Key native SDK libraries
The BlackBerry 10 Native SDK provides a number of proprietary libraries, open source, and commercial third-party libraries to make app development easy.
In addition to the libraries that are available with the native SDK, there are a number of other libraries that you can install from BlackBerry GitHub to extend the capabilities of the native SDK for development. You can also create your own static and archive libraries. Static and archive libraries are useful for reusing functionality that you built.
Take a look at the Library support at a glance page for a list of libraries available for the BlackBerry 10 OS.
