Unfortunately Android doesnt yet have flash support on its phones by OS default, but weve been assured over and over again that it is coming. While Apple disregards Flash on the iPad in favor of HTML5 (and to spite Adobe), the jury is still out and will be for some time on which is more efficient for rendering animation. Michael Chaize highlighted a test designed to determine which is currently faster on Android Flash or HTML5 by running some simple benchmarking animations on his Nexus One: At about 2 minutes and 20 seconds in, you can clearly see that Flash is the victor, rendering animated balls with shadows MUCH more quickly and smoothly than HTML5 with both running on the Nexus One. Furthermore, when testing the animation with Flash 10.1 on the Nexus One he gets 20fps, while Safari only runs the animation at 1-2fps on the iPhone 3GS with HTML5.
