推荐答案
通过阅读到Android源$ C $ C，这似乎是一个警告你不能做任何事情。该人士$ C $ C表明，如果你调用
By reading into the Android source code, it seems to be a warning you cannot do anything about. The source code shows that if you call
BluetoothSocket#connect();
然后，它会调用
Then it will call
BluetoothAdapter.getDefaultAdapter().getBluetoothService(null);
这里的关键是，它通过在上述线的空参数。由于这个原因，就没有回调，然后的BluetoothSocket类将抛出一个警告。
The key here, is the null parameter that it passes in the above line. Due to this, there will be no callback, and then the BluetoothSocket class will throw out a warning.
由于这只是一个警告，我不认为你需要做任何事情。
Since it is only a warning, I do not think you need to do anything about it.
