Adobe has now ceased development on the Flash mobile browser plugin. Within a certain period of time, future versions of the Android and BlackBerry Playbook browsers may not be able to render Flash content, just like the iPhone and iPad.
In a blog post, Adobe said:
Our future work with Flash on mobile devices will be focused on enabling Flash developers to package native apps with Adobe AIR for all the major app stores. We will no longer continue to develop Flash Player in the browser to work with new mobile device configurations (chipset, browser, OS version, etc.) following the upcoming release of Flash Player 11.1 for Android and BlackBerry PlayBook. We will of course continue to provide critical bug fixes and security updates for existing device configurations. We will also allow our source code licensees to continue working on and release their own implementations.
They also said:
HTML5 is now universally supported on major mobile devices, in some cases exclusively. This makes HTML5 the best solution for creating and deploying content in the browser across mobile platforms. We are excited about this, and will continue our work with key players in the HTML community, including Google, Apple, Microsoft and RIM, to drive HTML5 innovation they can use to advance their mobile browsers.
