I downloaded the latest-and-greatest Windows SDK (android-sdk-windows-1.0_r2.zip) and installed it. I next ran the emulator and tried (once the emulator had booted) to run the Calendar app. All I get is "Sorry! The application Calendar (process com.android.calendar) has stopped unexpectedly. Please try again." All the other apps seem to work correctly - even the Browser.
Has anyone had success with the Calendar app? If so, what did you do differently? I need to get access to the Calendar API so I can begin programming to it.
