我的小部件更新服务正在抛出: 当我尝试从我的Web服务器获取SOAP响应时,“android.os.NetworkOnMainThreadException”。
我确信SOAP代码没有错误,因为我只通过IntentService而不是Service使用应用程序中的相同代码。
我根据最后一个例子设计了我的小部件:http://www.vogella.com/tutorials/AndroidWidgets/article.html

这是您应用的安全问题,因为在应用主线程上执行网络操作会阻止所有其他应用操作。重构您的Service
以使用后台线程来执行网络操作并为您的小部件提供结果。您可以使用AsyncTask
来获得此功能,或者使用您自己的线程池等等。
