The BlackBerry® Tablet OS SDK for Adobe® AIR® allows you to optimize your Adobe AIR applications for the BlackBerry® Tablet OS. This SDK provides APIs that extend Adobe® ActionScript® 3.0 and allow you to develop applications that have the look and feel of native BlackBerry® PlayBook™ tablet applications and take advantage of some of the unique features of the OS. These APIs provide some unique UI components and predefined skins and enable you to listen for events specific to the BlackBerry Tablet OS, such as a swipe down event from the top bezel (the touch-sensitive frame around the display area of the screen).

The BlackBerry Tablet OS supports the Adobe AIR 2.7 mobile device profile. The Adobe AIR 2.7 mobile profile was developed to provide the critical improvements in performance and reduction in processor usage that were necessary to bring Adobe® Flash® based applications to mobile devices such as smartphones and tablets. APIs have been added to ActionScript 3.0 to allow Flash applications to access some of the functionality that is unique to mobile devices, such as access to accelerometer and geolocation information and support for touch and gesture events.

The BlackBerry PlayBook tablet includes the Adobe AIR 2.7 runtime environment. Applications developed for this runtime should be fully functional on the BlackBerry PlayBook tablet with no additional development required, save for adjusting the application for the unique screen size of the tablet.

 qnx.dialog Contains the functionality used to create, manipulate, and position dialogs. Dialogs are used to prompt the user, to alert the user, and to enable you to perform tasks such as logging in to a system and changing your password.  
 qnx.display Contains classes that allow you to define the behavior and appearance of an application display window. This includes properties that define X and Y position, Z-order, alpha values and transparency, and focus behavior. This package also contains the Display class which allows you to interact with and configure internal and external displays. Contains the common API event functionality. This includes battery level and state events, media service connection events, image cache utility events, and application-related events (such as the low memory event).  
 qnx.locale Enables you to utilize locale-specific resources in order to provide a properly translated, multilingual user-experience for your application. Contains the classes that define low-level media player functionality.  
 qnx.system Encapsulates and exposes system, device, and application-specific properties. This includes battery status, PIN and software version information, and application-specific data.  
 qnx.ui.buttons Contains the functionality used to implement buttons.  
 qnx.ui.core Contains the functionality that enables you to position UI components on a view. The Container class is the "container" that is used to group and position interface components, while the UIComponent class is the base class for all components. Contains the classes that provide data for UI elements that implement the IDataViewer interface, such as lists. The DataProvider and SectionDataProvider provide data and methods that allow you to modify the data.  
 qnx.ui.display Contains the classes that govern the display. It contains classes that enable you to manipulate and view images. Contains event functionality for all user interface components. This includes specialized event types for each of the list classes as well as event classes for media controls, toggle switches and sliders.  
 qnx.ui.geom Contains the EdgeMetrics class that returns nine-slice scaling information about the scaled edges of a skin.  
 qnx.ui.listClasses Provides various list type functionality including basic list, tile list, section lists and drop down components. Provides user-interface functionality for the media player. This package provides classes for media player control and customization of media player interactions.  
 qnx.ui.picker Provides picker functionality for your application. The picker is a specialized list mechanism that allows you to select items from a set of scrolling cells. The picker is useful for displaying complex information and for allowing the user to select data from multiple scrolling columns, such as birth dates.  
 qnx.ui.progress Provides progress indicator functionality. The progress indicator provides temporal feedback during time-consuming or processor-intensive operations.  
 qnx.ui.skins Contains basic component skin implementations. The skins classes provide a customizable, consistent, look and feel for the SDK component set.  
 qnx.ui.skins.buttons Contains skin implementations for all button components.  
 qnx.ui.skins.listClasses Contains skin implementations for all list components.
