HATA error: Entities and Pojos must have a usable public constructor. You can have an empty constructor or a constructor whose parameters match the fields (by name and type).
Tried the following constructors but they failed to match:
PlaylistStreamEntity(long,long,int) -> [param:playlistUid -> matched field:playlistUid, param:streamUid -> matched field:streamUid, param:index -> matched field:unmatched]

empty constructor oluşturusan çözülür.

public PlaylistStreamEntity() { }
