valueNotifier.value doesn't change

[ajsatam]

Hi @siddhesh-tamhanekar
I have created an event listener like below to capture index change when playing a playlist. But whenever the event listener fires it only throws an initial value it never gives an updated value. Below is my function.

void initAudio() async {

    player = MediaPlayerPlugin.create(isBackground: true, showNotification: true);
    await player.initialize();

    player.valueNotifier.addListener(() {

      this.currentPlaylistIndex = player.valueNotifier.value.currentIndex;
      print("state changed:"+player.valueNotifier.value.duration.toString());

      print("state changed:"+player.valueNotifier.value.currentIndex.toString());


      setState(()
      {

      });
    });


    await player.setPlaylist(Playlist(playlist));
    player.play();

    setState(() {
       audioState = 1;
    });
  }
}

Hi @ajsatam I have used the media player at multiple applications I didn't come across such error

You can look at the sample application https://github.com/siddhesh-tamhanekar/podcastApp
which demonstrates building duration widgets and playlist etc.

Your code looks okay at first glance but needs to debug about what is going wrong can you share more details such as your device, android version and useful debugging information.

meanwhile, you can try to install the podcast app given above and try if it works fine on the device.

Hopefully, This will help you to solve your problem
All the best.

Hi @siddhesh-tamhanekar I checked the project. Downloaded the apk on One Plus six and One plus 7 pro and it's the same. While the podcast changes but the name of the podcast and selected podcast in the list view below remains the same. It doesn't change.

Below is the device information:
Name: One Plus six, One plus 7 Pro
Android version : 9
OxygenOS version : 9.0.7

Please let me know if you need any more information.

HI @ajsatam I have checked for android version:9 (pie) on the emulator and it works perfectly maybe there is a problem with OxygenOS

Unfortunately, I didn't have Oneplus device so couldn't able to debug.

will you please provide debug log message which could reveal the information

Also checked on the below device but the same issue

Name : Lenovo K50
Android version : 5.0

[siddhesh-tamhanekar]

@ajsatam I don't have either 5.0 version device.
You could share logs here to get some clue.

I'm a bit new to Android studio but it's the same which you get in the Console window right? Here it is. Please let me know otherwise.
