Anybody have a solution ?

Add this in yourbuild.gradle(app) inside dependency
compile 'com.google.android.gms:play-services:8.1.0'

[Solved]
I try to download new version of google-play-services library and import error is gone.
So, always update/download newest version of google-play-services library..

You need to add the dependency to your app.
Instructions for eclipse here
http://developer.android.com/google/play-services/setup.html
You can also do this by right clicking on your app (if you're using Android Studio) selecting Open Module Settings, going to the dependency tab. Then Clicking the "plus" at the lower left, select library dependency, then find play-services

android BaseGamesUtils library error

I'm trying to implement the google play services in my app. I have successfully imported BaseGameUtils library from GitHub, referenced the GooglePlayServicesLib to the library, but it has a really annoying error...
This is part of the GameHelper.java file :
import com.google.android.gms.appstate.AppStateManager;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.games.Games;
import com.google.android.gms.games.GamesActivityResultCodes;
import com.google.android.gms.games.multiplayer.Invitation;
import com.google.android.gms.games.multiplayer.Multiplayer;
import com.google.android.gms.games.multiplayer.turnbased.TurnBasedMatch;
import com.google.android.gms.games.request.GameRequest;
import com.google.android.gms.plus.Plus;
Everything is OK except the import com.google.android.gms.games.request.GameRequest; line which is underlined with the error message : com.google.android.gms.games.request cannot be resolved
I have no idea about how to solve this problem, and I see that the help community around google play games services is not as large as I would have bet...
any help would be welcome ! :)

I ran into the same problem. What fixed it for me was updating the google play-services library to a newer version.
Update the google play services library to the latest version. Thanks

google-api-java-client library not working in android

I am trying to use Google's places API. I downloaded google-api-java-client-1.6.0-beta.zip library and I'm using source code from https://github.com/tuthan/Google-Place-Api-Demo
I import the external library in exactly the correct way, but the code still give me compile time errors on all imports of google-api-java-client-1.6.0-beta.zip.
e.g.
import com.google.api.client.googleapis.GoogleHeaders;
import com.google.api.client.http.GenericUrl;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpRequestFactory;
import com.google.api.client.http.HttpRequestInitializer;
import com.google.api.client.http.HttpResponseException;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.apache.ApacheHttpTransport;
import com.google.api.client.http.json.JsonHttpParser;
import com.google.api.client.json.jackson.JacksonFactory;
I've been working on this for a week, but have been unable to solve it.

The dependency jars are not in your classpath. Please add the jar from google-api-java-client-1.6.0-beta.zip to your sample project.
