Android抓trace报错：Failed to open /data/misc/perfetto-traces/xxx. If you get permission denied in /data/misc/perfetto-traces, the file might have been created by another user, try deleting it first. (errno: 13, Permission denied)

报错如下：

Failed to open /data/misc/perfetto-traces/xxx. If you get permission denied in /data/misc/perfetto-traces, the file might have been created by another user, try deleting it first. (errno: 13, Permission denied)

解决，依次执行以下命令：

adb root
adb shell rm -rf /data/misc/perfetto-traces/
adb shell setprop persist.traced.enable 0


等待一段时间


adb shell setprop persist.traced.enable 1
adb unroot
