Magnus Jedvert c252dabbd6 CameraEnumerationAndroid: Make getSupportedFormats() an interface
Enumerating camera capabilities in the deprecated android.hardware.Camera interface is really slow because of the need to open and release the camera. By making getSupportedFormats() an interface, we allow apps the opportunity to inject their own implementation, such as storing the supported formats offline in the device's internal storage. It will also be possible to add an implementation of getSupportedFormats() using the new android.hardware.Camera2 interface in a follow-up CL.

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.
