大家好我有一个Web服务来帮助我完成登录过程 但是当我运行代码时,我收到错误说“应用程序意外停止了........

这是我的网络服务:

package org.webserv.ws;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

public class hello {
    public String authentication(String userName,String password) {
        String retrievedUserName = "";  
        String retrievedPassword = "";
        String status = "";

        try {
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/android           app.","","admin");
            PreparedStatement statement =  con.prepareStatement("SELECT * FROM user account info. WHERE    username = '"+userName+"'AND password = '"+password+"'");
            ResultSet result = statement.executeQuery();

            while(result.next()){
                retrievedUserName = result.getString("username");
                retrievedPassword = result.getString("password");
            }

            if(retrievedUserName.equals(userName)&&retrievedPassword.equals(password)){
                status = "Success!";
            }
            else { status = "Login fail!!!"; }

        }
        catch(Exception e) { e.printStackTrace(); }

        return status; 
    }
} 

这里是logcat

这是AndroidLoginExampleActivity.java文件

package com.androidlogin.ws;

@Override

    login.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) {
            loginAction();

        }
    });
}

private void loginAction(){
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    EditText userName = (EditText) findViewById(R.id.tf_userName);
    String user_Name = userName.getText().toString();
    EditText userPassword = (EditText) findViewById(R.id.tf_password);
    String user_Password = userPassword.getText().toString();

  //Pass value for userName variable of the web service
    PropertyInfo unameProp =new PropertyInfo();

    passwordProp.setName("password");

    request.addProperty(passwordProp);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    }
    catch(Exception e){

    }
   }

}

ksoap2-android-assembly-2.6.2-jar-with-dependencies.jar

添加此jar文件/ libs文件夹,以便Eclipse ADT自动将您的jar添加到应用程序的构建路径中。我希望这会对你有所帮助。

谢谢!
