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.

执行adb命令行。像这样

adb devices

如果你的手机里有android9，你必须在Android Studio更新Android SDK。

打开Android studio，进入设置。 系统设置\安卓 选择Android SDK(你会看到SDK的新版本) 点击应用 您的移动电话将需要访问现在的MIDI模式。

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.

下面是该方法的源代码

要启动并运行该功能:

Follow steps at https://developers.google.com/chrome-developer-tools/docs/remote-debugging Install Windows USB driver http://developer.samsung.com/android/tools-sdks/Samsung-Android-USB-Driver-for-Windows Install Android SDK http://developer.android.com/sdk/index.html Install Android SDK Platform-tools http://developer.android.com/sdk/installing/adding-packages.html (this step was blocked on corporate wifi so I installed the single ADB package it required https://forum.xda-developers.com/showthread.php?t=2317790) Use command prompt to run ADB, in cmd go to the install directory of the ADB tools and type: adb.exe (might need to start and stop ADB using adb kill-server and adb start-server) Connect phone and browse to about:inspect in Chrome on desktop, ensuring a Chrome browser is open on your device

按照上面的步骤，我得到RSA密钥指纹提示接受，然后我在Chrome中看到我的设备。

绝对不像我想象的那么容易，但至少它现在起作用了。

2016年2月24日更新

所以我升级到Windows 10，现在有一台三星Galaxy S5，设备分别运行Chrome v48.0.2564.116 m和v48.0.2564.95 m。按照谷歌文档中的步骤……它又不能工作了，没有RSA密钥提示。所以我开始按照上面的步骤，并认为必须有一个更快的方法，因为Android SDK的下载超过1GB。

这次我试着:

Follow steps at https://developers.google.com/chrome-developer-tools/docs/remote-debugging Install Windows USB driver http://developer.samsung.com/android/tools-sdks/Samsung-Andorid-USB-Driver-for-Windows (the PC alerted me saying it was already installed but I still did it anyway) Install the single ADB package required https://forum.xda-developers.com/showthread.php?t=2317790) Go to the ADB install folder which for me was C:\Program Files (x86)\Minimal ADB and Fastboot\ Open command prompt and run adb devices (alternatively I could have run adb start-server but the prior gives a more informational response)

现在，Chrome打开我的手机和Chrome://inspect/打开我的桌面上，我可以看到检查选项。

下一个问题:每次重启Windows时，我都需要重复相同的步骤。要解决这个问题:

打开文本编辑器，复制到“C:\Program Files (x86)\Minimal ADB and Fastboot\ ADB”设备中 将该文件保存为adb.bat在Windows启动文件夹中，位于C:\ProgramData\Microsoft\Windows\开始菜单\Programs\ Startup

注意，只要是.bat文件，文件就不需要被称为adb.bat。您复制到文件中的命令具有默认安装路径，您可能需要更改该路径以进行设置。

现在我有Chrome检查功能工作时，我需要它。

感谢并大声向所有为这个问题提供答案的人喊话，他们帮助我对我的答案进行了有用的更新。请给其他你认为对你有帮助的答案署名。

我解决了这个问题，没有安装任何三星或Android SDK驱动程序，也没有选择MIDI或图像传输选项，正如上面横跨几年的许多答案所详细描述的那样。

对我来说，在Windows 10上，这个问题是由Windows 10内置的名为Your Phone的应用程序引起的。我只需要在高级设置中修复应用程序。可能有一种更简单的方法来访问应用程序的设置，但我是这样访问的:

系统设置 添加或删除程序 上单击“您的手机” 列表 选择高级选项 在“重置选项”下选择“修复”

在此之后，当我重新连接并在我的Android手机(三星A30)上切换USB调试时，我的手机提示我批准RSA密钥指纹，这使得Chrome DevTools最终识别我的手机。
