1This directory contains an app for measuring the total delay from the native
2OpenSL implementation. Note that it just loops audio back from mic to speakers.

4Prerequisites:
5- Make sure gclient is checking out tools necessary to target Android: your
6 .gclient file should contain a line like:
7 target_os = ['android']
8 Make sure to re-run gclient sync after adding this to download the tools.
9- Env vars need to be set up to target Android; easiest way to do this is to run
10 (from the libjingle trunk directory):
11 . ./build/android/envsetup.sh
12 Note that this clobbers any previously-set $GYP_DEFINES so it must be done
13 before the next item.
14- Set up webrtc-related GYP variables:
15 export GYP_DEFINES="$GYP_DEFINES java_home=</path/to/JDK>
16 enable_android_opensl=1"
17- Finally, run "gclient runhooks" to generate Android-targeting .ninja files.
