activity-level preferences

[N00Bie]

Hello!

This is my first post here so kindly excuse me if this is in the wrong place.

Ok, this is how I have done the example of "Shared preferences", this is in my helper preferences class:

  public static final String GAME_PREFERENCES = "GamePrefs";

and this is in one of my activity's classes:

// Adding data

       SharedPreferences settings = 
         getSharedPreferences(GAME_PREFERENCES, MODE_PRIVATE); 
         SharedPreferences.Editor prefEditor = settings.edit(); 
         prefEditor.putString("lastLaunch", returnTimeAndDateFormatted()); 
         prefEditor.commit();

// Reading
         SharedPreferences settings2 = 
             getSharedPreferences(GAME_PREFERENCES, MODE_PRIVATE);
             if (settings2.contains("lastLaunch") == true) { 
//               System.err.println(settings2.getString("lastLaunch", "Default"));
                 Log.i("LASTLAUNCH", settings2.getString("lastLaunch", "Not LastLaunch value found!"));
             }

The above is for "shared preferences".

How do I do this for non shared, activity only preferences?

I found this code after googling:

SharedPreferences activityPreferences = this.getPreferences(MODE_PRIVATE);
String lastLaunch = activityPreferences.getString("lastLaunch", "Not Launched");

but if I get it right that is only to get something that has already been set, it does not say how to set it...

I am so damn confused
