title: Promises for Android?
body: <p>How do you face nested callbacks in Android? For example, in my app I use Locations API and then, when I have the current lat-lng, I do an HTTP request to my server. In this situation I have two nested callbacks. It's no so bad, but what If I had three or more? I've read about it <a href="https://stackoverflow.com/q/10695152/434171">in this question</a> but I wonder if there are something like Promises for Android.</p>
  
  <p>All I've found is <a href="https://github.com/CodeAndMagic/android-deferred-object" rel="noreferrer">this</a>. Someone knows more about the subject?</p>
