Get cols/rows count (Kotlin):

val options = appWidgetManager.getAppWidgetOptions(appWidgetId)
val minHeight = options.getInt(AppWidgetManager.OPTION_APPWIDGET_MIN_HEIGHT)
val maxHeight = options.getInt(AppWidgetManager.OPTION_APPWIDGET_MAX_HEIGHT)

val oneCellHeight = ViewExtensions.convertDpToPx(40f * 1, context).toInt() - (30 * 1)
val twoCellHeight = ViewExtensions.convertDpToPx(40f * 2, context).toInt() - (30 * 2)
val threeCellHeight = ViewExtensions.convertDpToPx(40f * 3, context).toInt() - (30 * 3)
val fourCellHeight = ViewExtensions.convertDpToPx(40f * 4, context).toInt() - (30 * 4)

when {
    oneCellHeight in (minHeight..maxHeight) -> {
        // 1 cell
    }
    twoCellHeight in (minHeight..maxHeight) -> {
        // 2 cells
    }
    threeCellHeight in (minHeight..maxHeight) -> {
        // 3 cells
    }
    fourCellHeight in (minHeight..maxHeight) -> {
        // 4 cells
    }
    else -> {
        // More
    }
}

class ViewExtensions {
    companion object {
        fun convertDpToPx(sp: Float, context: Context): Float {
            return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, sp, context.resources.displayMetrics)
        }
    }
}

Based on, that 1 cell = 40dp
