最近在开发同屏，做了个Dome，记录下成果！

首先是web端和服务器端，这里我使用node.js来做的

服务端：service.js

  1. var http = require('http');
  2. var sio = require('socket.io');
  3. var fs = require('fs');
  4. var server = http.createServer(function(req,res){
  5.     res.writeHead(200,
  6.         {
  7.             'Content-type':'text/html'
  8.         }
  9.     );
  10.     res.end(fs.readFileSync('./main.html'));
  11. });
  12.  
  13. server.listen(8083);
  14. var socket = sio.listen(server);
  15. var webs = socket;
  16. socket.on('connection',function(socket){
  17.     console.log("Connection...");
  18.  
  19. 	
  20. 	setTimeout(function(){
  21. 		socket.emit('news',{shuju:'data:image/png;base64,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

接下来是Android端，这里要求是在5.0以下版本上开发同屏功能，我找了好多网上案例，现在也只能做到截图传输，效果也不尽人意。

首先导入io.socket有关的jar包：engine.io-client-0.8.3.jar， okhttp-3.6.0.jar，okio-1.11.0.jar，socket.io-client-0.8.4-SNAPSHOT.jar

连接服务器：SocketStreamWork.java
