Support for Sencha Touch on the BlackBerry Application Platform

Sencha Touch 2.1 is supported on devices that run the BlackBerry 10 OS . The 2.1 version addresses some of the performance-related issues that might have affected BlackBerry apps that were built using the 2.0 version and had complex nested layouts.

The performance improvements in Sencha Touch 2.1 result from changes to the DOM structure and additional CSS rules to help the browser render complex layouts better, without making any changes to the APIs. If you built your app using Sencha Touch 2.0 and used custom CSS, consider reviewing those CSS selectors if you are updating your app to Sencha Touch 2.1.

Applying the BlackBerry theme

Sencha Touch can detect a mobile device platform automatically and loads the appropriate theme. Sencha Touch 2.1 contains a predefined theme for the BlackBerry 10 OS, so it lets you automatically apply a look and feel to your apps that is native to the BlackBerry 10 OS, in addition to applying your own styles. You can download the beta theme for BlackBerry 10 from the following webpage: http://www.sencha.com/blog/introducing-sencha-touch-2-1-and-more/
