Provides classes that manage the NFC functionality.

+ +

The NFC functionality is related to Near Field Communication.

+ +

The NFC APIs let applications:

+
    +
  • Scan for remote NFC targets (NFC Tag or NFC Peer)
    • +
  • Transfer raw data to and from remote NFC targets (NFC Tags or NFC Peer)
    • +
  • Read/Write NDEF data from/to remote NFC targets (NFC Tags)
    • +
  • Establish LLCP connection with a remote NFC target (NFC Peer with LLCP support)
    • +
  • Exchange data with a remote NFC target through LLCP services (NFC Peer with LLCP support)
    • +
  • Be notified of transactions on the local Secure Element by an external NFC reader
    • +
+ + +

Setting Up NFC

+ +

+Before an application can use the NFC feature, it needs to check if NFC is +supported on the device by getting an instance of the +{@link com.trustedlogic.trustednfc.android.NfcManager} class. +

+ +
+	NfcManager mNfcManager = (NfcManager) getSystemService(Context.NFC_SERVICE);
+	if (mNfcManager == null) {
+		// Device does not support NFC
+	}
+
+ +

+An application can ensure that NFC is enabled. +If not, an application with the needed permission can request that NFC be +enabled. +

+ +
+	if (!mNfcManager.isEnabled) {
+		// NFC is currently disabled.
+		// Enable NFC.
+		mNfcManager.enable();
+	}
+
+ +

+Before using the card emulation mode, an application can ensure that a secure +element is selected ({@link com.trustedlogic.trustednfc.android.NfcManager#getSelectedSecureElement}). +If not, an application with the needed permission can recover the list of +available secure elements on the device +({@link com.trustedlogic.trustednfc.android.NfcManager#getSecureElementList}) and select one +({@link com.trustedlogic.trustednfc.android.NfcManager#selectSecureElement}). +

+ +

+Before using the NFC feature, an application can configure the NFC device by +calling {@link com.trustedlogic.trustednfc.android.NfcManager#setProperties}. This function allows: +

+
    +
  • Enabling/disabling the NFC device capabilities (RF types, baudrates, + NFCIP-1 mode and role...)
    • +
  • Settings the NFCIP-1 general bytes and the LLCP link parameters
    • +
+

+The setting properties can be customized according to the Device capabilities. +The next table give the minimal set of properties supported by the Device. +Depending on the implementation, the table may be completed. +

+ + + + + + + + + + + + + + + +

+ + +

NFC Permissions

+ +

+To change the NFC service settings such as enabling the NFC targets +discovery or activating the secure element, an application must declare the +NFC_ADMIN permission. +

+

+To perform NFC raw communication with a remote NFC target in +Reader/Write Mode or Peer-to-Peer Mode, an application must declare the NFC_RAW +permission. +

+

+To receive NDEF message or Secure Element intents, an application must declare +the NFC_NOTIFY permission. +

+

+To receive the LLCP link intent and perform an LLCP communication with a remote NFC target, an application must +declare the NFC_LLCP permission. +

+ + +

NFC Usage

+ +

+The following code samples illustrate the APIs usage regarding the NFC service +use cases. +

+ +

Reader/Writer Mode NDEF message notification

+ +

+This code sample illustrates the NDEF message notification through an Intent declared in the manifest and a receiver implemented in the application. +

+

Main involved classes/methods:

+ +

Manifest Example:

+
+	<receiver android:name=".NfcReaderDemoReceiver">
+            <intent-filter>
+               <action android:name= "com.trustedlogic.trustednfc.android.action.NDEF_TAG_DISCOVERED"/>
+            </intent-filter>
+        </receiver>
+
+ +

Receiver Example:

+
    +
  • {@link com.trustedlogic.trustednfc.android.NdefMessage}
    • +
  • {@link com.trustedlogic.trustednfc.android.NfcManager#NDEF_TAG_DISCOVERED_ACTION}
    • +
  • {@link com.trustedlogic.trustednfc.android.NfcManager#NDEF_MESSAGE_EXTRA}
    • +
+

Card Emulation Mode transaction notification

+ +

+This code sample illustrates how to get the card emulation notification with the declaration of a Receiver in the manifest of the application and the implementation +of the receiver in the application. +

+

Manifest Example:

+
+	<receiver android:name=".NfcReaderDemoReceiver">

+		<action android:name= "com.trustedlogic.trustednfc.android.action.TRANSACTION_DETECTED"/>
+            </intent-filter>
+        </receiver>
+
+ +

Receiver Example:

+
    +
  • {@link com.trustedlogic.trustednfc.android.NfcManager#TRANSACTION_DETECTED_ACTION}
    • +
  • {@link com.trustedlogic.trustednfc.android.NfcManager#AID_EXTRA}

+			/* Manage the AID: */
+			/* For example start an activity related to this AID value or display a popup with the AID */
+		} 
+	}
+
+ + + +

Multiple Applications rules

+ +

+Several LLCP sockets can be created by a single application or by multiple +applications by calling {@link com.trustedlogic.trustednfc.android.NfcManager#createLlcpSocket}, +{@link com.trustedlogic.trustednfc.android.NfcManager#createLlcpConnectionlessSocket} or +{@link com.trustedlogic.trustednfc.android.NfcManager#createLlcpServiceSocket}, provided the local SAP +numbers are differents. +

+ +

+Only one application can open a raw connection by calling +{@link com.trustedlogic.trustednfc.android.NfcManager#openTagConnection} or +{@link com.trustedlogic.trustednfc.android.NfcManager#openP2pConnection}. +While this application has not closed or cancelled its connection, any other +application that attempts to open another raw connection will raise an +exception. +During an open connnection, the card emulation mode is always enabled and +applications are able to receive card emulation intents. +

+ +

+When an application opens a tag connection by calling +{@link com.trustedlogic.trustednfc.android.NfcManager#openTagConnection}, this operation is exclusive, no NDEF message intent are +broadcast while the connection is not closed or canceled. +

+ +

+When an application opens a peer-to-peer connection by calling +{@link com.trustedlogic.trustednfc.android.NfcManager#openP2pConnection}, this operation is exclusive, no LLCP intent are broadcast and LLCP sockets are +disabled while the connection is not closed or canceled. +

+ + +

NFC Tag types

+ +

+The {@link com.trustedlogic.trustednfc.android.NfcTag} type returned by +{@link com.trustedlogic.trustednfc.android.NfcTag#getType} indicates the set of +commands supported by the tag. These commands can be used in +{@link com.trustedlogic.trustednfc.android.NfcTag#transceive}. +
