Question

When I start regular endless Java thread from Activity I see this thread still running even
when the activity destroyed pressing back button or calling by Finish()
from the activity.
The thread stops when I force destroy the application.
My question is if Android destroys this thread in some condition or it will run forever?
Thanks 🙂

Answer 1

Thread will terminate if :

1. Parent process is closed, killed. (Android OS can do this any time, user can do it in settings)
2. Is explicitly Interrupted, and interrupt is not handled. (during blocking IO operations)
3. Run methods returns. ( good coding 🙂 )
4. Some un-handled exception surfaces. ( possible )
