无法解析引用Plugin.Permissions

Question

当在Plugin.Permissions中使用xamarin.forms时，我会得到这个错误：

无法解析引用: Plugin.Permissions，由MyProject引用。请为NuGet添加Plugin.Permissions包或程序集引用，或删除对MyProject的引用。MyProject.Android

但我在所有项目(表单、安卓、ios)中都添加了plugin.permission。

Answer 1

我在MainActivity中添加了这个方法：

public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Android.Content.PM.Permission[] grantResults)
    {
        PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode, permissions, grantResults);
        base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
    }

并在base.OnCreate(savedInstanceState)之后添加如下一行：

 protected override void OnCreate(Bundle savedInstanceState)
    {
        var intent = new Intent(this, typeof(MainService));
        StartService(intent);
        layout = FindViewById<LinearLayout>(Resource.Layout.AlertActivity);
        Log.Debug("StartService", "DemoService started");

        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;


        base.OnCreate(savedInstanceState);

        //this line added
        Plugin.CurrentActivity.CrossCurrentActivity.Current.Init(this,
savedInstanceState);

        Rg.Plugins.Popup.Popup.Init(this, savedInstanceState);
        global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
        LoadApplication(new App());
    }

现在一切都很好！谢谢你的帮助！
