android - AWS Facial Rekognition 尝试在 Android 应用程序中使用 BasicAWSCredentials 描述集合

问题描述

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。现在我做了一个非常简单的示例应用程序，所以我可以在 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。但是我遇到了一个错误，我没有看到任何错误。我在 AndroidManifest.xml 中允许 Internet 连接，并且具有 accesKey en 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“DoeIets.java”类

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。
