win10系统下编译webRTC的Android版

其他 2020-07-23 13:52:41 阅读次数: 0

一、配置环境

1、Android的编译，需要在Linux下进行，所以 《虚拟机》+ 《Ubuntu》 先准备好。Ubuntu需要预留50G的空间，当然40G应该也可以吧。反正20G是可定不行的。我一开始是20G，后来下载完的webRTC实在太大了，又重新卸载并安装了Ubuntu（当然，如果你会扩容，就忽略我的做法）。

2、安装git工具

sudo apt-get install git

3、在终端上执行脚本。（前两条，一条一条的输入，后面的可以一次性复制过去）

4、指定同步目录：我在home/user下面，新建了一个webRTC的文件夹，并进入，即home/user/webRTC 目录，设置为当前目录。

#指定当前目录为同步目录，也可以指定其他路径
export WORKSPACE=`pwd`

5、切换到当前目录（cd $WORKSPACE），然后下载并安装depot_tools

cd $WORKSPACE
rm -rf depot_tools && git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

cd $WORKSPACE/depot_tools && git checkout gitlab
chmod +x $WORKSPACE/depot_tools/cipd

export PATH=$PATH:$WORKSPACE/depot_tools

6、同步webRTC（最后一行，开始下载，然后等待漫长的一个多小时）

rm -rf $WORKSPACE/webrtc && mkdir $WORKSPACE/webrtc
cd $WORKSPACE/webrtc && gclient config --name src https://chromium.googlesource.com/external/webrtc.git@gitlab

export CDS_CLANG_BUCKET_OVERRIDE=http://120.92.49.206:3232/chromiumsrc/commondatastorage/raw/master/public/chromium-browser-clang

#cd ~/depot_tools; git fetch; git reset --hard origin/gitlab; chmod +x ~/depot_tools/cipd

cd $WORKSPACE/webrtc && gclient sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab

二、编译

安装依赖项时，需要sudo 权限。 

编译生成的库，存放在 src/out/Release

编译完成后，就可以在src/out/Release/apks目录下找到AppRTCMobile.apk了

# 安装依赖
apt-get install -y software-properties-common # 前面加：sudo
add-apt-repository -y ppa:openjdk-r/ppa  # 前面加：sudo
 
./build/install-build-deps-android.sh    # src/build/有这个sh，直接sudo 执行


# 添加安卓平台
cd $WORKSPACE/webrtc
echo "target_os = [ 'android' ]" >>.gclient


# 同步
export PATH=$PATH:$WORKSPACE/depot_tools
export CDS_CLANG_BUCKET_OVERRIDE=http://120.92.49.206:3232/chromiumsrc/commondatastorage/raw/master/public/chromium-browser-clang

# 时间稍长
cd $WORKSPACE/webrtc && gclient sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab


# 编译
cd $WORKSPACE/webrtc/src

gn gen out/Release_arm64 "--args=is_debug=false target_os=\"android\" target_cpu=\"arm64\""

ninja -C out/Release_arm64

编译其他版本：

a)编译arm debug版本
gn gen out/Debug_arm32 "--args=target_os=\"android\" target_cpu=\"arm\""
ninja -C out/Debug_arm32

b)编译arm64 debug版本
gn gen out/Debug_arm64 "--args=target_os=\"android\" target_cpu=\"arm64\""
ninja -C out/Debug_arm64

c)编译arm release版本
gn gen out/Release_arm32 "--args=target_os=\"android\" target_cpu=\"arm\" is_debug=false"
ninja -C out/Release_arm32

d)编译arm64 release版本
gn gen out/Release_arm64 "--args=target_os=\"android\" target_cpu=\"arm64\" is_debug=false"
ninja -C out/Release_arm64

三、编译过程，出现的问题：

当程序编译到一半出错时，输入：ninja -C out/Release_arm64 >> release_arm64.log

即可得到错误日志，主要问题如下：

File "/usr/lib/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1340, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

ninja: build stopped: subcommand failed.

1. 怀疑是python和java版本的问题，查看python版本，和java版本：

执行：sudo apt-get install openjdk-8-jre-headless， 然后再执行ninja ，并没有解决。

2. 从网上查的解决方案：sudo apt-get install git git-core，然后再执行ninja ，并没有解决。

3. 怀疑是64位编译不过去，直接编译debug32位的，试一下， 还是不行。

4. 认真看看报错信息，发现：

在out/debug或者release的路径下，就没有这两个文件，所以报错了。
gen/base/android_runtime_jni_headers/base/jni/Runnable_jni.h 

gen/base/android_runtime_jni_headers/base/jni/Runtime_jni.h

再进一步检查，发现在 下面这句话执行的时候，就报错了。  

./build/install-build-deps-android.sh

错误信息如下：

Aborted (core dumped)
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi'
E: Sub-process returned an error code

网上找的解决方案（参考链接：https://forum.siduction.org/index.php?topic=6174.0）：

先执行： sudo apt-get remove libappstream3 // 好像是不让16.04版本更新，

然后执行：sudo ./build/install-build-deps-android.sh  // 这里卡了好久，直接ctrl+z 停了。最后也还是不行。

5. 看看有哪些进程开着的，kill掉一些进行，然后重新执行【安装依赖】，最后证明，是路径没有搞对，最后通过了。

关机重启，重新执行，通过。

 

c++编译出来的动态库：*.so .

但是java不能直接用，需要引用：libjingle_peerconnection_java.jar，←这里面的jar文件 将来都可能会用到。

 

四、测试

编译好之后，apk在这里：webrtc/src/out/release_aem64/apks/AppRTCMobile.apk

把这个apk，放在Android机上，安装。

打开这个浏览器：https://appr.tc/ ，生成随机码，JOIN, 然后手机端输入相同的号码，进行测试。

我这里出现的问题：

浏览器端提示这个错误：
Messages:  
WebSocket open error: WebSocket error.
WebSocket register error: WebSocket error.

手机端提示这个错误：
Connection error
Room IO error:
java.net.SocketTimeoutException:
connect timed out
