我正在尝试列出一些在我的Android应用程序中发现的JmDNS服务，每当我调用此方法时，我的应用程序就会在模拟器中崩溃？我试图注释掉代码块和方法内部的代码，但它仍然在模拟器上崩溃。有人有什么想法吗？

您需要相应的用户权限才能检查wifi状态（更具体地说是ConnectivityManager API），将以下权限添加到应用的AndroidManifest.xml中：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<!-- Note that to us JmDNS, you also need the following permissions -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>
试试看，通过阅读代码，您可能还会遇到其他问题。
