Android的 - 获取蓝牙UUID该设备

问题描述：

我褐变栈和互联网的简单的解决方案来获得设备的我目前使用的 UUID 。我绊了帖子这样但他们都不似乎帮助我。

I was browing Stack and the internet for a simple solution to get the UUID of the device I'm currently using. I stumbled over posts like this but none of them seemed to help me.

doc文件告诉我，about这 getUuids（）的功能，但通过DOC去为的 Android的蓝牙我最终有一个BluetoothAdapter但我需要一个 BluetoothDevice类来执行此功能。

The doc tells me about this getUuids() function but when going through the doc for Android Bluetooth I end up having a BluetoothAdapter but I need a BluetoothDevice to execute this function.

所以，我需要了解以下内容：

So I need to know the following:

1）函数返回真正的设备 UUID ？由于名称甾体抗炎药复数（getUuid 取值）

1) Is the function returning really the device UUID? Because the name saids plural (getUuids)

2）我如何得到这个实例 BluetoothDevice类？

2) How do I get an instance of this BluetoothDevice?

谢谢！

答

使用反射，你可以调用隐藏方法 getUuids（）在 BluetoothAdater ：

Using reflection you can invoke the hidden method getUuids() on the BluetoothAdater:

BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();

Method getUuidsMethod = BluetoothAdapter.class.getDeclaredMethod("getUuids", null);

ParcelUuid[] uuids = (ParcelUuid[]) getUuidsMethod.invoke(adapter, null);

for (ParcelUuid uuid: uuids) {
    Log.d(TAG, "UUID: " + uuid.getUuid().toString());
}

这是在Nexus S的结果：

This is the result on a Nexus S:

UUID: 00001000-0000-1000-8000-00805f9b34fb
UUID: 00001001-0000-1000-8000-00805f9b34fb
UUID: 00001200-0000-1000-8000-00805f9b34fb
UUID: 0000110a-0000-1000-8000-00805f9b34fb
UUID: 0000110c-0000-1000-8000-00805f9b34fb
UUID: 00001112-0000-1000-8000-00805f9b34fb
UUID: 00001105-0000-1000-8000-00805f9b34fb
UUID: 0000111f-0000-1000-8000-00805f9b34fb
UUID: 0000112f-0000-1000-8000-00805f9b34fb
UUID: 00001116-0000-1000-8000-00805f9b34fb

其中，例如， 0000111f-0000-1000-8000-00805f9b34fb 是 HandsfreeAudioGatewayServiceClass 和 00001105-0000-1000-8000-00805f9b34fb 是 OBEXObjectPushServiceClass 。这种方法的实际可用性可能取决于设备和固件版本。

where, for instance, 0000111f-0000-1000-8000-00805f9b34fb is for HandsfreeAudioGatewayServiceClass and 00001105-0000-1000-8000-00805f9b34fb is for OBEXObjectPushServiceClass. Actual availability of this method may depend on device and firmware version.
