in every change the notofication sent to app how ?? ( if mobile closed the notification sent to it too )
how often do you plan to connect to that api to check for new values? for example every hour?
you could use my alarmmanager extension together with itoo, which allows you to call your api at a specific time regularly in the background, get the return value in the background and decide, if a notification should be displayed

my policy is not calling api --- i wanna call a label changes only if its value changed send notification --- and when the value changed first send notification and after that stores that value as an old value and if this second value changed send notification --- and set the last one as and old value
So how can you find out, if that value changed without calling that API?
Do you like to reveal, which API you are talking about?
