Mess with the shared preferences of android - which function to use?

Here\'s a standard task: store some values in the application\'s shared preferences in order to be able to retrieve it later on. But one will discover that there are 3 funct

I am sharing mine, hope it will make life easy -

    public class SharedPreferenceStore {

    public static void deleteValue(Context context, String key) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        Editor editor = preferences.edit();
        editor.remove(key).apply();
    }

    public static void storeValue(Context context, String key, String value) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        Editor editor = preferences.edit();
        editor.putString(key, value).apply();
    }

    public static void storeValue(Context context, String key, boolean value) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        Editor editor = preferences.edit();
        editor.putBoolean(key, value).apply();
    }

    public static void storeValue(Context context, String key, double value) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        String doubleVal = String.valueOf(value);
        Editor editor = preferences.edit();
        editor.putString(key, doubleVal).apply();
    }

    public static void storeValue(Context context, String key, float value) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        Editor editor = preferences.edit();
        editor.putFloat(key, value).apply();
    }

    public static void storeValue(Context context, String key, long value) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        Editor editor = preferences.edit();
        editor.putLong(key, value).apply();
    }

    public static void storeValue(Context context, String key, int value) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        Editor editor = preferences.edit();
        editor.putInt(key, value).apply();
    }

    /*************************
     * GET Methods
     ***************************************/
    public static String getValue(Context context, String key, String defValue) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getString(key, defValue);
    }

    public static boolean getValue(Context context, String key, boolean defValue) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getBoolean(key, defValue);
    }

    public static double getValue(Context context, String key, double defValue) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        String doubleVal = String.valueOf(defValue);
        return Double.parseDouble(preferences.getString(key, doubleVal));
    }

    public static float getValue(Context context, String key, float defValue) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getFloat(key, defValue);
    }

    public static long getValue(Context context, String key, long defValue) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getLong(key, defValue);
    }

    public static int getValue(Context context, String key, int defValue) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getInt(key, defValue);
    }
}

Just use the class and forget about all complications of SharedPrefences. Hope it will help you :)
