Android and Java apps will run on the PlayBook via two optional "app players", which make it easy for users to download the apps from BlackBerry App World.
According to RIM, developers will be able to port their apps to the BlackBerry Tablet OS with ease. For now, RIM said that only Android 2.3 applications will be compatible with the OS.
The Canadian company also announced support for cross-platform game engines from Ideaworks Labs and Unity Technologies - which means the PlayBook will get AirPlay and Unity 3 games.
The app players for BlackBerry Java and Android applications will be demoed by RIM at BlackBerry World in Orlando, Florida, between May 3 and May 5.
