RingtoneManager - choosing an MP3 a second time problem

When using the ringtonemanager - like the example below - is there a way to check to see if the bounce.mp3 has already been added to the mediastore (without invoking ringtone picker)? I am setting the ringtone in the background from a list of possible MP3s, and what I notice is that the first time an MP3 is selected it works ok. If I choose the same MP3 from the list again - it raises a null pointer on the AddToMediaStore line.

B4X:
Dim r As RingtoneManager
Dim u As String
u = r.AddToMediaStore(File.DirRootExternal, "bounce.mp3", "Bounce!", True, True, True, True)
r.SetDefault(r.TYPE_RINGTONE, u)

Strange thing is - I just tested a prior version of what I was doing and I don't get any error. Other than a different mp3 name - the code is the same. Perhaps I went wrong elsewhere in my app that is impacting this now - it always works the first time selecting an MP3 and not the second. Attached is the log.

Also, What do you mean by save the Uri in a file?

Thanks!

Why do you need to add the same ringtone again? You will just end up cluttering the ringtone list.

You should instead add it only on the first time your application runs and save the returned value in a file. Now you can read the Uri from the file and access the ringtone.

I don't want to add it a second time - but wanted to see what happened if a user clicked the same entry a second time.
