krumelur / volumeslider Goto Github PK

Hi, I have got the following error "Cannot access a disposed object.Object name: 'VolumeSliderPlugin.Droid.VolumeSliderRenderer'."

Reproduce:
1.Access the page that have implemented VolumeSlider and tried to adjust the volume at this time it is working perfectly.
2.After that left the page and go back to adjust the volume now you will get an error.

Here is the full error stack :

System.ObjectDisposedException: Cannot access a disposed object.

How to solve this issue?

Thank you in advance.

I cannot seem to find a way to change the volume via code. Whatever volume I set in the code only takes effect when a user interacts with the volume slider.

<StackLayout>
    <!-- Place new controls here -->
    <Button Text="Siren!" 
       HorizontalOptions="Center"
       VerticalOptions="CenterAndExpand"
       Clicked="SirenBtnClicked">
    </Button>
    <vs:VolumeSlider x:Name="volumeSlider" Volume="0.5" WidthRequest="300" HorizontalOptions="Center"/>
</StackLayout>

private void SirenBtnClicked(object sender, EventArgs e)
{

        if (!audioPlayer.IsPlaying) {

            audioPlayer.Play();
            volumeSlider.SetValue(VolumeSlider.VolumeProperty, 1);
        }
        else
        {
            audioPlayer.Stop();
        }
        
    }
