  • @ScottS I want to run my main activity in the background.. My main activity have a map and i created fences on the map.. when user enter into the fence circle a notification pop up into the device.. Now i want to do a button enable (when user enter) and disable (when user exit) from fence. I dont want to show user a map i just want to show directly an activity which have 3 buttons. I hope now you all can understand which i want.. – Zeeshan Arif Nov 27 '17 at 08:03

You cannot really run an Activity on background! When an activity is not on foreground it gets to onStop and then the system could terminate it, to release resources, by onDestroy method! see Activity Lifecycle

  • Nope, But my question why activity, activity is create for foreground, iyou can use service, asynctask or job for background when your task is finish get call back in Activity – Lokesh Nov 27 '17 at 08:04
  • You are asking for wrong thing, when you set notification set callback activity that you want to show – Lokesh Nov 27 '17 at 08:11
  • First mine task was to show on activity that's why i created activity now his new requirement this main activity should be invisible for user.. – Zeeshan Arif Nov 27 '17 at 08:13
