I am confused about the assets
folder. It doesn\'t come auto-created in Android Studio, and almost all the forums in which this is discussed talk about Eclipse.
When upgrading to the release version of Android Studio, you may be automatically switched to the new Android project View (see here for more info). If you swap back to either the Project or Packages view, you should see the standard folder hierarchy of a Gradle-based project. Then refer to CommonsWare's answer for the appropriate location.
