Riverpod
A reactive caching and data-binding framework
Riverpod is a modern, framework-agnostic state management and dependency injection library for Dart and Flutter that emphasizes compile-time safety and explicit data flow. Instead of tying state to widget trees, it models state as providers that can be read anywhere, making logic more testable and decoupled from UI. It supports synchronous state, async data (futures/streams) with built-in loading/error handling, and advanced patterns like derived state and provider scopes. Riverpod’s design reduces rebuilds by letting widgets depend on fine-grained slices of state, which leads to predictable performance in complex apps. The ecosystem includes code generation and utilities that help catch invalid provider usage at compile time rather than at runtime. Overall, it encourages a clear separation of concerns and scales cleanly from small prototypes to large, multi-module applications. -

RxPermissions
Android runtime permissions powered by RxJava2
This library allows the usage of RxJava with the new Android M permission model. If you need to trigger the permission request from a specific event, you need to setup your event as an observable inside an initialization phase. You can use JakeWharton/RxBinding to turn your view to an observable (not included in the library). Because your app may be restarted during the permission request, the request must be done during an initialization phase. This may be Activity.onCreate, or View.onFinishInflate, but not pausing methods like onResume, because you'll potentially create an infinite request loop, as your requesting activity is paused by the framework during the permission request. If not, and if your app is restarted during the permission request (because of a configuration change for instance), the user's answer will never be emitted to the subscriber. -

Sensey
Play with sensor events & detect gestures in a breeze
Sensey is an Android library that simplifies sensor events and gesture recognition. It removes much of the registration, listener, lifecycle, and cleanup boilerplate normally required by Android sensor APIs. Developers enable independent plugins through a concise Kotlin DSL and receive strongly defined gesture events through callbacks. Coroutines and Flow support provide lifecycle-aware streams that pause, resume, and clean themselves up automatically. Jetpack Compose applications can collect the same events through a dedicated effect API. The library recognizes gestures involving shaking, flipping, movement, proximity, orientation, tapping, swiping, sound, steps, rotation, and other device interactions. Its documentation and sample application demonstrate configuration, parameters, and multiple simultaneous gesture plugins. -

Shot
Screenshot testing library for Android
Shot is an Android screenshot-testing framework built as a Gradle plugin and core Android library. It lets developers record reference screenshots and compare them against later test runs to detect visual regressions. Tests use a ScreenshotTest interface and a ready-to-use instrumentation runner integrated with the Android testing workflow. The framework supports traditional Android Views as well as Jetpack Compose components. Gradle tasks handle recording, verification, downloading screenshots, cleanup, and flavor-specific test configurations. When comparisons fail, Shot generates reports that help developers inspect visual differences. It is designed for local development and continuous integration, with emulator configuration guidance for more stable rendering across environments. -

Stepper-Touch
Stepper Touch for Android based on MaterialUp submission
Stepper Touch for Android is based on a Material Up showcase designed by Oleg Frolov. In the latest version of the support library (25.3.0) a new class SpringAnimation was made available. I wanted to test this out and not long after that I found Stepper Touch, a concept made in FramerJS, on Material Up. I took this opportunity to play with SpringAnimations. -

StickyListHeaders
An android library for section headers that stick to the top
StickyListHeaders is an Android library that makes it easy to integrate section headers in your ListView. These section headers stick to the top like in the new People app of Android 4.0 Ice Cream Sandwich. This behavior is also found in lists with sections on iOS devices. This library can also be used without the sticky functionality if you just want section headers. StickyListHeaders actively supports android versions 2.3 (gingerbread) and above. That said, it works all the way down to 2.1 but is not actively tested or working perfectly. The goal of this project is to deliver a high performance replacement to ListView. You should with minimal effort and time be able to add section headers to a list. This should be done via a simple to use API without any special features. This library will always priorities general use cases over special ones. This means that the library will add very few public methods to the standard ListView and will not try to work for every use case. -

Volley
HTTP library that makes networking for Android apps
Volley is an Android networking library that streamlines making asynchronous HTTP requests, caching responses, and managing image loading with minimal code. It provides request queues, thread pools, and lifecycle-aware cancellation so network work integrates cleanly with activities and fragments. Out of the box it supports JSON, string, and image requests, plus an extensible Request/Response model for custom payloads. Volley emphasizes responsiveness: transparent caching and de-duplication of in-flight requests help reduce latency and bandwidth usage. Error handling, retries with backoff, and request prioritization are first-class, making it easier to handle flaky mobile networks. While Android has other HTTP stacks, Volley’s value is in opinionated, high-level primitives that fit common app patterns without pulling in heavy dependencies. -

YCWebView
Based on the Tencent x5 open source library
YCWebView is an Android WebView framework built around Tencent's X5 engine to reduce the amount of custom integration code required for hybrid applications. It provides a decoupled JavaScript bridge for communication between web content and native Android code. Developers can monitor loading progress, network failures, HTTP errors, SSL problems, and other page states through exposed listeners. The framework supports full-screen video, office-document viewing, file uploads, night mode, incognito mode, and display adjustments for notched screens. Resource interception can be combined with OkHttp caching, while optional HTTP DNS handling targets faster and more reliable loading. URL scheme handling covers actions such as calls, messages, email, payments, native-app launching, and other deep-link behaviors. -

Implement tests using nested Given, When, Then
Tests written with commented GIVEN, WHEN and THEN regions can be transformed by actually wrapping code within basic blocks called issues. This can occur in a nested fashion. Start with Test|TEST, that can wrap any issue. Given|GIVEN can wrap Given|GIVEN, When|WHEN; or Then|THEN issues. When|WHEN can wrap When|WHEN or Then|THEN issues. Then|THEN can only wrap Then|THEN issues. The Kotlin implementation supports 'suspend' functions: for any issue, there are two ("suspendable" and "nonsuspendable") kinds, that can be toggled between, while in the same foremost issue. Each issue can be labelled, and return values from corresponding code blocks can be referred to (or addressed, by nesting level), and searched using labels; wildcard matching is available too. Unlabelled given/then/when are not searchable, their return values are stored as the foremost issue's pending result. Supporting coroutines for unit or instrumented tests in Android is under development.
