About Wikipedia Android

This repository contains the source code of the official Wikipedia app for Android, maintained by the Wikimedia Foundation. The app lets people read Wikipedia articles on a phone or tablet, and the code is released under the Apache-2.0 license. It is written mainly in Kotlin with some Java.

The project uses the MediaWiki and REST APIs to get content, and its topics point to modern Android components such as coroutines and view models. Documentation for developers is kept on a wiki rather than in the repository, and issues are reported through the Wikimedia bug tracker on Phabricator instead of GitHub.

It is a mobile client for the public Wikipedia service, so there is nothing to self-host. It is of interest to Android developers who want to contribute to a large open-source app, study how a major reading application is built, or build on the Wikimedia APIs.
