Android·性能分析systrace报错

1.systrace的使用

在window10系统下的操作
通过Android studio 底下 Terminal 进入到 /sdk/platform-tools/systrace/ 目录下
然后 Terminal 里面输入如下命令 systrace.py [options] [categories]
options 用 -o mytrace.html -t 10
categories 用 sched freq idle am wm gfx view binder_driver hal dalvik camera input res

即输入：systrace.py -o mytrace.html -t 10 sched freq idle am wm gfx view binder_driver hal dalvik camera input res

然后报如下的错：

Traceback (most recent call last):
  File "E:\sdk\platform-tools\systrace\systrace.py", line 48, in <module>
    from systrace import run_systrace

这时说明只安装了python2.7， 我用的Android studio3.4版本因此必须安装python2.7。
报这个错说明还需要安装pywin32.
python2.7与pywin32软件路径：
https://www.python.org/downloads/release/python-270/
https://github.com/mhammond/pywin32/releases
打包好的在csdn，地址如下：
https://download.youkuaiyun.com/download/jfj12345678/11244570
安装完就可以继续操作了。
剩下的网上挺多的就不叙述了，如果没找到的推荐两篇。
