Estaba buscando en google, podría corregir algunos errores. Pero la aplicaciónsiempre se bloquea aquí:

logros.googleApiClient.connect ();

MainActivity (partes importantes):

Achievements achievements;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ...

    //Init Achievements
    achievements = new Achievements(this);
    achievements.googleApiClient.connect(); //**AppCrash**
}

@Override
protected void onStart() {
    super.onStart();
}

@Override
protected void onStop() {
    super.onStop();
    achievements.googleApiClient.disconnect();
}    

Achievements.java:

public class Achievements implements GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks{

public GoogleApiClient googleApiClient;
private Activity activity;

public Achievements(Activity activity){
    this.activity = activity;

    googleApiClient = new GoogleApiClient.Builder(activity)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Games.API)
            .addScope(Games.SCOPE_GAMES)
            .build();
}

private void signIn(GoogleApiClient signinClient) {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(signinClient);
    activity.startActivityForResult(signInIntent, 0);
}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    if(connectionResult.getErrorCode() == ConnectionResult.SIGN_IN_REQUIRED){
        signIn(Tools.getSigninClient(activity));
    }
    Toast.makeText(activity, connectionResult.getErrorMessage(), Toast.LENGTH_SHORT).show();
    Log.e(Const.LOGTAG, connectionResult.getErrorMessage());
}

@Override
public void onConnected(@Nullable Bundle bundle) {
    Log.i(Const.LOGTAG, "Play Service (Games) Connected");
}

@Override
public void onConnectionSuspended(int i) {

}
