即使按照https://developer.chrome.com/docs/devtools/remote-debugging/上列出的步骤操作，我还是无法在我的三星Galaxy S4上使用DevTools Devices功能
我的设备有Chrome v32和Chrome Beta v33，而我的个人电脑有Chrome v33和Chrome Canary v35。
我的设备上已开启USB调试，并且已安装设备驱动程序。我从未从上面的链接中得到步骤3中概述的提示，以批准RSA密钥指纹，但设备确实连接到我的PC以允许媒体传输。我甚至根据上面的链接撤销了所有USB调试授权。
我的电脑上没有任何额外安装的东西用于Android开发，这可能是问题所在。我希望利用这个功能从设备的角度来检查网页。

上面提到的答案对我都没用。然而，对我有用的是端口转发。步骤如下:
Ensure you have adb installed (steps here for windowd, mac, ubuntu) Ensure you have chrome running on your mobile device On your PC, run the following from command line: adb forward tcp:9222 localabstract:chrome_devtools_remote On running the above command, accept the authorization on your mobile phone. Below is the kind of output I see on my laptop: $:/> adb forward tcp:9222 localabstract:chrome_devtools_remote * daemon not running. starting it now on port 5037 * * daemon started successfully * Now open your chrome and enter 'localhost:9222' and you shall see the active tab to inspect.

用的是三星Galaxy S9，运行Android Pie。——2019年5月 类似于上面的答案，以及NickW的答案: 设备连接好后，不要进入设置，而是进入手机的通知栏> Android系统，然后“点击其他USB选项”。在选项下选择MIDI，您就可以开始了!
我是应用程序编程的新手，这是我在尝试使用LG G3设备进行示例程序调试时遇到的第一个问题。上面有详细说明的职位应该适用于所有人。我补充了我的经验，以防它能帮助到其他人:
I had followed instructions step by step but one. That is, installing the USB driver from my OEM. My phone kept notifying that the debugging is on (in the notification area) and I could transfer data as well as charge. That made me think that appropriate USB drivers are installed. But it wasn't. Finally I went to LG site and downloaded the USB driver for my LG G3. Right after I installed the driver and reconnected the phone to the computer via the cable, I got the RSA key prompt. My Chrome now detects it and I was able to get my app run on my phone via Android studio as well.
如果你在windows上，你需要为你的手机安装驱动程序。你可以在这里买到。
如果它仍然不工作，我已经通过手动重新启动Android调试桥来幸运地连接。更多信息在这里。
我使用过六种不同的Android设备和多种电缆，我不得不说调试器工作不稳定。有时它能看到设备，有时不能。有时重新启动Chrome会有帮助。这里有一个相关的bug https://bugs.chromium.org/p/chromium/issues/detail?id=788161，也许你可以提供你的证据。
