给我这样的傻瓜一个更详细的答案:

Open the SDK manager Select the SDK Tools tab. Download – Make sure that intel x86 Emulator Accelerator (HAXM) is downloaded. Install – Now that HAXM is downloaded, make sure it is installed. In the SDK window it will show you where the SDK is located on your computer: Click/tap 3 times quickly to highlight this text and copy the folder location. Open the file explorer and paste in the file location. From here you can search “hax” to find the folder location for HAXM stuff. Once a file comes up in the search results, right click and select “open file location”. For me the location was C:\Users\Datu1\AppData\Local\Android\Sdk\extras\intel\Hardware_Accelerated_Execution_Manager . Find the file intelhaxm-android.exe and open/run it. Follow the instructions when it runs. You may wish to run haxm_check as an administrator (it’s in this same folder), but it may or may not work for you. The surefire way to tell if you can run hardware acceleration and if it’s enabled is to go to your computer’s bios settings from the startup menu. BIOS settings – Make sure hardware acceleration is enabled in your BIOS settings. The way to do this may vary a bit from system to system. You may need to press f10 or esc on startup. But with most (updated) Windows 10 computers you can access the BIOS settings by doing the following: type “advanced startup” in the Windows search bar; click on “change advanced startup uptions:” when it comes up. Click “Restart now”. After your computer restarts click on Troubleshoot. Click advanced options >firmware settings, then restart to change EUFI firmware settings. Wait for the restart then select the menu option for bios settings. With Intel processors the steps will be as follows or similar: Press the right arrow to go to the Configuration tab. Arrow down to Intel Virtual/Virtualizaion Technology and turn it on (should say Enabled). Exit and save changes. If Virtual Technology was previously disabled in your bios settings You will need to run the intelhaxm-android.exe file now to install haxm. Try restarting Android Studio and running your emulator again. If it’s still not working, restart your computer and try again, it should work.

注意:如果你打开了Windows Hyper-V，这将导致你不能运行haxm。如果你有hyper - v的问题，确保它在你的设置中被关闭:在Windows栏中搜索“hyper”;搜索结果会显示“打开或关闭Windows功能”。然后确保所有的Hyper-V盒子都是未勾选的。

Right click on your my computer icon and the CPU will be listed on the properties page. Or open device manager and look at the CPU. It must be an Intel processor that supports VT and NX bit (XD) - you can check your CPU # at http://ark.intel.com Also make sure hyperV off bcdedit /set hypervisorlaunchtype off XD bit is on bcdedit /set nx AlwaysOn Use the installer from https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager If you're using Avast, disable "Enable hardware-assisted virtualization" under: Settings > Troubleshooting. Restart the PC and try to run the HAXM installation again

在Mac上，Android SDK安装在:/Users/username/Library/Android/ SDK /，因此，你需要运行脚本sudo，如下所示:

sudo sh /Users/username/Library/Android/sdk/extras/intel/Hardware_Accelerated_Execution_Manager/silent_install.sh

如果一切顺利，脚本将输出消息:“通过静默安装!”

然后，重新启动Android Studio并使用所需的AVD运行应用程序。

我在这上面浪费了太多时间，我发现问题出在AVAST上!! 如果你在你的系统中安装了AVAST，你必须:

转到设置选项卡—>故障排除，然后您应该取消选中 “启用硬件辅助虚拟化”

重启电脑，如果没有安装intelhaxm-android.exe，请安装。 你可以找到它:

C:\Users\ {YOURUSERNAME} \ AppData \本地Android \ sdk \ \配件\ \ Hardware_Accelerated_Execution_Manager英特尔

如果您最近在Windows操作系统上安装了Docker，则需要关闭Hyper-V特性。请参见安装HAXM时“不支持VT”的顶部答案

我也有同样的问题。在我的案例中，我发现有两个问题导致了这个问题

我有Hyper-V运行，我认为如果任何虚拟化程序运行，你需要卸载 我使用的是标准帐户，而不是管理员帐户
