Now I want to do the same thing with NFC but the all samples I've found so far are starting an activity when NFC tag is discovered. This document describes advanced NFC topics, such as working with various tag technologies, writing to NFC tags, and foreground dispatching, which allows an application in the foreground to handle intents even when other applications filter for the same ones. Most (older) examples are using the Intent based approach: you are setting filters and use the tag dispatch system to be informed when an NFC tag is tapped to the NFC reader in your Android.
