Built to incorporate with existing Android applications and also Jetpack collections, you can embrace Compose at your very own speed by integrating Android Views and also Compose.

With this beta launch, Compose is API full and also has all the functions you require to develop production-ready applications. Beta additionally implies API secure, so we won’t transform or get rid of APIs. Now is a fun time to begin finding out Compose and also start preparing for just how you will certainly utilize it in a future job or attribute once it gets to 1.0 later on this year.

What’s In Beta

Since open sourcing advancement in 2019, we’ve had 30 public launches, resolved over 700 outside insects, and also approved over 200 outside payments. We enjoy seeing what you’ve been developing with Compose and also have actually utilized your responses and also attribute demands to improve our APIs and also prioritize our job. Since the alpha launch, we’ve included and also enhanced a variety of brand-new functions:

  • 🆕 Coroutines assistance
  • 🆕 Accessibility assistance for Talkback – assistance for various other modern technologies will certainly remain in Stable
  • 🆕 Easy to make use of Animations, with a totally brand-new API considering that alpha.
  • Interoperability with Views
  • Material UI Components, all with @Sampled code
  • Lazy Lists – Jetpack Compose’s tackle RecyclerView
  • DSL-based Constraint Layout
  • Modifiers
  • Testing
  • Theming and also Graphics, with simple assistance for Dark and also Light setting
  • Input and also motions
  • Text and also editable message
  • Window monitoring

For the beta launch, we’ve been concentrated on making certain API efficiency; that all fundamental APIs remain in area for us to remain to build on for 1.0 and also past. We’ll deal with maintaining these APIs approximately our 1.0 launch with specific concentrate on application efficiency and also availability.

Works with your existing application

Jetpack Compose is developed to function perfectly with Android Views, allowing you embrace at your very own speed. You can install Compose UIs within Android Views and also usage Views within Compose. We outlined a variety of fostering techniques in our interoperability paperwork.

In enhancement to View interop, we incorporate with usual collections to assist you to include Compose to your existing applications—no requirement to revise or re-architect your application. We supply combinations with:

Thinking in Compose

Jetpack Compose is a declarative UI toolkit, a standard change from the present View system, where you define what your UI ought to resemble for an offered application state, not just how to create it. Compose deals with upgrading your UI when your application state modifications, so you don’t need to adjust your UI right into the preferred state which can be tiresome and also mistake vulnerable.

Built totally in Kotlin, Compose capitalizes on its wonderful language functions to supply effective, concise, instinctive APIs. Coroutines as an example allow us to create much easier async APIs such as defining motions, computer animation or scrolling. This makes it less complicated to create code that integrates async occasions, like a motion which hands off to a computer animation, all with termination and also clean-up supplied by organized concurrency.
