首先，你必须在BIOS中启用Intel虚拟化技术:

第二，导航到您的SDK…\extras\intel\Hardware_Accelerated_Execution_Manager:

然后安装intelhaxm-android.exe。

注意，如果你在目录中找不到这个文件，请确保从SDK管理器中安装这个包:

对于那些使用基于Jetbrains的Android Studio的人来说:

Goto Tools > Android > SDK管理器 在Extras—>下选择Intel x86 Emulator accelerator复选框

对于那些不能使用Nexus AVD的人，也可以尝试使用Generic AVD。

Goto工具> Android > AVD经理

然后用QVGA之类的东西创建一个新的通用AVD，用于你的应用。这个AVD不使用硬件加速。

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。

While creating a Virtual Device select the ARM system Image. Others have suggested to install HAXM, but the truth is haxm wont work on amd platform or even if it does as android studio does not supports amd-vt on windows the end result will still be a very very slow emulator to run and operate. My recommendation would be to either use alternative emulator like Genymotion (works like a charm with Gapps installed) or switch to linux as then you will get the benefit of amd-vt and emulator will run a lot faster.

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。

我在这上面浪费了太多时间，之前的答案都没用。我发现Avast是问题所在!!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”

如果未安装intelhaxm-android.exe，请重新启动电脑安装。你可以在C:\Users\{YOUR USERNAME}\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager找到它
