title: Android transfer object data through different device, same app
body: <p>I want to implement a feature in an app where users can add friends and check and compare each other stats from the java objects created, which involves a few subclasses.</p>
  
  <p>I was wondering if anyone know what the best way to approach this would be? </p>
  
  <p>The only thing that pops out is using Firebase. Where the user would click a button to upload the data to Firebase with a UUID link, and then give the UUID to the other user, where he/she would have to manually type the UUID in a textfield, and it gets the data from Firebase.</p>
  
  <p>Would method be viable and is there any other better options? </p>
  
  <p>Thanks </p>
