There is nothing in Xamarin Forms which will help you - Xamarin Forms is a graphical user interface.

You need to write custom code to use the sound APIs on each target operating system.
Xamarin's iOS wrapper and Xamarin's Android wrapper both give you access in C# to the iOS and Android audio APIs where you can detect what audio hardware there is and initialise the microphone.

The two APIs are very different but both will give you raw PCM in stereo or mono with the usual sample rates (8k, 16k, 32k 44.1 and 48k) and 8 or 16 bit samples

I would probably use an integer (or maybe double) for the TimeSpent property - you can easily convert TimeSpan to/from miliseconds or ticks.
And the color can be saved as a hex code represented as string, eg. #ff0000 for red. You can use Color.FromHex then after loading the value from database. It can be an integer too.

@Demond As what @JiriMatejka said usually we store int or double for Timespan and use hex sting for Color storing in database.
You can convert the Color to hex string like:

var color = Xamarin.Forms.Color.Red;
int red = (int)(color.R * 255);
int green = (int)(color.G * 255);
int blue = (int)(color.B * 255);
int alpha = (int)(color.A * 255);
string hex = $"#{alpha:X2}{red:X2}{green:X2}{blue:X2}";

And easily consume this string use Color.FromHex(hex);.

Hello
Welcome !

Your problem is that your cell has a bindingContext set to the model associated. You don't have a AddProgressCommand in your SurfBoard view model.

There is 2 options : either you add the command in your model or you change the binding source of your button's command to target a control outside the data template (for instance, your listView).

Try that :
<TapGestureRecognizer NumberOfTapsRequired="2" Command="{Binding BindingContext.AddProgressCommand, Source={x:Reference listView}}"/>

If you are beginning, may I suggest you to download and use XamlStyler ? It's an awesome plugin to format your XAML. Another thing, it's just a matter of fashion but if I was you, I would name my private field like this :
string icon; ====> private string _icon.
Why ? Because if inside a method you want to add a local var with a name like icon, you will need to say this.icon to access to your field. Once you start prefixing your var with this, you end up prefixing all the things with this
I had the same habit as you and it hurts a lot when working with other people who doesn't like to prefix things with this or to prefix private fields with an underscore.

Have a good luck in your development !

When you declare service AccessibilityService in Xamarin Android , you could try the following way :

[Service(Label = "myApp", Permission = Manifest.Permission.BindAccessibilityService)]
[IntentFilter(new[] { "android.accessibilityservice.AccessibilityService" })]
[MetaData("android.accessibilityservice.AccessibilityService", Resource = "@xml/my_accessibility_service")]
public class MyAccessibilityService : AccessibilityService
{
    public override void OnAccessibilityEvent(AccessibilityEvent e)
    {
        //......
    }
    public override void OnInterrupt()
    {
        throw new NotImplementedException();
    }
    protected override void OnServiceConnected()
    {

    }
}

And there is a demo in the attachment you can refer to.

It's a know issue in native Android:

• Tabs don't fit to screen with tabmode=scrollable, Even with a Custom Tab Layout
• TabLayout not filling width when tabMode set to 'scrollable'

Here is a workaround:

Create you own TabLayout:

public class CustomTabLayout : TabLayout
    {
        public CustomTabLayout(Context context) : base(context) { }

        public CustomTabLayout(Context context, IAttributeSet attrs) : base(context, attrs) { }

        public CustomTabLayout(Context context, IAttributeSet attrs, int defStyleAttr) : base(context, attrs, defStyleAttr) { }

        protected override void OnMeasure(int widthMeasureSpec, int heightMeasureSpec)
        {
            base.OnMeasure(widthMeasureSpec, heightMeasureSpec);
            try
            {
                if (TabCount == 0)
                    return;

                ViewGroup tabLayout = (ViewGroup)GetChildAt(0);

                int childCount = tabLayout.ChildCount;

                int[] widths = new int[childCount + 1];

                for (int i = 0; i < childCount; i++)
                {
                    widths[i] = tabLayout.GetChildAt(i).MeasuredWidth;
                    widths[childCount] += widths[i];
                }

                int measuredWidth = MeasuredWidth;
                for (int i = 0; i < childCount; i++)
                {
                    tabLayout.GetChildAt(i).SetMinimumWidth(measuredWidth * widths[i] / widths[childCount]);
                }
            }
            catch (Exception e)
            {
                e.ToString();
            }
        }
    }

Place it in your Android project Resources\layout\Tabbar.xml:

<?xml version="1.0" encoding="utf-8"?>
<namespace.CustomTabLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/sliding_tabs"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:tabIndicatorColor="@android:color/white"
    app:tabGravity="fill"
    app:tabMode="scrollable" />

More details is needed. What type of class is your LoginPage?
