这个问题通常出现在使用AWS Kinesis Video Stream时，无法获取作为AWS资源的授权身份验证信息。通常，这是因为没有正确配置AWS身份验证信息所导致的。

要解决这个问题，您需要确保正确地配置AWS身份验证信息。在欲访问Kinesis Video Stream资源的Activity中，您可以使用以下代码示例确保配置了正确的身份验证信息：

import com.amazonaws.auth.CognitoCachingCredentialsProvider;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.kinesisvideo.AmazonKinesisVideo;
import com.amazonaws.services.kinesisvideo.AmazonKinesisVideoClient;
import com.amazonaws.services.kinesisvideo.AmazonKinesisVideoClientBuilder;
import com.amazonaws.services.kinesisvideo.AmazonKinesisVideoRuntime;

// Configure credentials
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
    getApplicationContext(),
    "your_identity_pool_id",
    Regions.US_EAST_1
);

// Configure client
AmazonKinesisVideo kinesisVideoClient = AmazonKinesisVideoClientBuilder.standard()
    .withCredentials(credentialsProvider)
    .withRegion(Regions.US_EAST_1)
    .build();

// Create an instance of the runtime
AmazonKinesisVideoRuntime kinesisVideoRuntime = AmazonKinesisVideoRuntimeFactory.createKinesisVideoRuntime(
    getApplicationContext(),
    Regions.US_EAST_1.getName(),
    credentialsProvider
);

// Use the client or runtime as necessary

请确保将“your_identity_pool_id”替换为您的AWS身份池ID。这样，您就应该能够成功获取所需的身份验证信息，顺利访问AWS Kinesis Video Stream。
