如何解决Android通知问题？

我有需要时，一些事件发生如何解决Android通知问题？

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); 
*/ 


    } 

}

写在状态栏上的通知我称之为利用这个代码

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

一个服务，但我做了一些错误，我总是得到这个例外

你在哪里调用这个startService（新的意图（MainActivity.this，notif.class））; – apk

从其他活动活动 – Vahagn

您是否在清单文件中声明了此服务？ – apk

发现您并未调用Notification.setLatestEventInfo（）。这可能会导致崩溃尝试取消注释它
