可以从异步任务中调用状态栏的通知吗

Question

我是 Android 编程新手，对 Java 不是很熟悉。

我在活动中加载带有 webview 的 url，然后调用 asynctask 来解析来自 url 的文本。解析后，我想将其发布到状态栏并发出通知。在 doInBackground 之后，我将解析后的字符串传递给onPostExecute，但出现编译器错误。

1. 不确定是否可以从以下位置调用 notificationcompat.builder onPostExecute 在 asynctask 中，或者如果需要从 活动。
2. 在 doInBackground 之后会自动调用 onPostExecute 吗？

谢谢，克雷格

protected void onPostExecute(String mycontent) {
// set up for notification in the notification status bar
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(getApplicationContext())

.setSmallIcon(R.drawable.ic_stat_notify_lightning)
                        .setContentTitle("My Title Here")
                        .setContentText(mycontent);


        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(this, WebViewActivity.class);

// The stack builder object will contain an artificial back stack for the
// started Activity.
// This ensures that navigating backward from the Activity leads out of
// your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(WebViewActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                        0,
                        PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);

        // Sets an ID for the notification
        int mNotificationId = 001;
// Gets an instance of the NotificationManager service
        NotificationManager mNotifyMgr =
                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
// Builds the notification and issues it.
        mNotifyMgr.notify(mNotificationId, mBuilder.build());
}

onPostExecute会在doInBackground之后在主线程上被自动调用，你能告诉编译器错误的更多细节吗？
