sns push notification publish to a single device

This is the code i found on SNS's official site to publish to a topic

String msg = "My text published to SNS topic with email endpoint";
PublishRequest publishRequest = new PublishRequest(topicArn, msg);
PublishResult publishResult = snsClient.publish(publishRequest);
System.out.println("MessageId - " + publishResult.getMessageId());

I am developing a chat app on for android using sns(it will also push notifications to the existing ios counterpart of the app)

if i want to publish to a single device directly can i give device's "ApplicationEndPointArn" instead of topicArn

SNS is intended to decouple notification service from application layer.

We could create a topic and add mobile endpoints as subscribers.

When a message is published to the topic all subscribers will get notified.

Apart from this if you would really need single endpoint messaging you could try,

PublishRequest publishRequest = new PublishRequest();
publishRequest.setTargetArn(endpointArn);
publishRequest.setMessage("SOME MESSAGE");
snsClient.publish(publishRequest)

where endpointArn is a device endpoint.

But make sure that you persist this device endpoint when device is registered in SNS and use the same returned EndpointArn for further communication.
