I have developed one login form android application.here if my login is success means the fetch the email for that login user and display the next activity textview.how can i do.

These is my soap webservice code:

Quote:

package com.xcart;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class Getemail {

[Code]....

Here i have to run these java application means email is displayed successfully while login is success..otherwise login is failed message displayed well.

These is my android code:

Quote:

public class CustomerLogin extends Activity {
private static final String SPF_NAME = "vidslogin";
private static final String USERNAME = "login";
private static final String PASSWORD = "password";
private static final String PREFS_NAME = null;

[Code]...
