M Mike1970 Well-Known Member Licensed User Longtime User Oct 18, 2019 #1 Hi everyone, i'm coding an app for quite a whille (before the update), and i quitted beacuse the SO kill my foreground process while the app is in background, so after an random period of time it stop working. I wish to know if there is a way with the new update to prevent the OS to kill my process/service (I already tried the Erel's example of gps tracking, my phone kill even that after a while. My phone: Meizu m5c) Last edited: Oct 18, 2019

For example in settings>Apps>Now i can see what apps/services are running and the time elapsed from opening. My app there isn't because it was killed after 2/3 hours, but the other apps are still running after 6+ hours at this point Upvote 0

M Mike1970 Well-Known Member Licensed User Longtime User Oct 18, 2019 #8 it is VERY VERY ANNOYING, i can't do what i want to do, i have to verify if a person is in a determinate place until the users decide to close the app himself. But if the OS kill the app when it want, so i can't develop my app correctly.... Last edited: Oct 18, 2019 Upvote 0

You can have your service running in the background but you need to create a foreground service and a notification will show the whole time until you or the user decides to kill the device. Do a search for foreground services. Walter Upvote 0

D dgoss Member Licensed User Longtime User Oct 19, 2019 #12 This works for me, i run an app that uses Gps for up to 15Hrs a day 6 days a week with no problems.

The only difference with yours is that I set Code: notification.IMPORTANCE_LOW instead of Code: notification.IMPORTANCE_HIGH And that i restart the service every 10 minutes instead of 30 Last edited: Oct 19, 2019 Upvote 0

Yeah, i discovered that thing yesterday, but my phone killed also that one, but now i realized that maybe i have to start the service as foreground service right? Because the original code doesn't.

Now i'm trying with an interval of 30 minutes just in case (but the purpose of the app it's count how many time a person stay in a determinate place, if the precision is +-30min it is very imprecise) Upvote 0
