在doInBackground（）方法中触发状态栏通知？

Question

我收到了应用用户的以下报告：

class java.lang.RuntimeException
Msg: android.os.AsyncTask$3.done:200 (An error occured while executing doInBackground())

我唯一能做的就是导致错误，试图在遇到错误时触发状态栏通知。我可以在doInBackground()方法中执行此操作，还是只能在onPostExecute()方法中执行此操作？

这里有一些代码......

在我的doInBackground()方法中，我在catch块的try/catch部分调用了以下函数：

private void triggerNotification(String contentText) {
            mNotificationManager = (NotificationManager) thisContext.getSystemService(ns);
            if(contentText == null) {
                contentText = "Sync complete.";
            }
            Intent notificationIntent = new Intent(thisContext, SomeOtherClass.class);
            PendingIntent contentIntent = PendingIntent.getActivity(thisContext, 0, notificationIntent, 0);
            notification.defaults |= Notification.DEFAULT_SOUND;
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            notification.setLatestEventInfo(thisContext, tickerText, contentText, contentIntent);
            mNotificationManager.notify(NOTIFICATION_ID, notification);
    }
