Register device id directly with Amazon SNS

Question

I am using the Amazon Web Service to send push notifications directly to a device. After I install the app I get the device id, that I need to manually add to the Amazon SNS. I would like to know if there is anyway to register the device id directly with the amazon server the moment the user starts the application.

I have read this, but found it difficult to understand. Does anyone have any previous experience of how to do this?

EDIT 2 (What I have done so far)

I've followed the instructions from this link

1. I download the snspobilepush.zip file as instructed and extract and import the project into eclipse. I add the GCM project number, add the jar files and run the application. I get my device registration Id.

2. I open the Amazon SNS, add my device id and I publish a message. I receive the message on my mobile phone. Works great so far.

   MY PROBLEM

I would be having a lot of potential users for my application. So adding every device id manually to the SNS makes no sense. I need the Amazon SNS to directly register my device id when I start the app. Is there any option for me to do that? I couldn't find any definitive answer in the docs.
This link tells me to Use the "AWS Token Vending Service". However, I could not find any example of how to do that.

Using the AmazonSNSClient documented here:

http://docs.aws.amazon.com/AWSAndroidSDK/latest/javadoc/

it should be possible to register using code similar to this:

AWSCredentials awsCredentials = new BasicAWSCredentials("XXXXXX", XXXXXXXXXXXXXXX");
String platformApplicationArn = "arn:aws:sns:us-east-1:123456789:app/GCM/myappname";
AmazonSNSClient pushClient = new AmazonSNSClient(awsCredentials);

String customPushData = "my custom data";
CreatePlatformEndpointRequest platformEndpointRequest = new CreatePlatformEndpointRequest();
platformEndpointRequest.setCustomUserData(customPushData);
platformEndpointRequest.setToken(pushNotificationRegId);
platformEndpointRequest.setPlatformApplicationArn(platformApplicationArn);
CreatePlatformEndpointResult result = pushClient.createPlatformEndpoint(platformEndpointRequest);
Log.w(TAG, "Amazon Push reg result: " + result);

It was not liking my ARN, but that was a stupid typo that Reid pointed out and is now fixed above.
