android - 如何将挂起的 Intent 转换为 byte[]

Question

我正在开发通知监听器应用程序。在这里我收到所有通知。但是如何将未决 Intent 从通知转换为 byte[]，反之亦然。

   @Override public void onNotificationPosted(StatusBarNotification sbn) { 
     System.out.println("Notification_AGS: onNotificationPosted");
     if (SharedPreferenceManager.getPrefStoragePermission(context)) { 
       notificationList.clear();
       String packageName = sbn.getPackageName(); 
       PendingIntent pendingIntent = sbn.getNotification().contentIntent
     }
   }

Answer 1

您可以将 PendingIntent 序列化为 Parcel，然后将 Parcel 转换为字节数组，如下所示:

PendingIntent pendingIntent = ...
Parcel parcel = Parcel.obtain();
pendingIntent.pendingIntent.writeToParcel(parcel, 0);
byte[] bytes = parcel.marshall();

注意以下事项:

The documentation explicitly states that the resulting byte array should NOT be stored in a persistent storage because the byte array is a highly optimized serialized form and it is not guaranteed that the Parcel can be successfully recreated from the byte array.
