Java 找不到类“android.app.Notification$Builder”

我收到一个错误，说明找不到类“android.app.Notification$Builder”，但我不确定为什么会突然发生这种情况，因为它以前是工作的

    String value = Values.get("name").toString();

    resultIntent.putExtra(field, value);

            getApplicationContext(), 0, resultIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);
    mBuilder.setContentIntent(resultPendingIntent);
    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    // mId allows you to update the notification later on.
    mNotification = mBuilder.getNotification();
    mNotification.flags |= Notification.FLAG_AUTO_CANCEL;
    mNotificationManager.notify(mId, mNotification);
    finish();

更改通知.Builder mbuilder=new Notification.Builder此为此NotificationCompat.Builder mbuilder=new NotificationCompat.Builder此我已尝试。。。现在我得到了：NotificationCompat无法解析为类型OK恢复到原始代码，清理项目并重建！，同时看看这是否对你有帮助！
