This CL is part II in a major refactoring effort. See https://webrtc-codereview.appspot.com/33969004 for part I. - Removes unused code and old WEBRTC logging macros - Now uses optimal sample rate and buffer size in Java AudioTrack (used hard-coded sample rate before) - Makes code more inline with the implementation in Chrome - Adds helper methods for JNI handling to improve readability - Changes the threading model (high-prio audio thread now lives in Java-land and C++ only works as proxy) - Simplified the delay estimate - Adds basic thread checks - Removes all locks in C++ land - Removes all locks in Java - Improves construction/destruction - Additional cleanup Tested using AppRTCDemo and WebRTCDemo APKs on N6, N5, N7, Samsung Galaxy S4 and Samsung Galaxy S4 mini (which uses 44.1kHz as native sample rate).

This directory contains an app for measuring the total delay from the native
OpenSL implementation. Note that it just loops audio back from mic to speakers.
Prerequisites:
- Make sure gclient is checking out tools necessary to target Android: your
.gclient file should contain a line like:
target_os = ['android']
Make sure to re-run gclient sync after adding this to download the tools.
- Env vars need to be set up to target Android; easiest way to do this is to run
(from the libjingle trunk directory):
. ./build/android/envsetup.sh
Note that this clobbers any previously-set $GYP_DEFINES so it must be done
before the next item.
- Set up webrtc-related GYP variables:
export GYP_DEFINES="$GYP_DEFINES java_home=</path/to/JDK>
enable_android_opensl=1"
- Finally, run "gclient runhooks" to generate Android-targeting .ninja files.
Example of building & using the app:
cd <path/to/repository>/trunk
ninja -C out/Debug OpenSlDemo
adb install -r out/Debug/OpenSlDemo-debug.apk
