[Android] interactive demo with PHP sessions, androidsession

Jump from MainActivity to MailIndexActivity. The first request interface sets the session, and the second activity requests the interface to get the session

Get the Set-Cookie in the header in java code

When a request is sent, set the header information Cookie, which is equivalent to obtaining the session from the browser.
