- 56. The Flash Platform and HTML5 “HTML 5 and RIA platforms will be complementary technologies, and enterprise development shops will need to invest in both approaches to deliver expressive applications that combine reach and richness.”* -Forrester Adobe does and will continue to support HTML The Flash Platform has integrated seamlessly with HTML for 14 years, and that won’t change AIR 2.0 (desktop) includes support for HTML5 Adobe is committed to supporting HTML5 in its leading Web development tools The Flash Platform delivers cross-platform, cross-browser, cross-device consistency HTML5 implementations will differ and hinder content adoption of rich features, including video tag support No consistency in codec support for video is yet visible Adobe offers best-in-class tool chain used by 3.5 million designers and developers HTML5 will require and benefit from Adobe’s investment in breadth of tooling Rapid update cycles enable Flash innovations to reach ubiquity in less than 1 year Flash will continue to lead in innovation, much faster than HTML and browsers *“Does HTML 5 Herald The End Of RIA Plug-Ins? Not Really,” Forrester Research, Inc., April, 2010 All external content and images pending approvals.

- Adobe AIR is another runtime in the Flash Platform that has been extended to mobile platformsIn fact this year we intend to bring AIR to Android devices, and enable you to repackage these applications for the iPhoneWith Adobe AIR you can take advantage of more platform specific features, such as Geolocation and File access and distribute these applications through applications storesUltimately being able to monetize your applications is very important, and we believe that having the choice of browser or standalone distribution is hugely beneficial
- Delivering the new runtime for mobile phones requires a set of new features and investments.We have completed a huge amount of engineering to increase performance and use less memory on devices.As well as that, the new runtime supports features that are common on these new mobile platforms.We have added multi-touch support, Accelerometer, and new APIs for globalization, error handling and text input

- Today AIR enables developers and designers to create applications for Windows/Mac and Linux computersTo install applications we can use the .AIR package format for applications that can run across all platformsWith AIR 2.0 it’s also possible to use native code, and so we have enabled AIR applications to be packaged in .exe or .dmg files. Mobile devices will also use their native package formats, like apk for AndroidFor the most part these will require no extra effort for you, they merely ensure that you can distribute your applications in AppStores today.

- Mobile text input A virtual keyboard is automatically raised and lowered in response to focus changes on text fields when editing text on mobile devices supporting a virtual keyboard to enable unobstructed and intuitive text editing. The focused text field is centered in the visible region of the page and appropriately zoomed/scrolled to ensure it is not obscured by the virtual keyboard. Upon screen rotation, incoming calls, or other system events, any already existing text input is retained. The virtual keyboard works with TextField but does not currently work with the Text Layout Framework or other Flash Text Engine text.Multi-touch and gesturesCreate multi-touch aware content for a wide range of devices and multi-touch capable machines running Microsoft Windows 7. Interact with multiple objects simultaneously or work with native gestures, such as pinch, scroll, rotate, scale and two-finger tap. Multi-touch support in Flash Player 10.1 is not available for Android.Accelerometer inputA new Accelerometer class allows developers to read acceleration values in X, Y and Z axes from native device accelerometer sensors in ActionScript. Optimized SWF management for mobile(Mobile only)Flash Player 10.1 optimizes SWF loading and playback for mobile CPU and memory limitations to provide a better user experience. Instances are loaded or deferred based on SWF priority, visibility and available memory and CPU resources to enable more immediate browsing experiences without waiting for every SWF on a page to load. Developers can indicate SWF priority through a new HTML parameter, hasPriority. Deferred instances are loaded after the HTML page load is complete, and offscreen and invisible instances are started when they become visible. Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.Sleep mode(Mobile only)The Flash Player timer slows down when the mobile device goes into screen-saver or similar mode to reduce CPU and battery consumption on mobile devices. The timer returns to the default setting when a wake-up event is triggered. There is no interruption in audio/video playback. Incoming phone calls pause Flash Player.Graphics hardware acceleration(Mobile only)A GPU-based vector renderer replaces the software renderer on smartphones and other mobile devices, resulting in faster rendering performance for more expressive user experiences while consuming less power. Supports hardware acceleration of all rendering, including vector graphics, bitmaps, 3D effects, filters, color transforms, alpha, device and embedded text, Saffron type, and cacheAsBitmap. Implementation of graphics hardware acceleration will be dependent on the graphics silicon vendor of the device. This feature is not available for Android devices.H.264 video hardware decodingFlash Player 10.1 introduces hardware-based H.264 video decoding to deliver smooth, high quality video with minimal overhead across supported mobile devices and PCs. Using available hardware to decode video offloads tasks from the CPU, improving video playback performance, reducing system resource utilization, and preserving battery life. H.264 video hardware acceleration is not supported on the Nexus One at this time.
