Android的 - 获取蓝牙UUID该设备 [英] Android - Get Bluetooth UUID for this device

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，<一个href=\"http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#getUuids%28%29\">about这 getUuids（）的功能，但通过DOC去为的 Android的蓝牙我最终有一个<一个href=\"http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html\">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！

推荐答案

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.
