Question

我正在尝试实施从http://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/analytics.html

获得的AWS Mobile Analytics的入门代码

我在清单中设置了所有设置以及Internet权限，但在所有调试和故障排除后我仍然收到此错误。

我尝试过使用ConnectivityManager和InetAddress.getByName（“google.com”）。isReachable（3）来确认我的代码能够访问互联网。

到目前为止，我的假设是以某种方式调用的主机名是错误的。它应该是“mobileanalytics.us-east-1.amazonaws.com”而不是“mobileanalytics.us-east-1”。。否则可能是防火墙问题或https，我必须进一步探讨。我在移动设备上使用wifi连接。

有任何帮助指针吗？

看起来这是AWS Mobile SDK v2.1.9的已知错误。

阅读@ Yangfan的评论看起来已经在2.1.10版中解决了
