I'm using AWSSDK.KeyManagementService and AWSSDK.Core on a Xamarin-based project with Visual Studio 2015, and am trying to test it on my Android build (SDK 23). I installed the AWS stuff via NuGet and all is well there. This is my first time trying to use the AWS SDK.
When I attempt to use the KMS for something as simple as ListKeysAsync(), I get a dump of an Amazon.Runtime.Internal.HttpErrorResponseException. I'm am not using a proxy.
Here's the top-level exception:
ERROR|An exception of type HttpErrorResponseException was handled in ErrorHandler. --> Amazon.Runtime.Internal.HttpErrorResponseException: Exception of type 'Amazon.Runtime.Internal.HttpErrorResponseException' was thrown.

My gut is telling me that the unmarshalling error has to do with the Java Date/time string in x-amz-date" (20161227T234717Z), where there's a 'T' sandwiched between the date and time portions. The error says there is an invalid character 'T'.
I ran into a similar problem when unmarshalling a Java-created JSON request using Json.Net, and had to use my own custom converter for .Net's DateTime object.
I'm not sure if that unmarshalling error is tied to the first HTTP exception.
I'm new to the AWS SDK, and only need to use the KMS portions of the systems for the project I'm on.
When I imported the AWSSDK.Core and AWSSDK.KeyManagementService, it loaded some dependencies. Here's the list:
- AWSSDK.CognitoIdentity v3.3.0.0 - Runtime v4.0.30319 [Used only for testing]
- AWSSDK.Core v3.3.0.0 - Runtime v4.0.30319
- AWSSDK.KeyManagementService v3.3.0.0 - Runtime v4.0.30319
- AWSSDK.SecurityToken v3.3.0.0 - Runtime v4.0.30319
- PCLCrypto v1.0.0.0 Runtime v4.0.30319
- PCLStorage v1.0.2.0 - Runtime v4.0.30319
- PCLStorage.Abstractions v1.0.2.0 v4.0.30319
My Android project is built for SDK 23 (Marshmallow) with Visual Studio 2015 Update 3.
Here's the code I'm having problems with:
LoggingConfig _awsLogging = AWSConfigs.LoggingConfig;
_awsLogging.LogMetrics = true;
_awsLogging.LogResponses = ResponseLoggingOption.Always;
_awsLogging.LogMetricsFormat = LogMetricsFormatOption.JSON;
_awsLogging.LogTo = LoggingOptions.SystemDiagnostics;
AWSConfigs.AWSRegion = "us-east-1";
//AWSConfigs.CorrectForClockSkew = true;
// Used only for testing of Cognito [works]
CognitoAWSCredentials creds = new CognitoAWSCredentials( "<<identity pool ID>>",
RegionEndpoint.USEast1 );
// Create a new credential option using our Cognito
// identity pool for Plexus, using N. Virginia-1 region
AmazonKeyManagementServiceClient kmsClient =
new AmazonKeyManagementServiceClient( "<<access key>>",
"<<secret key>>",
RegionEndpoint.USEast1 );
kmsClient.Config.Validate(); // Validate configuration
ListKeysRequest request = new ListKeysRequest();
request.Limit = 20;
Task.Run( () =>
{
try
{
// This line returned without error
Task<ListKeysResponse> taskResponse = kmsClient.ListKeysAsync(request);
// This line of code throws an exception down in the SDK / mscorlib
taskResponse.Wait();
ListKeysResponse response = taskResponse.Result;
}
catch ( Exception ex )
{
DebugLog.Fatal(ex);
}
} );
I'm only using the Cognito stuff for testing. It's the ListKeysAsync() call I'm having problems with.
Does anybody have any ideas? There is no other AWS code anywhere else in my app - except for "using" statements. BTW, this code is invoked from the Application.OnStart() method if that is important.
Thank you in advance.
