android访问NFC的SE所有文档都在这里。
可惜的是，目前只能访问内部SE，对于外部sim或SD的SE，几乎所有的手机都不支持，原因：支持SIM卡的SE，还没有AT命令；支持SD卡的SE，还没有API接口。为什么会这样，很简单，因为它们不是google，没有开源的精神！所以我们现在只能访问内部SE，就是存在NFC芯片的SE。
访问SE使用的是SEService/Smartcard Service。手机上必须要安装SEService/Smartcard Service，这个由手机研发实现。
创建
[html]
seService = new SEService(this, this);
继承
[html]
implements SEService.CallBack
实现接口
[html]
public void serviceConnected(SEService service)
{
}
就可以访问SE了，代码如下：
[html]
public class MainActivity extends Activity implements SEService.CallBack {
private SEService seService;
NfcAdapter mNfc;
TextView mTextView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mNfc = NfcAdapter.getDefaultAdapter(this);
// do layout and UI stuff
setContentView(R.layout.main);
mTextView = (TextView) this.findViewById(R.id.text);
try {
// 访问SEService
seService = new SEService(this, this);
} catch (SecurityException e) {
mTextView.append("Binding not allowed, uses-permission SMARTCARD?");
} catch (Exception e) {
mTextView.append("Exception: " + e.getMessage());
}
}
@Override
protected void onDestroy() {
if (seService != null && seService.isConnected()) {
seService.shutdown();
}
super.onDestroy();
}
//连接上SEService
public void serviceConnected(SEService service)
{
Session session = null;
Channel basicChannel = null;
try {
mTextView.append("Getting available readers...\n");
Reader[] readers = seService.getReaders();
//readers[1]就是内部SE
session = readers[1].openSession();
//选择card manager aid
byte[] aid = {(byte) 0xA0,0x00,0x00,0x00,0x03,0x00,0x00,0x00};
basicChannel = session.openBasicChannel(aid);
//readers[1]获取card prodution life cycle 数据
byte[] CPLC = {(byte) 0x80,(byte) 0xca,(byte) 0x9f,0x7f,0x00};
byte[] response1 = basicChannel.transmit(CPLC);
if(response1.length>=20)
{
mTextView.append(String.format("SerialID: %02x%02x%02x%02x\n",
response1[15],response1[16],response1[17],response1[18]));
}
} catch (Exception e) {
mTextView.append("Error occured: "+e.getMessage()+"\n");
}
if(basicChannel!=null)
basicChannel.close();
if(session!=null)
session.close();
}
}
