RegisterNavigationServiceAppStart期间的MvxIoCResolveException

【RegisterNavigationServiceAppStart期间的MvxIoCResolveException】金鞍玉勒寻芳客，未信我庐别有春。这篇文章主要讲述RegisterNavigationServiceAppStart期间的MvxIoCResolveException相关的知识，希望能为你提供帮助。
在调用RegisterNavigationServiceAppStart期间，我得到异常：MvvmCross.Platform.Exceptions.MvxIoCResolveException：找不到类型MvvmCross.Core.ViewModels.MvxNavigationServiceAppStart的构造函数失败在调试期间一切正常。但是当我构建版本并准备一个apk时，我得到了这个例外。下面我从设备监视器粘贴日志：

你能告诉我我做错了什么吗？
答案确保你的android项目中有一个文件LinkerPleaseInclude.cs与this content：

using System; using System.Collections.Specialized; using System.Windows.Input; using Android.App; using Android.Views; using Android.Widget; using MvvmCross.Binding.BindingContext; using MvvmCross.Core.Navigation; using MvvmCross.Core.ViewModels; namespace MyNamespace { // This class is never actually executed, but when Xamarin linking is enabled it does how to ensure types and properties // are preserved in the deployed app public class LinkerPleaseInclude { public void Include(Button button) { button.Click += (s,e) => button.Text = button.Text + ""; }public void Include(CheckBox checkBox) { checkBox.CheckedChange += (sender, args) => checkBox.Checked = !checkBox.Checked; }public void Include(Switch @switch) { @switch.CheckedChange += (sender, args) => @switch.Checked = !@switch.Checked; }public void Include(View view) { view.Click += (s, e) => view.ContentDescription = view.ContentDescription + ""; }public void Include(TextView text) { text.AfterTextChanged += (sender, args) => text.Text = "" + text.Text; text.Hint = "" + text.Hint; }public void Include(CheckedTextView text) { text.AfterTextChanged += (sender, args) => text.Text = "" + text.Text; text.Hint = "" + text.Hint; }public void Include(CompoundButton cb) { cb.CheckedChange += (sender, args) => cb.Checked = !cb.Checked; }public void Include(SeekBar sb) { sb.ProgressChanged += (sender, args) => sb.Progress = sb.Progress + 1; }public void Include(RadioGroup radioGroup) { radioGroup.CheckedChange += (sender, args) => radioGroup.Check(args.CheckedId); }public void Include(RadioButton radioButton) { radioButton.CheckedChange += (sender, args) => radioButton.Checked = args.IsChecked; }public void Include(RatingBar ratingBar) { ratingBar.RatingBarChange += (sender, args) => ratingBar.Rating = 0 + ratingBar.Rating; }public void Include(Activity act) { act.Title = act.Title + ""; }public void Include(INotifyCollectionChanged changed) { changed.CollectionChanged += (s,e) => { var test = $"{e.Action}{e.NewItems}{e.NewStartingIndex}{e.OldItems}{e.OldStartingIndex}"; }; } public void Include(ICommand command) { command.CanExecuteChanged += (s, e) => { if (command.CanExecute(null)) command.Execute(null); }; }public void Include(MvvmCross.Platform.IoC.MvxPropertyInjector injector) { injector = new MvvmCross.Platform.IoC.MvxPropertyInjector (); } public void Include(System.ComponentModel.INotifyPropertyChanged changed) { changed.PropertyChanged += (sender, e) => { var test = e.PropertyName; }; }public void Include(MvxTaskBasedBindingContext context) { context.Dispose(); var context2 = new MvxTaskBasedBindingContext(); context2.Dispose(); } public void Include(MvxNavigationService service, IMvxViewModelLoader loader) { service = new MvxNavigationService(null, loader); } public void Include(ConsoleColor color) { Console.Write(""); Console.WriteLine(""); color = Console.ForegroundColor; Console.ForegroundColor = ConsoleColor.Red; Console.ForegroundColor = ConsoleColor.Yellow; Console.ForegroundColor = ConsoleColor.Magenta; Console.ForegroundColor = ConsoleColor.White; Console.ForegroundColor = ConsoleColor.Gray; Console.ForegroundColor = ConsoleColor.DarkGray; } } }

它将确保链接器不会剥离MvvmCross工作所需的类，属性等。这就是可能发生的事情
