java.net.UnknownHostException Unable to resolve host "accounts.google.com": No address associated with hostname while inserting rows in bigquery
提问by N Sharma
Hi I am working on android app in which I have integrated BigQuery. I see we are getting a lot of exception sometimes while inserting records in BigQuery tables. We are not expertise in this but started to learn this new technology. It would be great if you guys can help me on this.
嗨，我正在开发集成了 BigQuery 的 android 应用程序。我看到我们在 BigQuery 表中插入记录时有时会遇到很多异常。我们不是这方面的专业人士，而是开始学习这项新技术。如果你们能在这方面帮助我，那就太好了。

This Exception Thrown to indicate that the IP address of a host could not be determined.
抛出此异常表示无法确定主机的 IP 地址。
This exception is also raised when you are connected to a valid wifi but router does not receive the internet. Its very easy to reproduce this:
当您连接到有效的 wifi 但路由器未接收互联网时，也会引发此异常。很容易重现这个：
Connect to a valid wifi Now remove the cable from the router while router is pluged-in
连接到有效的 wifi 现在在插入路由器时从路由器上拔下电缆
You will observe this error!!
你会观察到这个错误！！
You can't really solve this, You can only notify the user gracefully. (something like - "Unable to make a connection")
你不能真正解决这个问题，你只能优雅地通知用户。（类似于 - “无法建立连接”）
also make sure you have added the permission in AndroidManifest.xml.
还要确保您已在AndroidManifest.xml.
<uses-permission android:name="android.permission.INTERNET" />
