I'm messing around with some tags (Mifare classic)
I have written with the nxp application tagwriter an message in plaintext to the tag.
the following code is what I have so far:
** Called when a new nfc interaction/intent is fired */
public void onNewIntent(Intent intent) {
NdefMessage[] msgs = null;
if(intent.equals(NfcAdapter.ACTION_NDEF_DISCOVERED)){
Parcelable[] rawMsgs = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
if(rawMsgs!=null){
msgs = new NdefMessage[rawMsgs.length];
for(int i=0;i<rawMsgs.length;i++){
msgs[i] = (NdefMessage) rawMsgs[i];
}
}
} else {
Log.e(TAG, "Other intent then NDEF_DISCOVERED");
}
I dont know where to go one from this point, can someone point me in the right direction?
I want to read the value inside these messages, I already know that a ndefmessage contains ndefrecords, but how can i determine which record is the record i need?
A simple example for the first record of the first message:
NdefRecord[] recs = msgs[0].getRecords();
byte[] type = recs[0].getType();
byte[] value = recs[0].getPayload();
When you know the type, you may be able to interpret the value
bytes.
