One of the improvements promised for Android 2.2 ("Froyo") was Adobe Flash support. For simple Flash use in websites, especially Flash-based video, it seems to work well. Now Adobe AIR for Android has been released, along with the first wave of AIR-based demos and games. That sounds exciting for developers porting to Android from other platforms, but it's currently disappointing in practice.
To test the current Flash and AIR capabilities, I installed the latest update to Flash Player 10.1 on my HTC Incredible, along with Adobe AIR, an AIR demo, and three highly rated (in the Android Market) AIR-based apps: Meteor Storm, Jello Bounce, and PhysTest. I passed on the official Adobe Flash Showcase, which turned out to be little more than a bookmark to m.flash.com. Instead, I tested that site directly in the default Android 2.2 Web browser.
What I witnessed were slow responses to user interface actions, application crashes, and browser hangs. Not surprisingly given the performance and stability issues, these applications have been updated almost daily, so it's a good thing that the app authors report being able to ship them very quickly.
The simple AIR demo (AIRonAndroid Browser) demonstrates use of the phone's accelerometer, camera, GPS, multitouch, orientation, and keyboard events features. The initial version had numerous bugs and needed to be killed to get it to exit; today's update is more stable and responsive, but not exactly a speed demon.
