Following this one: https://developer.android.com/intl/es/training/articles/security-ssl.html part:Unknown certificate authority - example of University of Washington.
Now I can access and communicate with the server. I got the response from the server as expecting. However, there are some error on Android log:
E/NativeCrypto﹕ ssl=0x61ede338 cert_verify_callback x509_store_ctx=0x618358c0 arg=0x0
E/NativeCrypto﹕ ssl=0x61ede338 cert_verify_callback calling verifyCertificateChain authMethod=RSA
I don't have any ideas where this comes from? Is this normal? Someone can explain/help me out please?
