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.

why are you trying for a session object. Are you just trying to keep something in memory until the app closes? — blessanm86, Sep 12 '11 at 10:25

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:

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;
}
```

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.

Here is a link telling more about sessions.

if you login by clicking a button, initialize your session object when the button is clicked – superM Sep 12 '11 at 09:53
Sure, I've added it to my answer. – superM Sep 12 '11 at 09:59
Session is not taking in my app why? – Jyosna Sep 12 '11 at 10:03
What do you mean by "is not taking in my app"? – superM Sep 12 '11 at 10:05
for example if u write Button btnLogin; then asking for import button . but public static Session mySessionObject = null; this is shoing err for Session ,, no imports are there – Jyosna Sep 12 '11 at 10:07
oh. Of course you must have a Session class adapted for your need and you should import it where neseccary. – superM Sep 12 '11 at 10:09

If you're trying to keep some data in memory during the life of your app, maybe you should consider using a singleton pattern. I use it this way.

public class Session {  

    @SuppressWarnings("unused")
    private GoogleAnalyticsTracker mGoogleAnalyticsTracker = null;

    private static Session sInstance               = null;

    private Session(Context pContext) {

        mGoogleAnalyticsTracker = GoogleAnalyticsTracker.getInstance();
        mGoogleAnalyticsTracker.startNewSession(pContext.getString(R.string.google_analytics_web_property_id), 
                                                pContext.getResources().getInteger(R.integer.google_analytics_tracking_time_in_seconds),
                                                pContext.getApplicationContext());
    }

    public static void init(Context pContext) {
        sInstance = new Session(pContext);
    }

    public static Session getInstance() {
        return sInstance;
    }
}

I load the session during the splash screen. Keep in mind that with this solution you shouldn't keep big objects in memory.

Session.init(this);

For example I use it for the Google Analytics tracker initialization, development mode, etc
