This is the focus controller. Use this controller to choose your primary development approach (Cascades or Core).
By selecting a focus, you get to decide what content should be front and center on the site.
Before you start developing, you'll need to visit the Downloads tab. Here you'll find downloads for the BlackBerry 10 Native SDK, BlackBerry 10 Device Simulator, and some other useful tools.
Now featuring a filter control, the Sample apps tab allows you to search for samples by name or by feature.
Select either the Core or Cascades check boxes to display the samples relevant to your focus.
The Documentation tab contains tons of examples, tutorials, and best practices to guide you along the path towards building an awesome app.
The documentation for your preferred focus always appears at the top of the left-hand navigation, but you can still access the rest of the documentation at the bottom.
The Reference tab is where you'll find essential details about how to use our APIs.
You can use the left-hand navigation to choose how you would like to browse the reference: by module, by topic, or alphabetically. If you have an idea of what you are looking for, start typing it in the Filter box.
