望你踩呐我的回答
下面是自动配对的代码

⑵ Android蓝牙开发代码怎么写
开启蓝牙设备和设置可见时间：
privatevoidsearch(){
BluetoothAdapteradapter=BluetoothAdapter.getDefaultAdapter();
if(!adapter.isEnabled()){
adapter.enable();
}
Intentenable=newIntent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
enable.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION,3600);//3600为蓝牙设备可见时间
startActivity(enable);
IntentsearchIntent=newIntent(this,ComminuteActivity.class);
startActivity(searchIntent);
}首先，需要获得一个BluetoothAdapter，可以通过getDefaultAdapter()获得系统默认的蓝牙适配器，当然我们也可以自己指定，但这个真心没有必要，至少我是不需要的。然后我们检查手机的蓝牙是否打开，如果没有，通过enable()方法打开。接着我们再设置手机蓝牙设备的可见，可见时间可以自定义。

⑶ 谁能给一份开发基于蓝牙4.0的android的demo源码
请参考如下WIKI页面，基本上目前有提供的BLE的参考代码都集中到这个页面了：http://processors.wiki.ti.com/index.php/Category:BluetoothLE
⑷ 如何实现android蓝牙开发 自动配对连接，并不弹出提示框
我就开始查找怎么关闭这个蓝牙配对提示框，后面还是伟大的android源码帮助了我。
在源码 BluetoothDevice 类中还有两个隐藏方法
cancelBondProcess（）和cancelPairingUserInput（）
这两个方法一个是取消配对进程一个是取消用户输入

⑸ 关于android系统蓝牙都用什么模块，有单独的android驱动吗
Android系统的源码中蓝牙部分的分布式这样的：
1. App部分主要包括OPP和PBAP以及HFP，当然还有settings部分，代码分布如下：
(1) /packages/app/Bluetooth/src/com/android/bluetooth/opp
(2) /packages/app/Bluetooth/src/com/android/bluetooth/pbap
(3) /packages/app/Phone/src/com/android/phone/ 中和BT相关的部分，主要是HFHS打电话相关的
(4) /packages/app/Settings/src/com/android/settings/bluetooth/ 主要是蓝牙开启，搜索，配对等
2. Framework部分主要包括BluetoothAdapter,BluetoothService，BluetoothEventLoop，BluetoothA2dpService等核心类，代码分布如下：
(1)/frameworks/base/core/java/android/server/ 包含BluetoothService，BluetoothEventLoop等核心类，但是并没有向用户应用程序提供接口，属于系统的类。
(2)/frameworks/base/core/java/android/bluetooth 包含了BluetoothAdapter, BluetoothSocket, BluetoothServerSocket等一系列类，这些类是系统向应用程序提供的接口，编写蓝牙相关的应用程序时会用到这些类，检查BT是否打开，搜索设备等等。如果编写蓝牙应用程序，需要熟悉该部分类的功能。
(3) /frameworks/base/core/jni/ 中包含Bluetooth相关的文件，如 android_server_BluetoothService.cpp 该部分主要是java层和c/c++层进行通信的
3. Bluez部分，主要包括各个协议的实现，如A2dp，AVRCP，AVDTP，HID，HDP，PAN，DUN以及对BT host的实现，通过该部分向BT Controler部分发送HCI命令，代码分布服下：
/external/bluetooth/bluez
4. BluetDroid部分，主要用于开关蓝牙，芯片上电部分（不属于驱动，可以算是硬件抽象层（HAL））， 代码分布如下：
/system/bluetooth/
5. kernel部分，主要包括RFCOMM，L2CAP等协议以及HCI的实现，代码分布如下：
/kernel/net/bluetooth/
6. driver部分，该部分代码还真没了解过，代码分布：
/kernel/drivers/bluetooth/
另外，driver部分和具体芯片密切相关，有时在下面的目录下也会有：
/vendor/
/device/
⑹ 求android 蓝牙开发的示例代码 主要是怎么搜索其他设备 然后以列表的形势显示出来，急求~！！！
看源码就行了，很简单的。

⑻ 求安卓Android手机上的的蓝牙串口通讯源码！！！！
http://code.eoe.cn/789?f_section=new
以上是地址 自己去下
⑼ android_studio手机蓝牙串口通信源代码
初涉android的蓝牙操作,按照固定MAC地址连接获取Device时，程序始终是异常终止，查了好多天代码都没查出原因。今天改了一下API版本，突然就成功连接了。总结之后发现果然是个坑爹之极的错误。
为了这种错误拼命查原因浪费大把时间是非常不值得的，但是问题不解决更是揪心。可惜我网络了那么多，都没有给出确切原因。今天特此mark，希望后来者遇到这个问题的时候能轻松解决。
下面是我的连接过程，中间崩溃原因及解决办法。
1：用AT指令获得蓝牙串口的MAC地址，地址是简写的，按照常理猜测可得标准格式。
2：开一个String adress= "************" //MAC地址， String MY_UUID= "************"//UUID根据通信而定，网上都有。
3：取得本地Adapter用getDefaultAdapter(); 远程的则用getRemoteDevice(adress)； 之后便可用UUID开socket进行通信。
如果中途各种在getRemoteDevice处崩溃，大家可以查看一下当前的API版本，如果是2.1或以下版本的话，便能确定是API版本问题，只要换成2.2或者以上就都可以正常运行了~ 这么坑爹的错误的确很为难初学者。 唉·········· 为这种小trick浪费很多时间真是难过。
（另外有个重要地方，别忘了给manifest里面加以下两个蓝牙操作权限哦~）

⑽ Android源码中有关蓝牙配对的程序在哪些文件中
你是用的蓝牙2.0，还是4.0 BLE？不管是这两者中哪一个，android SDK都有相关sample可以学习使用，从搜索设备，建立连接，到两端的通信都有，基本覆盖我们要使用的所有功能。
2.0的sample是：BluetoothChat，里边有3个.java文件，网上对它的相关讲解很多，你可以参考blog.csdn.net/homebei2/article/details/6078007；
4.0的sample是：BluetoothLeGatt，如果我没记错的话，里边有4个.java文件，因为google在android4.3才支持BLE的api，相对来说比较新，用的话主要是理解一些新的协议栈概念，不是很难，网上资料相对来说少些，你也可以找找看
