How to quit android application programmatically

Question

I Found some codes for quit an Android application programatically. By calling any one of the following code in onDestroy() will it quit application entirely?

Answer 1

Similar to @MobileMateo, but in Kotlin

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
    this.finishAffinity()
} else{
    this.finish()
    System.exit(0)
}
