Volume control on Android devices via buttons

[LukasFis]

Hi, I need some advice please. I need to create a simple application that allows control over the "Volume up" and "Volume down" buttons on the display of an Android device by pressing the device's volume. I couldn't find instructions for this application, so I'll try to ask you.

Thanks for all the advice.

MainPage.xaml.cs:

`using Microsoft.Maui.Devices;
using Microsoft.Maui.Controls;
using Android.Media;
using Android.Content;
using Microsoft.Maui.Controls.Xaml;
using Microsoft.Maui.Essentials;
using Microsoft.Maui;

namespace device;
public partial class MainPage : ContentPage
{

public MainPage()
{
	InitializeComponent();
}

private void VolumeUp(object sender, EventArgs e)
{
   

}

private void VolumeDown(object sender, EventArgs e)
{
    
}

private void RozsvititBaterku(object sender, EventArgs e)
{
    Flashlight.TurnOnAsync();
}

private void ZhasnoutBaterku(object sender, EventArgs e)
{
    Flashlight.TurnOffAsync();
}

private void ZapnoutVibraci(object sender, EventArgs e)
{
    int cas = 5;
    TimeSpan casovac = TimeSpan.FromSeconds(cas);
    Vibration.Default.Vibrate(casovac);
}

private void VypnoutVibraci(object sender, EventArgs e)
{
    Vibration.Default.Cancel();
}

}

MainPage.xaml:

`

<ScrollView>
    <VerticalStackLayout
        VerticalOptions="Center">

        <Button Text="Volume Up" Clicked="VolumeUp" Margin="10"/>
        <Button Text="Volume Down" Clicked="VolumeDown" Margin="10"/>
        <Button Text="Rozsvítit baterku" Clicked="RozsvititBaterku" Margin="10"/>
        <Button Text="Zhasnout baterku" Clicked="ZhasnoutBaterku" Margin="10"/>
        <Button Text="Zapnout vibraci" Clicked="ZapnoutVibraci" Margin="10"/>
        <Button Text="Vypnout vibraci" Clicked="VypnoutVibraci" Margin="10"/>

    </VerticalStackLayout>
</ScrollView>
