Question

我使用以下代码连接到套接字服务器：

XMPPConnection connection;
@Override
protected void onCreate(Bundle savedInstanceState) {
        Thread t=new Thread(new Runnable() {

            @Override
            public void run() {
                ConnectionConfiguration connConfig=new ConnectionConfiguration("178.62.84.123", 5222,"localhost");
                connection=new XMPPTCPConnection(connConfig);
                try{
                    connection.connect();
                }catch(XMPPException ex) {
                    setConnection(null);
                } catch (SmackException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        });
        t.start();
}
private void onPause() {
     try {
          connection.disconnect();
     } catch (NotConnectedException e) {
          e.printStackTrace();
     }
}

我在线程中设置connection变量。但是当我尝试断开我的应用程序崩溃时。

logcat的：

02-02 14:16:15.080: E/XMPPConnection(8047): Error in listener while closing connection

为什么尝试与ui线程断开连接？我在另一个帖子中设置connection。

在此示例中，在线程内调用断开连接，因此它不会阻止等待网络消息的UI。但是，在此示例中，我不重新连接，您应该将其实现为正确的状态（可能是OnResume）。

XMPPConnection connection = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
        Thread t=new Thread(new Runnable() {

            @Override
            public void run() {
                ConnectionConfiguration connConfig=new ConnectionConfiguration("178.62.84.123", 5222,"localhost");
                connection=new XMPPTCPConnection(connConfig);
                try{
                connection.connect();
            }catch(XMPPException ex) {
                setConnection(null);
            } catch (SmackException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    });
    t.start();
}
private void onPause() {
    Thread t=new Thread(new Runnable() {

        @Override
        public void run() {
               try {
                    if (connection != null)
                        connection.disconnect();
               } catch (NotConnectedException e) {

               }
        }
    });
    t.start();
}

在另一个线程内设置套接字连接
