[android-developers] How to display log?
Hi, I have a Google Nexus S. Using this guide: http://forum.androidcentral.com/t-mobile-nexus-s-rooting-roms-hacks/48675-how-compile-nexus-s-kernel-source.html When I compile kernel I added some LOGD to cpp files. But when I do adb logcat I don't see it in console. I'm triying to enable smart card feature of Google Nexus S modifying this sources: http://groups.google.com/group/android-developers/browse_thread/thread/d5fc35a9f16aa467/dec4843abd73d9e9?lnk=gstq=secure+element+diff%27s#dec4843abd73d9e9 I think that when I re-compile kernel, the process doesnt clean old code and shows me the old code. Any ideas? Thanks! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Thanks! I posted it a few minutes ago in porting and platform!

Post to a more relevant group - like porting or platform - if you're compiling the kernel. --- -- TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

Have anyone read this? 2.3.4. adds hidden classes for secure element and related: http://gibraltarsf.com/blog/?p=247 On Jun 2, 2:55 pm, Jorn Cruijsen jorncruij...@gmail.com wrote: Hey Michael, Oh, it seems I failed terribly..

Yes, I'm very sure it is emulating a MIFARE Classic 4K card and an APDU based smart card (depending on the protocol activation level). When I put the device in emulation mode and read its ATR, I'm getting: 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 00 00 00 00 00 6B Decoding this PC/SC ATR gives this: 3B ... Contactless card 8F ... Number of historical bytes: 0xF (15) 80 01 80 ... Category indicator: A status indicator may be present in an optional COMPACT-TLV data object. 4F ... Application identifier Presence indicator 0C ... Length of application identifier: 0x0C (12) Application identifier: A0 00 00 03 06 ... RID: PC/SC Working Group 03 ... Byte for Standard: ISO 14443 A, part 3 00 00 ... Bytes for Card Name: not in standard 00 00 00 00 ... RFU (Shall be set to zero) 6B ... Checksum This is a typical ATR if the card emulation mode is not activated. I receive that ATR if I put the phone in peer-to-peer communication mode (which is the default if card emulation is disabled). While I'm actually expecting: 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 02 00 00 00 00 69 With the phone you would not normally receive such an ATR for the card emulation mode either. Usually a contactless smart card reader (like the Omnikey 5321) activates the contactless smart card up to its highest supported protocol layer. For the SmartMX, this means that ISO 14443-4 protocol layer is activated for APDU based communication with the JavaCard. Thus, the ATR generated by the smart card reader would reflect the properties of the APDU-based JavaCard and not those of the MIFARE 4K area. This is the value I recieve when card emulation is on: 3B 8A 80 01 00 31 C1 73 C8 40 00 00 90 00 90 Best regards, Michael -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Making SmartCard feature available in Google Nexus S
Hi, I'm back to ask a little questions about nfc. I have a NFC tag reader and Google Nexus S. I want to create an app for Google Nexus S that emulates a nfc tag. 1) Where I could find example code in java? Because there isn't no info about this. I think it could be similar to: -Creating the nfc tag to emulate (give him a value) -Activating emulation of nfc tag -Wait for a NFC tag reader signal (NFC tag reader sends a message telling to the phone, msg received?) -Desactivating emulation of nfc tag My NFC reader is CPR40.30-USB (More info: http://www.toptunniste.fi/topshop/product_details.php?p=264c=76). 2) Should I create new functions to use it and create a new SDK? Did you know any tutorial to modify SDK and create other functions? Or should I create it in NDK using native code? 3) The steps to enable Google Nexus S Smart Card functionality will be: -Unlock the boot loader -Root Google Nexus S -Create the modified rom (with the diff you posted in http://groups.google.com/group/android-developers/browse_thread/thread/d5fc35a9f16aa467/dec4843abd73d9e9%3Flnk%3Dgst%26q%3Dsecure%2Belement%2Bdiff%2527s%23dec4843abd73d9e9 ). -Load the new rom. -Install the app 4) Do you know when all nfc funcionality will be available in the official SDK? Thanks!

I was able to get the SmartMX secure element to be exposed in both wired mode and visible to other NFC readers. Other than that though, I'm not sure much else can be done to the SE such as loading applications to it because it is locked down and you need the secret keys to write to those parts of its memory. I'm pretty sure only Google and NXP know what those keys are. I did not make my changes to the Cyanogen source though; but rather the plain Android source base. After unlocking the bootloader on the Nexus S and loading my version of the OS, NFC emulation mode was working.
