Given that you can launch an installed android app using an NFC tag with a URL on it, using, e.g.:

<category android:name="android.intent.category.DEFAULT"/>
<data android:scheme="https"
          android:host="http://myurl.com"
          android:pathPrefix="/something" />

And that you can make that shorter using a url shortening service, or your own domain, and that redirects to the play store, why would you use an AAR on a tag? (Also, I believe the AAR intent wont pass data to the app).

I'm looking to make a tag that supports multiple OS, with as few bytes as possible - if I create a website that has links to each phone's store, what advantage is there to including an AAR or LaunchApp record on the tag?

为什么要在标签上使用 AAR？

因为您的（原始的、预编辑的）建议的 URL 会导致标签始终进入 Play 商店。AAR 旨在仅在设备上没有可以处理主要 NFC 记录的应用程序时进入Play 商店。有关更多信息，请参阅我对我自己的问题的回答。

您的使用方法http://myurl.com/something应该可以正常工作，只要：

  • 该标签应该只对您的应用有效

  • 设备上没有其他任何东西宣传对该特定主机和路径前缀的支持
