I can't init the InetSocketAddress, the exception is thrown when create InetSocketAddress. I run my app in android 2.3.4. 

    Log.i("Test", "Hien Connect host="+_host+" & port="+_port);
try 
{
    _socket_channel = SocketChannel.open();
    _socket_channel.configureBlocking(false);
            Log.i("Test", "Hien Connect 34");
    //InetSocketAddress socketAddress = new InetSocketAddress(InetAddress.getByAddress(b), _port);
    _socket_channel.connect(new InetSocketAddress(_host, _port));
    //_socket_channel.connect(socketAddress);

The output is below. When I run this app in android 4.1.2, the app can connet to server successfully. How can I use InitSocketAddress in android 2.3.3 and 2.3.4 ?

我找到了解决方案，当我在 MainActivity 中创建套接字并且 MainRenderer 中的另一个线程从 C 调用它时，这是我的错误，它使上述错误发生。当我在 MainRenderer 中创建套接字时，错误解决了！谢谢你的帮助 ！

尝试这个

    InetAddress serverAddr = InetAddress.getByName("120.119.112.168");
    SocketAddress sc_add= new InetSocketAddress(serverAddr,1234);
    _socket_channel.connect(sc_add);
