Why do you need to default key with 00 bytes?
I don't understand the "format" logic. Why not just "setting" the key?
My initializeLibrary method works:

        KeyStoreFactory.KeyStoreType kst = libInstance.getKeyStoreType();



        try {



            IKeyStore iks= libInstance.getKeyStore();



            ks = KeyStoreFactory.getInstance().getSoftwareKeyStore();



            ks.formatKeyEntry(0,IKeyConstants.KeyType.KEYSTORE_KEY_TYPE_AES128);

            ks.setKey(0, (byte) 0, IKeyConstants.KeyType.KEYSTORE_KEY_TYPE_AES128, DEFAULT_KEY_AES128);



            ks.formatKeyEntry(1, IKeyConstants.KeyType.KEYSTORE_KEY_TYPE_AES128);

            ks.setKey(1, (byte) 0,

                   IKeyConstants.KeyType.KEYSTORE_KEY_TYPE_AES128, KEY_CASHLESSCODE_APP);





        } catch (SmartCardException e) {

            showMessage(e.getMessage(), 'l');

            showMessage("SmartCardException in init Keystore ... check LogCat",

                    't');

            e.printStackTrace();

        }

        libInstance.loadKeyStore(ks);

But not my desfireEV1CardLogic:

        int keyNo = 1;

        byte version = 0;



        int[] appids;



        try {



            DESFireEV1.CardDetails details =  objDESFireEV1.getCardDetails();

            TextView txtUid = (TextView) findViewById(R.id.txtUid);

            txtUid.setText(Utilities.dumpBytesAscii(details.uid));



            //appids = objDESFireEV1.getApplicationIDs();



            objDESFireEV1.selectApplication(131072);

// OK



            byte[] dataCustomerCode = new byte[13];



            dataCustomerCode = objDESFireEV1.readData(1, 0, dataCustomerCode.length, DESFireEV1.CommunicationType.Plain);

			// OK for the plain data in this app !



            TextView txtCustomerCode = (TextView) findViewById(R.id.txtCustomerCode);

            txtCustomerCode.setText(Utilities.dumpBytesAscii(dataCustomerCode));



            byte[] dataCashlessCode = new byte[12];



            objDESFireEV1.selectApplication(65536);

			// select the other app: OK



            objDESFireEV1.authenticate(DESFireEV1.AuthType.AES, keyNo, version, 0, (byte) 0, null);

			//

			// authenticate KO !

			//



            dataCashlessCode = objDESFireEV1.readData(1, 0, dataCashlessCode.length, DESFireEV1.CommunicationType.Enciphered);





        } catch (IOException e) {

            e.printStackTrace();

        } catch (DESFireException e) {

            e.printStackTrace();

        } catch (GeneralSecurityException e) {

            e.printStackTrace();

        } catch (SmartCardException e) {

            e.printStackTrace();

        }
