Java how to hide status bar in android studio kotlin

To hide the status bar in an Android app using Kotlin in Android Studio, you can use the following code:

// hide the status bar
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN

This code can be placed in the onCreate method of your Activity class, or in any other method where you want to hide the status bar.

If you want to hide the status bar only temporarily and show it again later, you can use the following code to hide it:

// hide the status bar
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN

And use the following code to show it again:

// show the status bar
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_VISIBLE

Note that this will only work on devices running Android 4.1 (API level 16) or higher.
