This worked for me. Add this intent filter to your manifest file to make your application appear in the share list of the youtube application.

<intent-filter>
   <action android:name="android.intent.action.SEND" />
   <category android:name="android.intent.category.DEFAULT" />              
   <data android:host="www.youtube.com" android:mimeType="text/*" />
</intent-filter>
