Android Studio看不到设备。

The AVD manager in Android Studio doesn't show my device but "adb devices" does show it. Am I missing something obvious here?

Android Studio的AVD管理器没有显示我的设备，但“adb设备”确实显示了它。我漏掉了什么明显的东西吗?

To change what your application defaults to when you click run or debug in Android Studio, follow these steps:

要更改在Android Studio中单击run或debug时的应用程序默认设置，请遵循以下步骤:

1. go to Run

1。去运行

2. Click on Edit Configurations

2。点击编辑配置

3. Select the project

3所示。选择项目

4. find the Target Device section under the General tab on the Android Application page.

4所示。在Android应用程序页面的General选项卡下找到目标设备部分。

That seems to be where you toggle what the project builds to. If you're importing a project it actually defaults to Emulator, not sure why.

这似乎是您切换项目构建的地方。如果您正在导入一个项目，它实际上默认为模拟器，不知道为什么。

I recently had trouble with this, and regardless of what I did(restart adb, edit adb_usb.ini, restart computer+device+swap usb port, reinstall studio etc. etc.) I just couldnt get it to work, and could not even detect my device using 'adb devices'. Finally after about 2 hours of googling and testing, someone suggested switching to PTP instead of MTP on my device. When I did this I got a popup on my device asking me to allow my mac access and suddenly everything worked(had to restart studio for it to show up there as well though).

我最近在这方面遇到了麻烦，不管我做了什么(重启adb，编辑adb_usb)。ini，重启电脑+设备+交换usb接口，重新安装studio等)我无法让它工作，甚至不能使用“adb设备”检测我的设备。最后，在google和测试两小时后，有人建议改用PTP，而不是MTP。当我这样做的时候，我的设备上有一个弹出窗口，请求我允许mac访问，然后突然所有的东西都工作了(不得不重新启动studio，以便它也能显示在那里)。

I might be bumping this thread now, but it is the first result on google search, and I had a lot of trouble finding an answer for this problem, so I thought this should be added as a solution.

我现在可能会碰到这个线程，但是它是谷歌搜索的第一个结果，我在找到这个问题的答案时遇到了很多麻烦，所以我认为这应该作为一个解决方案来添加。

On your device:

在你的设备:

Go to settings/ developer settings/ allow USB debug mode

进入设置/开发者设置/允许USB调试模式。

If 'allow USB debug mode' option is disabled. Then you might have the device currently connected to your PC. Disconnect the device and the option should now be available

如果“允许USB调试模式”选项被禁用。然后你可能会有设备连接到你的电脑。断开设备，该选项现在可用。

Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.

注意:在Android 4.2和更新版本中，默认情况下隐藏了开发者选项。要使它可用，可以到设置>的电话和tap构建7次。返回到前面的屏幕，以找到开发人员选项。

If it still doesn't help, you can google it with this expression:

如果它仍然没有帮助，你可以用这个表达式谷歌:

I had to killall adb because somehow, Android Studio managed to crash and did not want to communicate with adb anymore. Thus, my device did not show up.

我不得不杀掉所有的adb，因为Android Studio设法崩溃了，不想再和adb沟通了。因此，我的设备没有出现。

So quitting Android Studio, terminating all adb instances in Terminal and starting Android Studio again (should ask if it should enable debugging then) worked.

因此，退出Android Studio，在终端上终止所有adb实例，重新启动Android Studio(应该询问是否应该启用调试)。

It works for me by following steps below:-

它对我的工作如下:-。

If you using Windows, the device won't show up because of driver issue.

如果你使用Windows，这个设备不会因为驱动程序问题出现。

Go to device manager (just search it using Start) and look for any devices showing an error. Many androids will show as an unknown USB device and comes with exclamation mark. Select that device and try to update the drivers for it. for update part follow the link:universal adb

到设备管理器(只需要使用Start搜索它)，并寻找任何显示错误的设备。许多机器人将作为一个未知的USB设备显示，并带有感叹号。选择该设备并尝试更新驱动程序。更新部分按链接:环球亚行。

But before that, you have to update your sdk manager and make sure Google USB Driver package is installed.

但在此之前，您必须更新您的sdk管理器，并确保安装了谷歌USB驱动程序包。

When done, the driver files are downloaded into the \extras\google\usb_driver\ directory. Hints: Search "android_winusb.inf" under Windows Start and Open File Location to get the directory mentioned.

当完成时，驱动程序文件被下载到\备用\谷歌\usb_driver\目录。提示:搜索“android_winusb。inf“在Windows启动和打开文件位置，以获取所提到的目录。

Open up your device manager, navigate to your android device, right click on it and select Update Driver Software then select Browse driver software. Follow the file location path previously to install Google USB Driver.

打开您的设备管理器，导航到您的android设备，右键单击它并选择Update Driver软件，然后选择Browse Driver软件。按照前面的文件位置路径安装谷歌USB驱动程序。

Restart Android Studio and Developer Options in your android device and reconnect USB.

在Android设备上重新启动Android Studio和Developer选项，并重新连接USB。

Cheers !

In my case the following steps helped to resolve the issue:

在我的案例中，以下步骤帮助解决了这个问题:

1) Ensure the package "Google USB Driver" is installed in Android SDK Manager

1)确保在Android SDK管理器中安装“谷歌USB驱动程序”。

2) Download "ADB Driver Installer 2.0" from here

2)从这里下载“ADB驱动程序安装2.0”。

3) Run the tool downloaded and connect your smartphone; in my case it showed that the driver had been installed incorrectly and suggested to fix it

3)运行工具下载并连接智能手机;在我的例子中，它显示司机安装错误并建议修理它。

After those steps my Android Studio instantly recognised the device! Both MTP and PTP started to work.

在这些步骤之后，我的Android工作室马上就认出了这个设备!MTP和PTP都开始工作。

  ./adb devices
  

• If it displays 'List of devices attached' and a blank line below, then restart adb as follows:

  ./adb kill-server
  ./adb start-server
  

  then re-run ./adb devices and see if it picks up the device, eg as follows:

  确保你的手机在设置中有开发者选项(如果不是，去设置，关于手机(或设备)，点击安卓版本多次，直到你看到一个信息)。

• Make sure USB debugging on your phone is enabled (go to Developer Options in Settings and turn it on)

  确保你的手机上的USB调试是启用的(在设置中打开开发者选项，打开它)

In my case, and I know this is dumb, but here's what I had to do.

在我的例子中，我知道这是愚蠢的，但这是我必须做的。

I had tried all the solutions above and none worked. A good key to t-shooting is when adb devices won't list the device, then you know you aren't cooking with gas yet.

我已经试过了以上所有的方法，但没有一个奏效。一个好的关键是当adb设备不列出设备时，你就知道你还没有使用天然气。

Switching between USB modes won't have an effect until the device registers as a device over adb. You'll know when that happens because you'll get a prompt about an RSA key.

在设备注册为adb设备之前，在USB模式之间切换不会有任何效果。您将知道何时发生，因为您将得到一个关于RSA密钥的提示。

It was a relatively new install of Windows 7. Under USB in my phone's notification area, I switched to Install Driver and let it install my adb driver. In my case I was never going to get anything legit over the internet.

这是一个相对较新的安装Windows 7。在我手机通知区的USB接口下，我切换到安装驱动程序，让它安装我的adb驱动程序。在我的情况下，我永远不会在互联网上得到任何合法的东西。

Once I saw that successfully install, I switched to PTP and it all just worked.

一旦我看到成功安装，我就切换到PTP，这一切都成功了。

I also had this problem. After looking though my edge 6 the enable usb debugging was greyed out and unable to be turned on.
