Is it working with Desfire EV1 too?

Ok. I've just tried with a Samsung S4 Mini with Android 4.4.2 and it doesn't work.
So I've downloaded an app from the playstore to test if i could connect with the DESFire EV1 card. I put the right key but it always give me "Authentication failed", so I definitely think there should be some troubles with our devices. I'd be curious to try with another device brand..

What error do you get?

As actually I only need to read the ID card, I've written my code to take it from the intent. I know it's not a solution to this problem, but it's a solution to my personal problem :)
Anyway, if I'll find a complete solution I'll post it here.
Thanks for your time!

If I change the "0" it gives me "invalidResponse: No Such Key"

No, mine is not rooted, too. This error is so strange because happens always with "0", independently from others parameters.

Always the same error. Too weird. Could it be the phone? I'm using a Samsung S4 with Android Lollipop

I will do it in a couple of minutes, but if it can be useful, I've just tried to use the sample app edited with my key and it gives me the same error with the "0"

I've tried something like this

@Override

            public void onDESFireCardDetected(DESFire desFire) {

                super.onDESFireCardDetected(desFire);

                try {

                    try {

                        desFire.connectL4();

                    } catch (IOException e) {

                        e.printStackTrace();

                        Log.d("TAG", "Problem with connection");

                    }

                    try {

                        desFire.authenticate(DESFire.AuthType.Native, 0, (byte) 0, 0, (byte) 0, null);

                    } catch (IOException e) {

                        e.printStackTrace();

                        Log.d("TAG", "Problem with authentication");

                    }

                    Log.d("TAG", "Checking if auth succesfull");



                    byte[] UID = desFire.getCardUID();

                    String rfid = com.nxp.nfclib.utils.Utilities.dumpBytes(UID);



                    desFire.closeL4();



                    Toast.makeText(context, "DESFire UID: " + rfid, Toast.LENGTH_SHORT).show();



                } catch (DESFireException e) {

                    e.printStackTrace();

                    Toast.makeText(context, "Authentication failed.", Toast.LENGTH_SHORT).show();

                } catch (SmartCardException e) {

                    e.printStackTrace();

                } catch (GeneralSecurityException e) {

                    e.printStackTrace();

                } catch (IOException e) {

                    e.printStackTrace();

                }

            }

And it gives me "Problem with authentication"

No, I'm not. I've tried lots of times (always without removing the card) and it gives me the same error.

I'm not using

format()

method and I can't see the logcat message of successfully authentication.

So, I've also tried so remove the

close()

method but it didn't change anything, because the problem is before.

I don't know why, but if I make this change i catch into "android.nfc.TagLostException: Tag was lost." exception.
