technical debt at dependency-injection boundaries DevFeed: [Find technical debt at dependency-injection boundaries]() Original publisher: [Read original article]() Published: 2026-08-18T00:00:00Z Content type: article Language: en Sources: [Koin - Cloud-Inject.io -Kotzilla]() Topics: [Dependency injection](), [Framework](), [Code]() Tags: [architecture](), [defects](), [dependency-injection](), [errors](), [review](), [structure](), [technical](), [test](), [tests]() ### AI overview This article explains how dependency-injection code can expose architectural debt. It identifies signals such as oversized modules, string qualifiers, lifetime inversion, construction that starts work, broad production-container tests, and definitions spread across UI locations. It recommends paying down debt at product-slice boundaries, separating construction from behavior, adding focused graph and behavior tests, and measuring ownership, verification, startup, and test setup. ### Source excerpt Dependency-injection code is often treated as plumbing. It is also a compact map of architecture decisions. Review it for debt signals before adding another binding. Signals worth investigating An oversized application module usually means feature boundaries are not explicit. String qualifiers can hide a missing type. Definitions that open databases or start jobs during graph creation mix construction with behavior. A process-scoped object that accepts a screen-owned dependency indicates lifetime inversion.
