MifareSam

Provides access to MIFARE SAM properties and I/O operations on an SAM object. This class encapsulates all the methods required for authenticating the host with MiFare SAM.

Example Usage:

public class MainActivity extends Activity implements EMDKListener {

SecureNfcManager secureNfcManager;
EMDKManager emdkManager;
SamType samType;
MifareSam mifareSam;


protected void onCreate(Bundle savedInstanceState) {

EMDKResults results = EMDKManager.getEMDKManager(
getApplicationContext(), this);
}


public void onOpened(EMDKManager emdkManager) {

this.emdkManager = emdkManager;

this.secureNfcManager = (secureNfcManager) this.emdkManager
.getInstance(FEATURE_TYPE.SECURENFC);

if (this.secureNfcManager != null) {

samType = secureNfcManager.getAvailableSam();

if (samType.equals(SamType.MIFARE)) {
mifareSam = (MifareSam) secureNfcMgr
.getSamInstance(samType);
if (mifareSam != null) {
try {
SamMode samMode = mifareSam.connect();

mifareSam.authenticateSam(authKey, samKey, null);

mifareSam.close();
} catch (MifareSamException e) {
e.printStackTrace();
}
}
}
}
}


public void onDestroy() {
if (this.emdkManager != null)
this.emdkManager.release();
}


public void onClosed() {
this.emdkManager.release();
}

}

Throws:

com.symbol.emdk.securenfc.MifareSamException

The exception will be thrown if it fails to establish connection with the SAM.
