Developing Flash Lite 2.x and 3.0 Applications

Web content browsability

Flash Lite 3.0 supports the playback of most Flash 8 content on mobile devices with some loss of fidelity. Because of the high processor and memory requirements necessary to support features found in the Flash 8 Expressiveness feature set, many of these features are not supported in Flash Lite 3.0. These expressiveness features include bitmap caching, blend modes, bitmap filters, enhanced strokes, enhanced gradients, and 9-slice scaling. Whenever Flash Lite encounters any of these features in a SWF file, it renders these objects without the added expressiveness to maintain a usable mobile experience.

The following table describes the Flash 8 content and features that are supported, partially supported, or not supported.

Capability

Support

Details

Flash 8 basic HTML tags

Yes

The Flash Lite player can now recognize and play back most Flash 8 content, with some loss of fidelity.

Security enhancements

Yes

Flash Lite's security model is now consistent with the desktop player's security model. See Local file security for details.

Flash Video

Yes

The Flash Lite player now supports Flash Video (FLV) using versions of the On2 and Sorenson codecs optimized for mobile devices. Also supports RTMP client implementation (one-way, not two-way real-time). See Enhanced video capability for details.

HTML Base tag

Yes

Allows Flash Lite to behave in a manner similar to the Flash Player on the desktop.

FlashType text

Partially supported

Complete support is not critical to displaying content. Text is rendered, but without full FlashType implementation.

Bitmap caching, effects and enhancements

No

Not implemented because most require floating-point support or make excessive demands on processor or memory resources.

Focal gradients

No

Not implemented because they are processor-intensive and not critical to displaying content.
