Android Question Error using RingtoneManager

Hello, I'm trying to use RingtoneManager but I'm always getting this error... what could I do wrong?

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.net.Uri.toString()' on a null object reference

I'm using this code:
B4X:
Sub setRingtoneButton_Click
    Dim r As RingtoneManager
    Dim u As String
    u = r.AddToMediaStore(File.DirRootExternal, nomeConMp3, nomeFileCheSuona, False, False, True, False)
    r.SetDefault(r.TYPE_RINGTONE, u)
  
End Sub
and the error is on "u = r.AddToMediaStore"....

When I try the mp3 file with MediaPlayer it sounds fine:
B4X:
MediaPlayer1.Load(File.DirAssets, nomeConMp3)
MediaPlayer1.Play

Any help would be highly appreciated as I'm stuck...

Can you post the full error message from the logs?

What is the value of Log(u) ?
This is the full error message:

About the value of Log(u) It doesn't appear at all as the error start on line:
B4X:
u = r.AddToMediaStore(File.DirRootExternal, nomeConMp3, nomeFileCheSuona, False, False, True, False)
so log is not called at all

Check the unfiltered logs. Maybe there will be more information there.

Can you upload the audio file?
This is the unfiltered log:

What is the output of:
B4X:
Log(nomeConMp3)
Log(File.Exists(File.DirRootExternal, nomeConMp3))
I figured out everything... my mistake was I did not copy the ringtone in DirRootExternal before... now it is working fine.
Thanks a lot for your help Erel

I have the same problem but I get an error.

B4X:
Sub Button1_Click
    Log(1)
    Log(File.Exists(File.DirRootExternal, "1"))
   
    Dim r As RingtoneManager
    Dim u As String


    u = r.AddToMediaStore(File.DirRootExternal, "1.mp3", 1, False, False, True, False)
    r.SetDefault(r.TYPE_RINGTONE, u)

End Sub

It will work on the first time you try to add the ringtone. You cannot add the same file multiple times.

You can do something like:
B4X:
Sub Button1_Click
   Dim r As RingtoneManager
   Dim u As String
   If File.Exists(File.DirRootExternal, "1.mp3") = False Then
     File.Copy(File.DirAssets, "1.mp3", File.DirRootExternal, "1.mp3")
   End If
   Try
     u = r.AddToMediaStore(File.DirRootExternal, "1.mp3", 1, False, False, True, False) 'will fail if the file was added in the past.
     File.WriteString(File.DirInternal, "uri.txt", u)
   Catch
     u = File.ReadString(File.DirInternal, "uri.txt") 
   End Try
   r.SetDefault(r.TYPE_RINGTONE, u)
   r.Play(u)
End Sub
