我如何获得蓝牙设备的UUID？ [英] How do I get the UUID of a bluetooth device?

问题描述

我需要知道的UUID的API 8（2.2）或者可能2.3.3。

据我所知的文档，这应该是允许的：

  phoneDevice = blueAdapter.getRemoteDevice（phoneAddress）;
    ParcelUuid [] phoneUuids = phoneDevice.getUuids（）; //不能编译
 

Eclipse的给我： 的方法getUuids（）是未定义BluetoothDevice类的类型。的 但见： <一href="http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#getUuids">http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#getUuids()

另外，我想知道怎样的UUID被瓜分的ParcelUuid []内。如果我曾经管理到那里，我怎么找回从parcelUuid []一个UUID？文档Android的蓝牙似乎是很差，在我看来。

真是笑话！ 现在，我试着从意图得到它，​​但是这也给了：*EXTRA_UUID不能得到解决或不是场*：

  intent.getParcelableExtra（BluetoothDevice.EXTRA_UUID）;
 

解决方案

您必须使用反射来使用的Andr​​oid版本和LT的getUuids（）和fetchUuidsWithSdp（）; 3.所以，尽量在code：

 方法方法= phoneDevice.getClass（）实现getMethod（getUuids，NULL）;
ParcelUuid [] phoneUuids =（ParcelUuid []）method.invoke（phoneDevice，NULL）;
 

I need to know UUID on API 8 (2.2) or possibly 2.3.3.

As I understand the documentation, this should be allowed:

    phoneDevice = blueAdapter.getRemoteDevice(phoneAddress);
    ParcelUuid[] phoneUuids = phoneDevice.getUuids();  // Won't compile

Eclipse gives me: "The method getUuids() is undefined for the type BluetoothDevice." But see: http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#getUuids()

Also, I would like to know how the UUIDs are "parceled" inside the ParcelUuid[]. In case I ever manage to get there, how do I retrieve a UUID from a parcelUuid[]? Documentation for Android bluetooth seems to be very poor, in my opinion.

What a joke! Now I try to get it from the intent, but this too gives: *"EXTRA_UUID cannot be resolved or is not a field"*:

intent.getParcelableExtra(BluetoothDevice.EXTRA_UUID); 

解决方案

You have to use reflection to use the getUuids() and fetchUuidsWithSdp() on android version < 3. So, try the code:

Method method = phoneDevice.getClass().getMethod("getUuids", null);
ParcelUuid[] phoneUuids = (ParcelUuid[]) method.invoke(phoneDevice, null);
