this issue is a bit similar to Cannot Create Android Virtual Device, the difference is that i am trying to create AVD on windows rather than ubuntu, one more difference is that i can create android 2.2 and 2.3 AVD without error, but failed to create ADV 4.x, why?
i have sdk and api installed for 4.x, anyhow.
