Plugin.Maui.Pedometer

Plugin.Maui.Pedometer provides the ability to read the device pedometer in your .NET MAUI application. This plugin currently only supports iOS and Android.

Install Plugin

Available on NuGet.

Install with the dotnet CLI: dotnet add package Plugin.Maui.Pedometer, or through the NuGet Package Manager in Visual Studio.

API Usage

Plugin.Maui.Pedometer provides the Pedometer class that can be used to monitor the device pedometer and track the user's step count.

Permissions

Before you can start reading pedometer values, you will need to request the proper permissions on each platform.

iOS

On iOS, add the NSMotionUsageDescription key to your info.plist file. When declared, the permission will be requested automatically at runtime.

<key>NSMotionUsageDescription</key>
<string>This app wants to track your pedometer readings</string>

Android

On Android with API 29+, declare the ACTIVITY_RECOGNITION permissions in your AndroidManifest.xml file. This should be placed in the manifest node. You can also add this through the visual editor in Visual Studio.

The runtime permission is automatically requested by the plugin when Start() is called.

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />

Dependency Injection

You will first need to register the Pedometer with the MauiAppBuilder following the same pattern that the .NET MAUI Essentials libraries follow.

builder.Services.AddSingleton(Pedometer.Default);

You can then enable your classes to depend on IPedometer as per the following example.

public class StepCounterViewModel
{
    readonly IPedometer pedometer;

    public StepCounterViewModel(IPedometer pedometer)
    {
        this.pedometer = pedometer;
    }

    public void StartCounting()
    {
        pedometer.ReadingChanged += (sender, reading) =>
        {
            Console.WriteLine(reading.NumberOfSteps);
        };

        pedometer.Start();
    }
}

Straight usage

Alternatively if you want to skip using the dependency injection approach you can use the Pedometer.Default property.

public class StepCounterViewModel
{
    public void StartCounting()
    {
        pedometer.ReadingChanged += (sender, reading) =>
        {
            Console.WriteLine(reading.NumberOfSteps);
        };

        Pedometer.Default.Start();
    }
}

Properties

IsSupported

Gets a value indicating whether reading the pedometer is supported on this device.

IsMonitoring

Gets a value indicating whether the pedometer is actively being monitored.

Methods
