[android-developers] NFC Secure Element by Software

2012-09-10 Thread Gorka 
Hi all,

I would like to know which are the solutions that nowadays are being 
proposed in order to develop software-based secure elements. I know what a 
Secure Element is, so please don´t tell me that the Secure Element must be 
a hardware device by definition and that it could be an UICC/SIM or an 
embeded device such as the one Google devices have nowadays. I have just 
begun to deepen on mobile transaction issues and, considering that SWP and 
card emulation are not supported by default (solutions that require rooting 
the device are not feasible for the kind of things I want to do), software 
based secure elements is the solution I should use.

By secure element I mean any software development that allow users to 
perform cryptographic operations safely: how to store data safely on my 
device, software related to One Time Passwords (OTP) that are usually used 
on banking operations, certificates, etc.

Any document, tutorial, application that you could suggest me would be 
really appreciated.

Thanks a lot, and regards.

[android-developers] Re: does NFC in gingerbread support card simulate?

2012-05-17 Thread Gorka 
Hi Shailen,

I guess you have emulated your MIFARE4k tag rooting your mobile phone
and applying any of the patches that are available on the Internet. Am
I right? I ask you because this solution is fine for research
purposes, but it cannot be applied if you want to publish your app or
sell it.

Regards.

 Hello Michael,

 I see that you created the NFCTagInfo App, available on the market. This
 app is, by far, the best Tag reader, because of all the little information
 it can give us, for example the HEX/ASCII values of the sectors.

 Anyway, I just wanted to point out that it is possible to simulate an NFC
 Tag with card emulation. I was able to turn on card emulation on my Samsung
 Nexus S phone which sports a PN65 (=PN544+SmartMX) chip. The emulated card
 was a MIFARE 4K, which is a Type 4 NFC Tag. Using another Nexus S and the
 NXP TagWriter app, I was able to write a plain text message on the
 card-emulated Nexus S.

 Examining the HEX data, the latter was clearly an NDEF message.
 Furthermore, the NXP Tagreader app was able to extract the plain text
 message.

 That said, full card-emulation is possible on the Nexus S!!

  Hallo,

  the current SDK does not allow you to use card emulation.

  Anyways, with card *emulation* you will not be able to simulate an
  *NFC tag* (i.e. a tag where you store simple NDEF messages). Card
  emulation mode allows to emulate a contactless smartcard (typically
  used for applications with high security requirements, like credit
  cards). While such a card (emulated or real) can be used to carry NDEF
  messages, I really doubt that this possibility will be made available
  for the Android phones.

[android-developers] Problem Creating new Contact with photo

2012-02-03 Thread Gorka PlanetMedia 
Hi,

I am trying to create a new Contact with a photo, but my code doesn´t
work properly. The thing is that the first time I execute the code the
new contact doesn´t appear on the Contacts List, but the second time I
execute it the contact appears twice and properly. I have tried the
same code but omitting the section that includes the photo and the
contact appears on the contact list fine the first time I try, so the
problem must be related to the photo inclusion.

I cannot understand why the first execution doesn´t work and the
second one does. As I said, when I create the contact for the second
time the new entrance appears twice on the contact list, with the
contact´s name, photo, and everything, so I guess the problem should
not be on the encoding.

I hope someone can help me.
Thanks a lot for yout time.

Here is my code:

..

// Get the Contact´s Picture
int id =
cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
Uri photoUri =
ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, id);

[android-developers] Share my Contact

2012-01-19 Thread Gorka 
Hi there,

I am trying to build an application to share contacts via NFC. The
thing is that I can easily share the contacts I have on my agend using
Intent.Action_PICK, but I cannot get mine, since is not in that list.
Obviously I can add my own contact, but it doesn´t make sense to me. I
guess there must be another way to get my own information, but I
cannot figure it out.

I would appreciate any suggestion.

Thanks a lot, Gorka

[android-developers] Problem working with SOAP (lib kSOAP2)

Hi,

I am trying to access to a web service using SOAP using the ksoap2
libraries. The thing is that I can make some examples work, but I
cannot access the service I am interested in.

There is the service: http://apli.bizkaia.net/APPS/DANOK/TQWS/TQ.ASMX
And that is the method I want to consult:
http://apli.bizkaia.net/APPS/DANOK/TQWS/TQ.ASMX?op=GetPasoParada

Sort description

That is my code:

private static final String SOAP_ACTION = http://tempuri.org/
LANTIK_TQWS/TQ/GetPasoParada;
private static final String METHOD_NAME = GetPasoParada;
private static final String NAMESPACE = http://tempuri.org/

TQWS/TQ.ASMX;

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); //set up
request
request.addProperty(strLinea, *); //variable name, value. I got
the variable name, from the wsdl file!
request.addProperty(strParada, 48036029); //variable name, value.
I got the variable name, from the wsdl file!
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11); //put all required data
into a soap envelope
envelope.setOutputSoapObject(request);  //prepare request
envelope.dotNet = true;
HttpTransportSE httpTransport = new HttpTransportSE(URL);

try {
httpTransport.call(SOAP_ACTION, envelope);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} //send request

SoapObject result=(SoapObject)envelope.bodyIn;
Log.d(TAG, Result:  + result.toString());

The thing is that I don´t get any response. Well, actually I do, but
it is an error message:
GetPasoParadaResponse{GetPasoParadaResult=Object reference not set to
an instance of an object.;}

It would be great if someone knows how can I solve my problem.

Thanks a lot, Gorka

 Hallo Gorka,

 for the moment Android provides no means to directly dispatch your

 Filtering should work based on the data of the URI record (both for
 the URI record itself and the SmartPoster's embedded URI record). You
 can do this with data ... /.

Hi,

Thanks for your response.

As far as I know, using techfiltering I can filter all the tags that

smart poster, ... or tnf types. If I am wrong please let me know and
tell me where can I take a look to learn how to use the techlists for
filtering.

   The problem is that, once the application is opened viaIntent, if the

[android-developers] Re: Intent not received after application started

2011-04-11 Thread Gorka 
Hi,

Here I am once again.

I have seen that if I minimize the app, when I detect a new tag the
application is restarted and the OnRestart and OnResume methods are
called. But the OnNewIntent is not received.

But the way, if the application is restarted, how can I get the
activity that was called¿?

[android-developers] Re: Intent not received after application started

2011-04-11 Thread Gorka 
Hi,

I don´t know if someone is reading me, but I don´t give up :). Maybe
that could be useful for someone in the future.
My Manifest file looks like that rigth now:

intent-filter
  action android:name=android.intent.action.MAIN /
  category android:name=android.intent.category.LAUNCHER /
/intent-filter
intent-filter
 action android:name=android.nfc.action.NDEF_DISCOVERED/
 data android:mimeType=*/* /

 category android:name=android.intent.category.DEFAULT/
/intent-filter

What is happening rigth now is that, if I start by myself the
application, it runs ok and I get the onNewIntent messages I am
supposed to used. So the application reads all the tags. However, if
the application is started when it detects a tag, it doesn´t receive
onNewIntent messages anymore.

Does anyone know how to solve this?
I continue reading ...

Bye.

 You MUST call finish() by the time you return from onResume().

 Different component types are not interchangeable.  If something is
 launching an activity, you must implement an activity to receive that.  You
 can however in that activity do something and then immediately exit so that
 the user doesn't see your activity.

[android-developers] Activity without GUI - Activity

2011-04-05 Thread Gorka 
Hi,

I want to deploy an application that reads a NFC tag and shows the
text on the screen with a Toast and reads it using a texttospeach
class. So, I don´t want to start an activity because I don´t need any
GUI. Is that possible?

I have tried to remove the activity tags from the manifest but that
way the application doesn´t work. Is it possible to set the HOME view
within the OnCreate method instead of using R.layout.main ?? If it is
possible please tell me how to do it because I don´t know how to get
this view.

Thanks a lot.

Hi again,

Sorry if I am posting too much, but I really need to make this work
today.
Here it is my manifest file. I have created a service and a receiver
to get the NDEF_DISCOVERED intent.

?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;

category 
android:name=android.intent.category.DEFAULT/
/intent-filter
/receiver

uses-feature android:name=android.hardware.nfc

Inside my project there is a receiver class which should get the
intent so that I can start the service.

public class MyIntentReceiver extends BroadcastReceiver {
static final String TAG = BROADCAST RECEIVER;

  @Override
  public void onReceive(Context _context, Intent _intent) {

Can someone tell me what I am doing wrong ??

Hi,

Thanks for your response.
I am taking a look at it.

I am not sure if I am working in the rigth way. Since I want the
service to execute when the tag is detected, I guess I have to declare
a BroadcastReceiver within my packet so that when I receive the intent
I can start the service. Is that correct? The thing is that I am not
receiving the intent at all, I am sure the action.NDEF is taking place
because I see it in the debug window. However, my receiver doesn´t get
it. The way I have declared the receiver in the manifest and in the
java class is above.

Can you please tell me if what I am doing make sense or not. Because
it seems to me that I am wasting my time because this is not the
correct form to work whit this things.

Thanks.

[android-developers] Re: Activity without GUI - Activity

2011-04-05 Thread Gorka Hernando 
Hi,

The thing is, if I create an Activity it always will show something on
the screen, rigth?
Even if I do not set any view, like in this code, it always appear the
black screen of the activity. I can call to finish as soon as I read
the tag and I show the toast, but it is not nice.

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main)
}

When you say not to load any xml what do you mean really? It would be
great not to show nothing on screen, just the toast and then call to
finish and the user would not realize that an activity has been
opened.

I am a bit new to Android, so if you can explain me more in detail it
would be great.

Thanks for your time.

  }

  Can someone tell me what I am doing wrong ??

[android-developers] SIM NFC (card emulation). SWP support?

2011-03-28 Thread Gorka Hernando 
Hi,

I have just get a SIM card where a MIFARE Classic 1k tag has been
emulated. I put it into the Samsung GT-5230N mobile phone and I can
read it with my NFC reader as a common tag. This is possible because
the 5230N has full SWP (Single Wire Protocol). Moreover, I can connect
to the applet running in the SIM and check the values as I can do with
the reader and show the values on the screen, e.g. the tickets
remaining.

As far as I see in the Internet, the Nexus S has SWP support. Is that
true? I mean, right now is the SWP available? If I insert the SIM into
the Nexus S would it work as well as it does with the S5230n? Is it
possible to access the applets and read the values to show them on the
screen??

Thanks a lot.

[android-developers] Re: NFC doubts. JSR 257 - 177

2011-01-24 Thread Gorka Hernando 
Hi,

The thing is what Andrew says. I am working with an sticker always
connected to the mobile phone, so once the mobile detects the sticker
and reads it, is not possible to read it again unless I remove it and
stick it again (what obviously is not acceptable to me). What I want
to do is somehow whenever I start my application is to be able to read
the tag without having to remove it from the mobile phone.

The sticker is similar to these ones

Thanks and regards

Has anyone been able to create a demo for NFC on Android 2.3?

The support from Google is incredibly lame:
   http://developer.android.com/resources/samples/NFCDemo/index.html

The demo does not even give you the ability to download the source
code!!!

The demo is very generic and is not a working application.

In order to be a full demo developers must have access to a sample NFC
tag or reader.  Does anyone have any recommendations for a tag/reader
they have actually used in creating a demo for NFC on Android 2.3?

 Hi,

 I´ve been working on NFC with my Samsung 5230 mobile, and now I am
 considering to move to Android. Before I do that I have some
 questions. I´ve been reading the group and the developers web page,
 but still have some doubts.

 - Is it possible to read MIFARE DESFire tags using the standard API.
 In order to do that I have always used the JSR 257 spec. but I don´t
 know if it is possible to do something similar with the current
 Android version.

 - Suppose that I have a tag that is a sticker always affixed to the
 mobile phone. Is it possible to read it always my application is
 started?? In the mobile I used to work with it was a limitation since
 once the sticker was detected the first time it could not detect it
 anymore until I removed the sticker from the mobile NFC range and got
 it close again. Would be possible using Android API to detect it
 anytime I start the app without having to remove it??

 - I am working on JavaCard too and I have developed an applet in order
 to complete the authentication steps in a secure way. Is it possible
 to access JavaCard applets in my SD card using Android API. Until that
 moment I have used the JSR 177 (APDU Connection, ...) in order to do
 that. The problem with others mobile is that to access the SD you have
 to sign your midlet with a Verysign certificate, but I don´t want to
 do this.

 Thanks a lot.
 Best regards.

[android-developers] Re: Create Image from String

2010-10-08 Thread Gorka 
Hi,

I've been doing some tests and apparently the problem is not in the
drawable, but in the way I create the InputStream.

file_handle = new RandomAccessFile(payload.file(), r);
file_handle.read(result);
String output = new String(result);

ImageView img = (ImageView)
this.findViewById(R.id.DTNApps_DTNReceive_ImageView);

byte[] bytes = output.getBytes();
InputStream in = new BufferedInputStream(new
ByteArrayInputStream(bytes));



Where am I doing something wrong?? Do I have to indicate any encoding
string (output.getBytes(US-ASCII) or something??

[android-developers] Re: How to send a photo over Bluetooth

2010-07-01 Thread Gorka 
Hi,

Thank you, it seems that is exactly what I wanted. I have not tested
it but apparently it works. By the way, I saw there is not an specific
function defined by the FileInputStream class to know the number of
bytes of the picture; do you know how can I get this value. I mean, I
am using this code:

FileInputStream f;
byte[] message_byte_array = new byte[512];

Log.d(TAG, Sending photo);

try {
  f = new FileInputStream(/sdcard/DCIM/Camera/prueba.jpg);
  int i = f.read(message_byte_array);

 

  f.close();
}


Read returns the number of bytes read, but there is any way to know
this number before to create the byte[] array accordingly??


Once again thanks for your time, Gorka.

 I hope this helps.

[android-developers] RfComm channel using listenUsingRfcommWithServiceRecord

2010-05-07 Thread Gorka 
Hi,

I am using listenUsingRfcommWithServiceRecord method to register my
service in the mobile. Apparently the rfcomm channel where the service
is registered is random, or at least it is not always the same.

Can I somehow force the channel to be associated always to a
particular RfComm channel?? That would be great in order to ease the
communication between the android and my Bluetooth device.

Thank you and regards
