Question

这是我的代码：

Thread connectThread = new Thread(new Runnable() {

            @Override
            public void run() {
                try {
                    boolean gotuuid = btDevices.getItem(position)
                            .fetchUuidsWithSdp();
                    if (gotuuid){
                        UUID uuid = btDevices.getItem(position).getUuids()[0]
                                .getUuid();
                        mbtSocket = btDevices.getItem(position)
                                .createRfcommSocketToServiceRecord(uuid);

                        mbtSocket.connect();
                    } else {
                        Log.e("ID22", "There is no uuid");
                    }


                } catch (IOException ex) {
                    runOnUiThread(socketErrorRunnable);
                    try {
                        mbtSocket.close();
                    } catch (IOException e) {
// e.printStackTrace();
                    }
                    mbtSocket = null;
                    return;
                } finally {
                    runOnUiThread(new Runnable() {

                        @Override
                        public void run() {
                            finish();

                        }
                    });
                }
            }
        });

        connectThread.start();
    }

当我尝试使用mbtSocket.connect();连接到蓝牙soccket时，它会停止并抛出socketErrorRunnable异常。你知道如何解决这个问题吗？我搜索了一下，但没有什么对我有用。

如果您遇到麻烦，请参阅官方Android Bluetooth Chat示例中的一些代码：

服务器端：

public class BluetoothServer {
    private final static String TAG = "BluetoothServer";
    private final BluetoothServerSocket serverSocket;

    // I would recommand defining a secure connexion so forget the unsecore UUID
    private static final UUID MY_UUID_SECURE =
            UUID.fromString("fa87c0d0-afac-11de-8a39-0800200c9a66"); // choose another UUID go to a site that generates a random UUI ;-)
    private static final UUID MY_UUID_INSECURE =
            UUID.fromString("8ce255c0-200a-11e0-ac64-0800200c9a66"); // choose another UUID go to a site that generates a random UUI ;-)
    // BUT THIS WILL BE THE UUID YOU NEED TO CONNECT TO IN YOUR CLIENT APP -> createRfcommSocketToServiceRecord(UUID.fromString("0800200c9a66"));
    // Name for the SDP record when creating server socket
    private static final String NAME_SECURE = "BluetoothChatSecure";
    private static final String NAME_INSECURE = "BluetoothChatInsecure";

    public BluetoothServer(BluetoothAdapter adapter, boolean secure) {
        try {
            if (secure) {
                this.serverSocket = adapter.listenUsingRfcommWithServiceRecord(NAME_SECURE,
                        MY_UUID_SECURE);
            } else {
                this.serverSocket = adapter.listenUsingInsecureRfcommWithServiceRecord(
                        NAME_INSECURE, MY_UUID_INSECURE);
            }
        } catch (IOException e) {
            Log.e(TAG, "Socket Type: " + (secure ? "secure" : "insecure") + "listen() failed", e);
        }
    }

    public void asyncStartServer() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    final BluetoothSocket socket = serverSocket.accept(); // blocks/wait until your phone connects
                    // at this point, your phone is connected
                    final InputStream is = socket.getInputStream();
                    // and now start reading
                } catch (IOException ioe) {
                    Log.getStackTraceString(ioe);
                }
            }
        }).start();
    }
}
