三、常见问题

1、在运行app时提示未安装Intel HAXM错误信息：

Emulator: ERROR: x86 emulation currently requires hardware acceleration!

Please ensure Intel HAXM is properly installed and usable.

CPU acceleration status: HAX kernel module is not installed!

解决方案：

1) Open SDK Manager (In Android Studio, go to Tools > Android > SDK Manager) and Download Intel x86 Emulator Accelerator (HAXM installer) if you haven't.

2) 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. //需要重启电脑设置bios

3) Restart Android Studio and then try to start the AVD again.

It might take a minute or 2 to show the emulator window.

2、模拟器RAM过大，电脑内存不足，错误信息：

emulator: The memory needed by this VM exceeds the driver limit.

HAX is not working and emulator runs in emulation mode

在android studio 打开tools->android->avd manager 找到对应的avd 编辑，在弹出的配置文件点击'Show Advanced Setting' ,

在详细设置里面把滚动条拉下来（滚动条很不明显，是个坑），根据自己电脑内存分配下内存
