title: Can we use Optionals in Android programming?
body: <p>I have been reading about the Optional type in Java 8. I want to implement in some of my Android code.</p>
  
  <p>But does the Dalvik machine for the latest versions of Android (5.1 and 6) implement everything in Java 8?</p>
  
  <p>I'm still running Java 7 with the Eclipse and Android Studio installed on my computers.</p>
