代码如下，测试发现toast直到“mmsocket成功”都是有的，mmSocket.connect(); 那失败了，抛出“连接服务端异常2”
protected void onResume() {
if(BluetoothMsg.isOpen)
{
Toast.makeText(mContext, "连接已经打开，可以通信。如果要再建立连接，请先断开！", Toast.LENGTH_SHORT).show();
return;
}
// 如果点选了远程设备去连接，则本机是客户端， 开启客户端线程，接收输入流数据
if(BluetoothMsg.serviceOrCilent==BluetoothMsg.ServerOrCilent.CLIENT)
{
String address = BluetoothMsg.BlueToothAddress; //将在UI界面选中连接的蓝牙地址赋给address
if(!address.equals("null")) //如果蓝牙地址不为空
{
//在mainactivity中的get到的本地蓝牙适配器实例化成了blueadapter，在这个activity中在开头实例化成了 mBluetoothAdapter，但是它们是同一个
device = mBluetoothAdapter.getRemoteDevice(address);//根据蓝牙地址获取远程蓝牙设备
// mBluetoothAdapter.cancelDiscovery();
if (device != null) {
Toast.makeText(mContext, "device成功 !", Toast.LENGTH_SHORT).show();
}
clientConnectThread = new clientThread(device); //新建并启动一个客户端线程
clientConnectThread.start();
BluetoothMsg.isOpen = true; //将BluetoothMsg类里的isOpen常量改为true
}
else
{
Toast.makeText(mContext, "蓝牙地址为空 !", Toast.LENGTH_SHORT).show();
}
}
// 如果本机是服务器，开启服务端线程，也接收输入流数据
else if(BluetoothMsg.serviceOrCilent==BluetoothMsg.ServerOrCilent.SERVICE)
{
}
super.onResume();
}
//2开启客户端 读取数据
private class clientThread extends Thread
{
private final BluetoothSocket mmSocket;
