title: startActivity using android:name
body: <p>Manifest definition:</p>
  
  <pre><code> &lt;activity android:name="com.gannett.democratandchronicle.billstrainingcamp.PlayersActivity" /&gt;
  </code></pre>
  
  <p>WORKS:</p>
  
  <pre><code>startActivity(new Intent(this, PlayersActivity.class));
  </code></pre>
  
  <p>DOESN'T WORK: (No activity found)</p>
  
  <pre><code>startActivity(new Intent("com.gannett.democratandchronicle.billstrainingcamp.PlayersActivity"));
  </code></pre>
  
  <p>Why can't I use the full android:name to startActivity? Is the string parameter expecting something different?</p>
