ionic cordova run android results in PANIC: Missing emulator engine program for 'x86' CPU

Question

After a great deal of searchings, I'm can't solve this error when I run:

ionc cordova run android -ls

OUTPUT:

ANDROID_HOME=/Users/lucianokrebs/Library/Android/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home
No target specified and no devices found, deploying to emulator        
No emulator specified, defaulting to Nexus_5_API_P

Waiting for emulator to start...

PANIC: Missing emulator engine program for 'x86' CPU.

And the emulator never starts

Also, when I run:

$ ${ANDROID_SDK_ROOT}/tools/emulator -avd my-custom-avd

I got: PANIC: Missing emulator engine program for 'x86' CPU.

But, when I run:

$ ${ANDROID_SDK_ROOT}/emulator/emulator -avd my-custom-avd

the emulator starts and works fine

Seems that the cordova set the wrong path when they try to starts the emulator. Someone already deal with that?

From SDK tools version 25.3.0 onwards, the emulator has been removed and moved to ../sdk/emulator.

Just set ${ANDROID_SDK_ROOT}/emulator to your $Path variable so that emulator can be called from the command line and ionic cordova will detect the emulator.
