If you are a kotlin developer, then you can use the code below to check which mode your app is in..

val mode = context?.resources?.configuration?.uiMode? and Configuration.UI_MODE_NIGHT_MASK
when (mode) {
    Configuration.UI_MODE_NIGHT_YES -> {}
    Configuration.UI_MODE_NIGHT_NO -> {}
    else -> {} //covers Configuration.UI_MODE_NIGHT_UNDEFINED
}
