我在特定设备上遇到了 Intent URI 的问题，所以我按照此处的建议尝试了 CommonsWare URLHandler 示例:Launching my app using the intent URI ，并且其示例页面上的 Intent URI 超链接也无法调用该应用程序。该示例声明其 intent-filter 如下:

<intent-filter>
    <action android:name="com.commonsware.android.MY_ACTION" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

示例网页中的超链接是:

<a href="intent:#Intent;action=com.commonsware.android.MY_ACTION;end">Link back to URLHandler via intent: URL</a>

这适用于大多数设备，但不适用于运行 Android 4.0.3 的 HTC Amaze 4G。当我触摸链接时，logcat 给出:

有人知道这里的 Intent URI 是怎么回事吗？为什么它无法工作？有解决方法吗？

谢谢， 西蒙

最佳答案

因为我可以在 HTC One S 上重现这个问题，而我不能在其他 ICS/JB 设备上重现这个问题，我认为这是 Linkify 解决方法的另一个结果 HTC put in place in response to Apple-led litigation .

And is there a workaround?

如果您控制双方(例如，包含链接的 WebView，以及响应 intent URL 的应用)，您可以手动强制选择器通过 Intent.createChooser()，这可能有效。

但是，如果您依靠第三方代码(例如 Web 浏览器)来打开您的应用程序，那么我相信您在这些 HTC 设备上就完蛋了。
