invalidateSessionForAppLostFocus not working when screen is closed - Android 13 about local_session_timeout

[SankethBK]

Hi, I think the issue is because when you re-open the app inactive state is emitted which overwrites the previous value of _appLostFocusTimestamp. I have raised a fix, can you checkout to this branch and try once. If it works I'll merge the PR and create a new release

[SankethBK]

Great! I'll create a new release with this fix

I solve mine by adding a package called wakelock_plus, In this case we know that the app is still in foreground even the though it's on screen.

e.g.

When app is inactive call the WakeLockPlus.enable();
When app is resumed call the WakeLockPlus.disable()

I hope this finds you helpful.

Hi @guperini , Android kills background processes for power saving ref.

Thanks for the input @Erchil66 , I'll go through the package and see if same can be used here

Hi, i've fixed this issue in latest release 3.0.0. I have removed the timer completely which has risk of getting terminated from OS, instead storing the timestamp when app is pushed to the background and calculating the time difference when app regains focus.

Hi, In my case when app in minimize (background -> foreground) invalidateSessionForAppLostFocus is work in first time but next time when minimize again it not work. I am not sure is cause from time stamp in status inactive set new time. thank you.

minimize (foreground -> background)

flutter: state AppLifecycleState.inactive
flutter: state AppLifecycleState.hidden
flutter: state AppLifecycleState.paused

open app again (background -> foreground)

flutter: state AppLifecycleState.hidden
flutter: state AppLifecycleState.inactive
flutter: state AppLifecycleState.resumed

Hi @klaokamol I'll check this

[SankethBK]

@klaokamol Its working fine for me, can you check if the same issue is occurring in the example app? You can disable invalidateSessionForUserInactivity by passing null so that it won't interrupt.

Thank you for reply, I'm testing by use same code like exmaple: Sample Usage and rollback to old version is work fine.
my invalidateSessionForUserInactivity duration set to 1 second

test step:

1. run app first minimize app and open app again
   (invalidateSessionForAppLostFocus is work in first time and timeoutEvent == SessionTimeoutState.appFocusTimeout)

2. minimize app (foreground -> background)

flutter: state AppLifecycleState.inactive -> lib stamp time 00:01:30.00
flutter: state AppLifecycleState.hidden
flutter: state AppLifecycleState.paused

3. open app again (background -> foreground)

flutter: state AppLifecycleState.hidden
flutter: state AppLifecycleState.inactive -> lib stamp time 00:01:31.00
flutter: state AppLifecycleState.resumed -> check dif time ( 00:01:31.00 and 00:01:30.02) < 1s

difference time in SessionTimeoutManager function didChangeAppLifecycleState is always false because it's double stamp time. and sessionConfig.stream.listen((SessionTimeoutState timeoutEvent) not call back.

@SankethBK I tested it and it worked. Thanks for your help. 🙇
