我已经尝试并尝试在两个android设备之间发送图片，但是我无法弄清楚传输问题。我修改了wile循环甚至消除了循环，但它仍然不起作用。当我在设备上测试我的项目时，连接没有问题。但是，随着传输任务的开始，发送客户端停止，接收端出现“传输错误”消息。有谁知道我可以对我的程序做些什么？这是我发送和接收的两个主要部分。

我将非常感谢任何帮助。谢谢你。

发送部分：

new Thread() {  
        public void run() {
            try {  
                File file = new File("/storage/emulated/0/Pic/img3.jpg");
                s = new Socket("192.168.1.106", 1234); 
                FileInputStream fis = new FileInputStream(file); 
                din = new DataInputStream(new BufferedInputStream(fis)); 
                dout = new DataOutputStream(s.getOutputStream());  
                dout.writeUTF(String.valueOf(file.length())); 
                byte[] buffer = new byte[1024];  
                int len = 0;  
                /*while ((len = din.read(buffer)) != -1) {  
                    dout.write(buffer, 0, len); 
                }  */
                dout.write(din.read());
                dout.flush();  

            } catch (IOException e) {  
                System.out.println(e.toString());  
            }

您需要在这里查看显示如何通过套接字发送图像的答案：通过套接字问题发送图像流 - Android 

FileInputStream fileInputStream = new FileInputStream( "my_image_file_path" );

int nRead;
byte[] data = new byte[16384];

try {
    while( (nRead = fileInputStream.read(data, 0, data.length)) != -1 ){
        networkOutputStream.write( data, 0, nRead );
    }

} catch( IOException e ){
    e.printStackTrace();
}
fileInputStream.close();
