"""Builds the WebRTC Video Demo for Android.

This script is designed as an annotation script to be run by a Chrome Buildbot.

PREREQUISITES: You must have built WebRTC with the right environment set (the
one you get when sourcing build/android/envsetup.sh) before building with this
script.

NOTICE: To build successfully, you have to have Ant installed and have your
.gclient file setup with the target_os = ["android"] variable appended to the
last line of your WebRTC solution, so it looks like this:
];target_os = ["android"]
Then run 'gclient sync' to sync out the required Android SDK and NDK files into
the third_party directory.
If you want to get additional platform-specific dependencies in the same
checkout, add them to the list too, e.g. target_os = ["android", "unix"].
