蓝牙高手进！wsock error的问题
各位大神们，小生的毕设是android平台，蓝牙通信+数据库的应用，眼看程序渐渐转安，却发现了百度不得其解，我连英文google都用上了，却什么都查不到的错误。##### ERROR : wrp_wsock_create: wrp_sock_create : out of wsock blocks#####
解释一下程序的流程，UI线程调用一个子线程来负责传输，子线程先搜索10秒，把搜索到的设备都存到ArrayList里，然后结束搜索，开始对每一个发现的设备进行uuid检验，uuid是通用设备的00001101-0000-1000-8000-00805F9B34FB，然后connect()，成功后调用另一个子线程来负责这个设备的传输，为了保证没有阻塞进程的发生，这里将该线程进行了join(5000)，即阻塞5秒结束，然后开始下一个设备的传输，如果所有设备都结束了，等15秒，重新开始该过程。
测试是只有一个可传输设备和一个“哑”设备，问题在刚开始运行是不会出现，大概进行了6-7次循环后，就会出现那个错误，会导致uuid检验抛出异常，连接也就不可能被执行到了，而且一出错误就一直有，再也恢复不了了……
个人推测：
这个wsock block是个什么空间，用来存和蓝牙相关的什么东西，可能是socket，太多了就溢出了，用不了了，难道是我socket关闭的不正确？uuid检验的异常抛出条件是，蓝牙设备不可用或不足权限。
相关代码：
一个由UI线程调用的子线程的run中的一部分：
while(true){
//searching section
possibleDevices.clear();
//searching section
if(!bluetooth.isDiscovering()){
Log.i(TAG, "start discovery: "+bluetooth.startDiscovery());
//bluetooth.startDiscovery();
try {
sleep(10000);//搜索10秒
} catch (InterruptedException e) {
e.printStackTrace();
}
Log.i(TAG, "cancel discovery: "+bluetooth.cancelDiscovery());
//bluetooth.cancelDiscovery();
}else{
Log.i(TAG, "cancel discovery 2");
bluetooth.cancelDiscovery();
}
//wait for cancel discovery，不知道有没有用
try {
sleep(500);
} catch (InterruptedException e1) {
Log.i(TAG, "wait for cancel discovery failed: InterruptedException");
}
//connecting section
for(BluetoothDevice oneDevice:possibleDevices){
oneSocket = null;
try {
oneSocket = oneDevice.createRfcommSocketToServiceRecord(uuid);
if(oneSocket != null){
try{
oneSocket.connect();
Log.i(TAG, "one socket connected");
try {
ConnectOne connectOne = new ConnectOne(oneSocket);
connectOne.start();
connectOne.join(5000);
if(connectOne.isAlive()){
connectOne.interrupt();
}
} catch (InterruptedException e) {
Log.i(TAG, "one connection time out: InterruptedException");
}finally{
try {
oneSocket.close();
Log.i(TAG, "one socket closed");
} catch (IOException e1) {
Log.i(TAG, "one socket close failed: IOException");
}
}
} catch(IOException e) {
Log.i(TAG, "connect failed: IOException");
}
}
} catch (IOException e) {
Log.i(TAG, "uuid failed: IOException"); //一报错这里就开始catch了
continue;
}
}
try {
sleep(15000); //time consuming
} catch (InterruptedException e) {
Log.i(TAG, "protection failed: InterruptedException");
}
}
上述部分用到的ConnectOne线程：

--------------------编程问答-------------------- 问一下 ，蓝牙自动配对，这个您会吗？如果可以能不能发一份代码，谢谢啊，我的qq1149598411 --------------------编程问答-------------------- 贴主，可以加我QQ928161785. --------------------编程问答-------------------- 我在这里有个回复，希望能帮到你，The "out of wsock blocks" happens because there is a leak in Android when creating sockets, so after trying too much, it will run out of sockets, you need to reboot and then you will get another error message.
