我使用exchangelib从python中的kivymd访问我的邮件。当我在计算机上运行我的代码时，它工作起来没有问题。但是，当我在Android上通过buildozer部署它并在Android上启动我的应用程序时，我看到了解析器错误。请帮忙，我不明白问题的根源。

exchangelib需要进行DNS查找才能使自动发现工作。NoResolverConfiguration是dnspython包中的一个例外，它告诉您在系统中找不到任何关于要联系哪些名称服务器的信息。通常，这将位于/etc/resolv.conf中，如FileNotFoundError错误所示。
我不知道DNS在安卓系统上是如何工作的，也不知道Python如何访问安卓系统的DNS配置。如果无法让dnspython获取配置，可以在Resolver.nameservers属性中手动设置要使用的DNS服务器列表(例如[8.8.8.8](。您可以在exchangelib中通过Autodiscovery.DNS_RESOLVER_ATTRS属性对此进行配置：
from exchangelib.auto discover import Autodiscovery
Autodiscovery.DNS_RESOLVER_ATTRS['nameservers'] = ['8.8.8.8']
