Building and Deploying Adobe Flex 3 Applications
Targeting Flash Player versions
You can use the target-player compiler option to specify the version of Flash Player that you want to target
with the application. Features requiring a later version of Flash Player are not compiled into the application.
Currently, this feature applies only to RSLs.
The command has the following syntax:
-target-player=player_version
The player_version parameter has the following format:
major_version.minor_version.revision
The major_version is required while minor_version and revision are optional. The minimum value is 9.0.0.
If you do not specify the
minor_version or revision, the compiler uses zero.
If you do not explicitly set the value of this option, the compiler uses the default from the flex-config.xml file. This
option is commented out in the default flex-config.xml configuration file.
This option is used with framework RSLs. It helps ensure that an application is compiled correctly. For example,
if you specify that your application should use a signed RSL but you do not specify a failover RSL, users of older
versions of Flash Player will not load a signed framework RSL and will therefore experience errors when they try
to run your application. If you don’t set the
target-player option or set it to some value less than 9.0.115, the
compiler throws a warning. You must be sure that your users request your application only with a recent version
of Flash Player. One way to do this is to include logic in your HTML wrapper that specifies a minimum required
version of Flash Player. For more information, see “Adding the Express Install script to the wrapper” on page 334.
If you do not specify a failover RSL, but set the
target-player option to some value greater than or equal to
9.0.115, the compiler will not throw a warning because players later than that version will load a signed framework
RSL and therefore do not generally need a failover RSL.
