早些时候，在解析数据时，我从来没有得到过这样的Exception，但是今天我突然得到了TAG mismatch Exception。我不知道我哪里弄错了。请帮帮我。

最后，经过这么长时间的斗争，终于找到了解决办法。我的问题是我的Wifi连接。它没有连接到经过验证的Wifi连接。因此，要检查Wifi是否启用或禁用，请运行以下代码:您可以注册一个BroadcastReceiver，以便在建立WiFi连接时得到通知(或者连接是否更改)。注册BroadcastReceiver：

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
registerReceiver(broadcastReceiver, intentFilter);

And then in your BroadcastReceiver do something like this:

@Override
public void onReceive(Context context, Intent intent) {
    final String action = intent.getAction();
    if (action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION)) {
        if (intent.getBooleanExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED, false)){
            //do stuff
        } else {
            // wifi connection was lost
        }
    }
}
