how android device information without open app. after application upgrade google play store app display open button want user device push notification without open application.
push notification or other background services not implemented in last build.
divide situation 2 cases:
- new app:
there no way start app without user pressing it, android system prevent it. best thing put bootreceiver , when user restarts device register , stuf..
- upgraded app:
push should work same regiid, send silent push device "wake" him , thing without posting notification user.
as situation: there no other way create new build , add bootreceiver because dont have regid push yet. luck
