尽管Android File Transfer已检测到设备，但Android ADB在Mac OS X中未检测到设备 [英] Android ADB not detecting device in Mac OS X although device is detected by Android File Transfer
问题描述
在安装android studio之后，我也安装了ADB。但是，由于某种原因，亚行无法检测到我的设备。为了说明一下，我想我已经完成了网上所有的基本工作，即：
After installing android studio, I installed ADB as well. However, for some reason ADB doesn't detect my device. To make a note I think I have done all the basic stuff I found online, i.e. :
- 将设备设置为开发人员模式并启用USB调试
-
电缆运行良好（当我连接设备时，Android文件传输会自动打开）
- Set device in Developer mode and enable USB debugging
Cable works well (Android file transfer automatically opens when I connect the device)
已安装Java JDK 8
Installed Java JDK 8
我正在使用Android Studio 2.2并在笔记本电脑上运行Mac OS X Sierra，而android手机正在运行Android 5.0.1（在LG Phone上）
I'm using Android Studio 2.2 and running Mac OS X Sierra on my Laptop, and the android phone is running Android 5.0.1 (on an LG Phone)
NB：我已经尝试了栈溢出的其他解决方案，但这并不是问题所在。
NB : I have tried the other solutions on stack overflow but thats not the problem.
ADB（已安装）并且可以从命令行运行，但是当我运行时：
ADB (is installed) and works from the command line, but when I run :
- 'adb usb'命令，它显示错误：未找到设备/仿真器
- 'adb devices'命令，它会打印已连接的设备列表，并在下面带有空行。
我相信这是一个特定的问题以及安装ADB或重新启动的一般解决方案在这里不起作用，因为我已经尝试了所有这些方法。
I believe this is a specific issue and the general solutions to install ADB or restart doesn't work here as I have tried all that.

我已经删除并重新安装了android studio，但仍然无法正常工作。
I have removed and reinstalled android studio, still not working.
我已删除并重新安装了adb和adb&快速启动，仍然无法正常工作。
I have removed and reinstalled adb and adb & fastboot, still not working.
我已经重新启动设备，禁用并重新启用了开发人员模式，仍然无法正常工作。
I have restarted my device, disabled and re-enabled developer mode, still not working.
很显然，我已经拔掉了好几次电缆，但仍然无法正常工作（只有Android File Transfer不断出现）
Obviously, I have unplugged and plugged the cable back in several times, still not working (only Android File Transfer keeps coming up)
以防万一我已经
Just in case, I have rooted my device, could that be the problem or that doesn't matter?
请问有人可以帮忙吗？
推荐答案
最后解决了奇怪的问题：-
Finally got the weird problem fixed :-
您基本上需要将USB模式设置为PTP模式，而不是媒体传输协议（MTP）模式。
You basically need to set the USB mode to PTP mode instead of Media Transfer Protocol (MTP) mode.
通过USB设备USB图标和调试模式图标出现在设备状态栏上。
When I connected the device via USB the USB icon and Debugging Mode Icon appeared on the status bar on the device.
如果通过从顶部向下滑动来打开控制中心，则应该看到媒体设备MTP-点按以获取更多USB选项。点按它，然后将模式切换到发送图像（PTP）模式，它会询问您是否要启用USB调试。启用它，该设备现在应该已被ADB和Android Studio识别。
If you open control centre by swiping down from the top, you should see a "Media device MTP" - Tap for more USB options. Tap it and switch the mode to "Send Images (PTP)" mode and it should ask you if you want to enable USB debugging. Enable it and the device should be recognised by ADB and Android Studio now.
感谢您提供其他解决方案的时间。
Thanks for your time to those that offered other solutions.
