title: LeakCanary report leak in InputMethodManager
body: <p>I am trying to figure it out a leak in my app but I am not sure were this comes from.</p>
  
  <p>LeakCanary is telling me that I can ignore it. Is that right?</p>

  <p>There were several leaks caused by this fragment, but I fix them. This one I can't make it disappear.</p>
  
  <p>Any clue?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>One more thing, if I want to ignore it this should be enough?</p>
  
  <pre><code>.instanceField("android.view.inputmethod.InputMethodManager", "mCurRootView")
  </code></pre>
  
  <p>But is still showing up in LeakCanary</p>
  
  <p>Apparently this leak is in AndroidExcludeRef but still being reported.
