IPv6Droid
APK
To actually use this app, a tunnel service is required. You can run your own tunnel service on suitable infrastructure. See IPv6DroidServer for more details.Notes:This approach towards IPv6 has subtle implications on your privacy: for IPv6 connections, you have a fixed IP and you - as a person! - are easily identifyable by all IPv6 communication partners. Also, your mobile device suddenly has an IP on which it is reachable from the outside.This app cannot be used when another VPN is active.It is not required to have a rooted device.About license:You can opt for the convenience package, and install IPv6Droid right from here. It will download, install, guide you to the setup of your account details and update from time to time as new features or bugfixes are implemented.But I am looking for supporters! So, I'd like to promote the approach that you set up a build environment (e.g. Android Studio), download the sources (see web site) and build it by yourself. That's it. You may use the tool, modify and even redistribute the sources under the terms of the General Public License. No obligations, but in this case you have the tools, you have the sources and you have the engagement that drives me to hope that you're going to play a more active part in bringing forward this client. E.g. by submitting detailed error reports, by submitting patches, by providing better artwork, writing better documentation, designing a better user experience, ...

IntentRadio
APK
Intent Radio is an android internet radio app without a graphical user interface. It is controlled exclusively through the delivery of broadcast intents.

Despite its name, Intent Radio will happily play any audio media supported natively by Android, including local content. Important: You must run the app manually at least once before Android will deliver broadcast intents. This is an Android security feature. Thereafter, even after reboots, it should not be necessary to run the app at all.
