Problem: javax.net.ssl.SSLProtocolException: SSL handshake-Failure in SSL library,

[Carlos Fernando Gonçalves]

Hi all.

Please me.

I am using the ksoap2 library.
A problem with TLS 1.2 certificate.
In the emulator, OK works.
But when I try to run App on Samsung Galaxy with Android 4.4.2 API level 19, this error occurs:

javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x62d0c960: Failure in SSL library, usually a protocol error
error:14077102:SSL routines:SSL23_GET_SERVER_HELLO:unsupported protocol (external/openssl/ssl/s23_clnt.c:714 0x5e5af7e8:0x00000000)

Please,
if anyone has any tips, I am very grateful.

Best regards,
Carlos
