背景

Winscope这个开发工具其实每个安卓版本都在更新，而且每个版本的编译方法都有所不同，一般新版本Winscope和设备安卓版本还要进行匹配，不然可能会存在一定的兼容性问题。
今天受vip学员的求助,我们来探索aosp16版本Winscope编译全过程及相关的新特性体验。

环境：
ubuntu 20.04
aosp版本：android-16.0.0_r2,

建议可以先看aosp14，15版本的Winscope编译干货文章,不然可能直接上手有难度：

学员投稿：ubuntu20虚拟机编译aosp15的winscope

https://mp.weixin.qq.com/s/8RwOI_aq1LVMSfmmPJsHfw

正常编译步骤：

在本地构建 Winscope
请按照以下步骤设置您的 PC，以便运行 Winscope 跟踪器：

下载 Android 源代码。
导航到 Winscope 文件夹：

cd development/tools/winscope
使用以下命令安装依赖项：

npm install
如需查看可用命令的列表，请运行以下命令：npm run

使用以下命令构建所有生产和测试目标：

npm run build:prod
使用以下命令运行 Winscope：

npm run start

但是往往没有一帆风顺的事情，这次就遇到了好几个坑。

网络问题

执行npm run build:prod，新版本会google网站去Fetch相关的一些仓库
报错，导致Failed to connect to android.googlesource…
在这里插入图片描述
在以前14，15初期rc版本，其实不会有这个网络问题，那时候不会去Fetch，那么现在这个问题怎么办呢？
那只能考虑楼梯啦，具体方法大家自己考虑哈，反正要解决你的terminal可以访问google既可以。

webpack: not found问题：

test@test:~/disk_2T/aosp16/development/tools/winscope$ npm run start

> winscope@0.0.0 start
> webpack serve --config webpack.config.dev.js --open --hot --port 8080

sh: 1: webpack: not found

解决办法：

1 手动安装webpack

npm install webpack -g

added 77 packages in 2s

11 packages are looking for funding
  run `npm fund` for details

2、再执行命令：

npm run start
发现会要我安装webpack-cli，选yes既可以

npm run start

> winscope@0.0.0 start
> webpack serve --config webpack.config.dev.js --open --hot --port 8080

CLI for webpack must be installed.
  webpack-cli (https://github.com/webpack/webpack-cli)

We will use "npm" to install the CLI via "npm install -D webpack-cli".

99 errors have detailed information that is not shown.
Use 'stats.errorDetails: true' resp. '--stats-error-details' to show it.

webpack 5.91.0 compiled with 99 errors in 11963 ms

明显发执行npm run start启动会有报错99 个errors。

这里猜测可能是上面没有安装webpack就启动编译导致。

3、重新进行npm run build:prod

WARNING in webpack performance recommendations: 
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.
For more info visit https://webpack.js.org/guides/code-splitting/

webpack 5.91.0 compiled with 3 warnings in 20168 ms

没有编译出错

4、重新进行npm run start

test@test:~/disk_2T/aosp16/development/tools/winscope$ npm run start

> winscope@0.0.0 start
> webpack serve --config webpack.config.dev.js --open --hot --port 8080

这次发现一切正常，浏览器也显示出来了相关网页

执行winscope_proxy.py相关的报错

按照以前套路执行

python3 $ANDROID_BUILD_TOP/development/tools/winscope/src/adb/winscope_proxy.py

命令但是执行后发现python版本太老了，要升级到python3.10+版本

test@test:~/disk_2T/aosp16$ python3 $ANDROID_BUILD_TOP/development/tools/winscope/src/adb/winscope_proxy.py
Traceback (most recent call last):
  File "/home/test/disk_2T/aosp16/development/tools/winscope/src/adb/winscope_proxy.py", line 47, in <module>
    assert version.major == 3 and version.minor >= 10, "This script requires Python 3.10+ and ADB installed and in system PATH."
AssertionError: This script requires Python 3.10+ and ADB installed and in system PATH.

升级python3.10:

test@test:/usr/bin$ sudo apt install -y python3.10 python3.10-distutils

升级后看看是否已经有了3.10

test@test:/usr/bin$ ls | grep python
dh_python2
python
python2
python2.7
python3
python3.10  ------------已经有了
python3.8
python3.8-config
python3-config
python3-futurize
python3-pasteurize
python3-unidiff
x86_64-linux-gnu-python3.8-config
x86_64-linux-gnu-python3-config

那么接下来再执行

python3.10 $ANDROID_BUILD_TOP/development/tools/winscope/src/adb/winscope_proxy.py

在这里插入图片描述
正常运行起来了winscope_proxy.py

aosp16的Winscope重大亮点功能

1、多了input相关的信息

在这里插入图片描述

2、View Capture更加完善
