Android Programming: Close entire App

If you want to work with finish(), you have to call finish() for each activity individually to close all.

To close all activities at once, you can use the following line since API 16:

this.finishAffinity();

With this, you are closing the current activity as well as all activities below in the same task having the same affinity.

By the way, the android developers have not necessarily intended that someone is about to exit an app via code. Instead, this should handle and manage the system.
