序言

最近在研究性能問題需要抓取trace文件。于是寫了個腳本

使用

雙擊運行批處理文件，可以開始記錄trace。而且以當前文件夾下面的。config.pbtx 作為配置文件。

（pbtx就是一個json文件。配置了需要抓取那些參數，可以通過https://ui.perfetto.dev/中的Record new trace （左側）的菜單，在右側設置最近要記錄什么內容。來生成配置文件。可以參考
Android Perfetto 系列 2：Perfetto Trace 抓取

最后的文件在Cmdline instructions菜單中顯示。

右邊下方的內容拷貝到。當前目錄，并命名為config.pbtx
記得把配置中的時間去除，這樣可以一直記錄。

在當前文件夾下新建批處理

@echo off
chcp 65001 >nul@echo off
setlocal enabledelayedexpansion:: 獲取當前目錄
echo 當前目錄: %cd%:: 使用 PowerShell 獲取時間戳
for /f "delims=" %%a in ('powershell.exe -Command "Get-Date -Format yyyyMMdd_HHmmss"') do set timestamp=%%a
echo 時間戳: %timestamp%:: 刪除舊 trace 文件
adb shell rm -rf /data/misc/perfetto-traces/trace.perfetto
timeout /t 1 >nul:: 推送配置文件
adb push config.pbtx /data/misc/perfetto-configs/config.pbtx
timeout /t 1 >nul:: 開始錄制
echo 開始記錄 trace，請按 Ctrl+C 結束錄制...
adb shell -tt perfetto --txt -c /data/misc/perfetto-configs/config.pbtx -o /data/misc/perfetto-traces/trace.perfetto:: 導出 trace 到當前目錄
adb pull /data/misc/perfetto-traces/trace.perfetto .\trace_%timestamp%.perfettoif exist trace_%timestamp%.perfetto (echo ? 文件已成功導出到當前目錄：echo     trace_%timestamp%.perfettoecho.echo 🔗 正在打開 Perfetto 官方網站，請稍后手動上傳 trace 文件。echo     1. 瀏覽器將自動打開 Perfetto UI。echo     2. 點擊左上角 ^> Open trace file^> 按鈕。echo     3. 選擇剛剛保存的 trace_%timestamp%.perfetto 文件。echo.:: 打開默認瀏覽器訪問 Perfetto UIstart "" https://ui.perfetto.dev/) else (echo ? 文件未找到，請檢查設備路徑或配置。
)pause

雙擊bat運行，要結束錄制的話，只需要按下 Ctrl+C 就可以了。

最后文件會自動保存到當前文件夾下，以時間命名。

最后還會自動打開分析網站。只需要把日志文件拖入瀏覽器就可以打開。

附帶配置

這是我的配置文件，可以記錄logcat
