无法在 Dsphotoeditor sdk 中传递图像 uri

Question

Image.java class

package com.example.memelogy;


import android.net.Uri;
import android.util.Base64;


public class Image {

    private byte[] image;

    public Image(byte[] image) {

        this.image = image;

    }


    public byte[] getImage() {
        return image;
    }

    public void setImage(byte[] image) {
        this.image = image;
    }
}

我正在尝试将图像 uri 发送到其他活动（使用 DsPhotoEditor sdk，因此无法更改其活动代码），我已经编写了观看 yt 视频的代码，该视频指导如何存储图像并在 gridview 中显示。我成功地检索了我的图像自己创建的名为 editimage.java 的活动显示并提供编辑图像的菜单。图像 。在主要活动中，图像显示在 gridview 中，当我长按特定图像时，它会显示警报对话框，其中有两个选项编辑和取消当我点击编辑时它会将图像发送到 editimage 活动（成功工作）。由于时间限制，我无法为图像过滤器编码，在图像上放置贴纸和文本。所以我正在使用 sdk(DsPhotoEditor)，它提供了我想在我的应用程序中实现的功能。当我按照我之前的描述从对话框中选择编辑时，它显示如下异常。sdk 活动仅接受 imageuri，而我不知道如何在我的代码中执行此操作。请帮助解决： `23-05-07 11:04:33.380 1909-1909/?
