It provides developers with low-level access to gr

A layout engine for Android that decouples layouts from the View containers that manage scrolling and view recycling. FreeFlow makes it really easy to create custom layouts and beautiful transition animations as data and layouts change

AndroidSwipeLayout is an Android UI library and custom view framework that enables the creation of layouts that reveal hidden action buttons when a user performs a swipe gesture. It functions as a gesture-based UI component that triggers callbacks based on the real-time position of the swipe. The framework is designed to support complex interaction patterns, specifically allowing for the nesting of multiple swipeable components within one another. The library covers mobile gesture interaction and custom view orchestration, providing tools to track swipe states and synchronize UI changes duri

An elegant way to show your menu or messages.

Booster is an Android app build optimizer and bytecode manipulator designed to reduce binary size, fix system-level crashes, and improve application performance. It functions as an extensible build process plugin that modifies compiled class files and build artifacts to inject stability fixes and optimizations without altering the original source code. The project differentiates itself through low-level bytecode manipulation to patch OS-level bugs and manage thread pools during the compilation phase. It also provides a performance profiling toolkit to identify main-thread blocking operations

DoraemonKit is a mobile frontend development toolset designed to optimize the lifecycle of web and hybrid mobile applications. It functions as a comprehensive suite of productivity tools, providing specialized utilities for mobile UI inspection, web view debugging, and on-device performance monitoring. The toolset distinguishes itself through several targeted simulation and interception capabilities. It includes a network traffic interceptor for mocking API responses without modifying source code, a device state simulator for overriding GPS coordinates, and a mobile web debugging bridge that

VirtualAPK is an Android plugin framework and runtime environment designed to load and execute external Android packages dynamically. It functions as a component host that allows a main application to run activities, services, and providers delivered via external modules without requiring system installation or manifest registration. The framework enables dynamic feature delivery by loading external packages at runtime, allowing application functionality to be updated without redeploying the entire app. It provides a mechanism for Android sandbox execution, running isolated components within

Andromeda simplifies local/remote communication for Android modularization

SwipeBackLayout is an Android gesture navigation library and view component designed to implement edge-swipe gestures for navigating back to previous screens. It provides the underlying logic and layout management necessary to integrate horizontal swipe transitions into an application's screen stack. The library utilizes a custom layout manager to coordinate the simultaneous movement of foreground and background views. It maps horizontal touch offsets to the translation and opacity of view hierarchies, using interpolation to calculate visual progression based on the swipe percentage. The sys

android-crop is an Android image cropping library and image picker. It provides a reusable view component for selecting and cropping rectangular areas of images within mobile applications. The project includes an interface for launching the system gallery to select photos and a visual tool for users to manually adjust image framing. It manages the process of extracting specific regions of a bitmap and discarding the surrounding pixels.

This is an Android pull-to-refresh library and custom view component designed to implement refresh interactions across any Android view. It functions as a gesture interaction tool that manages pull-down motions and touch conflicts to trigger data loading operations. The library provides tools for creating custom refresh headers and indicator visuals, utilizing a path-based animation engine to produce non-linear visual transitions. It includes mechanisms to define specific trigger thresholds through height ratios and user release events. The project covers gesture management and touch interac

Robust is an Android hotfix framework and runtime application updater designed for patching bugs in production environments. It functions as a bytecode patcher and dynamic code injection tool, allowing for the modification of application logic without requiring a full app update or device reboot. The project enables the remediation of Android defects by injecting new classes and methods into existing builds and modifying the implementations of existing methods. It utilizes a toolchain to generate binary patch files that update application behavior and introduce workarounds on the fly. The sy

Walle is a tooling system for automating the injection of distribution channel identifiers and metadata into signed Android application binaries. It functions as a command-line utility and build pipeline extension that reads and writes custom metadata directly into the Android application signing block. The tool specifically modifies the Android Signature V2 block to embed channel identifiers and key-value pairs without re-signing the binary. This approach enables the generation of multiple channel-specific application packages without requiring a full binary rebuild or repeated signing opera
