title: android studio disable optimising imports automatically
body: <p>I had a few unused imports in Java file which were not used. Android Studio suggested me to "<strong>Optimize unused imports automatically on the fly</strong>" I clicked on it. </p>
  
  <p>Now all the unused imports are removed automatically. Is there a way to revert this settings?</p>
  
  <p>I am new to android so please forgive me if i missed something simple.</p>
