我一直在玩弄为Android 2.2（API级别8上，HTC Desire）蓝牙API，并一个应用程序连接到嵌入式蓝牙设备的使用：

  device.createRfcommSocketToServiceRecord（DEV_UUID）;
 

这产生预期，但是精简我想避免用户交互连接过程中，当配对感动到API级别10（HTC Desire采用的CyanogenMod 7）的配对请求，所以我可以使用：

  device.createInsecureRfcommSocketToServiceRecord（DEV_UUID）;
 

在这个测试也按预期工作（连接不提示用户配对），但是当我尝试使用2.2作为前下创建API级别10安全RfcommSocket我得到一个连接被拒绝的例外......

  java.io.IOException异常：连接被拒绝
    在android.bluetooth.BluetoothSocket.connectNative（本机方法）
    在android.bluetooth.BluetoothSocket.connect（BluetoothSocket.java:204）
 

据我可以告诉这应该仍然工作以同样的方式，提示用户对？

编辑：

只需再次尝试使用下面的code和结果是相同的（工作不安全而不是安全的），我会尽量让我的手股票2.3设备上进行测试的。

 尝试{
            方法M = dev.getClass（）实现getMethod（createInsecureRfcommSocketToServiceRecord，新的等级[] {} UUID.class）。
            的BluetoothSocket BS =（的BluetoothSocket）m.invoke（DEV，devUUID）;
            Log.d（TEST，方法调用）;
            bs.connect（）;
            Log.d（TEST，连接到插座）;
            bs.close（）;
            Log.d（TEST，关闭套接字）;
        }
 

解决方案

尽管找我的应用程序类似的问题的解决方案，我发现这个博客从code.google.com

这将帮助所有那些谁仍然在寻找对SO

http://mobisocial.stanford.edu /新闻/ 2011/03 /蓝牙反射和遗留-NFC / （链接不工作了）

该解决方案变得非常简单了。只包含InsecureBluetooth.java在您的项目，并更改BluetoothChatService.java 2行。

  TMP = InsecureBluetooth.listenUsingRfcommWithServiceRecord（mAdapter，姓名，MY_UUID，真正的）;
 

和

  TMP = InsecureBluetooth.createRfcommSocketToServiceRecord（设备，MY_UUID，真正的）;
 

完蛋了！

I have been playing around with the bluetooth API for Android 2.2 (API level 8, HTC Desire) and had an app connecting to an embedded Bluetooth device using:

device.createRfcommSocketToServiceRecord(DEV_UUID);

This generated a pairing request as expected, however to streamline the connection process I wanted to avoid the user interaction when pairing so moved to API level 10 (HTC Desire with CyanogenMod 7) so I could use:

 device.createInsecureRfcommSocketToServiceRecord(DEV_UUID);

When testing this also works as expected (connecting without prompting the user to pair), however when I try to create the secure RfcommSocket under API level 10 as before with 2.2 I get a connection refused exception...

 java.io.IOException: Connection refused
    at android.bluetooth.BluetoothSocket.connectNative(Native Method)
    at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:204)

As far as I can tell this should still work in the same way, prompting the user to pair?

EDIT:

Just tried again using the following code and the outcome is the same (working for insecure but not for secure), I will try and get my hands on a stock 2.3 device to test on.

        try {
            Method m = dev.getClass().getMethod("createInsecureRfcommSocketToServiceRecord", new Class[] { UUID.class } );
            BluetoothSocket bs = (BluetoothSocket)m.invoke(dev, devUUID);
            Log.d("TEST", "Method Invoked");
            bs.connect();
            Log.d("TEST", "Connected to socket");
            bs.close();
            Log.d("TEST", "Closed Socket");
        }

While looking for the solution of similar problem in my app, I have found this blog from code.google.com

It will help all those who are still looking for this problem solution on SO

http://mobisocial.stanford.edu/news/2011/03/bluetooth-reflection-and-legacy-nfc/ (link not working anymore)

The solution has become very simple now. Just include InsecureBluetooth.java in your project and change 2 lines in BluetoothChatService.java.

tmp = InsecureBluetooth.listenUsingRfcommWithServiceRecord(mAdapter, NAME, MY_UUID, true);

and

tmp   = InsecureBluetooth.createRfcommSocketToServiceRecord(device, MY_UUID, true);

Thats it !
