在Android工作室中，AWS Rekognition检测标签错误

Question

当我实现这些代码时，会显示以下错误消息...

CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
            getApplicationContext.getApplicationContext(),
            "us-west-2:...",// Identity Pool ID
            Regions.US_WEST_2 // Region
    );

    AmazonRekognitionClient rekognitionClient = new AmazonRekognitionClient(credentialsProvider); <--Error Here

DetectLabelsRequest request = new DetectLabelsRequest()
            .withImage(new Image()
                    .withBytes(imageBytes))
            .withMaxLabels(10)
            .withMinConfidence(77F);

控制台消息：AmazonWebServiceClient：在区域元数据中找不到{cognito-identity，us-west-2}，尝试使用此区域的标准模式构建端点：'cognito-identity.us-west-2。 amazonaws.com”。
CognitoCachingCredentialsProvider：从SharedPreferences加载凭据 CognitoCachingCredentialsProvider：在SharedPreferences中找不到有效凭据
