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-State
A utility library for Android to save objects in a Bundle
A utility library for Android to save objects in a Bundle without any boilerplate. It uses an annotation processor to wire up all dependencies. It's recommended to turn on a global setting in your Application class to save and restore the instance state of all activities and fragments from the support library. After that you only need to annotate your fields with @State inside of your fragments and activities. You can save any type which can be saved in a Bundle like the String, Serializable, and Parcelable data structures. -

AndroidEventBus
Library for android, simplifies communication between services
AndroidEventBus is an Android-oriented event dispatching library that provides a flexible, lifecycle-aware, and decoupled mechanism for managing communication between components without tight coupling — especially useful in large, modular applications. It allows developers to define and post custom events that can be observed by multiple parts of an app, such as UI controllers, services, or background workers, without requiring direct references between senders and receivers. Unlike simple observer patterns, AndroidEventBus typically integrates with Android lifecycles so that subscribers are automatically registered, paused, or cleaned up based on activity/fragment state — reducing memory leaks and errant behavior during configuration changes. The library aims to simplify common inter-component messaging tasks (like posting a login success event or notifying multiple listeners of state changes) while preserving type safety and performance. -

AndroidOfferKiller
Help you get a better offer
AndroidOfferKiller is a curated collection of Android interview resources aimed at helping developers secure stronger job offers. It brings together notes and materials across topics such as Java and JVM basics, Android fundamentals, design patterns, data structures and algorithms, and LeetCode-style problem solutions. The repository also links to deep-dive articles on performance and common pitfalls, for example RecyclerView stutter and optimization strategies, making it a practical study companion rather than just a list of questions. It includes sections about referral channels and hiring information for certain companies, highlighting real-world hiring context in addition to theory. The project positions itself as an all-in-one preparation hub where you can review core CS topics, Android specifics, and optimization best practices before interviews. It is open-source and licensed under Apache-2.0, allowing learners to contribute new questions, solutions, and articles over time. -

BLESSED for Android
BLESSED, a Bluetooth Low Energy (BLE) library for Android
BLESSED is a very compact Bluetooth Low Energy (BLE) library for Android 5 and higher, that makes working with BLE on Android very easy. It takes care of many aspects of working with BLE you would normally have to take care of yourself. The BLESSED library was inspired by CoreBluetooth on iOS and provides the same level of abstraction, but at the same time it also stays true to Android by keeping most methods the same and allowing you to work with the standard classes for Services, Characteristics and Descriptors. If you already have developed using CoreBluetooth you can very easily port your code to Android using this library. -

BasePopup
Create a universal and convenient PopupWindow popup library
BasePopup is a popup library that encapsulates and improves the system PopupWindow. It is a basic library class with a very high degree of freedom and rich API. You can easily complete various popups under the framework of BasePopup. Switching between Release and Snapshot versions may cause Build to fail. At this time, you can clean the Project. QuickPopup adds new APIs and modifies the implementation of QuickPopupConfig to make the code cleaner and cleaner. In response to historical issues, we have unified the role of the root layout margin under match_parent and wrap_content this time. Now the role is consistent with the system and used as margin instead of offset. -

Blurhash
Library to show colorful blurry placeholders while your content loads
A library to show colorful blurry placeholders while your content loads. Does your designer cry every time you load their beautifully designed screen, and it is full of empty boxes because all the images have not loaded yet? Does your database engineer cry when you want to solve this by trying to cram little thumbnail images into your data to show as placeholders? Replace boring grey boxes with beautiful blurhash states and the designers will be happy. Blurhash strings are short enough to be added as a field in a JSON object and to be stored in a database. The implementations are small and easy to port to new languages, and the end result is a smooth and interesting experience for your users. In short, BlurHash takes an image and gives you a short string (only 20-30 characters!) that represents the placeholder for this image. You do this on the backend of your service and store the string along with the image. -

CCM (C# Collections Mapper)
The CCM is a mini ORM, working with the database and C# collections
CCM is a solution for the data management layer in the combination of Sql Server with a C # application. In whole this is a strongly typed entity mapper projecting the application's business logics onto database tables using T-SQL stored procedures. CCM allows you to implement fairly complex data structures in your application, without bothering about difficult and tedious questions of data acquisition and conversion issue, allowing you to pay more attention to the develop of business logic and UI. There no need to worry about migrations, context, etc. At the same time, ORM completely relieves the developer from direct communicating with ADO - datasets, tables, rows, and other data aceess component, to track connections, commands or operate with adapters because ORM works at a higher level of data abstraction. At the same time you will be completely protected from memory leaks and free to create complexity application logic at the primary data level. -
