Android App Exit Button

Question

I\'m not sure whether I need to add an exit button to my app. Is there any point to doing this? And if on exiting one activity or service is not .finish() or closed properly

Answer 1

No, you don't. Read up on the activity lifecycle at developer.android.com

On older versions of android you had to be careful not to accidentally leave a background service running and holding resources but that's been reworked.
