How to Kill Your Application
If your want to kill your application, there are three ways AFAIK:
>> Method #1
>> Method #2
>> Method #3
finish(); // one provided method of 'Activity' class
There’s an old usual method is to use `ActivityManager.restartPackage()`; however, it’s already deprecated from API Level 3, suggesting not to use it anymore.
If you know any other ways, feel free to share!
