Apparently Google offers "developer workflows" to package the Chrome apps.
You can run your Chrome app on a device or emulator using the command-line or an IDE, and you can also use the Chrome Apps Developer Tool to run your app on an Android device without the need to install the mobile platform’s SDK or an IDE.
The news is not completely a surprise since users can now launch Chrome apps from the desktop of their Windows Machine or Mac. It's also a typical move from the search giant. Google often releases redundant or competing products (think Wave, G+, G Talk, Hangouts) or "test" concepts in the open. Though, Chrome is clearly more than a test at this point. Chrome apps allow the user to create, store, and access information in the cloud very easily and on any platform. The only question is whether having both Chrome and Android will create confusion for the user and whether or not they will begin to compete with one another. Some apps are available on Android and Chrome. Is there a use case for having both?
In some ways Chrome seems like a trojan horse and is specifically targeted at iOS. Another point of consideration is the potential security risks. If Chrome apps are given greater access to the computer hardware (thereby emulating native apps) then this could be yet another point of exploitation for malware. Another possibility is that Google plans to continue to develop Chrome into a full fledged OS and having it available on a variety of platforms will familiarize people with the concept and brand, therefore making it easier to convince customers to switch from OSX or Windows to Chrome OS.
Chrome is certainly not something to underestimate, and its evolution continues to surprise even its most enthusiastic patriots.
