finally { Log.i("bai", " finally socket finally isConnected : "+ socket.isConnected()); Log.i("bai", "socket info : "+ socket.toString() ); Log.i("bai", "socket isConnected : "+ socket.isConnected()); if (null != socket) { try {// if(dis != null) {// dis.close();// } Log.i("bai", "socket isConnected null != socket: "+ socket.isConnected()); Log.i("bai", "socket.isClosed(): "+ socket.isClosed()); socket.setSoTimeout(0); } catch(SocketException se) { Log.i("bai",se.getMessage()); throw new PushException(se, ErrorType.Err_Read); } catch(IOException ie) { throw new PushException(ie, ErrorType.Err_Read); } } }这个finally是在read socket结束时执行，不过让人奇怪的是在socket不为空，还连接着的情况下，我设置socket永不超时就发现了setsockopt failed: EBADF (Bad file number)问题，导致socket异常关闭。网上也没找到详细资料，请各位道友帮忙看下，very thank you！！！

------解决方案--------------------
直接socket.close不行吗？为何还要加socket.setSoTimeout(0);呢？
如果要终止socket输入或者输出，可以加上：
- Java code
if(null != socket && socket.isConnected){socket.shutdownInput();socket.shutdownOutput();}
