请注意:根据之前的回答，修改Android tools目录下的Android .bat可能会导致问题。

如果你这样做，为了合法地将你的. Android目录定位到一个非默认位置，那么Android Studio列出的AVD(使用“Tools > Android > AVD管理器”)和sdk命令行工具“Android AVD”列出的AVD之间可能存在不一致。

我认为Android Studio，其内部AVD管理器，不使用Android .bat修改路径;它依赖ANDROID_SDK_HOME变量来定位avd。

我自己的测试表明，Android工具正确地使用ANDROID_SDK_HOME变量。

因此，就我所知，修改android.bat没有任何意义，使用环境变量应该是首选。

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

变量名:ANDROID_SDK_HOME 变量值:C:\Users>用户名

为我工作。

修改“C:\Documents and Settings{your windows login}.android\avd\”中的“virtual_android2.2.ini”文件:

target=android-8
path=E:\android_workspace\avd\virtual_android2.2.avd

移动文件夹virtual_android2.2。从“C:\文档和设置{您的windows登录}。android\avd\变成E:\android_workspace\avd\。

移动你的。android到任何你想要的地方。

然后，创建一个像这样的符号链接:

# In your home folder
$ ln -s /path/to/.android/ .

这只是告诉Linux无论何时路径~/。Android被任何应用程序引用，链接到/path/to/. Android。

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”
