Java Android套接字到服务器，服务器报告“；“连接重置”；错误

我正在为电子邮件系统开发一个Android应用程序，该应用程序需要连接服务器（由我的合作伙伴编写）。 我的手机使用PC生成的wifi，当我尝试登录时，服务器在10秒内只报告了几次“连接重置”错误

我在Android中调试，发现代码在执行后停止

client = new Socket(ServerInfo.sockethost, ServerInfo.socketport);

服务器会在这之后报告错误

这是客户端代码

public class Login extends Activity {

private Intent intent = null;
private EditText account = null; //Account
private EditText passwpord = null; //password
private Button login = null; // login
private TextView register = null; // register

private String useraccount = null;

private Dialog m_Dialog = null; // dialog

private Socket client; //client socket
private BufferedReader reader;
private PrintWriter writer;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    intent = this.getIntent();

    account = (EditText) this.findViewById(R.id.login_account);
    passwpord = (EditText) this.findViewById(R.id.login_password);
    login = (Button) this.findViewById(R.id.login_button);
    register = (TextView) this.findViewById(R.id.login_register);

    register.setClickable(true);
    //login button event
    login.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            useraccount = account.getText().toString();
            userpassword = account.getText().toString();

            //judge whether the account is null
            if (Regex.isEmpty(useraccount)) {

}

当我独立于应用程序执行客户机代码时，它工作得很好

有什么问题？您有什么建议吗？

我看不出有什么问题，但如果服务器多次报告相同的错误，肯定会出现严重问题。问题就在那一头。显然，在流结束后，他仍在继续使用套接字。您是否设置了访问网络的正确权限？日志中是否有任何异常？是的。我有。登录“logcat”显示编码在新套接字（）之后停止。在长时间尝试与服务器建立连接后，它会报告异常。【连接超时】由于连接超时，您无法对从未存在的连接进行“连接重置”。下定决心吧。你的问题是什么？
