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. -

RxJavaSamples
Examples of some of the most common usages of RxJava 2 and Retrofit
Examples of some of the most common uses of RxJava 2 with Retrofit. For the interface that needs to request the token first, then use flatMap() to connect the token request and the actual data request coherently, without having to write a nested Callback structure. For non-disposable tokens (tokens that can be reused), after obtaining the token, save it for repeated use, and use retryWhen() to automatically re-acquire the token when it expires, making the process of token acquisition completely transparent and simplified. Convert the returned data into a more convenient format and give it to the Observer. -

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. -

Snap.js
A Library for creating beautiful mobile shelfs in Javascript
A Library for creating beautiful mobile shelfs in Javascript. As standalone just include the file in a script tag. The slide intent is an int between 0 and 90, and represents the degrees in the first quadrant of a circle that you would like to have mirrored on the X and Y axis. For example, if you have 40 set as your slideIntent value, the user would only be able to slide the pane by dragging in the blue area in the diagram below. Once intent has been defined, it will not change until the user releases. CSS3 Powered Animations with IE fallbacks, drag support, drag handle support. Programatic API, "No-Drag" elements, and definable easing mode. Enable/disable events, disabled sides (left or right). It supports Ratchet (with templates!). Because of the nature of this code, drawers are just kind of stacked behind the content. To bring the proper drawer to the front, you can hook into Snaps.js' CSS classes. -

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. -

Store5
A Kotlin Multiplatform library for building network-resilient apps
Modern software needs data representations to be fluid and always available. Users expect their UI experience to never be compromised (blocked) by new data loads. Whether an application is social, news or business-to-business, users expect a seamless experience both online and offline. International users expect minimal data downloads as many megabytes of downloaded data can quickly result in astronomical phone bills. Store is a typed repository that returns a flow of Data /Loading /Error from local and network data sources. -

Subsampling Scale Image View
Deep zoom view for displaying huge images without loss of detail
Android library (AAR). Highly configurable, easily extendable deep zoom view for displaying huge images without loss of detail. Perfect for photo galleries, maps, building plans etc. A custom image view for Android, designed for photo galleries and displaying huge images (e.g. maps and building plans) without OutOfMemoryErrors. Includes pinch to zoom, panning, rotation and animation support, and allows easy extension so you can add your own overlays and touch event detection. The view optionally uses subsampling and tiles to support very large images - a low resolution base layer is loaded and as you zoom in, it is overlaid with smaller high resolution tiles for the visible area. This avoids holding too much data in memory. It's ideal for displaying large images while allowing you to zoom in to the high resolution details. You can disable tiling for smaller images and when displaying a bitmap object. -

SurvivalManual
Libre Survival Manual for Android with offline in mind
This is a survival manual/guide based on the public domain US Army Survival Field Manual FM 3-05.70 (FM 21-76). It is fully functional offline, which is important in the case of a catastrophe. But it doesn't have to be used only in emergency situations, it can also be useful for outdoor trips, walks, camps, and learning about nature and yourself truly. This is not only fun, but you can also train skills (fire, build shelter, ...) that you may need in a catastrophe. Some things work best with practice in a relaxed environment, so you also have time for some experiments. The refugees also are welcome to use this application to prepare and guide you for your dangerous journey. Although I hope that we as humans will come to feel and stop wars and end climate injustice so that people do not have to flee and be afraid. -

Transitions Everywhere
Set of extra transitions on top of Jetpack transitions library
Originally this library was a full backport of Android Platform's Transitions API. Then all the bug fixes from the library were ported into AndroidX Transitions (previously Support library). Now this lib has minSdk version 14 (Android 4.0 ICS) and consists of some transitions which are not a part of the official set. Internal Transitions that was marked as @hide in the platform are recolor, rotate, change text and crossfade. As well as two extra transitions, which are scale and translation. Migrate to AndroidX! Support libraries are not updating anymore, to get all the bug fixes you have to use AndroidX transitions. Replace imports for all the classes which are a part of the AndroidX lib. Some setters in AndroidX transitions are not following the builder pattern, please rewrite this usages with introducing a helper variable if you encounter the issue. -

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. -

Zepto.js
JavaScript library for modern browsers with a jQuery compatible API
Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto. While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. The goal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatile API, so you can concentrate on getting stuff done. Zepto is open source software and is released under the developer and business-friendly MIT license. Note that some optional features of Zepto specifically target mobile browsers; as the original project goal was to specifically provide a leaner alternative to jQuery for the mobile web. Zepto is a good choice for browser extensions (for Safari, Chrome and Firefox) and to develop HTML-based views within native app frameworks, such as PhoneGap. In short, Zepto is expected to work in every modern browser and browser-like environment.
