我收到以下错误。该程序应该打印它从在线 wsdl 访问的值。但它不打印任何内容，并且 LogCat 中出现以下错误：

这里发生的事情通常是由活动和服务之间的绑定引起的。该活动已停止，因此系统认为不再需要该服务并可能停止该服务，从而导致该错误。

快速解决方法是添加unbindService(mConnection); 在您的 onstop() 或 onDestroy() 方法中。

如果你想让服务在启动它的活动被销毁后仍然运行，你应该首先使用startService。

ComponentName myService = startService(new Intent(this, myClass.class));
bindService(new Intent(this, myClass.class), myServiceConn, BIND_AUTO_CREATE);

来自 Android 文档：

对于startService：

使用 startService() 会覆盖由 bindService(Intent, ServiceConnection, int) 管理的默认服务生命周期：它要求服务在调用 stopService(Intent) 之前保持运行，无论是否有任何客户端连接到它。

对于绑定服务：

只要调用上下文存在，系统就会认为该服务是必需的。例如，如果这个 Context 是一个停止的 Activity，那么在 Activity 恢复之前，服务将不需要继续运行。
