React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.

osmdroid is a (almost) full/free replacement for Android's MapView (v1 API) class. It also includes a modular tile provider system with support for numerous online and offline tile sources and overlay support with built-in overlays for plotting icons, tracking location, and drawing shapes.
The Google APIs Client Library for Java is a flexible, efficient, and powerful Java client library for accessing any HTTP-based API on the web, not just Google APIs.
The library has the following features:
KotlinTest is a flexible and comprehensive testing tool for the Kotlin ecosystem based on and heavily inspired by the superb Scalatest. KotlinTest provides several ways to lay out your test so that your team can pick the style they are most happy with. It also includes many matchers which allow you to write many different types of assertions easily and in a human readable way. Finally, there's helpers for things like collection testing, and future testing.
Open-source software for volunteer computing and grid computing.
Kotlin Multiplatform Mobius implementation - A functional reactive framework for managing state evolution and side-effects.
Glide is fast and efficient image loading library for Android that wraps image downloading, resizing, memory and disk caching, and bitmap recycling into one simple and easy to use interface. By default, Glide includes an implementation for fetching images over http based on Google's Volley project for fast, parallelized network operations on Android.
Tutanota is the end-to-end encrypted email client that enables you to communicate securely with anyone.
libGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, Mac OS X, Android, your WebGL enabled browser and iOS.
Project Lombok makes Java a spicier language by adding 'handlers' that know how to build and compile simple, boilerplate-free, not-quite-java code.
logback-android brings the power of logback to Android. This library provides a highly configurable logging framework for Android apps, supporting multiple log destinations simultaneously.

This open-source library contains classes that are useful for a wide range of applications using the Google Maps Android API.
This plugin provides a task to generate a HTML license report based on the configuration. (eg. licenseDebugReport
for all debug dependencies in an Android project).
Applying this to an Android or Java project will generate a the license file (open_source_licenses.html
) in the <project>/build/reports/licenses/
.

Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project. It is much easier to understand a large codebase when all the code in it is in a consistent style.
"Style" covers a lot of ground, from "use camelCase for variable names" to "never use global variables" to "never use exceptions." This project holds the style guidelines we use for Google code. If you are modifying a project that originated at Google, you may be pointed to this page to see the style guides that apply to that project.
JavaCPP provides efficient access to native C++ inside Java, not unlike the way some C/C++ compilers interact with assembly language. No need to invent new languages such as with SWIG, SIP, C++/CLI, Cython, or RPython as required by cppyy. Instead, it exploits the syntactic and semantic similarities between Java and C++. Under the hood, it uses JNI, so it works with all implementations of Java SE, in addition to Android, Avian, and RoboVM (instructions).
The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time.
When your users want to get from one location to another, don’t push them out of your application into a generic map application. Instead, keep them engaged with your application 100% of the time with in-app turn-by-turn navigation.
The Mapbox Navigation SDK is a precise and flexible platform which contains logic needed to get timed navigation instructions and enables your users to explore the world's streets. We are designing new maps specifically for navigation that highlight traffic conditions and helpful landmarks. The calculations use the user's current location and compare it to the current route that the user's traversing to provide critical information at any given moment.
A logger with a small, extensible API which provides utility on top of Android's normal Log class.
