Как получить силу сигнала Dual sim с помощью kotlin

Question

Используя прослушиватель состояния телефона, я получаю уровень сигнала сима по умолчанию, как узнать уровень сигнала второго сима. Пожалуйста, помогите мне найти эту проблему

, а также я использовал Telemetry manager, но я не получаю второй уровень сигнала сима

val phoneStateListener: PhoneStateListener = object : PhoneStateListener() {
    override fun onServiceStateChanged(serviceState: ServiceState) {
        Timber.d("Current cell state : ${serviceState.state}")
        }

    override fun onSignalStrengthsChanged(signalStrength: SignalStrength) 
        {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            Timber.d("Current cell signal: ${signalStrength.level}")
               } else {
      Timber.d("Current cell signal:${signalStrength.gsmSignalStrength}")
        }
    }
}


telephonyManager = getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_SERVICE_STATE or PhoneStateListener.LISTEN_SIGNAL_STRENGTHS)

Я получил решение выше моего вопроса

        fun getRegisteredCellInfo(cellInfos: MutableList<CellInfo>): ArrayList<CellInfo> {
    val registeredCellInfos = ArrayList<CellInfo>()
    if (cellInfos.isNotEmpty()) {
        for (i in cellInfos.indices) {
            if (cellInfos[i].isRegistered) {
                registeredCellInfos.add(cellInfos[i])
            }
        }
    }
    return registeredCellInfos
}
