我似乎无法上传Crashlytics的映射文件。我做了提到的所有内容here，并且收到崩溃报告。但是崩溃报告被混淆了。
我确定我的互联网连接正常。创建发行版本时，会看到以下警告：

我还为dexguard and proguard添加了其他配置。但是我没有看到任何-printmapping mapping.txt，并且仍然生成了映射文件。但是，这对我来说似乎不是问题。
我也没有看到Crashlytics的任何日志文件，如this answer中所述。
有人知道如何解决此问题吗？
编辑：我发现了Crashlytics日志记录。我可能看错了位置。看起来Crashlytics正在使用我的某些代理设置，而目前我还没有落后于代理。 com.crashlytics - Crashlytics using custom proxy settings:。我将尝试以某种方式编辑这些设置。
问题是，即使我没有代理，Android Studio仍保留我的代理设置。重新启动Android Studio并执行构建后，映射文件已成功上传。 Crashlytics日志记录是解决此问题的关键。
但是我还需要它在代理之后工作，并且出现某种证书错误。我将为此发布一个不同的问题。
