Android Studio stuck starting the emulator

I am new to Android development. I am stuck while writing an Hello World program.

Android Studio got stuck at the time of opening emulator.

OS - MacBook Pro

It stuck after showing below statements,

Waiting for device.
/Users/hiteshj/Downloads/android-sdk-macosx/tools/emulator -avd Nexus_5_API_19 -netspeed full -netdelay none

and, then it shows,

/Users/hiteshj/Downloads/android-sdk-macosx/tools/emulator -avd Nexus_5_API_19 -netspeed full -netdelay none
PANIC: Missing emulator engine program for 'x86' CPUS.

Some logs(emulator verbose in debug mode) related to above problem,

There is one more question I posted, but no help yet. question link.

From last 5 days, I was on the same step. Please help me to overcome from this problem.

As I can see your Android Studio is missing for 'x86' engines for your emulator. Please check these 2 points:

Verify that you have that system image installed. Open your SDK Manager and navigate to Android 4.4.2 folder. Install everything to be sure:
If it doesn't help, you also can try to change system image for your emulator. Create a new virtual device and this time choose anything except 'x86' if it still not working:
