Google now let you to run Android apps on your Chrome browser in your Computer with a tool called App Runtime of Chrome (ARC) Welder. It is a project which allows Android apps to run on Chrome OS.
Some time before this tool was only available for developers who got to collaborate with Google to do so. But now Google Officially launch its full version for Windows, Mac, Linux and Chrome OS which will allow you to run Android Apps on your Desktop. The all you need is just add APK files of application which your want to run on your PC. I also run WhatsApp on my PC with this tool and it works perfectly.
However, ARC isn’t run all Google Play Services, like Google+ etc and some apps that require missing services like in-app purchasing will fail to run or crash. Hopefully Google will add these in the near future to enable more apps to run on various desktop platforms.
