Key Features of Mobile Development in Flex and Flash Builder 4.5

With the release of Flash Builder 4.5, you can now create Flex application development for Android, BlackBerry Tablet OS or iOS devices using the same workflow you use to build web or desktop applications today. The mobile development features in Flex and Flash Builder 4.5 provide several key features:

• Many of the core Flex components have been made mobile-ready, so when you use them in a mobile application, they automatically appear with skins and interactions optimized for small screens and touch input.
• Unlike web or desktop applications, mobile applications are typically structured around a series of simple views, as shown in the diagram above. Flex 4.5 provides View and View Navigator components to make it easy to build these types of applications.
• Flex provides mechanisms to make it easier for your application to adapt across screens with different pixel densities—a common problem in mobile development.
• The core Flex components have been optimized in order to perform well on devices with limited memory and CPU speed.
• Mobile applications built with Flex 4.5 use the AIR runtime, and are packaged using the native application format on each device, so they can be deployed and sold on application stores or markets the same way as native applications on each platform.
