แอพ Android ของฉันต้องทำให้วัตถุเป็นอนุกรม (RowCreation) เพื่อส่งผ่านเครือข่าย เห็นได้ชัดว่าคลาสอ็อบเจ็กต์ใช้อินเทอร์เฟซแบบอนุกรม ชั้นเรียนมีโครงสร้างดังต่อไปนี้:
public class RowCreation extends ClientSyncRequest {
private static final long serialVersionUID = 10001243L;
public int localID;
public int entity;
public Hashtable attributes = new Hashtable();
public byte[] bytes;
public long time = 0;
public String md5CheckSum;
}
public class ClientSyncRequest extends SyncMessage {
private static final long serialVersionUID = 10001246L;
public int id = 0;
public int getId(){
return this.id;
}
}
public class SyncMessage implements Serializable{
private static final long serialVersionUID = 10001231L;
}
มันเกิดขึ้นที่ผู้ใช้แอปรายหนึ่งรายงานข้อผิดพลาดในวันนี้ เมื่อฉันเห็น stacktrace บนคอนโซล Google Play คือ StackOverflowError:
