You just update the global variable img inside imageSet(), but forget to update the image of the label using panel.config(image=img):

Cannot reproduce your error with the code you have posted. But I suspect that in your actual code you are using PlayButton, which calls PlaySongScreen.play. If that is what you are actually doing, then that is the cause of your problem. If you access PlaySongScreen.play, you are accessing the ObjectProperty, not the Button with id play_pause. You must access the play_btn attribute through the instance of PlaySongScreen, not the the class itself.

The way your posted code does it is correct. Using a Button with on_press set to root.play. The root is the instance of PlaySongScreen.

My problem is solved, I will mention the reason so that if someone has this problem, it will be useful for him, the reason is this:

The method I used, which I coded above, only checked /sdcard/emulated/0, which would cause me to get that error if there was no song in that location, so I coded I changed it to the following:

You probably want to handle events in the form the controls are in, not within the control itself. The form would have a reference to both controls and likely whatever they are controlling. That's where things should be connected.

You can achieve by wrapping FlexibleSpaceBar inside Container see code below

You can use Youtube Player Android SDK (https://developers.google.com/youtube/android/player/). That would be easier.

In your layout xml, add this:

It is because addItems is not a property but a method See Docs

You can assign on completion:

I have this model which holds the URL of the songs

The code that follows is not a model by any QML definition of the term.

Audio expects a Playlist element, it doesn't say anything about just about any models, even if you had one. Just because a Playlist can be used as a model doesn't necessarily mean any model can be used as a playlist. But even if that was possible, surely it would require a model with a source role, not an object with a source property.

What manager.getSongListByAlbumName() returns is at this point a mystery, so only a psychic would be able to answer the question as it is.

Assuming manager.getSongListByAlbumName() returns some sort of list that can be iterated from QML, you can use that to populate a Playlist by using the respective methods. I presume it will be possible to directly pass a QList to Playlist.addItems(sources) and just have it work as this particular container type is automatically converted for QML.
