The note to be downloaded from peers concurrently.So I read about Executor service and I have used google-gauva for that, using callbacks to decide what to do on completion of task. I have doubt on how the design should be before proceeding forward. I have posted my query on the blog[1] . Could you please go through it and give feedback.
