Question

Hello I have trying to use LeaderBoards in android app.

____________________________EDIT________________________________________________

Ok, now I tried follow this link Guide

I create new project for test. I Have code like in Giude.

If want log-in was showed popup for Google Game download... OK, downloaded it.

BUT if I open app again app crashed. I don't know why. (I launch app in phone no, simulator)

Do you have some ideas? [I have new project with ONLY code from guide. + basegameUtils]

public class MainActivity extends Activity implements
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener, View.OnClickListener {

    private static int RC_SIGN_IN = 9001;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        try {

            findViewById(R.id.sign_in_button).setOnClickListener(this);
            findViewById(R.id.sign_out_button).setOnClickListener(this);


            // Create the Google Api Client with access to the Play Games services
            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addConnectionCallbacks(this)

                    .addApi(Games.API).addScope(Games.SCOPE_GAMES)
                    // add other APIs and scopes here as needed
                    .build();

        }catch (Exception e)

I find my mistake..

I was haven't this

<meta-data android:name="com.google.android.gms.games.APP_ID"
        android:value="@strings/app_id" />

in <application></application>

and it was a problem.
