Android應用程序在執行通知代碼時崩潰

Question

這適用於模擬器，但安裝在設備上時會導致應用程序崩潰。

String frndName=getSharedData("myOnlineFriendName"); 
Intent intent = new Intent(this, MainActivity.class); 
PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0); 
Notification noti = new Notification.Builder(this) 
    .setContentTitle("Trace Me! Notification") 
    .setContentText(frndName+"'s New Location:") 
    .setSmallIcon(R.drawable.ic_launcher) 
    .setContentIntent(pIntent) 
    .addAction(R.drawable.ic_launcher, "And more", pIntent).build(); 

NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE); 
playSound("n"); 
noti.flags |= Notification.FLAG_AUTO_CANCEL; 
notificationManager.notify(0, noti); 

我該如何解決這個問題？

你下面的代碼是在API LEVEL 11 or ABOVE可用。這就是爲什麼它在API 11級別以下。

的是insted的，你可以用這樣的方式..你必須在你的res/lib文件夾添加android-support-v4.jar也這樣做：your Project property ---> Build Path --> add jar.和your Project property ---> Build Path --> order & export --> select all。在此之後清除&運行下面的代碼。

String frndName = "myOnlineFriendName"; 
     Intent intent = new Intent(this, MainActivity.class); 
     PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent, 0); 
     Notification noti = new NotificationCompat.Builder(this) 
       .setContentTitle("Trace Me! Notification") 
       .setContentText(frndName + "'s New Location:") 
       .setSmallIcon(R.drawable.ic_launcher).setContentIntent(pIntent) 
       .addAction(R.drawable.ic_launcher, "And more", pIntent).build(); 

     NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
     // playSound("n"); 
     noti.flags |= Notification.FLAG_AUTO_CANCEL; 
     notificationManager.notify(0, noti); 

你可以檢查你的代碼工作在我Android 2.1 Device

以上API 11：
