Android デバイスから Google ストレージを使用したいと考えています。Google ストレージ サービスと Google ストレージ json API を有効にします。課金も有効にします。
次のコマンド ラインから SHA1 フィンガープリントを取得しました。
keytool -list -v -keystore ~/.android/debug.keystore
API コンソールで「SHA1 key;com.mydomain」を設定し、Simple API を取得しました。
バケットのコンテンツを取得しようとしていますが、次のエラーで立ち往生しています:

これは私のクラスです：

何かアドバイス ？
