hi

i would like to start a Service that will kill my app after x minutes.
i am using ActivityManager for that but nothing happens.

i have added the needed permission to manifest and i am also checking that the activity is running before i try to kill it but nothing happens.

i am using android 6+.

i have also read here in some threads that others have the same issue.
is it at all possible to kill an app from a service? and also if it is the app that started that service?

i found this: http://stackoverflow.com/questions/9563404/kill-another-process-application-programmatically

Is the service part of your app? Call StopService(Me) and ExitApplication. It will kill the process.

i tried it but it didnot worked

i called Exitapplication and then StopService("")

it says in description to use an empty string if i want to close the service itself.

EDIT: after doing it i still see the app running in background. and also when i return to the app only activity_resume is fired because i exit the app via Homebutton so that means the app was not closed from that service, right?

oh, i understand. but this is something that i dont really want.

the thing is that if the app was closed from the homebutton than it will run in background and because i have some CLV with images in it, it usage something about 100MB ram.

the problem is if you have any CLEANxxx (RegClean,..) App you start get warning after x minute about an app that consume a lot RAM in background so my client ask me to kill the process after 10 minute so if a user has such a CLEAN app installed he wont get warned.

and if the app will restart then this is something i dont really want.

i could clean the CLV on Activity_Pause but when the user return it will take again about 3 sec to rebuild all CLV's so i would like to keep them running for few minutes because it happens that the user return after 1-2 min and i would like to have a quick start. but after 10 minutes the app should be killed like i would call ExitApplication from it.

is something like this possible?

thank you

I asked for a way to know if some library starts an own service, because if it is so you cannot kill your app without stopping this service, I think.

However, I would try (supposing to have only the Starter service):

' Activity - somewhere
B4X: 
CallSubDelayed(Starter, "Kill")
Activity.Finish


' Starter service
B4X: 
Sub Kill
    StopService(Me)
End Sub

Sub Service_Destroy
    ExitApplication
End Sub


All other Activities and Services should be already Finished / Stopped, of course.

I don't understand completly your post #5 but I think it is wrong to fill a CLV with 100Mb of data; you should implement a kind of pagination

i am not filling the CLV with 100mb it is just a simple list with 60 items that has 1 image view and few labels.
the result is that the app consume 100mb of ram. it is not only the CLV but i believe the CLV is not a small part of it.

Yes. It is not recommended but it is possible. Apps should let the OS decide when to kill processes.

1. Add a timer to the starter service.
2. Enable it in Activity_Pause of the activity. If there are multiple activities then you will need to do a bit more work.
3. Disable it in Activity_Resume.
4. Stop the service in the tick event and kill the process with ExitApplication.
