Don t ever put an Exit button on an Android app  Let the OS decide when to kill your Activity  Learn about the Android Activity lifecycle and implement any necessary callbacks

You cannot exit your application   Using android finish   won t exit the application  it just kills the activity   It s used when we don t want to see the previous activity on back button click   The application automatically exits when you switch off the device   The Android architecture does not support exiting the app   If you want  you can forcefully exit the app  but that s not considered good practice
