title: Android: uses unchecked or unsafe operations
body: <p>I'm getting this message while building my project:</p>
  
  <blockquote>
    <p>...\listadapter\MyAdapter.java:  </p>
    
    <p>uses unchecked or unsafe operations. </p>
    
    <p>Recompile with -Xlint:unchecked for details.</p>
  </blockquote>
  
  <p>This happens for this lines of code:</p>
  
  <pre><code>@Override
      protected void publishResults(CharSequence constraint, FilterResults results) {
          beanList = (ArrayList&lt;Bean&gt;) results.values;
          notifyDataSetChanged();
      }
  </code></pre>
  
  <p>I have no clue what to do.</p>
