android 取消蓝牙配对框 实现自动配对

2012-08-31

我看了几个文章,主要是接受配对广播,然后设置pin,实现配对,但是网上的大部分手机是不可以的,android.bluetoothdevice 下 action_pair_request ,没有定义这个,开始困扰了我一点时间,实现难度:是否能进入...

我看了几个文章,主要是接受配对广播,然后设置pin,实现配对,但是网上的大部分手机是不可以的,android.bluetoothdevice 下 action_pair_request ,没有定义这个,开始困扰了我一点时间,实现难度:是否能进入那个广播响应

定义了一个类,这个是网上的可以直接用
