模拟器挂起，未连接到互联网时不显示任何错误

Question

当互联网与我的笔记本电脑断开连接时，模拟器出现问题。有时，甚至菜单按钮也没有作用。 Agian立即开始工作，笔记本电脑连接到互联网。 Internet断开连接时，Connectivity.isConnected（）方法在模拟器上是否有任何问题。请让我知道是否有类似问题。

在尝试使用菜单选项的日志中连接到互联网后，出现以下错误消息：

您不应从启动/初始化开始使用该API。它可能在检查时阻止并有效地使您的应用崩溃。 start / init方法需要彻底完成执行。

组件检查器无法处理EDT线程，因此它违反了它。对于生产来说，这并不重要，因为您的设备上没有组件检查器...
