Join David Gassner for an in-depth discussion in this video Laying out an application for multiple devices, part of Flash Builder 4.5 and Flex 4.5 New Features.
When you first get started building mobile applications with Flex 4.5 and Flash Builder, …you will probably design your application for a single mobile device.…It might be an actual physical device that you have or you might be using one of…the emulator settings that Flash Builder provides.…Flash Builder has many available configurations for mobile device testing.…To see these go to the Preferences dialog.…On Mac go to Flash Builder > Preferences and on Windows go to the Window menu…and then Preferences.…Then in the Preferences dialog, choose Flash Builder and then…Device Configurations.…
You'll see many preconfigured devices in this list.…You can add your own device if you like.…New devices are being introduced by vendors constantly and so if you want to…test for a new device, you can add its name, its platform, either Apple or…Android, and then its width, height, and other settings.…For this exercise I am going to be working with two settings, for the Droid…Pro and the Droid 2.…So far I've been testing this application using the screen size and other…

Q: Is Flash Builder compatible with Mac OS X 10.7 (Lion)?
Q: I'm using the most recent versions of Flash Builder and Flex. The projects provided in this course's exercise files don't run correctly. How do I get the code working?
A: The course's exercise files were built for the original release of Flash Builder and Flex 4.5. There are two potential issues: the version of the Flex SDK linked into each project and the version of Flash Player you have installed on your system.
For each project, follow these steps after importing it into Flash Builder:
- In the Package Explorer view, right-click on the project name and choose Properties.
- Click Flex Compiler.
- Change the Flex SDK Version to Use default SDK.
- Click OK.
- The project should now compile correctly.
- Open Windows Explorer (Windows) or Finder (Mac).
- Navigate to the Flash Player installation folder.
- Open the player subfolder.
- Open the subfolder for your operating system (Mac or Windows).
- Open the version subfolder.
- If running on Mac, open the DMG file and install the Flash Player application.
- If running on Windows, run the Flash Player installer executable for whichever browser you use for previewing Flex applications.
