Google Calendar Api v3で403エラー

publicなGoogleカレンダーにアクセスして，Event一覧を取得する部分でApiからエラー返されます．

Google Calendarの公開APIのキーは発行しており，「許可対象Android アプリを編集」で，
keytool -list -printcert -jarfile ファイル名.apk の結果のSHA1とパッケージ名を指定しています．

この指定を外すと期待通りにレスポンスが返ってくることから，この指定でブロックされてしまっていると予測していますが，SHA1もパッケージ名の指定も間違っていない状況で403が出る原因が分かりません．

なにかヒントを頂きたくおもいます．よろしくお願いします．
