How to get Device and App Informations in MAUI

As a mobile apps developer, sometimes we need device and app information like device Model, Manufacturer, OS Version, App Version, Package Name etc. to perform some actions. That’s why in this article i am going to show you how to get device and app Informations in MAUI.

Let’s Start

In this article you will see :

• What is DeviceInfo?
• What is AppInfo?

What is DeviceInfo?

• DeviceInfo is a class in MAUI that allows us to get device information on which our App is running on.

Device information that we can get using DeviceInfo class : 

• Model – It provides us device model. (eg : iPhone13)
• Manufacturer – It provides us device Manufacturer. (eg : Apple)
• Name – It provides us device name. (eg : Alamgeer’s iPhone)
• VersionString -It provides us os version. (eg : 16.2)
• Idiom – It provides us types of device on which the application is running on. It can be Phone, Tablet, Desktop, TV, Watch etc.
• Platform – It provides us device platform. It can be Android, iOS, WinUI, MacCatalyst, Tizen etc.
• DeviceType – It provides us types of device and identify if we are running the application on an emulator or physical device.

What is AppInfo?

• AppInfo is a class in MAUI that allows us to get app Information.

App information that we can get using AppInfo class : 

• Name – It provides us name of the application. (eg : MAUIDeviceAndAppInfoSample)
• PackageName – It provides us package name or identifier of the application. (eg : com.companyname.mauideviceandappinfosample)
• VersionString – It provides us the application version. (eg : 1.0)
• BuildString – It provides us the build number of the version. (eg : 1)
• RequestedLayoutDirection – It provides the current requested layout direction. (eg : LeftToRight)
• RequestedTheme – It provides the current requested theme by the system for your application. (eg : Light)

Let’s move to the coding part !!

Setting up the UI

1 – Create a MainPage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage
    x:Class="MAUIDeviceAndAppInfoSample.MainPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    BackgroundColor="Black">

    <ScrollView>
        <VerticalStackLayout
            Padding="20"
            BackgroundColor="White"
            Spacing="10">

            <Label
                FontAttributes="Bold"
                FontSize="22"
                Text="Device Informtaion" />

            <Label x:Name="LblDeviceInfo" FontSize="18" />

            <Label
                FontAttributes="Bold"
                FontSize="22"
                Text="App Informtaion" />

            <Label x:Name="LblAppInfo" FontSize="18" />

        </VerticalStackLayout>
    </ScrollView>

</ContentPage>

2 – MainPage.xaml.cs

using System.Text;

namespace MAUIDeviceAndAppInfoSample;

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        LblDeviceInfo.Text = GetDeviceInfo();
        LblAppInfo.Text = GetAppInfo();
    }

    private string GetDeviceInfo()
    {
        return new StringBuilder()
            .AppendLine($"Model : {DeviceInfo.Current.Model}")
            .AppendLine($"Manufacturer : {DeviceInfo.Current.Manufacturer}")
            .AppendLine($"Name : {DeviceInfo.Name}")
            .AppendLine($"OS Version : {DeviceInfo.VersionString}")
            .AppendLine($"Refresh Rate : {DeviceInfo.Current}")
            .AppendLine($"Idiom : {DeviceInfo.Current.Idiom}")
            .AppendLine($"Platform : {DeviceInfo.Current.Platform}")
            .AppendLine($"Device Type : {DeviceInfo.Current.DeviceType}").ToString();
    }

    private string GetAppInfo()
    {
        return new StringBuilder()
           .AppendLine($"Name : {AppInfo.Current.Name}")
           .AppendLine($"Package : {AppInfo.Current.PackageName}")
           .AppendLine($"Version : {AppInfo.Current.VersionString}")
           .AppendLine($"Build : {AppInfo.Current.BuildString}")
           .AppendLine($"LayoutDirection : {AppInfo.RequestedLayoutDirection}")
           .AppendLine($"Theme : {AppInfo.RequestedTheme}").ToString();
    }
}

That’s all for now!
