Android Studio 1.5 - How to display javadoc for google play services in AS

Question

Currently, I am using google play services for my project. Everything works fine, but if I open the javadoc for e.g. the GoogleApiClient it only displays the method signature and no further documentation.

It is possible to display those documentations in Android Studio 1.5 for e.g. google play services?

If so, what settings need to be done?

3. Click specify documentation URL
4. And specify an URL. For my machine it was file:///opt/android-sdk/extras/google/google_play_services/docs/reference or as @Benjamin suggested in the comments, add http://developer.android.com/reference/ as source, for online documentation lookup.
5. The result was:
6. And after a project sync I could browse the javadoc of the google play services
