Developing NFC Applications with Android

Near Field Communication (NFC) applications can be developed in the three NFC operating modes in the reader/writer mode, the P2P mode, and in the card emulation mode. This chapter introduces mobile applications programming on the Android platform in the three NFC modes, including the HCE mode. Several Integrated Development Environments (IDEs) enable Android application development. The Google Play Developer Console enables Android apps developers/providers to publish theirs apps. The very first prerequisite to access NFC feature is to enable the NFC option from Android's connectivity parameters. An Android HCE service extends HostApduService superclass; the Applet class of JavaCard implementing an HCE service requires overriding the processCommandApdu method receiving the APDU command as parameter. In order for intents to be routed toward the BroadcastReceiver, the latter must previously register in the system. Android offers two solutions to declare a BroadcastReceiver: a static declaration in a manifest file or a dynamic declaration when processed.
