Issue
Good morning, thanks and sorry for my english!
I'm working in an android app, i want that the app send a lot of sms with SmsManager. That's fine, but the problem its when i try to implements any type of beetween the sending of each sms. I tried with Thread inside the for, asynctask too, but the app go to sleep too, and i need that the app doesn't block while i'm sending the sms.
I read the numbers of an external (inside the app directory) file, then i put that datas inside a HashTable, and i do a for loop to call the SmsManager function, sendTextMessage.

Solution
In the end, I've managed to solve it. I used Handler and Thread with a progressBar.
I put here the code, i hope help you.
