服務完成后在狀態欄上發送通知

Question

我有一個正在使用服務下載圖像的應用程序，但是我希望在下載完成后通知用戶，即使用戶不在該應用程序之外（狀態欄中的通知），該應用程序也可以在minSdkVersion =“ 8”中使用，我知道對此有一些答案，但是我沒有得到通知的工作：這是我的一些代碼（僅通知有問題，它可以工作）：

public class saveJsonContact1Service extends IntentService {

    private static FileOutputStream fos;

    private int result = Activity.RESULT_CANCELED;

    public saveJsonContact1Service() {
        super("saveJsonContact1Service");
      }

    @Override
      protected void onHandleIntent(Intent intent) {

        downloadImages();//To download images


        sendNotification();//To send a notification after the donwloadImages() method has ended

      }


      private void sendNotification(){

          CharSequence sns = "content";
          CharSequence sns2 = "content";

          NotificationManager notificationManager =
                    (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                Notification notification = new Notification(/* your notification */);
                PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0);
                notification.setLatestEventInfo(this, sns, sns2, pendingIntent);
                notificationManager.notify(0, notification);
      }
      }

如何修改sendNotification（）？ 謝謝

嘗試這個：

private void sendNotification(){

    CharSequence title = "The title";
    CharSequence message = "My message";

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
                      .setSmallIcon(R.drawable.ic_launcher)
                      .setAutoCancel(true)
                      .setContentTitle(title);

    mBuilder.setContentText(message);
    mBuilder.setTicker(message);
    mBuilder.setWhen(System.currentTimeMillis());

    NotificationManager notificationManager =   
           (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, new Intent(), 0);
    mBuilder.setContentIntent(pendingIntent);
    notificationManager.notify(0, mBuilder.build());
}
