关于虚拟设备与Android APP数据收发
[*]情况描述
APP发送控制指令虚拟设备不响应
发送指令的回调会被调用，但是，回调的结果不对
@Override
public void didReceiveData(XPGWifiDevice device,
ConcurrentHashMap<String, Object> dataMap,
int result){
。。。
}如上所示，回调函数的3个参数里面，dataMap为空，result值为-20
经查API，-20对应的错误代码为
public static final int XPGWifiError_INVALID_PARAM -20 但是，我发送数据的格式
int GWifiDevice::write(char const*): {"entity0":{"Switch":"1"},"cmd":1}跟IOE Demo发送数据的格式
int GWifiDevice::write(char const*): {"entity0":{"Switch":"1"},"cmd":1}是完全一样的
但是，IOE Demo发送的控制指令虚拟设备完全能够正常响应
另，虚拟设备推送的数据也无法正常接收，接收到的结果值为213，我不知道这个213代表什么，我也不知道这是不是代表接收成功，但是日志的确没有像正常接收数据那样打印接收到的json格式的数据包
下面附上程序运行日志，各位大大帮帮忙看看我的问题出在哪里

此日志的过滤条件是22717，即线程号，所以不用担心有用的信息会被过滤掉
[*]相关代码
发送数据的代码段：
if(device.isOnline()){
try{
final JSONObject jsonsend = new JSONObject();
jsonsend.put("cmd", 1);
JSONObject jsonparam = new JSONObject();
jsonparam.put("Switch", "1");
jsonsend.put("entity0", jsonparam);
device.write(jsonsend.toString());
}catch(JSONException e){
e.printStackTrace();
}
}else{
Toast.makeText(DeviceListActivity.this, "Error:Device Is Not Online !", Toast.LENGTH_SHORT).show();
}

相关回调：
@Override
public void didReceiveData(XPGWifiDevice device,
ConcurrentHashMap<String, Object> dataMap,
int result){
Message msg = Message.obtain();
//msg.obj = "Data Received Success";
if(result == -20){
msg.obj = "INVALID PARAMS";
}else{
msg.obj = "Other Error"+result;
}
msg.what = DATA_RECEIVE;
mcHandler.sendMessage(msg);
}; // end of didReceiveData
[*]PS：我的SDK是昨天升级的，升级之前是收不到这个回调的，因为我不知道SDK具体更新了什么，相关代码也不知道该修改哪里，也许这是个线索

ERROR_INVALID_PARAM 出错的可能性，只有两个。一个是设备为空，一个是写入的数据为 null。看了你的原帖 ...
这才是正解！！！:victory:终于找到原因了！！！
感谢 bool GWifiDevice::IsBind(char const*)():760, device VIRTUAL:SITE is not bind to uid 404884c5a668434ebb552e15143a4e55, because the cache uid is empty.
这里，我发现了问题，但是不知道是怎么回事，字面意思是绑定没有成功，但是，isBind(uid)却通过了。。。
API里面说这个方法返回的是true或false，通过了应该是绑定成功了啊，那这句日志是怎么回事呢？ v1.3.0.15082322这个版本的设备绑定有bug，下个版本已经修复，本周会发布到官网。 pomia 发表于 2015-9-1 14:43

设备没有与这个 uid 绑定，才会有这个 log 打印。IsBind() 方法应返回 false。你说的通过了是返回 TRUE 吗？ Tom 发表于 2015-9-3 20:40

ERROR_INVALID_PARAM 出错的可能性，只有两个。一个是设备为空，一个是写入的数据为 null。看了你的原帖，写入数据格式没错。那么，能登录成功，设备也不会为空。有一种情况，设备登录之后，再调用获取设备列表，这样会有问题。我想问一下，你的 app 是否是这样做的？ MalcolmC 发表于 2015-9-6 12:37
但是poima告诉我那个输出是正常的。。。
虚拟设备，在当前用户能得到列表，并且包含这个设备，我们认为这个设备是已经绑定的，则 IsBind 返回 true。出现没有绑定的日志，根据源码上得出 IsBind() 一定是返回 false。 本帖最后由 Tom 于 2015-9-6 23:45 编辑
SDK 的做法是，IsBind 传入的 uid 会比对缓存的 uid 是否一致。如果一致，则为绑定成功。这个缓存的 uid，是最后一次登录、使用对应的 uid、token 获取设备列表的时候，SDK 会自动记录的一个值。 再讲细一点吧
bool GWifiDevice::IsBind(char const*)():760, device VIRTUAL:SITE is not bind to uid 404884c5a668434ebb552e15143a4e55, because the cache uid is empty.
这个日志出现的原因，是因为 SDK 缓存的 uid 是空的。出现这种情况，device.IsBind() 返回一定为 false。
