This library can be integrated into existing Android apps. Android is by far the most popular mobile operating system in China. Even though Google Play is blocked in China, there are many other ways to get Android apps onto your phone. We hope that this library is used by a wide variety of developers, but in particular we hope that larger organizations, whose websites are blocked in China, consider incorporating this library into their exisiting apps.

We have created demo versions of how this code can be integrated into existing apps, so that you can see the library in action and can see that it works. Demo versions have been created for Wikipedia (“the world’s largest source of information”) and DuckDuckGo, the world’s leading privacy-based search engine.

All of the world's largest internet companies, from Facebook, to Google, to Twitter, could theoretically incporate this code into their existing Android apps and be able to reach their audiences in China free of censorship controls.

If you are a developer, we hope that you and your peers can take the time to try out the code. If you know of someone who might find this code useful, please do direct them to this post. We stand ready to answer any questions which you may have and to provide assistance in any way we can.
