标准意图URI坏了吗？

Question

我在特定设备上遇到意图URI问题,所以我尝试了CommonsWare URLHandler示例,如下所示:使用意图URI启动我的应用程序,其示例页面上的意图URI超链接也无法调用应用程序.该示例声明了其intent-filter,如下所示:

<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:

有人知道这里的意图URI是怎么回事吗？为什么不能工作？有解决方法吗？

谢谢,西蒙

由于我可以在HTC One S上复制这个问题,并且我不能在其他ICS/JB设备上复制这个问题,我认为这是HTC为响应Apple主导的诉讼而实施的Linkify工作方式的另一个结果.

有解决方法吗？

如果您控制双方(例如,WebView包含链接,加上响应intentURL 的应用程序),您可以通过手动强制选择器Intent.createChooser(),这可能会起作用.

但是,如果您依赖第三方代码(例如,Web浏览器)来打开您的应用程序,那么在这些HTC设备上,我相信您只是被搞砸了.
