Question

尝试使用带有Custom Phone - 7.0.0 - API 24 - 768x1280 - 7.0的Genymotion 2模拟器以及通过USB MotoG3 - 6.0.1插入的真实设备。

在这两种情况下，对外部托管的工作JSON API进行提取失败。

同样适用于ios模拟器。

以下报告的问题没有帮助 https://github.com/facebook/react-native/issues/5222 https://github.com/facebook/react-native/issues/15100

我的问题是（我知道java但不够Android） - 我在哪里查找任何日志/例外以了解它失败的真正原因。因为API本身是有用的，并且正在使用IOS模拟器。

我必须编写一个Android HelloWorld应用程序才能进入javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found
