08_StoreFavoriteFoodsInRoomDatabase

[Keesdil]

Hello Peter,

Following your development for nutrilicious app i did not manage to get the recyclerview loaded with "favorites".
I guess something goes wrong with observeFavorites() in Favoritesfragment.
For the line :
favorites.observe(this@FavoritesFragment, Observer { foods ->
foods?.let {
launch(UI) {
(rvFavorites.adapter as? SearchListAdapter)?.setItems(foods)
}
}

the app crashes with :
"java.lang.IllegalStateException: Cannot invoke observe on a background thread"

Also use of "launch" as in your examples is deprecated, changes i made to overcome did not lead to this crash but did not load the recyclerview either.

Hope this helps to help me further..
