How to create a session object in an application

Question

In my app i want to create a session for login and log out.

I dont have any idea how to work with session. Anybody help me by giving some sample example.

Answer 1

I think the session object should be a static object declared and initialized when your application starts running. I have met this problem and decided to put my session object in a utils class which contains mathods used by every activity in my app.

Here is a short example:

1. create a class for utils which will contain session object, Session is the class by which you implement your session object. It can contain, for example, userId, userName, etc.:

   public class Utils {  
       public static Session mySessionObject = null;
   }
   

2. When login button is pushed initialize your session object:

   login.setOnClickListener(new View.OnClickListener() {
       public void onClick(View v) {
           Utils.mySessionObject = new Session();
          //some extra initalization, for example setting userId
       }
   });
   

On logout you can destroy your session object.
