java.net.UnknownHostException 无法解析主机“accounts.google.com”：在 bigquery 中插入行时没有与主机名关联的地址

android java google-api-java-client google-api-client google-bigquery

嗨，我正在开发Android应用程序，其中我集成了BigQuery。我看到我们有时会在BigQuery表中插入记录时遇到很多异常。我们不是这方面的专家，而是开始学习这项新技术。如果你们能帮我，那就太好了。

答案 1

此异常抛出，表示无法确定主机的 IP 地址。

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。它很容易重现这个：

连接到有效的wifi现在在插入路由器时从路由器上取下电缆

你会观察到这个错误！！

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”）

还要确保已在中添加了权限。AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />

答案 2

您是否已将 INTERNET 权限添加到清单文件中。

如果没有，请在您的应用程序标记外添加以下行：AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
