title: SecurityException: Permission Denial requires null
body: <p>I would like to launch the market from a preference screen but when I try to do this I obain a java.lang.SecurityException: Permission Denial: starting Intent { cmp=com.action.test/.ui.activities.Test } from ProcessRecord{44db1300 3697:com.pippo.pluto/10067} (pid=3697, uid=10067) requires null.
  This is my code: </p>
  
  <pre><code>startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse("market://search?q=pname:com.action.test")));
  </code></pre>
  
  <p>what am I doing wrong?</p>
