我正在尝试编译 WebRTC Native Stack 来构建libwebrtc.aar但不幸的是无法理解出了什么问题。
系统信息：
Distributor ID: Ubuntu
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Codename: bionic
Java-Version: OpenJDK-8-JDK
Python-Version: Python 2.7.17
我已按照中提供的完整步骤进行操作Android 官方 WebRTC 本机开发 http://webrtc.github.io/webrtc-org/native-code/android/。这些步骤已完成，无需任何操作中断每一步都需要时间才能完成。然后，我必须安装构建源代码所需的所有依赖项。
./build/install-build-deps.sh
在编译代码之前，我还签出了特定的 git 分支以进入不同的可用 WebRTC 版本，以列出使用此 git 命令的所有分支。
git branch -r
我正在分享最新的 Git 分支：
我已经尝试过每个 git 分支branch-heads/60 to branch-heads/m79，并且每个分支在使用编译命令时都会遇到不同的问题。我已经尝试过这两个过程来构建库，例如：
1- 使用 AAR 构建工具 (./tools_webrtc/android/build_aar.py)
confu@ubuntu:~/webrtc_android/src$ tools_webrtc/android/build_aar.py

I also checked in the secondary tree for:

2- 使用手动编译（gn gen out/Debug --args='target_os="android" target_cpu="arm"')

You set the variable "java_files" here and it was unused before it went
