Android 共享映像失败

我正试图分享一张

图片

，但我不知道为什么我失败了，你能帮我吗

String imageUrl = web.get(position).getImage();
    if (!imageUrl.startsWith("http://") && !imageUrl.startsWith("https://"))
        imageUrl = "http://" + imageUrl;

    Button button = (Button)rowView.findViewById(R.id.condividi);
    final String finalImageUrl = imageUrl;
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("image/*");
            intent.putExtra(Intent.EXTRA_TEXT, web.get(position).getTitle());
            File file = writebitmaptofilefirst("the image", finalImageUrl );
            Uri path = Uri.fromFile(file);
            intent.putExtra(Intent.EXTRA_STREAM, path );
            Intent send = Intent.createChooser(intent, null);
            context.startActivity(send);
        }
    });

向清单中添加权限

从文件名（图像）中删除空间。您需要使用空格来解码uri。您应该访问完整路径返回文件。getAbsolutePath（）。您正在传递文件名。
在文件存在的情况下，您的存储路径不相同。字典里没有包括你。extranlstoragepath+/temp_images/+the image.jpg尝试记录文件路径。及

File File=新文件（mFolder.getAbsolutePath（），filename+“.jpg”）

你错过了两个参数之间的一个

您遇到了什么问题？撞车？如果是，请张贴日志too@user2340612我没有崩溃，当我准备使用社交应用程序发送文件时，只会出现一条消息，如：共享失败，请重试（对于Whatsapp）或无法上传图像（对于Instagram）您确定需要

EXTRA_文本

和

EXTRA_流

EXTRA吗？我想你只需要第二个，但我需要与图像共享一些文本也许可以帮助你我尝试放置返回文件。getAbsolutePath（）但什么都没有你得到了什么？图像保存到存储？你添加权限了吗？我简直不敢相信：我添加的代码比我以前的代码好
