[Room] onCreate isn't called after databaseBuilder.build

Hi guys!
Firstly, I’m sorry this bad English I usually don’t speak or write English.

After my databaseBuilder(…).build(), the callback method [onCreated] isn’t called
I tried to put this line after build()…

instance.openHelper.writableDatabase

…the onCreated method is called!
But when I build on the cellphone the app is crashed, asking for MIGRATION_1_2.

I want an explanation, please :frowning:
I need the callback methods, but the DATABASE isn’t created calling only build(), why?

Edit:
I’ve already tried to reinstall the application too.

Follow my AppRoomDatabase

@Database(entities = [User::class, Setting::class], version = 1)
abstract class AppRoomDatabase : RoomDatabase() {

abstract fun userDAO(): UserDAO
abstract fun settingDAO(): SettingDAO

private class AppRoomCallback(private val scope: CoroutineScope) :
    RoomDatabase.Callback() {

    override fun onCreate(db: SupportSQLiteDatabase) {
        super.onCreate(db)
        INSTANCE?.let { database ->
            scope.launch {
                initialize(database)
            }
        }
    }

    suspend fun initialize(database: AppRoomDatabase) {
        val userDAO = database.userDAO()
        userDAO.insert(
            User(
                "demo",
                "demo",
                "Usuário Demonstração",
                "demo@testapp.com",
                1
            )
        )

        val settingDAO = database.settingDAO()
        settingDAO.insert(
            Setting(
                "DEFAULT",
                null,
                null,
                true,
                IpAddress("10.1.1.1", "8080"),
                Period(null, null)
            )
        )
    }
}

companion object {
    @Volatile
    private var INSTANCE: AppRoomDatabase? = null

    fun getDatabase(context: Context, scope: CoroutineScope): AppRoomDatabase {
        return INSTANCE ?: synchronized(this) {
            val instance = Room.databaseBuilder(
                context.applicationContext,
                AppRoomDatabase::class.java,
                "app_database")
                    .addCallback(AppRoomCallback(scope))
                    .build()

            INSTANCE = instance
            return@synchronized instance
        }
    }
}

}

I’ve been already tried to reinstall the application.
