Hello Guys, I'm using Android Architecture Components Room in my project and I have an Entity with a Enum class as a property. It's something like this:

@Entity(tableName = "tb_episode")
data class Episode (

    var title: String,
    
    var episodeType: EpisodeType
    ...
)

And I have the TypeConverter for it:

object Converters {

    @TypeConverter
    @JvmStatic
    fun toEnum(code: Int): EpisodeType {
        return when (code) {
            1 -> EpisodeType.PODCAST
            2 -> EpisodeType.ALBUM_REVIEW
            else -> EpisodeType.DEFAULT
        }
    }

    @TypeConverter
    @JvmStatic
    fun fromEnum(type: EpisodeType): Int {
        return when (type) {
            EpisodeType.PODCAST -> 1
            EpisodeType.ALBUM_REVIEW -> 2
            else -> 0
        }
    }
}

Also, I added the TypeConverters Annotation to my Database class:

@TypeConverters(Converters::class)
abstract class AppDatabase : RoomDatabase()

But when I try to run the App I get this message:

Class is referenced as a converter but it does not have any converter methods.

I don't know if Room doesn't support Kotlin Enum class or if I'm doing something wrong.

Anyone can help me with this?

@Carlos Ottoboni Instead of having your converter class be an object, make it an ordinary class and see if you get a different error message.

Hi there, I've made the changes but I'm still getting the same error.

class EpisodeTypeConverter {

    @TypeConverter
    fun toEpisodeType(value: Int): EpisodeType {
        return EpisodeType.values()[value]
    }

    @TypeConverter
    fun fromEpisodeType(value: EpisodeType): Int {
        return value.let { value.ordinal }
    }
}

@Entity(tableName = "tb_episode")
@TypeConverters(EpisodeTypeConverter::class)
data class Episode(
         ...
        @ColumnInfo(name = "episode_type")
        var episodeType: EpisodeType = EpisodeType.DEFAULT
)
