Signal Strength Android Dual SIM

I am trying to access some functionality on my dual SIM Android phone (LKD brand). I managed to get the functions for TelephonyManager and ITelephony via java reflection and got them working. However, I want to get the signal strength for both sim cards and I don't see a way to do this through reflection. I can get the first sim card in slot 1 using PhoneStateListener with onSignalStrengthsChanged () function.

Does anyone have any tips? The functions I got from reflection:

Thanks for the answer! I haven't tried your solution, but I found my own solution that worked.

Another constructor can be used for TelephonyManager where you can go to the SIM slot you want to control:



    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 this particular version of TelephonyManager, instead of

TelephonyManager.listen (phoneStateListener, state)

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



TelephonyManager.listenGemini (phoneStateListener1, state, 0)

for the first SIM card and

TelephonyManager.listenGemini (phoneStateListener2, state, 1)

for the second SIM-card,

where the third parameter for listenGemini

is the SIM card number.
