AWS DynamoDB not work on Android but work on Unity Editor

[asahimx]

Expected Behavior

AWS DynamoDB SDK works on Unity

Current Behavior

I can save and get data to DynamoDB on Unity Editor .
When i build the app on Android device the LoadAsync and SaveAsync function is not run then i get this error on logcat:

ArgumentException: Object of type 'System.Object[]' cannot be converted to type 'UnityEngine.AndroidJavaObject[]'.

Then I do this thinks and try to build the app again

• Upgrade the AWS SDK to last version : aws-sdk-unity_3.3.618.0
• Upgrade the Unity to last version : 2019.2.10f1

The error is disappear on logcat, but the LoadAsync and SaveAsync function still not running , also the logcat not have any error.

Here is my code:

void Start()
    {
        
        UnityInitializer.AttachToGameObject(this.gameObject);
        AWSConfigs.HttpClient = AWSConfigs.HttpClientOption.UnityWebRequest;
        var credentials = new CognitoAWSCredentials("ap-southeast-1XXXX", RegionEndpoint.APSoutheast1);
        AmazonDynamoDBClient client = new AmazonDynamoDBClient(credentials, RegionEndpoint.APSoutheast1);
        var Context = new DynamoDBContext(client);
        

        Context.LoadAsync<DynamoDB>("UserId", (AmazonDynamoDBResult<DynamoDB> result) => {
             myTextView.text = "get"; //work on Unity Editor not work on Android
        }, null);
    }

Hi @asahimx, as noted in that issue you referenced, #1262, we are transitioning support of Unity from the aws-sdk-unity to our AWSSDK .NET Standard 2.0 dlls. Please try using those instead of the aws-sdk-unity package as we are not supporting fixes for this package anymore. Thanks for your understanding.
