title: Best way to send lots of events to server in android
body: <p>I want to send a lot of user events in Json format to my server for analytics purpose in android app. Sending so many events by firing a post retrofit method and waiting for a call back slows down the application. I am making calls asynchronously but still app is slowing down due to this. </p>
  
  <p>Is there a better way to send these requests? An optimized way I can send data. Maybe not even checking for callback response. Is it possible to do that with retrofit 2.0 or Okhttp. </p>
