Android Question Background Task and Intent

[Emme Developer]

Hi all!
I want to make an application that do some things when you go at specific place or you connect to a wifi.
I studied intent and service, a i think the best way to achieve this is to use a sticky service.
For wifi, i can use intent to start some things when i get a wifi change connection, but i don't understand how to do this. I tried using broadcast receiver, but some answer on forum tell to use phoneEvents, but i don't find nothing related to phone Events

For gps, i think the best way is use a sticky service that every x minutes, get the position and do some stuff.
How about android O and sticky service? Is there another idea?
Thanks all

Not really, especially not on newer versions of Android. Sticky services will be killed.

It will work on new devices as long as the targetSdkVersion <= 23.

You can use StartServiceAtExactWhileIdle to start the process every 30 minutes and check the last known location with FusedLocationProvider.

Hi, many thanks for the advice. Is there not a way to get in background position in a time less 30 minutes? I need a runtime event, that check position every 30 seconds

The OS will kill your app if you try to start it every 30 seconds. You can create a foreground service and keep running in the background.

A foreground service means that when an user kill the app, service will be killed?

No.
