Thanks for your help. In the definition of the intent-filter I cannot use the android:path part as this one matches only if it is an exact match, i.e. in the above example only if the tag contains the URL http://commonsware.com/nfctest. It is not possible to add wildcards in the path part. But somewhere I have to add the tag specific data!
The solution is to ommit the path part and to define a special host (e.g. android:host="nfctest.commonsware.com".
