Stephen WylieのGoogleドライブの例（here）を実装しようとしています。ここに私のコードは次のとおりです。ここでGoogleドライブSDKのアクティビティが見つかりません例外

は私のマニフェストです：ここでは

は私activity_main.xmlです：

そして、ここでは、私が受け取るLogCatエラーです。ボタンが押されたときに発生します。

誰でも手助けできますか？
ええ、私は同じことを聞いたことがあります - 残念なことです。しかたがない。コールドケースを開けていただきありがとうございます。 –
Googleの人々とのセッション中に、同じエラーが発生しました。彼らは私に言った... – Frank
これは、今はAPI 23エミュレータで私のために壊れています。 – powder366
