I am running latest version of Mac OS and I want to run android emulator through command line tool. I have run the following command on Mac terminal and got the following error.

 $ emulator -list-avds
Pixel_XL_API_28

 $ emulator -avd Pixel_XL_API_28
PANIC: Missing emulator engine program for 'x86' CPU.

I also run the command with available options like below that is also available on official documentation developer.android.com 

$ /Users/janedoe/Library/Android/sdk/emulator/emulator -avd Pixel_XL_API_28 -netdelay none -netspeed full

What I need to do, so that I don't need to open android studios every time for only opening simulator.

 Reload you .bash_profile Or .bashrc depending on OS

 Step 3 ( go to emulator directory )
 cd /Users/$(whoami)/Library/Android/sdk/emulator

  • Also ran into PANIC: Missing emulator engine program for 'x86' CPU. I had to specify the path to the kernel - see first answer here: https://stackoverflow.com/questions/51897046/mac-and-panic-missing-emulator-engine-program-for-arm-cpu – Casey L Jun 08 '20 at 00:32

Take a look here : Android Emulator Error Message: "PANIC: Missing emulator engine program for 'x86' CPUS."

Then go as follows by cmd :

(the path to your emulators) - C:\Users\user\AppData\Local\Android\Sdk\emulator>

(the emulator name) - emulator.exe @Nexus_5 -dns-server 8.8.8.8 -writable-system
