I'm trying to get the signal strength of dual sims it works absolutely fine on most of the phones but for some phones (same android version [11] but different geographic location) the MNC code what we receive from subscriptionManager.getActiveSubscriptionInfoList()
and telephonyManager.getAllCellInfo()
does not matches.
I'm fetching the getAllCellInfo by following code
ArrayList<CellInfo> allCellInfo = new ArrayList<>(telephonyManager.getAllCellInfo());
allCellInfo values are as follow
allCellInfo Size:6
CellInfoLte:{mRegistered=YES mTimeStamp=76968972213907ns mCellConnectionStatus=0 CellIdentityLte:{ mCi=483863 mPci=231 mTac=154 mEarfcn=38750 mBands=[] mBandwidth=2147483647 mMcc=405 mMnc=866 mAlphaLong=JIO 4G mAlphaShort=JIO 4G mAdditionalPlmns={} mCsgInfo=null} CellSignalStrengthLte: rssi=2147483647 rsrp=-100 rsrq=-13 rssnr=0 cqi=2147483647 ta=6 level=2 parametersUseForLevel=0 android.telephony.CellConfigLte :{ isEndcAvailable = false }}

subscriptionManager.getActiveSubscriptionInfoList() is fetched like bellow
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
subManager = (SubscriptionManager)context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
activeSubscriptionInfoList = subManager.getActiveSubscriptionInfoList();
}
activeSubscriptionInfoList values are as follow
activeSubscriptionInfoList Size:2
{id=2 iccId= simSlotIndex=0 carrierId=2018 displayName=Jio 4G carrierName=Jio 4G nameSource=0 iconTint=-13408298 number= dataRoaming=1 iconBitmap=android.graphics.Bitmap@58bcc24 mcc=405 mnc=856 countryIso=in isEmbedded=false nativeAccessRules=null cardString= cardId=1 isOpportunistic=false groupUUID=null isGroupDisabled=false profileClass=-1 ehplmns=null hplmns=null subscriptionType=0 groupOwner=null carrierConfigAccessRules=null areUiccApplicationsEnabled=true}
{id=1 iccId= simSlotIndex=1 carrierId=1963 displayName=Vodafone IN carrierName=Vi India | Vodafone IN nameSource=1 iconTint=-16746133 number= dataRoaming=0 iconBitmap=android.graphics.Bitmap@c91138d mcc=405 mnc=67 countryIso=in isEmbedded=false nativeAccessRules=null cardString= cardId=0 isOpportunistic=false groupUUID=null isGroupDisabled=false profileClass=-1 ehplmns=null hplmns=null subscriptionType=0 groupOwner=null carrierConfigAccessRules=null areUiccApplicationsEnabled=true}
from above example you can see that I have two sim cards in the device which is fetched by the activeSubcriptionInfoList, with MNC 856 for simSlot 0
and MNC 67 for simSlot 1
.
But you can clearly see that allCellInfo does not have MNC 856
and MNC 67
, instead it has MNC 866
and MNC 753
How to solve this issue ? how to map the CellInfo list to simSlot 0 and SimSlot 1 with different MNC values ?
Thanks in Advance..
I solved it by using the array index of cellinfo to map it to the simSlot 0/1,
created the new list of to store only the registered Cellinfo
ArrayList<CellInfo> registeredCellinfo = new ArrayList<>();
for (CellInfo rcinfo : allCellInfo) {
if (rcinfo.isRegistered()) {
registeredCellinfo.add(rcinfo);
}
}
then to get the simSlot 0 / simSlot 1 CellInfomation im returning the registredCellInfo element at the specified simSlot, (registeredCellInfo elements are ordered, simSlot 0 information will be in the index 0)
return registeredCellinfo.get(slotIndex);
