How to close second activity including a fragment?

Question

I have a MainActivity where I start (via button click) another second activity:

val intent = Intent(activity, SecondActivity::class.java)
startActivity(intent)

In that SecondActivity I inflate a SecondFragment.

When I:

Tap button to start SecondActivity
Automatically, in its onCreate() SecondFragment is inflated
When I want to go back to MainActivity by tapping back button, I get a white blank screen (I guess it deflates SecondFragment, but SecondActivity still running?!).
I have to press back button another second time, to actually go back to MainActivity

How can go from SecondFragment (--> SecondActivity) --> MainActivity with pressing just once?

Directly Goto MainActivity.java add this method to SecondActivity.java

@Override
public void onBackPressed() {
    finish(); 
}

This is redundant. The default implementation of `onBackPressed()` already does exactly this (call `finish()`). Overriding the method and providing this implementation is 100% redundant. It accomplishes NOTHING. – David Wasser May 21 '19 at 13:19
