History

- Centralise compileSdkVersion, targetSdkVersion and
  buildToolsVersion in a single place for gradle.
- Bump compileSdkVersion and targetSdkVersion to 24.
- Bump com.android.tools.build version to re-enable
  instant start.
- Bump targetSdkVersion in manifests (needed for
  internal builds).
- Use standard expandable_list_item from Android in
  the demo app, since ours doesn't look right when
  targeting API level 24. We were also setting the
  theme on the wrong element in the manifest, so I'm
  removing that line.

ExoPlayer Opus Extension

Description

The Opus Extension is a Renderer implementation that helps you bundle libopus (the Opus decoding library) into your app and use it along with ExoPlayer to play Opus audio on Android devices.

Build Instructions

Checkout ExoPlayer along with Extensions:

git clone https://github.com/google/ExoPlayer.git

Set the following environment variables:

cd "<path to exoplayer checkout>"
EXOPLAYER_ROOT="$(pwd)"
OPUS_EXT_PATH="${EXOPLAYER_ROOT}/extensions/opus/src/main"

Download the Android NDK and set its location in an environment variable:

NDK_PATH="<path to Android NDK>"

Fetch libopus:

cd "${OPUS_EXT_PATH}/jni" && \
git clone https://git.xiph.org/opus.git libopus

Run the script to convert arm assembly to NDK compatible format:

cd ${OPUS_EXT_PATH}/jni && ./convert_android_asm.sh

Build the JNI native libraries from the command line:

cd "${OPUS_EXT_PATH}"/jni && \
${NDK_PATH}/ndk-build APP_ABI=all -j4

In your project, you can add a dependency to the Opus Extension by using a rule like this:

// in settings.gradle
include ':..:ExoPlayer:library'
include ':..:ExoPlayer:extension-opus'

// in build.gradle
dependencies {
    compile project(':..:ExoPlayer:library')
    compile project(':..:ExoPlayer:extension-opus')
}

Now, when you build your app, the Opus extension will be built and the native libraries will be packaged along with the APK.

Notes

Every time there is a change to the libopus checkout:
- Arm assembly should be converted by running convert_android_asm.sh
- Clean and re-build the project.
If you want to use your own version of libopus, place it in ${OPUS_EXT_PATH}/jni/libopus.
