      今天实现了在同一WiFi网络下通过IP地址对图片的传输，但是只能传输小于1M的图片，对于超过1M的图片会因为连接时间过长而超时，不能传送成功。如果解决了大图片的传输问题，那么视频和音频是不是也就能很好的进行传输了呢？

      下面是传输小图片的代码（简单易懂，效率不太好）：

      代码引用于：http://blog.csdn.net/yuankundong/article/details/51489823；

      接收端：

public void ReceiveFile(){
        try{
            Socket name = server.accept();
            InputStream nameStream = name.getInputStream();
            InputStreamReader streamReader = new InputStreamReader(nameStream);
            BufferedReader br = new BufferedReader(streamReader);
            String fileName = br.readLine();
            br.close();
            streamReader.close();
            nameStream.close();
            name.close();
            SendMessage(0, "正在接收:" + fileName);

            Socket data = server.accept();
            InputStream dataStream = data.getInputStream();
            String savePath = Environment.getExternalStorageDirectory().getPath() + "/" + fileName;
            File f=new File(savePath);
            int i=0;
            while(f.exists())
            {//如果上传的文件发生重名，进行改名   
                i++;
                fileName = fileName.substring(0, fileName.indexOf(".")-1)+""+i+""+ fileName.substring(fileName.indexOf(".")); 
                savePath = Environment.getExternalStorageDirectory().getPath() + "/" + fileName;
                f=new File(savePath);
            }
            FileOutputStream file = new FileOutputStream(savePath, false);
            byte[] buffer = new byte[1024];
            int size = -1;
            while ((size = dataStream.read(buffer)) != -1){
                file.write(buffer, 0 ,size);
            }
            file.close();
            dataStream.close();
            data.close();
            SendMessage(0, fileName + "接收完成");
            
    }

     发送端：

public void SendFile(ArrayList<String> fileName,ArrayList<String> path, String ipAddress, int port){
        try {
            for (int i = 0; i < fileName.size(); i++){
                
                Socket name = new Socket(ipAddress, port);
                OutputStream outputName = name.getOutputStream();
                OutputStreamWriter outputWriter = new OutputStreamWriter(outputName);
                BufferedWriter bwName = new BufferedWriter(outputWriter);
                bwName.write(fileName.get(i));
                bwName.close();
                outputWriter.close();
                outputName.close();
                name.close();
                SendMessage(0, "正在发送" + fileName.get(i));

                Socket data = new Socket(ipAddress, port);
                OutputStream outputData = data.getOutputStream();
                FileInputStream fileInput = new FileInputStream(path.get(i));
                
                int size = -1;
                byte[] buffer = new byte[1024];
                while((size = fileInput.read(buffer, 0, 1024)) != -1){
                    outputData.write(buffer, 0, size);
                }
                outputData.close();
                fileInput.close();
                data.close();
                SendMessage(0, fileName.get(i) + "  发送完成");
                 
    }
