This should let you build AppRTCDemo without much effort. I built WebRTC distribution on 9/6/2014, extracted trunk/talk/examples/android, and it is imported to Android Studio.

It is not straightforward to build WebRTC for Android on Mac OS X.

• WebRTC can be only built on Linux.
• You need to have 6G+ disk space to build.
• Git clone takes up an hour.
• It requries a lot of libraries/packages installed.

However, it turned out that at the end of the day, you just need a few files to build it on Android.

While this requries almost no effort to build, you need:

• Android NDK installed on your machine.
• Point the NDK installation via local.properties
