Great you are on the right post! Previously I was working on the Java language for developing an android application. I thought to move with new technology in android development. Then I move completely with Kotlin Language for android application development. But somewhere I have found that some keys and syntax has been changed. One of then instanceof. I was trying to find the solution with the instanceof keyword, but in Kotlin nothing is like that to check instance of. So there is a small question in front of every Android developer. which is

How to check the instanceof anything in android Kotlin

Finally I have fond the solution of this question and I am sharing with you people.

fun checkInstanceOFActivityInFragment() {
        if (activity is MainActivity) {
            //Main Activity
        } else if (activity is OTPActivity) {
            //OTP Activity

fun checkInstanceOfFragment(){
        val f = supportFragmentManager.findFragmentById(
        if (f is FragmentOne) {
            //Fragment One
        } else if (f is FragmentTwo) {
            //Fragment Two
