Java 尝试创建AmazonSClient时应用程序崩溃

我正在尝试创建AmazonSClient，并尝试列出平台应用程序列表，如下所示

AWSCredentials creds = new BasicAWSCredentials("XXXX", "XXXX");
try {
    AmazonSNS snsClient = AmazonSNSClient
                        .builder()
                        .withRegion(Regions.US_EAST_2)
                        .withCredentials(new AWSStaticCredentialsProvider(creds))
                        .build();

   ListPlatformApplicationsResult listResult = snsClient.listPlatformApplications(new ListPlatformApplicationsRequest());
   Log.d(TAG, "ADM : Platform Applications : " + listResult.toString());
}
catch(Exception err) {
    Log.d(TAG, "ADM : caught Exception while creating SNS client : " + err.toString());
}

我能够创建AWSCredentials，并且能够打印传递给BasicAWSCredentials的凭据。但当尝试创建AmazonSClient时，应用程序正在崩溃，甚至还没有到达catch块。我正在使用aws-java-sdk-1.11.646.jar。如果代码中有任何错误或如何修复此问题，请任何人帮助我
