Runnable RemoveCallbacks, похоже, не работает, поэтому новый Runnable не запускается ⇐ Android

[Anonymous]

Я пытаюсь создать простой трекер экрана, который также отслеживает ваш экран, когда он выключен. По какой-то причине кажется, что screenTimeRunnable не хочет останавливаться, и поэтому offScreenTimeRunnable никогда не получает возможности обновить offScreenTime. Я точно не знаю, в этом ли дело.

interface ScreenTimeUpdateListener {
fun onScreenTimeUpdated(screenTime: Long, offScreenTime: Long)
}
class ScreenTimeReceiver : BroadcastReceiver() {
var listener: ScreenTimeUpdateListener? = null

private var screenOn = true
private var screenTime = 0L
private var offScreenTime = 0L
private val handler = Handler(Looper.getMainLooper())
private val updateInterval = 1000L

private val screenTimeRunnable = object : Runnable {
override fun run() {
if (screenOn) {
screenTime += updateInterval
listener?.onScreenTimeUpdated(screenTime, offScreenTime)
}
handler.postDelayed(this, updateInterval)
}
}

private val offScreenTimeRunnable = object : Runnable {
override fun run() {
if (!screenOn) {
offScreenTime += updateInterval
listener?.onScreenTimeUpdated(screenTime, offScreenTime)
}
handler.postDelayed(this, updateInterval)
}
}

override fun onReceive(context: Context, intent: Intent) {
when (intent.action) {
Intent.ACTION_SCREEN_ON -> {
Log.d("ScreenTimeReceiver", "Screen ON detected")
screenOn = true
Log.d("ScreenTimeReceiver", "screenOn set to: $screenOn")
resetHandler()
}
Intent.ACTION_SCREEN_OFF ->  {
Log.d("ScreenTimeReceiver", "Screen OFF detected")
screenOn = false
Log.d("ScreenTimeReceiver", "screenOn set to: $screenOn")
resetHandler()
}
}
}

private fun resetHandler() {
handler.removeCallbacks(screenTimeRunnable)
handler.removeCallbacks(offScreenTimeRunnable)

if (screenOn) {
Log.d("ScreenTimeReceiver", "Posting screenTimeRunnable")
handler.post(screenTimeRunnable)
} else {
Log.d("ScreenTimeReceiver", "Posting offScreenTimeRunnable")
handler.post(offScreenTimeRunnable)
}
}

fun startTracking() {
resetHandler()
}

fun stopTracking() {
handler.removeCallbacksAndMessages(null)
}
}

this.screenTime = screenTime
this.offScreenTime = offScreenTime
points = (this.offScreenTime / 1000).toInt()

Я уже пробовал использовать handler.removeCallbacksAndMessages(null) как отдельно, так и с тем, что у меня уже есть.
Я ожидаю screenTime, чтобы остановить приращение, когда offScreenTime выключен, и offScreenTime, чтобы начать приращение.
