This directory holds a Java implementation of the webrtc::PeerConnection API, as
well as the JNI glue C++ code that lets the Java implementation reuse the C++
implementation of the same API.

To build the Java API and related tests, build with 
OS=linux or OS=android and include
build_with_libjingle=1 build_with_chromium=0
in $GYP_DEFINES.

To use the Java API, start by looking at the public interface of
org.webrtc.PeerConnection{,Factory} and the org.webrtc.PeerConnectionTest.

To understand the implementation of the API, see the native code in jni/.

An example command-line to build & run the unittest:
cd path/to/trunk
GYP_DEFINES="build_with_libjingle=1 build_with_chromium=0 java_home=path/to/JDK" gclient runhooks && \
    ninja -C out/Debug libjingle_peerconnection_java_unittest && \
    ./out/Debug/libjingle_peerconnection_java_unittest
(where path/to/JDK should contain include/jni.h)

During development it can be helpful to run the JVM with the -Xcheck:jni flag.
