        this.context = context;
        Realm.init(context);

        realmInstance = Realm.getDefaultInstance();
        PrintLog("RealmController", "RealmController", "Getting realm instance", LOG_LEVEL_INFO);

    public Date todaysDate;
    public int sellingData;

    public Date getTodaysDate() {

    public void setTodaysDate(Date todaysDate) {
        this.todaysDate = todaysDate;
    }
    public int getSellingData() {

回答1:

If you create a Realm with a given schema on the device, then if you start modifying the schema (by adding new classes, adding new fields, removing fields, adding/removing @Index, adding/removing @Required, changing a type, etc.) then you either need to provide a migration (example here), or you need to specify deleteIfMigrationNeeded() on your RealmConfiguration.

回答2:

If you have added a new model class. You need to uninstall the app and run again. It will solve the problem.
