public RealmController(Context context) {
    try {
        this.context = context;
        Realm.init(context);
        PrintLog("RealmController", "RealmController", "Init realm", LOG_LEVEL_INFO);
        realmInstance = Realm.getDefaultInstance();
        PrintLog("RealmController", "RealmController", "Getting realm instance", LOG_LEVEL_INFO);
    }
    catch (Exception err) {
        PrintLog("RealmController", "RealmController", "Error: " + err.getMessage(), LOG_LEVEL_ERROR);
    }
}

SellingData.java

public class SellingDataTable extends RealmObject {

    public Date todaysDate;
    public int sellingData;

    public Date getTodaysDate() {
        return todaysDate;
    }
    public void setTodaysDate(Date todaysDate) {
        this.todaysDate = todaysDate;
    }
    public int getSellingData() {
        return sellingData;
    }
    public void setSellingData(int sellingData) {

实际行为

08-09 15:24:16.120 [RealmController] {RealmController} (Init realm)
08-09 15:24:16.129 [RealmController] {RealmController} (Error: The 'SellingDataTable' class is missing from the schema for this Realm.)

Answer 1

如果您在设备上创建具有给定架构的Realm，那么如果您开始修改架构（通过添加新类，添加新字段，删除字段，添加/删除@Index，添加/删除{{ 1}}，更改类型等）然后您需要提供迁移（例如here），或者您需要在RealmConfiguration上指定@Required。

Answer 2

如果您添加了新的模型类。您需要卸载该应用并再次运行。它将解决问题。
