Best Practices for Performance and Memory for Flash Lite

Adobe Flash Lite online live seminar: Best Practices for Performance and Memory for Flash Lite and Developer Center article.

Some takeaways:

1. Help the garbage collector by explicitly deleting objects (e.g. XML) and setting local objects to null. It's unclear how setting local objects helps because the reference count should go to zero once it's out of scope.
   
2. fscommand2("GetFreePlayerMemory") returns the size of the largest contiguous block of memory that can be allocated by the player, not total free memory.

Flash Lite Memory Size

Total available memory allocated by Flash Lite player, using
fscommand2("GetTotalPlayerMemory");

Cookie Support in Flash Lite Players

Cookie support in standalone Flash Lite players varies by platform. For Flash Lite content accessed through a web browser, cookie support will be provided by the web browser.

Here is a partial list of the platforms I've tested. I'll update them based on feedback and as I get access to more platforms.

Cookie support:

• FL 2.1 player on Windows Mobile

No cookie support:

• FL 2.0 player on Nokia S60 FP3 (N95)
• FL emulator (Adobe Device Central)
