使用Android Notifcations時運行時異常。

Question

這是我的CreateNotification類。代碼已從android頁面中獲取。 http://developer.android.com/guide/topics/ui/notifiers/notifications.html

代碼：

package your.notification.manager; 

import android.app.Activity; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 
import android.os.Parcel; 
import android.view.View; 

public class CreateNotification extends Activity { 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     String ns = Context.NOTIFICATION_SERVICE; 
     NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); 
     int icon = R.drawable.ic_launcher; 
     CharSequence tickerText = "Hello"; 
     long when = System.currentTimeMillis(); 

     Notification notification = new Notification(icon, tickerText, when); 
     Context context = getApplicationContext(); 
     CharSequence contentTitle = "My notification"; 
     CharSequence contentText = "Hello World!"; 
     Intent notificationIntent = new Intent(this, NotificationReceiver.class); 
     PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 

     notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); 
     final int HELLO_ID = 1; 

     mNotificationManager.notify(HELLO_ID, notification); 

    } 


} 

錯誤：

05-05 12:51:38.687: E/AndroidRuntime(8629): Caused by: java.lang.IllegalArgumentException: contentView required: pkg=com.crumbs.main id=0 notification=Notification(vibrate=null,sound=null,defaults=0x0,flags=0x10)

你的代碼工作正常..

只是清理項目，然後再次運行。
