activity.finish does not close my app

You must close each activity that is running with activity.finish. If you have two activities and you are in activity two and close it, you will then be returned to the first activity.

but i am closing the main activity, do i have to close all activities before i close the main? then my app will exit?

thanx

Yes, all activities must be closed. I would close the first activity to run last.

suggest that when you change the current Activity you should use the code below:

StartActivity(secondActivity)
Activity.finish

Yes, that is correct if you want ,when you start second activity, the main activity will close.
But if i understand correctly, you wanted to close completely the app...
So you can use:

ExitApplication should not be used under normal circumstances. You should leave the OS to decide when to kill your app.

You need to define how you want or need to navigate between your activities.
Let's take some examples.
We have three activities Main, Page1, Page2 and we go back with the back button.
The navigations below work without any Activity.Finish.
1) Main > Page1 (Back) > Main > Page2 (Back) > Main (Back) > Exit
2) Main > Page1 > Page2 (Back) > Page1 (Back) > Main (Back) > Exit
In example 2) if you had an Activity.Finish in Page2 you would't go back to Page1 but directly to Main.

If you want a navigation like this:
3) Main > Page1 > Page2 (Back) > Main (Back) > Exit
Here you need an Activity.Finish in Page1

There is no general rule you must define how you want to navigate and according to this you should add Activity.Finish or not.

Best regards.
