BlackBerry Dynamics Launcher Library
The 
BlackBerry Dynamics Launcher
 is a user-friendly interface that allows users to easily access and switch between 
BlackBerry Dynamics
 apps, configure app settings, and take advantage of other useful features. For more information, see the BlackBerry Dynamics Launcher Framework documentation.
The 
BlackBerry Dynamics SDK
 and the 
BlackBerry Dynamics Launcher Library
 are mutually dependent. See the BlackBerry Dynamics SDK for Android Release Notes for the required version of the 
BlackBerry Dynamics Launcher Library
.
Restricted key prefix
The key prefix "blackberry" is reserved by 
BlackBerry
 and should not be used for key values, key attributes, or key elements. For more information and examples, see the Application Policies Definition in the appendix of the API Reference.
