Welcome to the Adobe Flex 4.5.1 SDK release.
Flex SDK includes the Flex framework (also known as the Flex class library), Flex command-line compilers, the Flex debugger, the ASDoc utility, and the debugger version of Adobe® Flash® Player and Adobe® AIR® runtimes. Use the Flex SDK to develop, compile, and deploy Flex applications that connect to XML and SOAP web services or connect to various server technologies such as PHP, Adobe® ColdFusion®, Java, and .NET using a server technology such as BlazeDS. Flex applications can be built and configured to target browsers via the Flash Player runtime and desktops or mobile devices via the AIR runtime.
This Flex 4.5.1 SDK build is 22.214.171.12428 and contains:
- AIR SDK 126.96.36.19920
- Flash Player 10.2.159.1
- TLF 188.8.131.52
- OSMF 184.108.40.20616
We strongly suggest you DO NOT overlay different AIR, AIR SDK or Flash Player versions into Flex 4.5.1 SDK build 220.127.116.1128. Development, debugging and deployment workflows are only certified with the AIR and Flash Player versions installed with the Flex SDK.
The Flex SDK installation is delivered as a ZIP file and contains the Flex framework, Adobe AIR framework, and command-line tools, such as the mxmlc command-line utility, Adobe AIR command-line utility, the ASDoc utility, the Flex command-line debugger, and the debugger version of Flash Player.
You should use Flex SDK with the latest version of the debug Flash Player 10. Prior to installing the Flex SDK, you should uninstall your current Flash Player.
Manual removal (for users who installed the plug-in via Install script):
- Delete the libflashplayer.so binary and the flashplayer.xpt file in directory /home/<user>/.mozilla/plugins/
Extract the Flex SDK ZIP file to this directory. The Flex SDK contains the following directories:
- /ant — Contains Flex Ant Tasks.
- /asdoc — Contains helper files for the ASDoc tool that creates HTML documentation from your MXML and ActionScript source code.
- /bin — Contains the mxmlc, compc, asdoc, and fdb utilities. The bin directory also contains the jvm.config file, which specifies Java settings that you can modify, if necessary.
- /frameworks — Contains compiled framework classes, configuration files, and framework source code.
- /lib — Contains JAR files used by the utilities.
- /runtimes — Contains installers for the Adobe AIR runtime inside the air directory and installers for debug versions of Flash Player 9 inside the player directory.
- /samples — Contains sample applications.
- /templates — Contains HTML templates for Flash Player detection and browser integration and inside the air folder, a sample Adobe AIR application.xml file.
There have been some changes made in Flex 4.5 SDK that alter certain behaviors compared to Flex 4. To get the full list of issues, please refer to the Flex Backwards Compatibility document. In most cases, you can maintain Flex 4 (or even Flex 3) behavior by using the compiler argument, -compatibility-version.
This section contains selected known issues and notable changes since the previous release. For a complete list of Flex issues and their status, see the public bugbase. The public bugbase lets you search for known issues, comment on them and add new bugs.

Text with Flex Mobile projects targeting Apple iOS
Editable text components should not be placed inside a Scroller. Focused text controls will not be clipped, which can cause the text to be overlayed on top of the ActionBar or TabBar. We recommend keeping editable text components on the top half of the screen or pushing a new screen for editing each individual item. Please see this tech note for more information.
Packaging applications for Apple iOS with Flex 4.5.1
Flex applications do not perform well on iOS when developed and packaged with Flex SDK 4.5.1 command-line tools. We recommend packaging applications for iOS using the AIR 2.7 command line packager (adt) - please see this tech note for more information.
SDK-30625 - RTE when re-orienting while SplashScreen is up
For a Flex Mobile project running in debug mode, the Application may throw a benign null-pointer RTE during a portion of the start-up application sequence if device orientation changes at that time. The RTE will bring up the standard Flash "uncaught exception" dialog if the application is running in ADL. The RTE may be noticed if running a debug session of the application either in ADL or on device. If encountered while debugging, the work around is to continue with the debugging session/dismiss the RTE. The RTE doesn't have an effect on the application and no work around is needed for release builds.
SDK-30277 - Xoom device briefly reorients itself to landscape during launch if an AIR application is launched in portrait orientation
Applications with autoOrients set to true that are launched on a Motorola XOOM, where the physical device orientation is portrait, may result in the application reorienting to landscape and back to portrait at launch.
