Android devices running the new jelly bean OS seems can not support flash (happy to be corrected) and from the little I've read there is no way around it.
While I agree the world needs to ditch flash, the fact that so many sites still use it makes the lake of support disappointing. Basically Adobe and Google are forcing the world to replace all their flash content with HTML5. If only it were that simple ;)
So in the end, if you have a newer/updated android device we are stuffed until BB replaces all the flash with HTML5. So while not at the top of the list I think replacing flash content with HTML5 should be moving up the BB's "to-do" list as eventually it will start being a negative for users
