我是android新手。我在android中使用Socket。我在下面写了这些代码， 但它在连接服务器时会出现异常，
06-15 04：48：34.615：V / tcpserver（801）：2000ms后无法连接到/192.168.1.**（端口 * *）
我如何处理这些？任何建议， 提前致谢

答案 0 :(得分：0)
尝试使用InetAddress，将其更改为：
try{
socket=new Socket();
Log.i("UI", "values are "+ip_address2+","+portInt2+"socket port;"+socket.getInetAddress());
InetAddress addr = InetAddress.getByName(ip_address2);
SocketAddress remoteAddr = new InetSocketAddress(addr, portInt2);
// Allow some more time to timeout, 10-15 seconds
// if it is on the same network it may works, but if it is in the internet may be not.
socket.connect(remoteAddr, 12000);
if(socket.isConnected()){
Log.i("UI", "Socket is connected at ip"+ip_address2);
}
else
Log.i("UI", "Socket is Disconnected at ip"+ip_address2);
}
catch(IOException e){
socket=new Socket();
Log.v("tcpserver", e.getMessage());
}
