title: What does the language level setting in android studio 0.3.2 Do?
body: <p>In the latest release of Android Studio (0.4.2), a new setting has been added when creating a new project, namely <a href="http://tools.android.com/recent/androidstudio032released" rel="nofollow">Language Level</a>
  I want to know what that refers to, and the consequence of selecting any of the provided options.
  The doc doesn't give me a clear picture of this and i don't want to select an option when i don't know what that will result in?
  Thanks</p>
