Optimization overview
The limited processing power, number of colors, display area and memory of mobile phones requires optimization of Flash Lite applications designed or adapted for this platform. For example, applications must be designed to use memory and the limited CPU power efficiently and lead to small SWF file sizes.The Zip file included with this document contains a Flash file, with a movie clip which might be useful for monitoring the level of free memory and frame rates per second while testing an application during development.
The code can be copied and pasted into a Flash Lite project during development.
The optimization guidelines appendix presents advice, screenshots and code snippets in the following sections:
· Memory management
· Image rendering optimization
· Transparency
· Optimizing animations
· Placing objects on the screen
· Working with symbols
· Working with text
· ActionScript and some common pitfalls
· Limitations with regard to the display area
· Keeping content clean and tight
· Other optimization tips”

“Animation performance advice: keep the animation region small and not covering a large section of the phone’s screen.”
