【问题描述】：
大家好！
当我通过蓝牙连接嵌入式设备时遇到问题。 当我使用此代码连接时：
public void run() {
Looper.prepare();
try {
// Connect the device through the socket. This will block
// until it succeeds or throws an exception
mmSocket.connect();
if(!cancel){
toMain = threadhandler.obtainMessage();
toMain.arg1 = 1;
threadhandler.sendMessage(toMain);
}
} catch (SecurityException e) {
if(!cancel){
Log.e("SecurityExcep", "Oh noes" , e);
toMain = threadhandler.obtainMessage();
toMain.arg1 = 2;
threadhandler.sendMessage(toMain);
Log.w("MESSAGE", e.getMessage());
}
}catch (IOException e) {
//Bad connection, let's get the hell outta here
try {
Log.e("IOExcep", "Oh noes" , e);
Log.w("MESSAGE", e.getMessage());
if(!cancel){
mmSocket.close();
toMain = threadhandler.obtainMessage();
toMain.arg1 = 2;
threadhandler.sendMessage(toMain);
}
return;
} catch (IOException e1) {
Log.e("IOExcep2", "Oh noes" , e);
}
}
try {
mmSocket.close();
} catch (IOException e) {
Log.d("CONNECT_CONSTRUCTOR", "Unable to close the socket", e);
}
if(!cancel){
toMain = threadhandler.obtainMessage();
toMain.arg1 = 3;
threadhandler.sendMessage(toMain);
}
Looper.loop();
return;
// Now it should be paired.. only thing to do now is let the user commit to the rest
}
我搜索设备，找到它，然后通过mmSocket.connect() 连接它。之后，请求被发送到我输入PIN 的嵌入式设备。之后，如果我收到通知说设备正在尝试配对等，请求就会发送到手机。
首先，它不应该是通知！它应该是一个对话，我 猜猜这不是我的错。
其次，为什么我在收到通知约 20 秒后收到以下异常：
