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。

我已经安装了HAXM，但它是一个较旧的版本。然后我从SDK管理器更新，然后模拟器工作!

我遇到了同样的问题，但在我的BIOS上关闭Hyper-V并启用VT-x后，我仍然无法安装intelhaxm-android.exe程序。

为了解决我的问题，我不得不关闭Windows防御程序内存完整性

检查这里的步骤-> https://github.com/intel/haxm/issues/105

在android sdk管理器中，它说它已经安装了硬件加速器，但我认为它只是下载而不是安装。我只是手动安装了intelhaxm-android.exe，它为我工作。

加上我安装了docker，有一些答案禁用Hyper-V功能，因此我也这样做了，但不确定是否有帮助。

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

你应该先在sdk管理器上安装英特尔硬件加速，然后才能开始在AVD管理器上创建你的虚拟设备
