While you're undoubtedly aware that the PlayBook will gain the ability to run Android apps at some point, RIM's come clean with specifics as to which ones will run on the biggest BlackBerry. According to Thinq, engineers from the Canuck company confirmed that the upcoming compatibility layer will not support apps written with the NDK -- you know, wares written in C instead of the typical one-two Java / Dalvik punch. Also on the chopping block are those that incorporate Google Maps, in-app billing or Mountain View's text-to-speech engine. Similarly, live wallpaper and applications that use VoIP or have more than one activity linked to the launcher are also on the outs. It's been decreed then: don't expect a fantastical bevy of apps to make the jump sans elbow grease, which if we're honest, is about right given the other news out of Waterloo.
