无法查看由Android SDK中的Systrace工具生成的HTML跟踪报告 [英] Unable to view HTML trace report generated by Systrace tool in Android SDK
问题描述
我正在尝试使用Android SDK中的 Systrace 工具生成跟踪报告，但是无法在浏览器中查看该报告.它为空白，不包含任何信息.我在一些论坛上读到需要在Chrome浏览器中打开报告，我也使用Chrome打开了报告，但报告为空白.
I am trying to generate trace reports with Systrace tool in the Android SDK, but I cant view the report in the browser. It is blank and does not contain any information. I read in some forums that I need to open the report in Chrome browser, I opened it with Chrome as well but the report is blank.
我已经从开发人员选项中启用了USB调试，并且设备正在运行Android 4.2，并且我正在使用Android SDK中的 DDMS 工具生成跟踪.
I have enabled USB Debugging from the Developer Options and device is running Android 4.2 and I am using DDMS tool from the Android SDK to generate the traces.

第二，我认为这是Google确认的错误.

这似乎是因为现代版本的Chrome已弃用Object.observe函数[1] [2].
