PubNub Publish Sync

If you can wait a week or two for v4.0 of the PubNub SDK, it is super simple to do sync publishing. It is currently in beta2 but no changes are planned before GA in the next week.

pubNub.publish().message(Arrays.asList({'msg':'hello', 'sender':'user123'})).channel("my_channel").sync();

Yes. Please refer to PubNub publish not working post that has the complete code showing how you can make a synchronous publish with PubNub 4.0 SDK version.
