Android的：获取蓝牙SDP服务名称 [英] Android: Get Bluetooth SDP Service Name

问题描述

Android的蓝牙API允许您使用注册一个SDP服务：

The Android Bluetooth API allows you to register an SDP service using:

String BLUETOOTH_NAME="MyBluetoothService";
mAdapter.listenUsingRfcommWithServiceRecord(BLUETOOTH_NAME, UUID.fromString(uuid));

它也可以让你启动一个服务Discovey上的远程蓝牙设备，找到现役UUID的名单：

It also allows you to initiate a Service Discovey on a remote Bluetooth Device to find the list of active service UUID's:

device.fetchUuidsWithSdp();

但是，似乎没有可用来获取服务名称的任何公共方法。它可以通过其他途径来获取？

However, there doesn't seem to be any public method available to get the service name. Can it be acquired by other means?

推荐答案

我想你想你会做在Linux中以

I suppose you want to get the names of services running on the device as you would do on a linux box with

浏览的sdptool本地| egrep的服务名称：

sdptool browse local | egrep "Service Name:"

因此​​，答案是否定的，因为没有Android的API方法和命令sdptool是不是在Android上。

So the answer is no, as there is no Android API method and sdptool is not on android.

然而，你可以写AC库使用NDK包含根据功能，并通过JNI调用函数（见蓝牙程序员先上的 http://people.csail.mit.edu/rudolph/Teaching/Articles/BTBook.pdf ）。

However you might write a c library containing an according function using the NDK and call the function via JNI (see Bluetooth for Programmers for the first on http://people.csail.mit.edu/rudolph/Teaching/Articles/BTBook.pdf).

顺便说一句：要列出按名称，而不是由UUID的服务为什么。这是我的经验，服务的名称略有不同，实现的UUID时是可信的。

By the way: Why do you want to list the services by name and not by UUID. It is my experience that service names slightly differ with implementations while UUIDS are credible.
