android - Crashlytics 初始化连接异常 (EHOSTUNREACH)

Question

我在 Android 应用程序上安装了 Crashlytics SDK(通过 Fabric)，它之前运行良好。突然之间，我收到了 ConnectionExceptions 并且 Crashlytics 无法与其远程服务器通信。

Fabric 在我的 Application 类的 onCreate 结束时被实例化:

public void onCreate() {
  super.onCreate();
  ...
  Fabric.with(this, new Crashlytics());
}

这是应用程序启动时的堆栈跟踪。有什么想法吗？

Answer 1

我想我找到了问题所在。这些错误似乎只在我使用本地 Second Cup wifi 网络时发生。当我使用我的家庭网络时，它工作得很好。

这里一定有某种代理问题。
