title: Android: Real time android application design
body: <p>I'd like you to help me to choose the right technology that fits my requirements with least costs.</p>
  
  <p>The android app needs to constantly send the data back to server 
    (The data like heartbearts), as well as constantly receive the
    feedback data from server  (Real-time data, streaming)</p>
  
  <p>The data type can be number, text, or even graph.</p>
  
  <p>I'm now looking at three technologies</p>
  
  <ul>
  <li>MQTT</li>
  <li>stomp+orbited </li>
  <li>XAMPP</li>
  </ul>
  
  <p>I'm not familiar with any of that, please give your suggestions, thank you.</p>
