perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.

library to load data for your UI that survives configuration changes.

AndroidX library to write trace events to the system trace buffer.

animates motion in the UI with starting and ending layouts.

AndroidX library to render vector graphics.

Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.

AndroidX library to display Views or Fragments in a swipeable format.

replaces AndroidX ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.

Simplify Android Storage Access Framework for file management across API levels.

An image loading and caching library for Android focused on smooth scrolling

Capacitor plugin to download and share files for the Web, Android and iOS.

plugins for Capacitor.

an object graph serialization framework for Java.

a very small Java library that provides high performance reflection by using code generation.

a fast and compliant streaming JSON parser/writer with a StAX-like API and support for marshalling/unmarshalling POJOs via annotations.

an extensible media player library for Android

a proprietary protocol developed by Google that enables mobile devices and personal computers to initiate and control playback of Internet-streamed audio/video content on a compatible device (see Wikipedia for details).

Google Mobile Services in terms of the Android library refers to Google Play Services, a proprietary background service and API package for Android devices which is not part of the Android Open Source Project (AOSP). The library does not contain those services (i.e. it usually requires the Google Framework, often referred to as „GApps“, being installed on the device), but allows an app to communicate with them. Be aware this usually goes along with transferring at least parts of your personal data to the Google network.

library to help with material design guidelines.

a set of core libraries that includes new collection types (such as multimap and multiset), immutable collections, a graph library, functional types, an in-memory cache, and APIs/utilities for concurrency, I/O, hashing, primitives, reflection, string processing, and much more.

provides kryo (v2 and v3) serializers for some jdk types and some external libs like e.g. joda time.

NoSQL data storage for Android.

specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.

The Kotlin Programming Language

library support for Kotlin coroutines.

A modern I/O API for Java to make it much easier to access, store, and process your data.

formerly known as PhoneGap: enables software programmers to build applications for mobile devices using CSS3, HTML5, and JavaScript instead of relying on platform-specific APIs.

Chromium WebView helpers
