I found a youtube tutorial for running Android apps in Chrome in Windows with ARC Welder. It will also work for Chrome for Mac and Linux.

You need the APK of the app that you would like to launch in order for it to work because right now android apps available on the Chrome Web Store from the browser are only searchable and installed on a ChromeBook.

Simple APK files will work, but those built with NDK for other architectures like ARM will not. Those that uses Google Play Services will likely not work either. I tried an app that uses Google Play Services. It asks me to install Google Play Services but when I click on “Get Google Play Services” nothing happens.

So far I have tested Evernote, Twitter and Pandora and they work pretty smooth. Pandora actually plays music really well without any issues.
