Get the size of my homescreen widget

Question

I just want to know how big my current widget is. I found tons of questions to set the minimum size, but I don\'t want to set it. Instead I want to show that informations which

Answer 1

We can't get widget size from OPTION_APPWIDGET_MAX_WIDTH and OPTION_APPWIDGET_MAX_HEIGHT it will return wrong values.

This solution based on @Zanael answer. And I add delta value because on some device cellSize can be not in minSize and maxSize range.

private fun getWidgetSize(minSize: Int, maxSize: Int, context: Context): Int {
    var delta = Int.MAX_VALUE
    var lastDeltaRecord = -1
    for (i in 1..30) {
        val cellSize = convertDpToPx(40f * i, context).toInt() - (30 * i)
        if (cellSize in minSize..maxSize) {
            return i
        }
        val deltaMin = abs(minSize - cellSize)
        val deltaMax = abs(cellSize - maxSize)
        if (delta > deltaMin) {
            delta = deltaMin
            lastDeltaRecord = i
        }
        if (delta > deltaMax) {
            delta = deltaMax
            lastDeltaRecord = i
        }
    }
    return lastDeltaRecord
}

private fun convertDpToPx(sp: Float, context: Context): Float {
    return TypedValue.applyDimension(
        TypedValue.COMPLEX_UNIT_DIP,
        sp,
        context.resources.displayMetrics
    )
}
