Change this:
if (resp_code.compareTo("200") == 0) {
System.out.println("response msg==" + resp_msg);
Toast.makeText(Registration.this, "response msg==" + resp_msg, Toast.LENGTH_SHORT).show();
}
To:
if (resp_code.equals("200")) {
System.out.println("response msg==" + resp_msg);
Toast.makeText(Registration.this, "response msg==" + resp_msg, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(Registration.this,"Donot Match",Toast.LENGTH_SHORT).show();
}

call compare_version() method in else condition

First you have to understand the different between the login success response and the login failed(on a wrong username password combination) response.
You are reading "res_response" value from your JSON response although it is not in your login failed response.
Also you did a mistake in your code by hard-coding resp_code = "200";

I know code is a mess. But any help will be appreciated.

Make sure you have the same name as property in your service and android parameters, for example request.addProperty("name",name) in the WebService public class Login(String name)

//in your both activity or create class

You can write and apply below mentioned steps (Please ignore any syntactical error, I am giving you simple logical steps).
step 1 - Make a global application level loginObject setter and getter like below. Make sure to define Application class in your manifest just like you do it for your LoginActivity
public class ApplicationClass extends Application{
private LoginBean loginObject;
public void setLoginBean(LoginBean object) {
this.loginObject = object;
}
public LoginBean getName() {
return this.loginObject
}
}
Step - 2 Get an instance of ApplicationClass object reference in LoginActivity to set this global loginObject
e.g. setLogin object in your current Loginactivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
appObject.setLoginBean(loginObject)
}
Step - 3 Get an instance of ApplicationClass object reference in any other Activity get this global loginObject where you need to access this login data.
e.g. getLogin object in your otherActivity like this
......
private ApplicationClass appObject;
......
#Override
protected void onCreate(Bundle savedInstanceState) {
......
appObject = (ApplicationClass) LoginActivity.this.getApplication();
.......
LoginBean loginObject = appObject.getLoginBean();
}
