Question

How to turn on/off airplane mode in Xamarin.Forms for android and ios?

Answer 1

As @Patrick Hofman and @DavidG said.You could not turn on/off airplane mode by code in your project . However , you can open the setting page of system in Forms by using Dependency Service and let user turn on/off airplane mode manual.

in Forms,add a new interface

public interface ISettingsService
{
  void OpenSettings();
}

in iOS

using xxx.iOS;
using Foundation;
using UIKit;
using Xamarin.Forms;

[assembly: Dependency(typeof(OpenSettingsImplement))]
namespace xxx.iOS
{
    public class OpenSettingsImplement : ISettingsService
    {
        public void OpenSettings()
        {
            var url = new NSUrl($"App-Prefs:");
            UIApplication.SharedApplication.OpenUrl(url);
        }
    }
}

Note:

App-Prefs: is private api in iOS. So if you want to upload it to app store , it will may been rejected by the store .

in Android

using Android.Content;

using xxx;
using xxx.Droid;
using Xamarin.Forms;

[assembly: Dependency(typeof(OpenSettingsImplement))]
namespace xxx.Droid
{
    public class OpenSettingsImplement : ISettingsService
    {
        public void OpenSettings()
        {
            Intent intentOpenSettings = new Intent();
            intentOpenSettings.SetAction(Android.Provider.Settings.ActionAirplaneModeSettings);
            Android.App.Application.Context.StartActivity(intentOpenSettings);
        }
    }
}
