hi I want to close my application and also want kill it from ram by clicking button. i am using this method, but it just minimize application and didn\'t close complete app. wha
System.exit
will exit the VM and Android will kill this process.
Activity#finish()
is usually the popular choice, but this does not need to be executed right away and also only affects this particular Activity, not the whole process.
Just FYI: killing apps manually is not a good app design in Android (except maybe some special situations). If you could explain why you want to kill your app, we can probably tell you a better solution.
