Shared Pref returning wrong value in some high end devices like samsung

Question

below is my code for creating shared pref

public SaveData(Context con) {
    this.context = con;
    emailSharedPreferences = context.getSharedPreferences(KEY_PREF_EMAIL, Context.MODE_PRIVATE);
    emailEdit = emailSharedPreferences.edit();
}

for set data

public void setData(boolean accepted) {
    emailEdit = emailSharedPreferences.edit();
    emailEdit.putBoolean(KEY, accepted);
    emailEdit.apply();
}

for get data

public Boolean getData() {
    emailSharedPreferences = context.getSharedPreferences(KEY_PREF_EMAIL, Context.MODE_PRIVATE);
    return emailSharedPreferences.getBoolean(KEY, false);
}

At my application launcher screen when i am trying to get data it is returning "true" in some devices.

Now if I have created shared pref by below code

 private static SharedPreferences getPreferences(Context context) {
   // return context.getSharedPreferences(PREF_NAME, MODE);
    return  PreferenceManager.getDefaultSharedPreferences(context);

}

private static SharedPreferences.Editor getEditor(Context context) {
    return getPreferences(context).edit();
}

For set data

public static void setData(Context context,boolean value){
    try {
        getEditor(context).putBoolean(KEY, value).commit();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

for get data

 public static boolean getData(Context context){
    try {
        return getPreferences(context).getBoolean(KEY, false);
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

now it is working fine on all devices. Can someone explain this why this is happening.

Answer 1

Use this

emailEdit.commit();

after this

emailEdit.putBoolean(KEY, accepted);
