Open SDK Manager and download Intel x86 Emulator Accelerator (HAXM installer) if you haven't. Now go to your SDK directory (C:\users\username\AppData\Local\Android\sdk, generally). In this directory, go to extras → Intel → Hardware_Accelerated_Execution_Manager and run the file named "intelhaxm-android.exe". In case you get an error like "Intel virtualization technology (vt,vt-x) is not enabled", go to your BIOS settings and enable hardware virtualization. Restart Android Studio and then try to start the AVD again.

显示模拟器窗口可能需要一到两分钟。

我在Oracle VirtualBox中运行模拟器时遇到了这个问题。对我来说，解决方案是修改模拟器使用ARM CPU而不是x86。

所以我有这个问题，似乎除非你在Linux上，否则你将无法使用HAXM。[编辑:这是如果你有一个AMD芯片(非英特尔)，当然，这就是问题所在]

如Android网站所述;

Many modern CPUs provide extensions for running virtual machines (VMs) more efficiently. Taking advantage of these extensions with the Android emulator requires some additional configuration of your development system, but can significantly improve the execution speed. Before attempting to use this type of acceleration, you should first determine if your development system’s CPU supports one of the following virtualization extensions technologies: Intel Virtualization Technology (VT, VT-x, vmx) extensions > AMD Virtualization (AMD-V, SVM) extensions (only supported for Linux)

正如其他人所提到的，Genymotion可能是一种解决方案。

如果你使用的是Mac，就像@pedro提到的，确保你已经通过Android SDK管理器下载了HAXM安装程序。

接下来安装它!在查找器中导航到/YOUR_SDK_PATH/extras/intel/Hardware_Accelerated_Execution_Manager/

运行并安装。mpgk到下面的。dmg

约塞米蒂:IntelHAXM_1.1.0_for_10.10.dmg Pre-yosemite: IntelHAXM_1.1.0_below_10.10.dmg El Capitan: IntelHAXM_6.0.1。请安装IntelHAXM_6.0.1。MPGK文件-它会问你是否要重新安装它。只要答应就好。

例子:

$ cd / YOUR_SDK_PATH /配件/英特尔/ Hardware_Accelerated_Execution_Manager / 打开IntelHAXM_1.1.0_below_10.10.dmg美元

显示模拟器窗口可能需要一到两分钟。

确保在SDK管理器上安装了HAXM安装程序。

下载后，确保运行位于: {SDK_FOLDER} \配件\ \ Hardware_Accelerated_Execution_Manager \ intelhaxm.exe英特尔

注意:在Android Studio中，命令“intelhaxm.exe”已更改为“intelhaxm-android.exe”

如果你在安装过程中得到“VT不支持”的错误，禁用windows功能上的Hyper-V。dism.exe /Online /Disable-Feature:Microsoft-Hyper-V。您还需要在BIOS中启用“虚拟化技术”
