hello every body, iam new user of app inventor and I face some problems in amusic player in my app.
1- the slider working when i use (curent position) but not working when i use (from user)... one of them cancel the else.
2- when i use next or previouse button, it worked depend on the selected one in list not the song which alraedy playing.
3- when the song completed didn't transform to the next automatic ... why or how i can do that?
4- can i do repeat button in app inv.( where if the user want to repeat one song only or repeat all the list click on it ).
i shared my blocks
I wish some one help me to solve any of them or all
thank you

You are missing a Play list variable.

That would hold the list of selection indexes from the song list that the user has selected but have not yet started playing.

:question:

What is the source of the songs? Show the content of "global source". And please post images / screenshots of your blocks in good quality and ideally also post the aia.

ok. i will try to do a variable...
Thank you.



Thank you.
Are the pictures clear?

The Google Drive link should be publicly accessible.

I edit it.

And again, please explain...

Try something like this:

Thank you so much Anke.
the problem of the next and previous buttons is solved.
for the slider :
when i remove the first block in the image ( clock1 event) .... the thumb is moving (from user) but still there is a problem where the end-time lable become equal zero not the full duration of the song.
when i put the first block, it cancel the thumb from user.

I think i solved it ...
