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
I had the same problem today. Additionally, the IDE posted an "Assertion Error" into its event log.
Downloading and reinstalling the preview version, then applying the patch to 0.2.6 worked for me.
Although this question is asked years ago. But now following simple solution worked for me.
Clicking 'Sync Project With Gradle files' makes all directories visible.
You have created a new gradle project not a new android project. Update your android studio tools to 0.2.3 - Go to Help menu - select check for update. then Update your android sdk tools, android support repository, android support library and android build tools using android sdk manager.
And update some configuration in project structure. Go to File menu->project structure -> in projects tab select Android SDK as default sdk and in SDKs tab set correct path to updated android sdk.
Now restart android studio and try to create a new project and it should work fine.
