標準意圖URI破碎了嗎？

Question

我在特定設備上的意圖URI存在問題，所以我嘗試了CommonsWare URLHandler示例，如下所示：Launching my app using the intent URI，並且其示例頁面上的意向URI超鏈接也無法調用該應用程序。此示例聲明其意圖過濾器是這樣的：

<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> 

而且在樣品網頁中的超鏈接是：

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

這適用於大多數設備，但不是在HTC驚奇4G，運行Android 4.0.3。當我觸摸鏈接時，logcat會給出：

有人知道這裏有意圖URI嗎？爲什麼它沒有工作？是否有解決方法？

感謝， 西蒙

因爲我可以在一個HTC個S複製這個問題，我不能複製在其他ICS/JB設備這個問題，我相信這是Linkify變通方法，HTC put in place in response to Apple-led litigation的又一成果。

是否有解決方法？

如果你在兩邊（例如，含有WebView的聯繫，再加上應用程序響應intent URL）的控制，你可以通過手動Intent.createChooser()強制選擇器，以及可能的工作。

但是，如果您依賴第三方代碼（例如Web瀏覽器）來打開您的應用程序，那麼在這些HTC設備上，我相信您只是被搞砸了。
