　　如果出现如下问题说明Intel x86 Emulator Accelerator (HAXM Installer) 没有被安装。

运行android skd 打开sdk manager, 安装 Intel x86 Emulator Accelerator (HAXM Installer) 直至 installed 状态。

这时回到命令行

到 android-sdk-macosx/extras/intel/Hardware_Accelerated_Execution_Manager目录下 执行 

./silent_install.sh

　　再次执行 

ionic emulate android

　　就不会出现问题了
