You might wanna see this library. It's Secure and Easy to use.

Sample Code:

SecurePrefManager.with(this)
            .set("user_name")
            .value("LoremIpsum")
            .go();

All you need to do is this (all the code is part of an acticity or Service (i.e. Context): Get a SharedPreferences object:

static final String PREFS_NAME = "MyPrefs";
static final String USER_KEY = "user";

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);

To store a string:

String username = ...
SharedPreferences.Editor editor = settings.edit();
editor.putString(USER_KEY, username);
editor.commit();

To read:

String username = settings.getString(USER_KEY,null); // 2nd param is default value, used if prefs value is undefined

Here are more details: http://developer.android.com/guide/topics/data/data-storage.html

To achieve that first create one class, in that class you need to write all the function regarding get and set value in the sharedpreference . Please look at this below Code.

public class SaveSharedPreference 
{
    static final String PREF_USER_NAME= "username";

    static SharedPreferences getSharedPreferences(Context ctx) {
        return PreferenceManager.getDefaultSharedPreferences(ctx);
    }

    public static void setUserName(Context ctx, String userName) 
    {
        Editor editor = getSharedPreferences(ctx).edit();
        editor.putBoolean(PREF_USER_NAME, userName);
        editor.commit();
    }

    public static boolean getUserName(Context ctx)
    {
        return getSharedPreferences(ctx).getString(PREF_USER_NAME, "");
    }
}

Now you can first set the value of username from a prticular activity and get the value of user name from any activity.
