Google made more than one play to one-up Apple with yesterday's unveiling of Android 2.2 (a.k.a. Froyo). As developers got beyond the major additions (i.e. Flash support, tethering, Wi-Fi hot spot capabilities), they were also treated to more subtle but nonetheless impressive demos of upcoming functionality like over-the-air (OTA) app installation and streaming iTunes support.

According to Endgadget, Google demonstrated OTA application installation during a presentation yesterday. The feature would allows users to find an app on their desktop, push it to their phone and install it with one click, in much the same way Apple's App Store works.

iTunes streaming to Android phones may sound a little strange, but it's actually made possible by Google's acquisition of a company called Simplify Media. Simplify started out making an app for the iPhone, which allows iPhone users to stream their desktop iTunes libraries directly to their phones from anywhere. The app is no longer available at the App Store, as its technology has apparently migrated to Android.

There's sure to be more surprises as developers dig deeper into the Froyo SDK. To be sure, Google has set the stage for a showdown as Apple gears up for its annual developer conference next month.
