Java Android BluetoothSocket:：connect（）引发异常

我无法启动Java服务器（使用Windows 7 x64上的

bluecove 2.1.1，外部蓝牙加密狗

）和

Android

客户端（操作系统版本2.3.6）之间的蓝牙连接

设备发现工作正常，但我无法连接到PC上运行的服务（

BluetoothSocket:：connect（）引发异常

）。下面是一个非常原始的服务器和客户端版本（我使用

蓝牙加密狗的
MAC地址
，以减少代码长度）：

Java服务器

import java.io.*;
import javax.microedition.io.*;
import javax.bluetooth.*;

public class RFCOMMServer {

public static void main(String args[]) {
    try {

        StreamConnectionNotifier service = (StreamConnectionNotifier) Connector
                .open("btspp://localhost:"
                        + new UUID("0000110100001000800000805F9B34FB",
                                false).toString() + ";name=helloService");

        StreamConnection conn = (StreamConnection) service.acceptAndOpen();
        System.out.println("Connected");

        DataInputStream in = new DataInputStream(conn.openInputStream());
        DataOutputStream out = new DataOutputStream(conn.openOutputStream());

        String received = in.readUTF();         // Read from client
        System.out.println("received: " + received);

        out.writeUTF("Echo: " + received);      // Send Echo to client

        conn.close();
        service.close();
    } catch (IOException e) {
        System.err.print(e.toString());
    }
}
}

安卓客户端

public class AndroidBluetoothEchoClientActivity extends ListActivity {
LinearLayout layout;

private ArrayAdapter<String> mArrayAdapter;

final Handler handler = new Handler();

final Runnable updateUI = new Runnable() {
    public void run() {
        mArrayAdapter.add(bluetoothClient.getBluetoothClientData());
    }
};

BluetoothClient bluetoothClient;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mArrayAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1);
    this.setListAdapter(mArrayAdapter);
    bluetoothClient = new BluetoothClient(handler, updateUI);
    bluetoothClient.start();
}
}

class BluetoothClient extends Thread {

BluetoothAdapter mBluetoothAdapter;
private String data = null;

final Handler handler;
final Runnable updateUI;

public BluetoothClient(Handler handler, Runnable updateUI) {
    this.handler = handler;
    this.updateUI = updateUI;

    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
}

public String getBluetoothClientData() {
    return data;
}

public void run() {
    BluetoothSocket clientSocket = null;
                                        // Client knows the MAC address of server
    BluetoothDevice mmDevice = mBluetoothAdapter
            .getRemoteDevice("00:15:83:07:CE:27");

    try {

        clientSocket = mmDevice.createRfcommSocketToServiceRecord(UUID
                .fromString("00001101-0000-1000-8000-00805F9B34FB"));

        mBluetoothAdapter.cancelDiscovery();

        clientSocket.connect();
        DataInputStream in = new DataInputStream(clientSocket.getInputStream());
        DataOutputStream out = new DataOutputStream(clientSocket.getOutputStream());

        out.writeUTF("Hello");          // Send to server

        data = in.readUTF();            // Read from server
        handler.post(updateUI);
    } catch (Exception e) {
    }
}
}

我尝试使用反射：

Method m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
clientSocket  = (BluetoothSocket) m.invoke(device, 1);

但它也不起作用

一个多星期以来，我无法解决这个问题，如果您能帮助我做出决定，我将不胜感激

问题解决了，只是我的设备和PC上的验证码不同，但Windows在配对设备列表中显示了设备。我修理了这个装置，它就工作了
