Google Cloud Visionを使用しようとするとINVALID_ARGUMENTが表示される

Question

GoogleのクラウドビジョンAPIを使用して画像からテキストやラベルを検出したいだけです。しかし、私はこのコードを実行すると、私は常に取得：com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request

をしかし、私はなぜ知らない...ここで私は何を得るのフルJSON出力されます。

{ 
    "code": 400, 
    "errors": [ 
    { 
     "domain": "global", 
     "message": "Request Admission Denied.", 
     "reason": "badRequest" 
    } 
    ], 
    "message": "Request Admission Denied.", 
    "status": "INVALID_ARGUMENT" 
} 

は私のテストコードはここにある：

       message += "\n"; 
      } 
     } else { 
      message += "nothing"; 
     } 

     return message; 
    } 
} 

このコードで何が問題なのですか。
