Overview Dependency injection is a programming pattern which prescribes that classes do not construct instances of their dependencies, instead such instances are provided. This pattern enables separation of concerns, and increases testability, reusability, and ease of maintenance. See Dependency injection in Android to review the benefits of dependency injection and its core concepts. You may already be familiar with Hilt, the Android library based on Dagger which implements a dependency injection solution for Android apps. Hilt’s approach includes two important features: Providing dependenci ..read more

Strong skipping mode is an experimental feature in the Jetpack Compose Compiler 1.5.4+ that is currently being tested. It is part of our work to make the code you naturally write more performant. We don’t want you to have to be experts in Compose internals in order to write good Compose code! Strong skipping mode changes the rules for what composables can skip recomposition and should greatly reduce recomposition by allowing composables with unstable parameters to be skipped, and additionally, automatically remembering lambdas with unstable captures. This change may seem small, but the behavi ..read more

We’ve just released new documentation covering how to use the graphics-shapes library in Jetpack Compose. Whilst that covers the basics, I thought it would be fun to try something a bit more advanced and create a different looking progress bar than the standard ones we are used to. In this blog post, we will cover how to create this progress bar that transitions from a squiggly “star” shaped rounded polygon to a circle while performing the regular progress animation. Squiggly line gradient infinite progress barCreate the polygons The first step we want to perform is a transitio ..read more

Lists are at the core of most Android apps. Over the years, different solutions were introduced to ensure other UI components could interact with such lists — for instance, how an app bar reacts to list scrolls or how nested lists interact with one another. Have you ever encountered a situation where you have one list inside another and, by scrolling the inner list to the end, you’d like the outer list to continue the movement? That’s a classic nested scrolling example! Nested scrolling is a system where scrolling components contained within each other can communicate their scrolling deltas t ..read more
