Question

I have an activity that starts 3 threads that make a
“While(true)” loop

when i start a new activity, does those threads terminate themselves?

And another question, how do i start a new activity but i don’t want to allow
the ‘back’ button to return me to the old activity –
actually i want to dispose the first activity and create and show a new one

thank you
Ron

No, they don’t. You have to stop them before closing your activity.

how do i start a new activity but i don’t want to allow the ‘back’ button to return me to the old activity

Just call finish() from your first activity when you start the second one :

Intent intent = new Intent(...);
startActivity(intent);
finish();
