变量名:ANDROID_SDK_HOME 变量值:C:\Users>用户名

为我工作。

在AVD管理器中，使用谷歌api的目标设置AVD后，运行时得到错误。

详细信息显示:“AVD未知目标'谷歌Inc.:谷歌api:......”

在安装期间(在Win7系统上)，我选择了一个SDK目录位置，而不是接受c:\ users \… 然后我将该目录添加到环境变量path中 命令行:android列表目标确实显示了两个谷歌api。

设置ANDROID_SDK_HOME到我的安装路径修复了avd运行错误。

我关注了https://www.mysysadmintips.com/windows/clients/761-move-android-studio-avd-folder-to-a-new-location。

Start copying a folder "C:\Users\user\.android\avd" to "D:\Android\.android\avd" (or something else). Close Android Studio and running emulators. Press Win + Break and open Advanced System Settings. Then press Environment Variables. Add a user variable ANDROID_SDK_HOME. (I didn't experiment with ANDROID_AVD_HOME.) In Variable value field write D:\Android. If you also moved SDK to another folder, change ANDROID_HOME (I forgot to change it and some emulators didn't launch, see https://stackoverflow.com/a/57408085/2914140). Wait until the folder will finish copying and start Android Studio. Open Android Virtual Device Manager and see a list of emulators. If you don't see emulators and they existed, then probably you entered wrong path into user variable value in step 3. In this case close AS, change the variable and open AS again. Start any emulator. It will try to restore it's state, but it sometimes fails. A black screen can appear instead of Android wallpaper. In this case you can: a. Restart your emulator. To do this close running emulator, then in AVD Manager click Cold Boot Now.

b.如果这没有帮助，打开模拟器设置，在文件“D:\Android\. Android\ avd\Pixel_API_27.ini”中找到。

更改路径到一个新的AVD文件夹。重新启动模拟器。

删除旧的AVD文件夹从“C:\Users\user\.android\ AVD”

我认为最简单的方法是从C:\Users[USER]移动avd文件夹。然后在C:\Users[USER]中创建一个指向它的符号链接。Android同名。

如果你想知道如何做到这一点，首先安装链接外壳扩展。在文件夹移动后，右键单击它，选择选择链接源，然后右键单击。android文件夹，然后在Drop As…子菜单选择符号链接。

In Windows 10 I had that problem because My C Drive was getting full and I had needed free Space, AVD folder had 14 gig space so I needed to move that folder to another driver, first answer not work for Me so I tested another way to fix it this problem, I make a picture for you if you have the same problem, you don't need to move all of the files in .android folder to another drive (this way not work) just move avd folders in ....android\avd to another drive and open .ini files and change avd folder path from that file to the new path. Like this image:

我希望这对你有用。

注意:小心在ini文件的路径之前和之后有一个你看不到的单独的字符，如果你删除了那个字符，它就不起作用了

根据官方文档https://developer.android.com/studio/command-line/variables.html，您应该更改ANDROID_AVD_HOME environment var:

Emulator Environment Variables By default, the emulator stores configuration files under $HOME/.android/ and AVD data under $HOME/.android/avd/. You can override the defaults by setting the following environment variables. The emulator -avd command searches the avd directory in the order of the values in $ANDROID_AVD_HOME, $ANDROID_SDK_HOME/.android/avd/, and $HOME/.android/avd/. For emulator environment variable help, type emulator -help-environment at the command line. For information about emulator command-line options, see Control the Emulator from the Command Line. ANDROID_EMULATOR_HOME: Sets the path to the user-specific emulator configuration directory. The default location is $ANDROID_SDK_HOME/.android/. ANDROID_AVD_HOME: Sets the path to the directory that contains all AVD-specific files, which mostly consist of very large disk images. The default location is $ANDROID_EMULATOR_HOME/avd/. You might want to specify a new location if the default location is low on disk space.

在修改或设置ANDROID_AVD_HOME后，你必须将所有内容移动到~user/。Android /avd/到你的新位置，并改变路径到每个模拟器的ini文件，只需用你的新路径替换它
