    deep-clean

    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.

    gradle-maven-publish-plugin

    gradle-maven-publish-plugin

    A Gradle plugin that publishes your Android and Kotlin libraries

    A Gradle plugin that publishes your Android and Kotlin libraries, including sources and javadoc, to Maven Central or any other Nexus instance. Gradle plugin that creates a publish task to automatically upload all of your Java, Kotlin or Android libraries to any Maven instance. This plugin is based on Chris Banes initial implementation and has been enhanced to add Kotlin support and keep up with the latest changes. No need to know how publishing works for different project types. AGP provides an API to configure publishing, java-library too, Kotlin Multiplatform does most things automatically but not everything. This plugin configures as much as possible on its own. An unified approach for all kinds of projects. Some parts require manual configuration and for those we provide an API that works regardless of whether this is a Gradle plugin, an Android library or a Kotlin Multiplatform project. This is especially useful for projects that combine multiple of these.

    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.

    kotlin-logging

    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.
