mtk, very cool! So when you did that call directly (somewhere in init of the jni code?) you got it to detect? How are you sending APDU commands? Also, if I understand wired mode correctly, the tag is not emulated externally to other readers; it's only available internally using the NFC API?
gusdgg, yes, I saw the secure elements using the getSecureElementList() and just doing logging with those and observing them using `adb logcat`. I think that is in one of the diffs I posted. It worked OK for me and I wasn't seeing any permission errors. Though I never even bothered to do it via reflection on the stock firmware since I figured it would just deny it. Your findings clearly confirm that. As for the SmartMX chip, maybe you're right. But I suppose it could also be built into the PN544 chip itself. I have no idea, I wasn't able to find any datasheets that talk about it and have no details on the NXP chips Samsung's been sourcing for the Nexus S.
