As my app's tendrils root further into the mobile OSs, I've found one very
troubling issue. I have an alarm manager and a service to handle the pending
intent. The service talks to Qt through JNI. This works for as long as my Qt
Activity exists. However if the activity is closed (user task kills it) the
service keeps running (as it should) but then the native JNI functions stop
working.
I'm thinking we should be able to associate the native functions with the
application, or a default service so that the native functions always exist?
Is there a way to prevent this? Logs below. This does work until the activity
is killed.
