    Anko

    Anko

    An Android application development library

    Anko is a Kotlin library which makes Android application development faster and easier. It makes your code clean and easy to read, and lets you forget about rough edges of the Android SDK for Java. Anko was born as a type-safe DSL for building Android layouts. It not only allowed creating layouts in a type-safe way, but it made the layouts more adaptable, dynamic, reusable, and also performant, as there was no need for expensive layout inflation. 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.

    Circuit

    Circuit

    A Compose-driven architecture for Kotlin and Android applications

    Circuit is used in production at Slack and is ready for general use. The API is considered unstable as we continue to iterate on it. Circuit is a simple, lightweight, and extensible framework for building Kotlin applications that’s Compose from the ground up. It builds upon core principles we already know like Presenters and UDF, and adds native support in its framework for all the other requirements we set out for above. It’s heavily influenced by Cash App’s Broadway architecture (talked about at Droidcon NYC, also very derived from our conversations with them).

    DivKit

    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.

    FlexboxLayout

    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.

    A Jetpack combined with the MVVM rapid development framework, based on the MVVM model to integrate the JetPack component library officially recommended by Google: LiveData, ViewModel, Lifecycle, and Navigation components use Kotlin language, add a lot of extension functions, simplify the code and add Retrofit network requests, coroutines, to help you Simplify various operations, allowing you to quickly develop projects. 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.

    Kakao

    Nice and simple DSL for Espresso in Kotlin

    At Agoda, we have more than 1000 automated tests to ensure our application's quality and give our best experience to the user. All of them are written with Espresso from Google. Even though Espresso is working really well with our test, the code readability is quite low. Let's look at some of the examples of how we write the test. As Agoda developers, we want to improve not just our codebase quality, but also our implementation of tests as well. This is why we are introducing Kakao. The library will make you enjoy writing automated tests like you are drinking hot chocolate. Nice and simple DSL for Espresso in Kotlin. If you have custom Views in your tests and you want to create your own KView, we have KBaseView. Just extend this class and implement as many additional Action/Assertion interfaces as you want. You also need to override the constructors that you need.

    When Gradle or the IDE let you down, just --nuke all them caches

    A Kotlin script that nukes all build caches from Gradle/Android projects. Useful when Gradle or the IDE let you down. The script has been tested on macOS, but it is completely untested on Linux and Windows. KScript may not work at all on Windows! For this script to work, you need to have kotlin, script, and maven on your PATH. If you don't have all three commands on your PATH, then read on to the next section to install them. To make the script run, we'll first need to install all the required dependencies. All dependencies are available on SDKMan! (Windows, Linux, macOS). Note that KScript support for Windows is not officially available yet.

    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.
