Android Development – Add new application for gene’s own “share vCalendar”

I’m trying to add own application to Calendar “share via” menu, by adding intent filter to
manifest.xml:

<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <action android:name="android.intent.action.SENDTO" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="text/x-vCalendar" />
</intent-filter>

It works fine on Samsung phones, but not on HTC.
What do I need to do to make it work on HTC phone?

Thanks
