title: Intent to be fired when a call ends?
body: <p>I have an already built application and I want to add a feature that has to be started when a call ends.
  How can I achieve that?
  I thought that declaring in my <strong>manifest</strong> something like this</p>
  
  <pre><code>&lt;activity android:name="Filter"&gt;
      &lt;intent-filter&gt;
              &lt;category android:name="android.intent.SOMETHING" /&gt;
      &lt;/intent-filter&gt;
  &lt;/activity&gt;
  </code></pre>
  
  <p>could be enough, but what kind of <code>Intent</code> I have to put on the filter?</p>
  
  <p>Looking in the documentation I found only the intents that detects when a call is started.</p>
  
  <p>Is what I'm looking for possible?</p>
