thanks in advance anand neema

gcm allows send notification 1000 device @ time, suggest refactoring method sendnotificationandroid accept array of gcm registration ids instead.

for example, first go through database rows , collect reg ids , append them array. once array size reaches 1000 (or no more reg ids add), pass new sendnotificationandroid method build notification payload this:

{   "registration_ids" : ["regid1", "regid2", "regid3", ....., "regid1000"],   "data" : {     ...   }, } 

so, 80k users, need 80 loops send notifications, , alma mundo suggested, better use curl_multi_exec send requests gcm server.
