Subject: Apache HTTP to Android HttpsURLConnection started.

SRP parameter A tries to be sent via HttpsURLConnection. Right now, we
have a problem with certificates because I'm not using provider CA cert
to get the response. I'm going to merge the branch with better method
names to download response using already existing code.
