title: Use Xlint:deprecation with android
body: <p>So I almost always get some message like this when I'm compiling my android app:</p>
  
  <pre><code>[javac] Note: /home/kurtis/sandbox/udj/androidApp/src/org/klnusbaum/udj/PlaylistFragment.java uses or overrides a deprecated API.
  [javac] Note: Recompile with -Xlint:deprecation for details.
  </code></pre>
  
  <p>How do I recompile with this option? Do I have to edit something in my build.xml?</p>
