Fix problem with ipv4 over ipv6 on Android This patch fixes a problem with using ipv4 over ipv6 addresses on Android. These addresses are discovered using 'getifaddr' with interfaces called 'v4-wlan0' or 'v4-rmnet' but the Android API does not report them. This leads to failure when BasicPortAllocator tries to bind a socket to the ip-address, making the ipv4 address unusable. This solution does the following 1) Insert BasicNetworkManager as NetworkBinderInterface rather than AndroidNetworkManager. 2) When SocketServer calls BindSocketToNetwork, BasicNetworkManager first lookup the interface name, and then calls AndroidNetworkManager. 3) AndroidNetworkManager will then first try to bind using the known ip-addresses, and if it can't find the network it will instead match the interface names. The patch has been tested on real android devices, and works fine. And everything is disabled by default, and is enabled by field trial. My plan is to rollout the feature, checking that it does not introduce any problems, and if so, enabled for all.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
See here for instructions on how to get started developing with the native code.
