Hi,
The manifest you attached cannot be open, but if you added the android.includeGPlayServices= true correctly that meta data line should have been added to your manifest, if it's not there that property wasn't added properly.
How did you added that? using the build hints tab or directly to the properties? I assume directly to the properties.(if you open the properties manually it should look like this: "codename1.arg.android.includeGPlayServices=true")
