batteryInfoReceiver in Kotlin

val batteryInfoReceiver = object : BroadcastReceiver() {
    override fun onReceive(ctxt: Context, intent: Intent) {
        val batteryLevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0)
        val scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1)

        val batteryLevelScaled = batteryLevel / scale.toFloat()

        batteryLevelArray.add(Integer.valueOf(batteryLevel))
        batteryLevelScaledArray.add(java.lang.Float.valueOf(batteryLevelScaled))
        batteryScale = scale
    }
