FATAL EXCEPTION when using okhttpclient with conscrypt

See original GitHub issue

I want tls 1.3 so I use conscrypt, according to TestTls13Request.java I use : Security.insertProviderAt(Conscrypt.newProviderBuilder().provideTrustManager().build(), 1) but it crashed, here is log

AndroidRuntime: java.lang.NoClassDefFoundError: org.conscrypt.TrustManagerImpl
AndroidRuntime: 	at org.conscrypt.TrustManagerFactoryImpl.engineGetTrustManagers(TrustManagerFactoryImpl.java:87)
AndroidRuntime: 	at javax.net.ssl.TrustManagerFactory.getTrustManagers(TrustManagerFactory.java:219)
AndroidRuntime: 	at okhttp3.internal.Util.platformTrustManager(Util.java:667)
AndroidRuntime: 	at okhttp3.OkHttpClient.<init>(OkHttpClient.java:257)
AndroidRuntime: 	at okhttp3.OkHttpClient$Builder.build(OkHttpClient.java:1040)

There is no excepiton if I use this instead: Security.insertProviderAt(new org.conscrypt.OpenSSLProvider(), 1); but okhttpclient use tls 1.2 to handshake not 1.3

@yschimke Well, it doesn’t work. At least not out of the box. I’ll post to StackOverflow.

I’d rather not use proprietary close source components like Google Play Services; I’m fine for now if TLSv1.3 only works on Android 8 and 9.
