如何在AWS SNS中一次订阅多个设备令牌

Question

我正在使用AWS SNS在Android和iOS设备中发送推送通知。任何人都可以告诉我如何同时订阅多个设备令牌（不是一个一个）。

我已经有一个设备令牌订阅的代码。

CreateTopicRequest createTopicRequest = new CreateTopicRequest("MyNewTopic");
    CreateTopicResult createTopicResult = snsClient.createTopic(createTopicRequest);

    //print TopicArn
    System.out.println(createTopicResult);
    //get request id for CreateTopicRequest from SNS metadata
    System.out.println("CreateTopicRequest - " +  snsClient.getCachedResponseMetadata(createTopicRequest));

    String topicArn = createTopicResult.getTopicArn()

    CreatePlatformApplicationResult platformApplicationResult
    String platformApplicationArn = ''

    long now = System.currentTimeMillis()
    println("----before-subscription-------" + now)

    platformTokens.each { String platformToken ->

        try {
            platformApplicationResult = createPlatformApplication(applicationName, platform, principal, credential);
        } catch (Exception e) {
            System.out.println("----------------" + e)
        }

        platformApplicationArn = platformApplicationResult.getPlatformApplicationArn();
        CreatePlatformEndpointResult platformEndpointResult = createPlatformEndpoint(platform, "CustomData - Useful to store endpoint specific data", platformToken, platformApplicationArn);

        String endpointArn = platformEndpointResult.getEndpointArn()
    // System.out.println("------------endpointArn--------------" + endpointArn);

      //subscribe to an SNS topic
        SubscribeRequest subRequest = new SubscribeRequest(topicArn, "application", endpointArn);
        snsClient.subscribe(subRequest);

逐个订阅会占用超过100个设备令牌的大量时间。所以请帮我解决我的问题。
