Android Question POP3 GMail reading problem. (Solved)

[ELCHARO]

HI.

I use this code to read mail. Enter in the server and read 6 mails.

log this Leyendo Mail, de1de17
( 1 of 17)
if run again not begin in the first of 17
log this Leyendo Mail, de1de11
( 1 of 11)

In the web gmail the mail remains 17 , never delete

What happens. How begin reading for first newer mail again?
I continue go to 0 mail, but are 17 in the server.
Of course, run only when new mail arrives (if enter 5 over 17) , see only 5 in the app.
Is a gmail account
("Server","pop.gmail.com")
("Port","995")


I try like activity ,and try like a service. And have the same problem.
Somebody know why?


Thanks
