Box 2.8. Android: initializing the NFC adapter

NfcAdapter nfcAdapter = NfcAdapter.getDefaultAdapter(this);

if (!nfcAdapter.isEnabled())

{

//Ask the user to activate the NFC option

}

NOTE.– It is to be noted that if no NFC controller is installed (in the case of a peripheral device that is not NFC enabled), the NFC adapter instance will be null. You will also need to test that the NFC option was properly activated by the user in the system configuration of the Android device (see Figure 2.22) with the isEnabled() method of the adapter, as shown in the source code of Box 2.8.
