hello! If i right, you said me that i need to root my phone, didn't you? If i don't, i can't access to libnfc-nxp resources, didn't I?

Hello, I do not know exactly about rooting for libnfc-nxp. I have no experience with the phones. You should to try or to ask someone else.

[android-developers] Re: NFC at Digital Protocol Layer
Hello, I'm going to read the information that you had me but after that i have some questions: if I'm not mistaken, the android phones that supports NFC have PN65N or PN544 chip and libnfc doesn't support those chips. am i mistaken? if libnfc doesn't support those chips why i am interested in doing a port to android? thanks for your replay On 16 dic, 12:21, Alex Che alexey.tchervin...@gmail.com wrote: Hi, I am not guarantee my information ultimately exact. 1. AFAIK, Google use libnfc-nxp library which has functions for P2P data exchange, may be it is actually DEP. 2. There is open-source libnfc library intended for Linux.

In my mind, both approaches assume programming on NDK level (in C).
