Answer 1

Use these method to save and get values from any where in your app change parameter according to your requirment

this method to save value in shared prefrences

public static void setPref(Context c, String pref, String val) {
    Editor e = PreferenceManager.getDefaultSharedPreferences(c).edit();
    e.putString(pref, val);
    e.commit();
}

this method to get value from shared prefrences

public static String getPref(Context c, String pref, String val) {
    return PreferenceManager.getDefaultSharedPreferences(c).getString(pref,
            val);
}
