Question

启动时，我在logcat中收到以下错误消息。

org.chromium.chrome E/chromium: [ERROR:devtools_http_handler.cc(249)] Cannot start http server for devtools. Stop devtools.

我正在运行Chromium内部版本65.0.3317.0。在早期版本的Chromium 54.0.2840.9上不会发生此错误，并且铬devtools可以正常工作。当我尝试使用devtools检查远程android设备时，将打开空白标签，错误为HTTP/1.1 404 Not Found。

我还将在引发错误的文件中附加不同的内容。

Chromium 54-devtools_http_handler.cc

您会注意到65版本正在对ip_address值进行布尔检查，而54版本仅检查server_socket。

我意识到有一个未答复的帖子Cannot start http devtools，但已发布了3个月，没有任何回复。

无法启动devtools的http服务器。停止devtools /未找到HTTP / 1.1 404
