posted a changelist
of new features brought forth by the latest Google Glass
APK (XE7), and they include expanded capabilities for the “OK, Glass” functionality, increased web browsing controls, the ability to call or send a message to anyone in your Google contacts, more refined voice search tools, and more.
user zhuowei posted some additional “hidden” changes in XE7 that he found by digging through the code. The most interesting bit is called “Boutique”, which appears to be the beginnings of an application market.
Google Glass "OK Glass" functions
He notes that there’s currently no central repository for Google Glass apps and said, “It seems that Boutique will fix this problem, by allowing Glassware and APKs to sync down to the Glass. There's code to sync the installed list of Glassware and to send currently installed native APKs.”
Google Glass web browsing
If he’s further correct that a native SDK is forthcoming, that would make developing apps for the spectacles much easier, too.
