This is really weird but personally I also encountered a lot of weirdness with the Android SDK, including classes that couldn't be found (but due to different reasons than in your case).
In situations like this I usually also clean the whole Eclipse workspace. Restart it with the command line parameter "-clean". You should also do that every time when Eclipse crashes because most of the time the workspace state / plugin configuration and temporary files get corrupted because of that. If that does not work you could try creating a whole new workspace. Import your project into it and try building it again. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
