问题:

I have been trying to get access to some features on my android dual sim phone (the brand is LKD). I have managed to get the functions for TelephonyManager and ITelephony through java reflection, and got them to run. However i want to get the signal strength for both of the sim cards and i cannot see a way to do this through the reflection. I can get the first sim card in slot 1 through having a PhoneStateListener with the function onSignalStrengthsChanged().

Does anyone have some tips for this? Functions i got from reflection:

And btw it seems both of the sim cards are active at the same time(no need for switching between sim cards) since i can call the phone using both phone numbers without switching the sim card on the phone.

Thanks!

回答1:

For this particular version of TelephonyManager, instead of using

TelephonyManager.listen (phoneStateListener, state)

which only listens on the default SIM, you may try using 2 instances of your PhoneStateListener, and call

TelephonyManager.listenGemini (phoneStateListener1, state, 0) for the 1st SIM, and

TelephonyManager.listenGemini (phoneStateListener2, state, 1) for the 2nd SIM,

where the third parameter for listenGemini is the SIM number.

Thanks for the answer headuck! I have not tried your solution, but i found my own solution which worked.

It is possible to use a different constructor for the TelephonyManager where you can pass in the sim card slot you want control over:

    MultiSimClass = Class.forName("android.telephony.MultiSimTelephonyManager");

    for (Constructor<?> constructor : MultiSimClass.getConstructors()){
         if (constructor.getParameterTypes().length == 2){
              try {
                   multiSimTelephonyManager1 = constructor.newInstance(context,0);
                   multiSimTelephonyManager2 = constructor.newInstance(context,1);
             }
         }
     }

For fetching the sim signal strength for both the sim we have to use telephony manager

telephonyManager = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager?
            val cellInfos = telephonyManager?.allCellInfo as ArrayList
            val subManager = context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE) as SubscriptionManager?

this will give the list of cell info now through we need to fetch the registered cell info

/* Function to get registered cell info
    *  @param cellinfo - all cell info for sim
    *  @return registered cell info correspond to cell info
    */
    fun getRegisteredCellInfo(cellInfos: MutableList<CellInfo>): ArrayList<CellInfo> {
        val registeredCellInfos = ArrayList<CellInfo>()
        if (cellInfos != null && cellInfos.isNotEmpty()) {
            for (i in cellInfos.indices) {
                if (cellInfos[i].isRegistered) {
                    registeredCellInfos.add(cellInfos[i])
                }
            }
        }
        return registeredCellInfos
    }

Through register cell, you will get the list of sim info which is present in your device Now through this code which I am pasted below, you will get the signal strength according to your network types whether it is gsm, CDMA and LTE. This will also require runtime permission of access phone state and coarse location so please add them accordingly and registered cell info index is the index of sim one and sim two present in the device. Sim one is the 0 index and sim two is 1 index which you have to pass.

(registeredCellInfos.get(registeredCellInfoIndex) is CellInfoWcdma) -> {
                        val cellInfoWcdma = registeredCellInfos.get(registeredCellInfoIndex) as CellInfoWcdma
                        signalStrength = "${cellInfoWcdma.cellSignalStrength.dbm}"
                    }
                    (registeredCellInfos.get(registeredCellInfoIndex) is CellInfoGsm) -> {
                        val cellInfogsm = registeredCellInfos.get(registeredCellInfoIndex) as CellInfoGsm
                        signalStrength = "${cellInfogsm.cellSignalStrength.dbm}"
                    }
                    (registeredCellInfos.get(registeredCellInfoIndex) is CellInfoLte) -> {
                        val cellInfoLte = registeredCellInfos.get(registeredCellInfoIndex) as CellInfoLte
                        signalStrength = "${cellInfoLte.cellSignalStrength.dbm}"
                    }
