Hallo Domnic, > My resource file looks like > <resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2"> > <tech-list> > <tech>android.nfc.tech.NfcA</tech> > <tech>android.nfc.tech.NfcB</tech> > <tech>android.nfc.tech.NfcF</tech> > <tech>android.nfc.tech.NfcV</tech> > <tech>android.nfc.tech.Ndef</tech> > <tech>android.nfc.tech.NdefFormatable</tech> > <tech>android.nfc.tech.MifareClassic</tech> > </tech-list> > </resources>
Right, this tech-list won't trigger on any tag. Take a look at the documentation at [url]http://developer.android.com/reference/android/ nfc/NfcAdapter.html#ACTION_TECH_DISCOVERED[/url]. It says that <tech- list> combines its <tech> entries with AND. So you are trying to listen for a tag that is NfcA AND NfcB AND NfcF AND NfcV at the same time. However a tag will only be detected as one RF technology. To listen for multiple tag technologies you would need multiple <tech- list> entries (they are then combined with logical OR.) If you want to detect only MIFARE Classic, a filter like this would suffice: <resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2"> <tech-list> <tech>android.nfc.tech.MifareClassic</tech> </tech-list> </resources> Of course every MIFARE tag uses the RF technology NfcA, so a filter like this will also work: <resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2"> <tech-list> <tech>android.nfc.tech.NfcA</tech> <tech>android.nfc.tech.MifareClassic</tech> </tech-list> </resources> br, Michael -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
