Trying to use the google-play-services_lib library but getting errors such as 'GooglePlayServicesClient not resolved to a type'

Question

What I have done

I'm working through these tutorials:

• developer.android.com/training/location/index.html
• developer.android.com/google/play-services/setup.html
• developer.android.com/tools/projects/projects-eclipse.html#ReferencingLibraryProject

and I guess where I am stuck is the 'Declaring library components in the manifest file' in the above page.

I'm guessing that this means that the library has not been imported correctly or that I am not declaring something. In fact, I would wager that it is my fault and I probably need to declare things in the manifest file or something. However, all my googling of 'declare activity googleplayservices manifest' leads me to believe that maybe there is nothing to declare for this library - otherwise surely I would have come across SOME kind of example?

sdk manager

Google play services are installed
Google apis are installed
There are no updates to be installed, so it can't be that there is anything out of date.

importing the library project

I have imported the library (right clicked on my project > properties > android > add > play services lib).
Tried with the 'is library' check box both ticked and unticked to no avail.

cleaning the project & library project

I have installed and used the project > clean function multiple times
Eclipse/ADT has been restarted multiple times

ERRORS:

(among others).

Thanks for the advice in advance. First post so I hope I have asked correctly and been clear.

Answer 1

I had the same issue with implementing GooglePlayServicesClient.ConnectionCallbacks as it couldn't resolve the import but simply removing the GooglePlayServicesClient. prefix and re-organising the imports corrected it.
