How to run Android apps on Google Chrome

Google has released a new developer tool called App Runtime for Chrome (ARC) that allows Android apps to run on Chrome for Linux, Windows, and Mac.

Google Chrome's ARC app can now run any of your favorite Android apps like WhatsApp, Candy Crush, Viber, all from your Chrome web browser.
ARC operates via some special runtime implemented using Native Client (NaCl) technology.

Google ARC tool is based on Android 4.4, but there are some limitations:

you can load only one app at a time
you have to select portrait or landscape layout
you need to choose, whether you want the app to run on phone- or tablet-style.

How To Run:

Install the latest Google Chrome browser.
Download and run the ARC app from the Chrome Store.
Add third party APK file host.
After downloading APK app file to your PC, click Open.
Select the mode -> "Tablet" or "Phone"
Then click "Launch App".

I have personally tried this tool before writing, and some of my favorite Android apps work pretty well.
