listPlaylists returning list of LinkedTreeMap not Playlists

[Vichy97]

I think this has something to do with Gson

Could you elaborate further on what you are doing? This seems to work fine for me.

Edit
Are you maybe not displaying the desired List<Playlist>, but an internal object used by Gson while parsing the incoming JSON?

[Vichy97]

That is what the method listPlaylists() was returning and it was crashing when I tried to cast it to List<Playlist>. I will investigate some more though. It could be because Im using kotlin, but I'm not sure

I can't figure out what is going wrong.
Here is my code:

return Observable.fromCallable {
            val playlists: List<Playlist>  = googlePlayMusicService!!.playlistApi.listPlaylists()
            return@fromCallable playlists
        }

I dont think it has anything to do with Kotlin or RxJava. Apparently a lot of people have run into this issue with Gson when using Java generics.

[Vichy97]

The only way I was able to fix it was to serialize and deserialize

return Observable.fromCallable {
            val jsonString: String = Gson().toJson(googlePlayMusicService!!.playlistApi.listPlaylists())
            val playlists: List<Playlist> = Gson().fromJson(jsonString, object : TypeToken<List<Playlist>>() {}.type)
            return@fromCallable playlists
        }

but this is not ideal... :/

What Java version are you using?

Does gplaymusic:0.3.6-R0-SNAPSHOTwork for you?

[Vichy97]

hey I have not had a chance to test this since my app is not really building properly now (unrelated refactoring). I will let you know whenever I do test it though

It seems that a temporary solution has been found: #44 (comment)

This has been resolved in version 0.3.6
