PS : before resend we have to let our doing background sleep(HOW?) for abit.

Threading rule for AsyncTask:

Only once execution can be performed, any other attempt (to resume) will throw exception. (see docs)

There you can't sleep() in AsyncTask

For that purpose you can create BroadcastReciever that will listen for connectivity changes.
