Systrace输出错误 [英] Systrace Output Error

问题描述

我在android studio项目上运行systrace以便发现一些性能错误，但是在跟踪过程结束后，出现以下错误，并且如果我在chrome中打开trace.html输出文件，则跟踪视图为空:

I ran systrace on my android studio project in order to find some performance bugs but after the end of the tracing process, i get the following error and if i open the trace.html output file in chrome, the trace view is empty:

有人对此或任何建议有解决方案吗?

Anyone have a solution for this or any advice?

推荐答案

Systrace.py具有--no-compress选项.使用它应该使跟踪完成，而无需执行失败的解压缩步骤.

Systrace.py has a --no-compress option. Using it should allow the trace to complete without hitting the failing decompression step.

我的Windows 10系统上发生了同样的问题，这为我解决了这个问题.

The same problem was occurring on my Windows 10 system and this solved it for me.
