我正在尝试在 Android （GT-I5700 上的 2.1-update1）手机上打开蓝牙服务器套接字，但它失败了。我已经没有想法了。欢迎对我所缺少的内容提出一些建议。蓝牙已打开，所以这应该不是问题。

我也很确定权限没问题：

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

失败的代码非常简单：

String TAG = "MYAPP";
UUID UUID_RFCOMM_GENERIC = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
BluetoothSocket s;
BluetoothServerSocket bss;
try {
    Log.i(TAG, "We do reach this point");
    bss = adapter.listenUsingRfcommWithServiceRecord("PrettyService", UUID_RFCOMM_GENERIC); 
    Log.i(TAG, "We never reach this");
    s = bss.accept();
} catch (IOException e) {
    Log.i(TAG, "Blutooth failed");
}

和日志：

这个错误非常难看，谷歌搜索什么也没有。我对整个 Android 世界也很陌生。
