Android has supported it since v 2.2 (at least 3 years since HTC Hero), and I've used it on Samsung, Motorola and HTC devices. Blackberries also have a deep implementation of AIR.
Are there actually any higher-end phones or tablets made by anyone other than Apple that don't support flash? I'm genuinely curious since I love to play on kongregate.com during commutes.
Actually, the player hasn't been discontinued at all. It's still supported and bugfixes are still released. The decision was not to develop new versions in the future and instead to focus on flash apps via AIR. As of now, Android and Blackberry both support the newest version-- version 11, with 3D hardware acceleration.
In a generation or two, flash may indeed be "legacy" for mobile browser clients. That has absolutely nothing to do with the rest of the web market or the "mobile in general doesn't support flash" claim, which is verifiably false.
The very definition of discontinued is no new versions. Bug fixes and support don't change that.
As the majority of mobile devices in users' hands today do not support Flash, it is indeed fair to say "mobile in general doesn't support Flash". Again, that's the definition of "in general".
