Blackberry application developers keep in mind the following principles while designing an app:

• The design should meet user needs

• Design should be based upon supported standards and supported content types

• Design should be in accordance with characteristics and features of mobile device

• Designing should consider wireless networks

Content design for users

The choice of content should be governed by the needs of intended users and this holds true for all apps including business and entertainment:

Understand who will lick upon the website, what are their needs and expectations and how to fulfill them with the website

The web pages should upload instantly and present feature-rich content. There need to be a clear understanding between the developer and the target users to present content and develop script behavior and where to commit design compromises.

Website needs appropriate hierarchy. BlackBerry app developers structure the website based upon its purpose and organize it to reduce the time users take to perform a task.

Minimal design enables efficient user-website interaction. The strategy adopted by mobile app developers involves reduction in number of links a user must follow and reduction in number of steps taken to view and work with content. This is done to maximize response from users.

The design layout should fit-in the mobile screen. Users should not scroll to either page-view or column-view. They should neither scroll horizontally nor rescale the content to read it.

Supported standards and content types

BlackBerry browser and standards and content types are improving and changing continuously. The best way to design the content is by deciding upon the target users and methods should be adopted to reach them. One essential thing to note is that blackberry browser was redefined in BlackBerry Device software Version 4.6. The design content should be in sync with user device to be used optimally by Smartphone users. Maximum users have running version of BlackBerry software device earlier than 4.6 and it is quite probable that these users will not change their handsets for few more years, meaning that they will not be able to make use of design content based upon browser.

A well designed content will make the BlackBerry app developer achieve excellent results on devices.

Design to characterize and feature device

Users might view and interact with content differently to make it adapt to different devices. Content should be adaptable to different devices. Content should support multi-screen resolutions and sizes and available input and navigation methods available on Blackberry. Test content on wide and narrow device screens and view it in portrait orientation.

The optimum way is to use style sheet and proportional rather than absolute measures.
