Workflow
A Swift and Kotlin library for making composable state machines
Workflow is an application framework that provides architectural primitives. A corresponding testing framework that facilitates simple-to-write unit tests for all application business logic and helps ensure correctness. Corresponding UI frameworks that bind Rendering data classes for “views” (including event callbacks) to Mobile UI frameworks for Android and iOS. Optimized for composability and scalability of features and screens. A library that supports writing business logic and complex UI navigation logic as state machines, thereby enabling confident reasoning about the state and validation of correctness. A unidirectional data flow library that uses immutable data within each Workflow. Data flows in a single direction from the source to the UI, and events in a single direction from the UI to the business logic. Each logical component area is separated into a Workflow with a finite set of states and the logic to transition between them. -

DivKit
DivKit is an open source Server-Driven UI (SDUI) framework
DivKit is an open source Server-Driven UI (SDUI) framework. It allows you to roll out server-sourced updates to different app versions. Also, it can be used for fast UI prototyping, allowing you to write a layout once and then ship it to iOS, Android, and Web platforms. DivKit is an excellent choice to start using server-driven UI in your project because it can be easily integrated as a simple view in any part of your app. At the starting point, you don’t need a server integration. You can include all JSON on the client-side to try it in a real-world application. Also, we’ve made a sandbox for you to experiment with. You can try different samples in the web editor and see the results on the web or in the Android demo app, both of which are available on Google Play. We’ll publish the iOS demo app shortly. The UI in the demo can be updated live: the sandbox connects to the demo app via web sockets. -

kotlin-logging
Lightweight Multiplatform logging framework for Kotlin
Lightweight Multiplatform logging framework for Kotlin, written in Pure Kotlin. A convenient and performant logging facade. Version 5 is not backward compatible with previous versions (v.3, v.2, v.1). Group id (in maven) and package names changed. It is possible to use both version 5 and previous versions side-by-side so some of the code from the old version and some new. It is also possible to have libs using old version and use the new version (and vice-versa). After seeing many questions like the Idiomatic way of logging in Kotlin and Best practices for loggers, it seems like there should be a standard for logging and obtaining a logger in Kotlin. -

Anko consists of several parts that make up the complete framework, which are: Anko Commons: a lightweight library full of helpers for intents, dialogs, logging and so on. Anko Layouts: a fast and type-safe way to write dynamic Android layouts. Anko SQLite: a query DSL and parser collection for Android SQLite. Anko Coroutines: utilities based on the kotlinx.coroutines library. -

FlexboxLayout
Flexbox for Android
FlexboxLayout is a library project which brings the similar capabilities of CSS Flexible Box Layout Module to Android. Starting from 1.1.0, the library is expected to use with AndroidX. You should migrate to AndroidX if you use 1.1.0 or above. There are two ways of using Flexbox in your layout. The first one is FlexboxLayout that extends the ViewGroup like LinearLayout and RelativeLayout. You can specify the attributes from a layout XML. The second one is FlexboxLayoutManager that can be used within RecyclerView. The advantage of using FlexboxLayoutManager is that it recycles the views that go off the screen for reuse for the views that are appearing as the user scrolls instead of inflating every individual view, which consumes much less memory especially when the number of items contained in the Flexbox container is large. -

The sample format is the data format returned by the Android Api. If the errorCode is equal to 0, the request is successful, otherwise the request fails. From the developer's point of view, we mainly want to get the unpacking data-data, and we don't want to judge errorCode==0 every time. Whether the request is successful or failed At this time, we can inherit BaseResponse in the server return database class and implement related methods. -
