ActionBar-PullToRefresh
Add a modern version of the pull-to-refresh interaction to your app
ActionBar-PullToRefresh is a lightweight Android library that provides a modern implementation of the pull-to-refresh interaction inspired by the behavior seen in applications like Gmail. Unlike its predecessor, it was designed as a cleaner and more streamlined approach, focusing on simplicity and better integration with the Android Action Bar. The library introduces a visually distinct refresh mechanism where a progress indicator emerges from the Action Bar area, creating a more polished and contemporary user experience. It supports multiple view types such as ListView, GridView, ScrollView, and WebView, while also allowing developers to extend functionality through custom delegates. One of its key features is automatic styling based on the application’s Action Bar theme, reducing the need for manual customization. The API is designed to be flexible, enabling developers to control refresh behavior, animations, and text feedback. -

Aesthetic
Android theming library
Aesthetic is an Android theming library designed to help apps apply dynamic visual styling at runtime. It allows developers to configure colors and theme properties programmatically instead of relying only on static XML resources. The library can apply app-wide defaults and includes a first-time configuration check so developers can initialize theme settings on launch. It was built for apps that need user-selectable themes, color customization, or consistent styling across screens. Aesthetic also includes sample usage patterns and configuration APIs to help Android projects manage appearance changes more cleanly. The project is no longer actively modern, but it remains a useful reference for runtime theming approaches in Android apps. -

Amazon Chime SDK for Android
An Android client library for integrating multi-party communications
The Amazon Chime SDK for Android makes it easy to add collaborative audio calling, video calling, and screen share viewing features to Android applications by using the same infrastructure services that power meetings on the Amazon Chime service. This Amazon Chime SDK for Android works by connecting to meeting session resources that you have created in your AWS account. The SDK has everything you need to build custom calling and collaboration experiences in your Android application, including methods to: configure meeting sessions, list and select audio devices, switch video devices, start and stop screen share viewing, and receive callbacks when media events occur such as volume changes, and manage meeting features such as audio mute and video tile bindings. We also have an Amazon Chime SDK Project Board where you can find community requests and their statuses. -

AndServer
Web server and web framework of Android platform
AndServer is an embedded HTTP server, web framework, and reverse proxy designed for Android applications. It can host static HTML sites directly from a device or expose dynamic HTTP APIs. Its annotation model resembles Spring MVC, including controllers, route mappings, path variables, query values, and request parameters. Developers can configure ports, timeouts, listening addresses, socket factories, and SSL contexts through a builder API. Request objects expose local and remote connection details for application logic and diagnostics. A separate proxy mode maps incoming hosts or addresses to upstream HTTP and HTTPS destinations. The proxy component performs forwarding but does not provide load balancing. -

Android Auto Scroll ViewPager
Android common lib, include ImageCache, HttpCache, DropDownListView
Android Auto Scroll ViewPager is a Java-based UI library for Android applications that enhances the standard ViewPager component by adding automatic scrolling and cycling behavior, making it particularly useful for image carousels, featured content sliders, and other rotating views. Designed to extend the classic Android support library’s ViewPager, it enables views to scroll automatically at a configurable interval while also allowing manual swiping by the user, combining both automation and interactive control. In addition to auto-scroll timing, developers can configure the scroll direction, cycle mode (so the pager loops continuously), and animation duration to create smooth and responsive carousel experiences. The library also includes settings to control whether scrolling stops when the user touches the component and how border conditions are handled at the start or end of the list. -

Android Hidden APIs
A library that provides access to Android hidden APIs
Android Hidden APIs are classes, methods, and resources that Google hides from you because of stability reasons. These features are hidden because they may be changed on next API version. The internal APIs are located in package com.android.internal and available in the framework.jar, while the hidden APIs are located in the android.jar file with @hide javadoc attribute. Now you know the difference. But I will refer to both as hidden APIs. This repo contains a custom android.jar which you can use to develop your app. -

Android Image Slider
An amazing and convenient Android image slider
The Android Image Slider project is an Android UI component/library that provides a convenient, customizable image slider (carousel) for mobile apps. Instead of building a custom slider from scratch, developers can drop in this library’s slider view into their layout and configure it via XML or code to display a series of images — from local drawables, files, or remote URLs — with smooth transitions, animations, and optional indicators. This significantly simplifies development of galleries, onboarding screens, advertisement banners, or any UI requiring swipable images in Android apps. The library supports various slide animations (transitions), auto-sliding, and event listeners (e.g., click events on slides), giving developers flexibility around how the slider behaves. For mobile apps where image-heavy UI is common (e.g. e-commerce, portfolios, media galleries), AndroidImageSlider offers a ready-made, tested component that saves time and ensures consistency. -
