How can I automatically launch an application when touching an RFID tag?
Nokia 6131 NFC supports the JSR-257 PushRegistry connections as defined in JSR-257 specification 1.0 Appendix B. You can download this from the Java Community Process site – it contains a lot of useful information about PushRegistry (NDEF record push, Secure Element push, possible URLs for NDEF record push, etc.) Briefly – if a MIDlet is launched by touching an NDEF tag and an NDEFRecordListener is registered to DiscoveryManager using the appropriate NDEF record type within thirty seconds of getting the DiscoveryManager instance, then the listener will be notified and the recordDetected() parameter will contain the NDEF record that triggered the launch. In order to launch the MIDlet by touching a tag and also get the information on the tag after the MIDlet has been launched, you must implement NDEFRecordListener and its method recordDetected and also, in the constructor, add the NDEFRecordListener to the DiscoveryManager with the corresponding NDEFRecordType.
