Custom Audio player

[Charles longwe]

i can play,pause and resume an audio. But if i want to play another song the songs play concurrency. Please help me how can I use unload() in SounderLoader whenever playing another song.

[Elliot Garbus]

I don’t think you need to use unload().   Do you have 1 sound object or are you creating multiple sound objects?

I suspect you were playing sounds, and never stopping them.  I changed the play button to a ToggleButton, and use the state of the button to stop or play songs.

Also, change the source to a StringProperty, as below.

from kivy.properties import NumericProperty, StringProperty
from kivymd.app import MDApp
from kivymd.uix.behaviors.toggle_behavior import MDToggleButton

from kivymd.uix.button import MDRoundFlatIconButton
from kivymd.uix.card import MDCard
