Manage stored list

[GauvainSeigneur]

Hi, I followed your great tutorial. It help me a lot!
I have a fragment which display all song and a fragment which display songs of an album when I click on it.
When i click the on a song item (from songFragment or albumDetailFragment) it store the index of the list. But when I want to display a song from an another list it displays the song at the index of the first selected list...
My question is how to redefine list stored in StorageUtils ? thank you in advance
