Question

起初，我能够通过运行ICS（4.0.4）的Android手机轻松连接/断开和接收我的蓝牙远程设备。
最近，某种程度上，我的应用程序不再起作用了没有错误，只是没有发送或接收数据，因为没有连接创建套接字我的第一个猜测是我的硬件，但事实并非如此我尝试了我的基本蓝牙连接应用程序，它们也不会工作。
这是logcat：

我看到有几个人在ICS上遇到与蓝牙连接相同的问题我也尝试使用this修复它，但它也不起作用。
它说：Could not create Insecure RFComm Connection.

以下是摘录：

private BluetoothAdapter btAdapter = null;
      private BluetoothSocket btSocket = null;
      private StringBuilder sb = new StringBuilder();

      private ConnectedThread mConnectedThread;

      // SPP UUID service
      private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

      // MAC-address of Bluetooth module (you must edit this line)
      private static String address = "20:13:06:24:05:60";

的OnCreate

btAdapter = BluetoothAdapter.getDefaultAdapter();

private BluetoothSocket createBluetoothSocket(BluetoothDevice device) throws IOException {
          if(Build.VERSION.SDK_INT >= 10){
              try {
                  final Method  m = device.getClass().getMethod("createInsecureRfcommSocketToServiceRecord", new Class[] { UUID.class });
                  return (BluetoothSocket) m.invoke(device, MY_UUID);
              } catch (Exception e) {
                  Log.e(TAG, "Could not create Insecure RFComm Connection",e);
              }
          }
          return  device.createRfcommSocketToServiceRecord(MY_UUID);
      }

      public void bluetoothDisconnect(){
          try     {
              btSocket.close();
            } catch (IOException e2) {
              errorExit("Fatal Error", "In onPause() and failed to close socket." + e2.getMessage() + ".");
            }

      }

      public void bluetoothConnect(){
        // Set up a pointer to the remote node using it's address.
            BluetoothDevice device = btAdapter.getRemoteDevice(address);

            // Two things are needed to make a connection:
            //   A MAC address, which we got above.
            //   A Service ID or UUID.  In this case we are using the
            //     UUID for SPP.

            try {
                btSocket = createBluetoothSocket(device);
            } catch (IOException e) {
                errorExit("Fatal Error", "In onResume() and socket create failed: " + e.getMessage() + ".");
            }

            /*try {
              btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
            } catch (IOException e) {
              errorExit("Fatal Error", "In onResume() and socket create failed: " + e.getMessage() + ".");
            }*/

            // Discovery is resource intensive.  Make sure it isn't going on
            // when you attempt to connect and pass your message.
            btAdapter.cancelDiscovery();

            // Establish the connection.  This will block until it connects.
            Log.d(TAG, "...Connecting...");
            try {
              btSocket.connect();
              Log.d(TAG, "....Connection ok...");
            } catch (IOException e) {
              try {
                btSocket.close();
              } catch (IOException e2) {
                errorExit("Fatal Error", "In onResume() and unable to close socket during connection failure" + e2.getMessage() + ".");
              }
            }

            // Create a data stream so we can talk to server.
            Log.d(TAG, "...Create Socket...");

            mConnectedThread = new ConnectedThread(btSocket);
            mConnectedThread.start();


      }

这个问题是否可以解决？特别是对于这个Android版本？
