The full documentation of the default NFC protocol can be found hereĮxample: byte response = new byte These bytes are the default read and write bytes for the transmit function. Private static final byte WRITE = (byte) 0xA2 private static final byte READ = (byte) 0x30 If you want to write to your NFC reader use the transmit function to send byte arrays. However it doesn't seem to have an option to write data. Here can you find the documentation for the libraries and example code. those will work right out of the box, that's what we are doing. I think your best option is to get a couple of NFC Phones such as the Galaxy Nexus S, DROID Razr, Xperia S, HTC Incredible, etc. if you are thinking about going to and import a tablet with NFC reader, think twice, because that ones might not allow you to do all what the NXP Semiconductors chip does with Android Beam (TM) such as Read/Write and support different I/O operations with NFC-A, B, F, V or ISO-DEP.įor your time's sake (and because time is the most valuable asset for anyone these days). and there are no warranties that you'll succeed.Īnd. When a manufacturer launch a new phone with a different NFC chip is because someone have created the drivers to use such chips and interface with Android's NFC classes, specifically the NfcManager class and the NfcAdapter class wich represents the local NFC adapter.īest case scenario, you could use the Android NDK to create low level C/C++ classes to communicate somehow the External NFC Card reader with Android and then make more custom programming with the NDK to make the NfcAdapter on the SDK to detect it. Neither Froyo 2.3 (min SDK version supporting NFC) or Ice Cream Sandwich 4.0 are compatible with a wide variety of chips.
