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 Drag Dismiss Activity
A smooth, easy-to-implement, drag to dismiss Android Activity
Another implementation of the drag-to-dismiss Activity pattern. This one is inspired by Nick Butcher's Plaid implementation. The project has a simple API and is a pretty powerful and beautiful implementation of the pattern. This library is used in some of my apps (Talon for Twitter and Pulse SMS). It has been abstracted from Jacob Klinker and I's article-android library, which is an awesome readability style in-app web browser. This library provides an elastic layout that can dismiss an Activity with a RecyclerView or a regular Activity. Whenever the user swipes up or down, from the bottom or the top of the content, the DragDismissActivity will finish. -

Android Easy MultiDex
Android, multidex, splitdex, subpackage plugin
Android, multidex, splitdex, subpackage plugin. The Gradle script was integrated into the plug-in, so that only one configuration file needs to be maintained. Readers can choose separate configuration or integrated configuration according to their own needs. In this way, we maintain the number of methods of the main Dex at about 15,000, and we no longer have to worry about the number of methods. Through the above official subcontracting, the original Dex has been divided into 1 master Dex and more slave Dex. The main Dex contains all 4 major components, Application, Annotation, multidex, etc. and their necessary direct dependencies. Since the number of our methods has reached 16W, hundreds of activities were all stuffed into the main Dex, and the main Dex was successfully exploded. -

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. -

Android Interview Questions
Your Cheat Sheet For Android Interview
This repository is a comprehensive study guide for Android interviews, organized to cover the platform from fundamentals to advanced topics. It includes explanations and Q&A on the Android app lifecycle, activities and fragments, services, broadcast receivers, content providers, and the build system. Modern practices are addressed as well—Kotlin language features, coroutines, Jetpack components, MVVM/MVI architecture, dependency injection, and testing strategies. Performance and reliability topics receive attention, such as memory management, threading, WorkManager, networking, and offline storage patterns. The content favors concise, practical answers that interviewers expect, helping candidates rehearse concepts and trade-offs rather than memorize trivia. It’s equally useful for brushing up before an interview and for leveling up day-to-day Android engineering knowledge. -

Android Layout Engine
A JSON based LayoutInflater for Android
Proteus is meant to be a drop-in replacement for Android’s LayoutInflater; but unlike the compiled XML layouts bundled in the APK, Proteus inflates layouts at runtime. With Proteus, you can control your Apps layout from the backend (no WebViews). Forget the boilerplate code to findViewById, cast it to a TextView, and then setText(). Proteus has runtime data bindings and formatters. Plugin in your own custom views and attributes and functions to flavour proteus to your requirements. -

Android Persistent Search Library
A clone of the Google Now/Maps/Play persistent search bar
PersistentSearch is an open-source Android UI library that recreates the persistent search bar found in older Google Now, Google Maps, and Google Play interfaces. It allows developers to integrate a familiar search component directly into application layouts. The library provides an expandable search field with customizable branding and interactive search suggestions. Developers can populate suggested results with titles and accompanying icons. Built-in listeners report search queries, text changes, result selections, and search field interactions. It also supports voice recognition through Android's speech recognition interface. Additional methods allow search interfaces to open from toolbar menu items and customize elements such as logo text colors. PersistentSearch can be integrated into Android Studio or Eclipse projects, although development has been formally discontinued. -

Android Sliding Up Panel
A simple way to add a draggable sliding up panel to Android apps
This library provides a simple way to add a draggable sliding up panel (popularized by Google Music and Google Maps) to your Android application. As seen in Umano Android App (now acquired by Dropbox). If you are using the library and you would like to have your app listed, simply let us know. Simply add the following dependency to your build.gradle file to use the latest version. Include com.sothree.slidinguppanel.SlidingUpPanelLayout as the root element in your activity layout. The layout must have gravity set to either top or bottom. Make sure that it has two children. The first child is your main layout. The second child is your layout for the sliding up panel. The main layout should have the width and the height set to match_parent. The sliding layout should have the width set to match_parent and the height set to either match_parent, wrap_content or the max desireable height. -

Android System Bar Tint
Apply background tinting to the Android system UI
Apply background tinting to the Android system UI when using KitKat translucent modes. Android 4.4 (KitKat) introduced translucent system UI styling for status and navigation bars. These styles are great for wallpaper based activities like the home screen launcher, but the minimal background protection provided makes them less useful for other types of activity unless you supply your own backgrounds inside your layout. Determining the size, position and existence of the system UI for a given device configuration can be non-trivial. This library offers a simple way to create a background "tint" for the system bars, be it a color value or Drawable. By default it will give you a semi-opaque black background that will be useful for full-bleed content screens where persistent system UI is still important - like when placed over a map or photo grid. -
