This is my first comment so sorry if it isn't structured the way it should.

Im using a model with a costume variable with the type org.joda.time.DateTime, i've added a costume serializer for this type but im getting a NullPointerException. This Exception occurs on line 95 in the SQLiteUtils.java file and it's because the type of the column is null.

I think the problem has to do with line 45 and 46 in the file DatebaseInfo.java, the custom serializers are loaded after the models. Can you verify this or am i doing something wrong?

DatebaseInfo.java

public DatabaseInfo(Context context, @NonNull DatabaseConfig databaseConfig) {
        loadModels(context, databaseConfig); //These two lines
        loadTypeSerializers(databaseConfig); //These two lines

        this.reActiveOpenHelper = new ReActiveOpenHelper(context, databaseConfig, tableInfos.values());

        ReActiveLog.i(LogLevel.BASIC, "Tables info for database " + databaseConfig.databaseName + " loaded.");
}

My Serializer class:

public final class DateSerializer extends TypeSerializer<DateTime, Long> {

    @Nullable
    public Long serialize(@NonNull DateTime date) {
        return date.getMillis();
    }

    @Nullable
    public DateTime deserialize(@NonNull Long date) {
        return new DateTime(date);
    }
}

Console output:
