The easiest way to get started is using the official prebuilt libraries available at JCenter. These libraries are compiled from the tip-of-tree and are meant for development purposes only.
On Android Studio 3 add to your dependencies: implementation 'org.webrtc:google-webrtc:1.0.+'
On Android Studio 2 add to your dependencies: compile 'org.webrtc:google-webrtc:1.0.+'
The version of the library is 1.0.. The hash of the commit can be found in the .pom-file. The third party licenses can be found in the THIRD_PARTY_LICENSES.md file next to the .aar-file.
Getting the Code
Install prerequisite software 先安装工具 depot_tools等
fetch –nohooks webrtc_android
gclient sync
This will fetch a regular WebRTC checkout with the Android-specific parts added. Notice that the Android specific parts like the Android SDK and NDK are quite large (~8 GB), so the total checkout size will be about 16 GB. The same checkout can be used for both Linux and Android development since you can generate your Ninja project files in different directories for each build config.
See Development for instructions on how to update the code, building etc.
Compiling
Generate projects using GN.
Make sure your current working directory is src/ of your workspace. Then run:
gn gen out/Debug –args=’target_os=”android” target_cpu=”arm”’
You can specify a directory of your own choice instead of out/Debug, to enable managing multiple configurations in parallel.
To build for ARM64: use target_cpu="arm64"
To build for 32-bit x86: use target_cpu="x86"
To build for 64-bit x64: use target_cpu="x64"
Compile using:
ninja -C out/Debug
Using the Bundled Android SDK/NDK
In order to use the Android SDK and NDK that is bundled in third_party/android_tools, run this to get it included in your PATH (from src/):
. build/android/envsetup.sh
Then you’ll have adb and all the other Android tools in your PATH.
Running the AppRTCMobile App
AppRTCMobile is an Android application using WebRTC Native APIs via JNI (JNI wrapper is documented here).
For instructions on how to build and run, see examples/androidapp/README.
Using Android Studio
Build the project normally (out/Debug should be the directory you used when generating the build files using GN):
ninja -C out/Debug AppRTCMobile
Generate the project files:
build/android/gradle/generate_gradle.py –output-directory $PWD/out/Debug \
–target “//examples:AppRTCMobile” –use-gradle-process-resources \
–split-projects –canary
Import the project in Android Studio. (Do not just open it.) The project is located in out/Debug/gradle. If asked which SDK to use, choose to use Android Studio’s SDK. When asked whether to use the Gradle wrapper, press “OK”.
