"SSL error: The certificate authority is not trusted" opening web view with proguard enabled

[mmartinelliGC]

Getting the error "SSL error: The certificate authority is not trusted" in my react-native android project when opening any url in a webview. It only happens when proguard is enabled. I tried adding the following suggested in #41 to my proguard-rules file, but that didn't change anything.

-keep class com.appmattus.certificatetransparency.internal.verifier.CertificateTransparencyTrustManager { *; }

I'm getting a slightly different error so I'm not sure they are related. Any help would be appreciated. Thanks

I've been investigating this myself as well. I see the following whenever I open a webview:

Hi, I've faced with the same issue..., tried the latest version of the library

[dsatija]

@Sar777 i was able to resolve this by adding below in proguard file:

-keep class com.appmattus.certificatetransparency.internal.verifier.CertificateTransparencyTrustManagerExtended { public ;}
-keepclassmembers class com.appmattus.certificatetransparency.internal.verifier.CertificateTransparencyTrustManagerExtended {
public java.util.List checkServerTrusted(java.security.cert.X509Certificate[], java.lang.String, java.lang.String);
}
-keepclassmembers class com.appmattus.certificatetransparency.internal.verifier.CertificateTransparencyTrustManagerExtended {;}
