Now that you’ve set up the resizability support, you can move onto adding more checks and lifecycle handling to your app.

private var wasInEditMode: Boolean = false
// initUi()
if (!isChecked) {
  ...
  } else {
  wasInEditMode = true
}
  override fun onMultiWindowModeChanged(isInMultiWindowMode: Boolean, newConfig: Configuration?) {
    super.onMultiWindowModeChanged(isInMultiWindowMode, newConfig)

  }
    if (isInMultiWindowMode) {
      binding.editSwitch.isChecked = false
    } else if (!isInMultiWindowMode && wasInEditMode) {
      binding.editSwitch.isChecked = true

      wasInEditMode = false
    }
