Android 4: Developer options: Don't save activities?

Question

Android

In the phone settings under "Developer options" there is an option "Do not save transactions". In the description of the option, in small print, it says "Delete all operations immediately after they are completed by the user."
Can anyone explain in simple terms with examples what this means?
For some users, for some reason this option turns on and the program does not work safely as expected.

Answer 1

This means - do not keep the activity active, but kill it right away.
This option is used to check situations when, for example, the application should be closed due to lack of memory or if it has not been active for a very long time. With this option, you don't have to wait for the application to be closed by the system, by checking the box, you ask to close everything at once, so you can test all possible situations. Here, usually a lot of things immediately pop up, which is not visible in the normal mode, mainly related to saving and restoring the state of the activity.
You, as a developer, must enable this option for yourself and make sure that the program works properly.
