Create session using SharedPreferences.

public class Session {

    private SharedPreferences prefs;

    public Session(Context cntx) {
        // TODO Auto-generated constructor stub
        prefs = PreferenceManager.getDefaultSharedPreferences(cntx);
    }

    public void setusename(String usename) {
        prefs.edit().putString("usename", usename).commit();

    }

    public String getusename() {
        String usename = prefs.getString("usename","");
        return usename;
    }
}

now after making this class when u want to use this use like this make object og this class like

private Session session;//global variable 
session = new Session(cntx); //in oncreate 
//and now we set sharedpreference then use this like

session.setusename("USERNAME");
now when ever u want to get username then same work for session object and call this

session.getusename();

best of luck :) same for password

I use DefaultHttpClient with HttpRequestInterceptor and HttpResponseInterceptor. Something similar to this:

public class HTTPClients {

    private static DefaultHttpClient _defaultClient;
    private static String session_id;
    private static HTTPClients _me;
    private HTTPClients() {

    }
    public static DefaultHttpClient getDefaultHttpClient(){
        if ( _defaultClient == null ) {
            _defaultClient = new DefaultHttpClient();
            _me = new HTTPClients();
            _defaultClient.addResponseInterceptor(_me.new SessionKeeper());
            _defaultClient.addRequestInterceptor(_me.new SessionAdder());
        }
        return _defaultClient;
    }

    private class SessionAdder implements HttpRequestInterceptor {

        @Override
        public void process(HttpRequest request, HttpContext context)
                throws HttpException, IOException {
            Log.d("SessionKeeper", "Adding session with the following string: " + session_id);
            if ( session_id != null ) {
                request.setHeader("Cookie", session_id);
            }
        }

    }

    private class SessionKeeper implements HttpResponseInterceptor {

        @Override
        public void process(HttpResponse response, HttpContext context)
                throws HttpException, IOException {
            Header[] headers = response.getHeaders("Set-Cookie");
            if ( headers != null && headers.length == 1 ){
                Log.d("SessionKeeper", "Keeping session with the following string: " + headers[0].getValue());
                session_id = headers[0].getValue();
            }
        }

    }
}

Please look at the above link. It is detailed pretty well.

Use a singleton to maintain the user session.

try

public class Session {
private static String sessionId;
private static String userRole;

public static void setSessionId(String sessionId) {
    Session.sessionId = sessionId;
}

public static String getSessionId() {
    return sessionId;
}

}

Use this class and import it in every other activity. You can define your own functions to maintain your specific session data
