AWS面部识别试图用Android应用程序中的BasicAWSCredentials描述集合。]

Posted 2021-04-12

[我正在尝试制作一个无需使用S3，Cognito或Amplify框架即可与AWS Facial Rekognition连接的android应用程序。我想在应用程序中对我的accessKey和secretKey进行硬编码。现在，我制作了一个非常简单的示例应用程序，因此我可以在Android Studio中测试Rekognition的功能（这是主要目的）。

当我按下按钮时，我正在调用“ DoIets”类的对象。但是我遇到了错误，并且没有发现任何错误。我允许在AndroidManifest.xml中进行互联网连接，并且具有accesKey和secretKey的用户具有AmazonRekognitionFullAccess策略。在gradle文件中，我导入了'com.amazonaws：aws-android-sdk-core：2.10。+'和'com.amazonaws：aws-android-sdk-rekognition：2.10.0'。

这是类“ DoeIets.java”

import android.util.Log;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.rekognition.AmazonRekognition;
import com.amazonaws.services.rekognition.AmazonRekognitionClient;
import com.amazonaws.services.rekognition.model.DescribeCollectionRequest;
import com.amazonaws.services.rekognition.model.DescribeCollectionResult;

public class DoIets {

public void main() {
    Log.w("Test", "In DoIets Class");

    String collectionId = "MyCollectionName";
    AWSCredentials credentials = new BasicAWSCredentials("MYACCESKEY", "MYSECRETKEY");
    AmazonRekognition rekognitionClient = new AmazonRekognitionClient(credentials);
    rekognitionClient.setRegion(Region.getRegion(Regions.EU_CENTRAL_1));

    DescribeCollectionRequest request = new DescribeCollectionRequest().withCollectionId(collectionId);
    DescribeCollectionResult describeCollectionResult = rekognitionClient.describeCollection(request);

    Log.w("Test", "Face count" + describeCollectionResult.getFaceCount());
}
}
我得到的错误如下。
