I have created a new project using the latest version of Android Studio (0.2.2), this is a fresh install of studio. When I am in the project explorer view, it fails to show me any folders for my project. I should see a root project folder, and within it the .idea, gradle, and module folders, but they are not showing.
Here is what I expect to see (taken from the sample project created on first boot):

But here is what I see immediately after the project's creation:

I cannot figure out how to expose my project's folders! I do not want to develop without the project explorer, it's simply too much of a hassle. Did I create the project incorrectly, or am I missing some not-so-obvious setting somewhere?
Thanks.

并更新项目结构中的一些配置。转到文件菜单-> 项目结构-> 在项目选项卡中选择 Android SDK 作为默认 sdk,并在 SDKs 选项卡中设置更新的 android sdk 的正确路径。
