I am developing one android application for transfering a file over NFC. I have 2 tabs in my application
I do not know how to get request and response from NFC. Suppose I send any file from my files tab ListView to another device then it means I send request to that device and the file which I send should be saved in application's request folder of other user. If they click on that file from request then add that file in the device SD card.
below link might help you where he has explained how to transfer files b/w 2 android devices...
