如何修复Android通知问题？

I have a service which needs to write a notification on the status bar when some event occurs

我有一项服务,需要在某些事件发生时在状态栏上写一个通知

package com.octoplus.client.services;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;

import com.octoplus.client.MainActivity;
import com.octoplus.client.R;

import java.util.concurrent.TimeUnit;

public class notif extends Service {
    public notif() {
    }
    NotificationManager nm;
    @Override
    public IBinder onBind(Intent intent) {
        throw new UnsupportedOperationException("Not yet implemented");
    }
    @Override
    public void onCreate() {
        super.onCreate();
        nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    }
    public int onStartCommand(Intent intent, int flags, int startId) {

        sendNotif();
        return super.onStartCommand(intent, flags, startId);
    }

    void sendNotif() {
        // 1-я часть
        Notification notif = new Notification(R.drawable.ic_launcher, "We create gif", System.currentTimeMillis());
        // ставим флаг, чтобы уведомление пропало после нажатия
        notif.flags |= Notification.FLAG_AUTO_CANCEL;
        // отправляем
        nm.notify(1, notif);
/*
        // 3-я часть
        Intent intent = new Intent(this, MainActivity.class);
       // intent.putExtra(MainActivity.FILE_NAME, "somefile");
        PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0);

        // 2-я часть
        notif.setLatestEventInfo(this, "Notification's title", "Notification's text", pIntent);
*/


    }

}

I call it with use this code

我用这个代码调用它

startService(new Intent(MainActivity.this, notif.class));

but I made some mistake and I always get this exception

但我犯了一些错误,我总是得到这个例外

found that you are not calling Notification.setLatestEventInfo(). this might cause crash try uncommenting it

发现你没有调用Notification.setLatestEventInfo()。这可能导致崩溃尝试取消注释
