RIM detailed this nicely for developers at BlackBerry 10 Jam but I think it is worth mentioning for the larger developer audience. Russell Andrade posted on the RIM DevBlog about two possible changes that BlackBerry Native SDK for Tablet OS developers may have to make to bring their apps to the BlackBerry 10 Native SDK. These changes are very minimal and one of them only applies to devs using the low level windowing framework in the NDK. Russell reiterated that one of RIM’s priorities has been to ensure that native SDK apps transition with minimal hassle to BlackBerry 10.
The two changes that may be necessary for developers are:
- Multi-Icon Support – This was necessary to support different screen sizes and allow developers to provide more than one icon size and splash screen depending on locale and resolution of the screen.
- Querying for Orientation – RIM has improved the process for developers querying which direction the device is currently rotated to. The old method is still supported on the PlayBook but you need to use the new method on BlackBerry 10.
