我正在尝试将我的应用程序与 AWS Kinesis Video Stream 控制台连接。我将此 aws文档作为参考并尝试运行此官方示例应用程序。但是每次我尝试流式传输视频时，应用程序都会崩溃，但问题的根本原因在NotAuthorizedException哪里。Access to Identity 'us-east-1:xxxx' is forbidden这是 logcat 崩溃报告。

我也注意到在某种程度上Identity id与我在 logcat 中的不同。这是我的awsconfiguration.json：

{
  "Version": "1.0",
  "CredentialsProvider": {
    "CognitoIdentity": {
      "Default": {
        "PoolId": "us-east-1:5df15755-e58c-4c1c-bb86-f5bde7f0f446",
        "Region": "us-east-1"
      }
    }
  },
  "IdentityManager": {
    "Default": {}
  },
  "CognitoUserPool": {
    "Default": {
      "AppClientSecret": "qbhmasev6saq23st6t814i8ol8v1gibfbkn5isa5hsld2i121vm",
      "AppClientId": "a7pljsm5ru9gorqj6qq5onjrn",
      "PoolId": "us-east-1_WMzcnFp2P",
      "Region": "us-east-1"
    }
  }
}

我初始化 KVS 并引发异常的部分代码：

try {
    mKinesisVideoClient = KinesisVideoAndroidClientFactory.createKinesisVideoClient(
            getActivity(),
            KinesisVideoDemoApp.KINESIS_VIDEO_REGION,
            KinesisVideoDemoApp.getCredentialsProvider());
} catch (KinesisVideoException e) {
    Log.e(TAG, "Failed to create Kinesis Video client", e);
}

getCredentialsProvider():

public class KinesisVideoDemoApp extends Application {

    public static Regions KINESIS_VIDEO_REGION = Regions.US_EAST_1;

    public static AWSCredentialsProvider getCredentialsProvider() {
        return AWSMobileClient.getInstance();
    }
    ...
}

像往常一样，我尝试上网寻找解决方案。我以这个SlackOverFlow和这个Github作为参考，并尝试了所有可能的解决方案。我确保：

-> 我有权利user pool id，app client id在我的身份Authentication Provider Coginito部分。

-> 交叉验证注册用户列在用户池中。

-> 在设置中拥有正确的角色集UnAuth和Auth正确的策略identity pool。

-> 我还使用别名和密钥库注册了应用程序

没有什么对我真正有用。任何形式的帮助表示赞赏！谢谢！
