Android Question clicking notification induce app pause?

[le_toubib]

hi
i have a Main module + a service that occasionally sends notifications (using the BARX notification builder).
in the service the notification.setactivity is set to (Main)
now assuming the main module is currently shown , when the user click on the notification icon , :
1-is that normally supposed to trigger : activity_pause -->starter_service --> activity_create --> activity_resume events (in that order?)???
i.e: relaunch the app after user clicked the notification although its still running ???
2-how to prevent that ?
3-will the starter_service be relaunched also ? if not then i d have to re_initialize all views?
4- how to detect if the Main module is currently shown or not?
thanks
and offcourse sorry for the newbie qs

yes, that´s normal.

2-how to prevent that ?

You cant

3-will the starter_service be relaunched also ?

due to your post you said it IS started....

4- how to detect if the Main module is currently shown or not?

if isPaused(Main) then
  ' do something
else
  ' main ist already visible
end if

See this thread for a nice overview over the activity lifetimecycle

is it possible to trap the event of clicking on the notification , to do some action in the currently open module , instead of reloading the whole thing ?

is it possible to trap the event of clicking on the notification

You cannot trap the event as there is NO event which is raised. The Notification will start the given Activity. What you do in starting the activity or need to do depends on your needs.

You can for sure create an transparent activity which will be called to receive the notification click. But then the transparent act is called. and this activity must give the value to another activity from yor app. So in fact ANOTHER activity will be called (incl all which is defined in the activity lifetimecycles. Activity_creat, activity_resume and so on..
Learn to life with that or dont use Notifications.

Maybe you are able to give a reference to your service instead of your activity when creating the notification.
But here too, the app will be called to call the service in this case. (an active activity will be paused and resumed too)
