how i can grant permission WRITE_SETTINGS in the app

Question

var bi = Settings.System.CanWrite(Android.App.Application.Context);
                        if (bi)
                        {
                            Console.WriteLine("IT HAS PERMISIONS`enter code here`");
                        }
                        else
                        {
                            Intent intent = new Intent(Android.Provider.Settings.ActionManageWriteSettings);
                            intent.SetData(Android.Net.Uri.Parse("package:" + Android.App.Application.Context.PackageName));
                            StartActivity(intent);
                            Console.WriteLine("doesnt have permisions");
                        }

i get obviously direct in else execution block, but intent get null what is the problem? how i can grant permissions for write settings? i use xamarin with c# for android mobile AND ALREADY INSERT TO MANIFEST <uses-permission android:name="android.permission.WRITE_SETTINGS" />

Answer 1

Intent intent = new Intent(Settings.ActionManageWriteSettings);
intent.SetData(Android.Net.Uri.Parse($"package:{Android.App.Application.Context.PackageName}"));
intent.AddFlags(ActivityFlags.NewTask);
Android.App.Application.Context.StartActivity(intent);

in the end work with the code above
