如何设置 AWS SNS 以向 Android 设备列表发送推送通知

Question

I have followed the documentation of AWS SNS push notification. http://docs.aws.amazon.com/sns/latest/dg/sns-dg.pdf

I have successfully send Push notification to android device via GCM, But I am sending only one android device at a time. (To sending multiple devices I have to run the same code again and again via for loop)

So my question is : Is there any way to send push notification for multiple android device at the same time. (Means is there any API, any method who took multiple device token (registration id) as a List or Array and send the push notification to all Android device)

Thanks

Subscribe the devices via the SNS client to a topic and then publish your message to the topic. All devices subscribed to this topic will receive the notification.

Subscribing to a topic:

String subscriptionId = snsClient.subscribe(new SubscribeRequest()
            .withEndpoint(endpointId)
            .withProtocol("application")
            .withTopicArn(topicId)
            ).getSubscriptionArn();     

Publish notification in a topic:

PublishResult result = snsClient.publish(topicArn, message);
