Android蓝牙代码在2.2上运行良好，但在2.3或2.3.3上运行不正常

Question

我正在使用代码建立蓝牙连接，

public void run() 
{
    try 
    {




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


       // mBluetoothSocket = mBluetoothDevice.createRfcommSocketToServiceRecord(applicationUUID);
        mBluetoothAdapter.cancelDiscovery();

        mBluetoothSocket.connect();





    }
    catch (IOException eConnectException) 
    {
        Log.d(TAG, "CouldNotConnectToSocket", eConnectException);
         closeSocket(mBluetoothSocket);
         return;
    } catch (SecurityException e) {

        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (NoSuchMethodException e) {

        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (IllegalArgumentException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (IllegalAccessException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    } catch (InvocationTargetException e) {
        Log.d(TAG, "CouldNotConnectToSocket", e);
        closeSocket(mBluetoothSocket);
    }
}

它在安卓2.2的Karbonn设备上运行良好，当我在三星Galaxy Y和索尼爱立信Xperia mini上尝试相同的代码时，它不能工作……什么是issue..Kindly辅助...

您在清单中设置权限了吗？

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.BLUETOOTH"/>

你的例外情况到底是什么？

编辑:根据这个http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#ACTION_ACL_DISCONNECTED，这是一个不应该发生的低级异常。

How to programmatically tell if a Bluetooth device is connected? (Android 2.2)这对你有帮助吗？
