所以我遵循了 Firebase Android Crashlytics 指南，但发生了这种情况：
E/FirebaseCrashlytics: Settings request failed.

我尝试了发布和调试版本，两者都不起作用。我需要做什么指南没有提到的事情？
有同样的问题。通过禁用任何广告拦截器即可解决
这看起来不像 Crashlytics 问题，而是证书问题。我建议看一下这个线程 android java.security.cert.CertPathValidatorException: Trustanchor for Certification Path not found.
就我而言，这是由 NextDNS.io 引起的，它阻止了 Crashlytics 请求。
您可以将以下域列入白名单：
*.firebase-settings.crashlytics.com*.crashlyticsreports-pa.googleapis.com就我而言，原因是在 Android 模拟器上使用代理服务器（我使用 Charles）。 我刚刚将服务器添加到“绕过代理”部分（在模拟器上的 WiFi 设置中）。服务器地址可以在 Charles 找到。 或者你可以直接禁用代理。
