On defy / eclair 2.1 at the moment is supported :
-Flash lite in the browser and outside
-Flash 10.x support is introduced locally in android Froyo 2.2 and remotely through Skyfire even in android 2.1 in that case
I have installed the flash10 app for android 2.1 which is properly installed but useless because not supported by the browser.
Skyfire has launched v2.0 of its Android browser that brings with it a new “SkyBar” that gives you automatic Flash video streaming. The browser doesn’t actually play Flash natively, it goes through Skyfire’s servers which are then converted to formats that the mobile is happier to stream, such as HTML5.
