アプリの必要性Googleゲームがインストールされたアプリのクラッシュ時に再生

Question

こんにちは私はアンドロイドアプリでリーダーボードを使用しようとしています。 [OK]を____________________________EDIT________________________________________________

は、今私は、このリンクGuide

私はテストのための新しいプロジェクトを作成するに従ってみました。私はGiudeのようなコードを持っています。

Googleゲームダウンロードのログインが必要だった場合は... OKをダウンロードしてください。

でも、アプリをもう一度開くとアプリがクラッシュします。どうしてか分かりません。 （電話番号、シミュレータでアプリを起動します）

アイデアはありますか？ [私はガイドからのコードだけを使って新しいプロジェクトを持っています。 + basegameUtils]

私は私のミスを見つける。..

私は<application></application>

でこの
