This class uses GMailSender class to set the sender email id, password.
using addAttachment method we specify path of file to be attached.
sendMail has four parameters namely subject, body text, senders name, recipients.
Add appropriate file path depending on device and a valid one.
Add Android manifest.xml
Add Jar for mail
