Windows Phone 8.1：如何从我的应用启动已安装的应用

Question

我试过以下链接

How do I launch other app from my own app in Windows Phone 8.1?

Call an external app on windows phone 8.1 runtime(not silverlight) xaml c# application

但对我来说没有任何用处，因为我只是想启动一个应用程序，例如单击按钮从我的应用程序中获取愤怒的小鸟。

请帮忙

Answer 1

如果应用有a registered URI, then you should be able to use Launcher.LaunchUriAsync for this. You can also find some help, here at MSDN - How to launch the default app for a URI.

不然我觉得不可能

Answer 2

对我有用。

设置从其他应用程序启动的应用程序。

在 < /token> 和之间的 WMAppManifest.xaml 中添加这个

<Extensions>
   <Protocol Name="alsdkcs" NavUriFragment="encodedLaunchUri=%s" TaskID="_default" />
</Extensions>

添加一个 class "AssociationUriMapper " 并覆盖函数 "MapUri()"

class AssociationUriMapper : UriMapperBase{
   private string tempUri;

   public override Uri MapUri(Uri uri){
      tempUri = System.Net.HttpUtility.UrlDecode(uri.ToString());
      if (tempUri.Contains("alsdkcs:MainPage?id=")){
         int idIndex = tempUri.IndexOf("id=") + 3; //3 is the length of "id="           
         string id = tempUri.Substring(idIndex);

         return new Uri("/MainPage.xaml?id=" + id, UriKind.Relative);
     }
     return uri;
  }
}

并在 InitializePhoneApplication() 函数的这一部分从其他 app.xaml.cs 调用它们

RootFrame.UriMapper = new AssociationUriMapper(); // add this line only between RootFrame.Navigated += CompleteInitializePhoneApplication; and RootFrame.NavigationFailed += RootFrame_NavigationFailed;

终于从其他应用程序调用以启动应用程序

var success = await Windows.System.Launcher.LaunchUriAsync(new System.Uri("alsdkcs:MainPage?id="+5)); 
if (success){
   // URI launched
}
else{
  // URI launch failed
}

其中 "alsdkcs" 是协议名称。
