		/**
		* <p>HostNfcFService is a convenience {@link Service} class that can be
		* extended to emulate an NFC-F card inside an Android service component.
		*
		* <h3>NFC Protocols</h3>
		* <p>Cards emulated by this class are based on the NFC-Forum NFC-F
		* protocol (based on the JIS-X 6319-4 specification.)</p>
		*
		* <h3>System Code and NFCID2 registration</h3>
		* <p>A {@link HostNfcFService HostNfcFService service} can register
		* exactly one System Code and one NFCID2. For details about the use of
		* System Code and NFCID2, see the NFC Forum Digital specification.</p>
		* <p>To statically register a System Code and NFCID2 with the service, a {@link #SERVICE_META_DATA}
		* entry must be included in the declaration of the service. An example of a HostNfcFService
		* manifest declaration is shown below:
		*
		* <pre> <service android:name=".MyHostNfcFService" android:exported="true" android:permission="android.permission.BIND_NFC_SERVICE">
		* <intent-filter>
		* <action android:name="android.nfc.cardemulation.action.HOST_NFCF_SERVICE"/>
		* </intent-filter>
		* <meta-data android:name="android.nfc.cardemulation.host_nfcf_service" android:resource="@xml/nfcfservice"/>
		* </service></pre>
		*
		* This meta-data tag points to an nfcfservice.xml file.
		* An example of this file with a System Code and NFCID2 declaration is shown below:
		* <pre>
		* <host-nfcf-service xmlns:android="http://schemas.android.com/apk/res/android"
		* android:description="@string/servicedesc">
		* <system-code-filter android:name="4000"/>
		* <nfcid2-filter android:name="02FE000000000000"/>
		* </host-nfcf-service>
		* </pre>
		*
		* <p>The {@link android.R.styleable#HostNfcFService <host-nfcf-service>} is required
		* to contain a
		* {@link android.R.styleable#HostApduService_description <android:description>}
		* attribute that contains a user-friendly description of the service that may be shown in UI.
		* <p>The {@link android.R.styleable#HostNfcFService <host-nfcf-service>} must
		* contain:
		* <ul>
		* <li>Exactly one {@link android.R.styleable#SystemCodeFilter <system-code-filter>} tag.</li>
		* <li>Exactly one {@link android.R.styleable#Nfcid2Filter <nfcid2-filter>} tag.</li>
		* </ul>
		* </p>
		*
		* <p>Alternatively, the System Code and NFCID2 can be dynamically registererd for a service
		* by using the {@link NfcFCardEmulation#registerSystemCodeForService(ComponentName, String)} and
		* {@link NfcFCardEmulation#setNfcid2ForService(ComponentName, String)} methods.
		* </p>
		*
		* <h3>Service selection</h3>
		* <p>When a remote NFC devices wants to communicate with your service, it
		* sends a SENSF_REQ command to the NFC controller, requesting a System Code.
		* If a {@link NfcFCardEmulation NfcFCardEmulation service} has registered
		* this system code and has been enabled by the foreground application, the
		* NFC controller will respond with the NFCID2 that is registered for this service.
		* The reader can then continue data exchange with this service by using the NFCID2.</p>
		*
		* <h3>Data exchange</h3>
		* <p>After service selection, all frames addressed to the NFCID2 of this service will
		* be sent through {@link #processNfcFPacket(byte[], Bundle)}, until the NFC link is
		* broken.<p>
		*
		* <p>When the NFC link is broken, {@link #onDeactivated(int)} will be called.</p>
