Research in Motion (RIM) unveiled its vision for the BlackBerry 10 platform at the BlackBerry World conference in Orlando, Florida and released the initial developer toolkit for native and HTML5 software development which is available in beta as a free download.
The toolkit includes the BlackBerry 10 Native SDK with Cascades, which allows developers to create graphically rich, high performance native applications in C/C++ using Qt. The Native SDK for BlackBerry 10 has a rich set of APIs (Application Programming Interfaces) that give developers access to core device features and a range of BlackBerry application services, such as Push and Payment services. Cascades is a powerful native application development toolset that allows developers to easily build visually stunning applications without having to write complex, low-level graphics code.
Applications created with any of the BlackBerry 10 tools will run on BlackBerry 10 smartphones as well as BlackBerry PlayBook tablets when the new platform becomes available for the PlayBook. All of the SDKs will be updated to give developers access to more of the BlackBerry 10 unique capabilities over the coming months.
