App brauche Google Games Play, wenn installierte App abgestürzt ist

Question

Hallo Ich habe versucht, LeaderBoards in Android-App zu verwenden.

____________________________EDIT________________________________________________

Ok, jetzt habe ich versucht, folgen Sie diesem Link Guide

Ich erstelle neues Projekt für Test. Ich habe Code wie in Giude.

Wenn Sie Login Popup für Google Game Download angezeigt wurde ... OK, heruntergeladen.

ABER wenn ich App wieder öffnen app abgestürzt. Ich weiß nicht warum. (Ich starte App in Telefon Nein, Simulator)

Haben Sie einige Ideen? [Ich habe ein neues Projekt mit ONLY-Code von Guide. + BaseGameUtils]

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