Hi devs. I am trying to establish SSL connection between android and java
server running on windows using SSLSockets. But i am not able to get the
connection into working.
I am nowhere good in SSL connection and lost in establishing connection. So
any pointers on how it should be done between android and java server ?
I have attached the code that i have tried. Can anyone find out where i am
going wrong ?
Here is the stacktrace.
