| 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 |
