致命异常：java.net.UnknownHostException 无法解析主机“maps.googleapis.com”：没有与主机名关联的地址

Question

如何处理这个崩溃？我的项目中没有任何文件 Dns.kt，随机用户崩溃。

Dns.kt 第 49 行 好的http3.Dns$Companion$DnsSystem.lookup

致命异常：java.net.UnknownHostException 无法解析主机“maps.googleapis.com”：没有与主机名关联的地址 java.net.Inet6AddressImpl.lookupHostByName

由 android.system.GaiException 引起 android_getaddrinfo 失败：EAI_NODATA（没有与主机名关联的地址） okhttp3.Dns$Companion$DnsSystem.lookup

Answer 1

尝试将自己的 dns 添加到 okhttp 以捕获异常。我没查。

OkHttpClient.Builder()
    .dns(object : Dns {
        override fun lookup(hostname: String): List<InetAddress> {
            return try {
                Dns.SYSTEM.lookup(hostname)
            } catch (t: Throwable) {
                emptyList()
            }
        }
    })

如果需要，您还可以在此处覆盖主机名的 IP 地址。
