title: Calling startActivity() from outside of an Activity?
body: <p>I'm using an <code>AlarmManager</code> to trigger an intent that broadcasts a signal. The following is my code:</p>
  
  <pre><code>AlarmManager mgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
  Intent i = new Intent(this, Wakeup.class);
  try
  {
      PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, 0);
      Long elapsed +=  // sleep time;
      mgr.set(AlarmManager.RTC_WAKEUP, elapsed, pi);
  }
  catch(Exception r)
  {
      Log.v(TAG, "RunTimeException: " + r);
  }
  </code></pre>
  
  <p>I'm calling this code from an <code>Activity</code>, so I don't know how I could be getting the following error...</p>
  
  <pre><code>ERROR/AndroidRuntime(7557): java.lang.RuntimeException: Unable to start receiver com.wcc.Wakeup: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
  </code></pre>
