Android Apps on the BlackBerry PlayBook
The new BlackBerry PlayBook OS 2.0 features an "Android Player" component that allows for access to a variety of popular mobile applications not previously available to RIM tablet owners. However, "official" Android apps for the PlayBook must be repackaged by their developers and then submitted to RIM for distribution via BlackBerry App World. Thanks to a handful of crafty developers and other PlayBook users, you can also "sideload" select Android apps that haven't made it to App World yet. Slide 2 outlines how to sideload Android apps, or go ahead and jump to slide 3 if you're already familiar with the process.
