Sorry for my english!
I get a error when I try to send an e-mail from my gmail account, with the JavaMail API in Android.
I get this error: AuthenticationFailedException.
I tried following:
the email address with the password are correct (I tested also with an another mail address).
The settings in google are correct.
I tested with port 465, then I get another exception.
I have searched for 3 days on the internet and have found nothing that has helped.
