android - ByteArray Property Too Large to send within putExtra ("obj", obj) of intent 打开另一个 Activity 时

Question

我有一个具有 string、int、double、byte[] 属性的对象。我的 byte[] 正在存储来自数据库的图像，因为我将图像以字节形式存储在我的表中。

问题是，当我序列化对象并通过 intent.puteExtra("obj", obj) 传递对象时，应用程序崩溃，控制台中没有任何错误。

然后我让我的 byte[] property = byte[1] 并且所有的工作都在 activity swithed 并且数据通过了 intent。

这是我的销售对象:

import android.media.Image;
import android.os.Parcel;
import android.os.Parcelable;

import java.io.Serializable;
import java.util.Date;

public class Sell extends Product implements Serializable
{
public byte[] Image1;
public byte[] Image1a;

public byte[] Image2;
public byte[] Image3;
public byte[] Image4;
public String postcode;
public double postage;
public int isDelivered ;





public Sell(int p_Id, String p_u_id, double price, String title, String description, int category, String tags,
            byte[] image1, byte[] image2, byte[] image3, byte[] image4
            , String postcode, double postage, int isDelivered, String date, int type)
{

    super(p_Id, p_u_id,price,title,description,category,tags, type, date);
    this.Image1 = image1;
    this.Image2 = image2;
    this.Image3 = image3;
    this.Image4 = image4;
    this.postcode = postcode;
    this.postage = postage;
    this.isDelivered = isDelivered;


}

}

这是我的产品对象:

package com.asianretail.trikam.asianretail;

import android.os.Parcel;
import android.os.Parcelable;

import java.io.Serializable;

public class Product implements Serializable {

public  int p_Id;
public String P_U_Id;
public double Price;
public int Category;
public String Tags;
public String Title;
public String Description;
public int Type;
public String Date;

public Product(int p_Id, String p_u_id, double price, String title, String description, int category, String tags, int type, String date)
{

    this.Date = date;
    this.p_Id = p_Id;
    this.P_U_Id = p_u_id;
    this.Price = price;
    this.Title = title;
    this.Description = description;
    this.Category = category;
    this.Tags = tags;
    this.Type = type;

}
}

要从 fragment 开始 Activity ，我使用这个:

Product prod = null;
                                for(int i = 0; i < pObj.size(); i++){
                                    if(((Product)pObj.get(i)).p_Id == ((int)v.getTag())){
                                        prod = (Product)pObj.get(i);
                                    }
                                }
                                Bundle bundle = new Bundle();
                                bundle.putSerializable("valueProd", prod);

                                Intent i = new Intent(getActivity(), ProductActivity.class);
                                i.putExtra("bundleProd", bundle);
                                startActivity(i);

最好将字节数组写入文件并将文件的 url 传递给 bundle。你不应该在 bundle 中传递图像，因为它可能会尝试访问比分配的内存更多的内存，以防你的字节数组太大。
