title: How does Log.wtf() differ from Log.e()?
body: <p>I have looked at <a href="http://developer.android.com/reference/android/util/Log.html" rel="noreferrer">the documentation for android.util.Log</a> and I'm not sure exactly what the difference between <code>Log.e()</code> and <code>Log.wtf()</code> is. Is one preferred over the other? Is there a functionality difference? Surely they aren't redundant.</p>
  
  <p><em>Note to future readers</em>: At the time this question was asked, the documentation for this was much less clear. If you follow the link above, they have fixed the problem.</p>
