如何使用Xamarin Intent过滤器接收URL

Question

我正在尝试使用Xamarin for Android编写一个简单的活动,可以共享URL(例如,Chrome可以共享我的活动的URL).

这是我到目前为止所得到的:

[Activity (Label = "LinkToDesktop", MainLauncher = true)]
[IntentFilter (new[] {
    Intent.ActionSend,
    Intent.CategoryBrowsable,
    Intent.CategoryDefault,
    })]

public class MainActivity : Activity
{
    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);
        string text = Intent.GetStringExtra ("MyData") ?? "Data not available";
    }
}

不幸的是,当我尝试分享时,我的应用不会显示在Chrome的列表中.我错过了什么？

编辑,更新我下面发布的代码.当我从Chrome分享时仍然没有显示为目标.

[Activity (Label = "LinkToDesktop", MainLauncher = true)]
    [IntentFilter (new[] { Intent.ActionSend }, 
    Categories = new[] { Intent.CategoryBrowsable, Intent.CategoryDefault })
]
public class MainActivity : Activity
    {
    protected override void OnCreate (Bundle bundle)
        {
        base.OnCreate (bundle);
        string text = Intent.GetStringExtra ("MyData") ?? "Data not available";
        }

    protected override void OnNewIntent (Intent intent)
        {
        base.OnNewIntent (intent);
        }
     }

Answer 1

弄清楚了.我缺少的主要部分是DataMimeType.

[Activity (Label = "LinkToDesktop", MainLauncher = true)]
[IntentFilter (new[] { Intent.ActionSend }, Categories = new[] {
    Intent.CategoryDefault,
    Intent.CategoryBrowsable
}, DataMimeType = "text/plain")]
public class MainActivity : Activity
    {
    protected override void OnCreate (Bundle bundle)
        {
        base.OnCreate (bundle);
        if (!String.IsNullOrEmpty (Intent.GetStringExtra (Intent.ExtraText)))
            {
            string subject = Intent.GetStringExtra (Intent.ExtraSubject) ?? "subject not available";
            Toast.MakeText (this, subject, ToastLength.Long).Show ();
            }
        }
    }
