telephonyManager.getAllCellInfo() 和 subscriptionManager.getActiveSubscriptionInfoList() 都返回不同的 mnc（移动网络代码）

Question

我正在尝试获取双 sims 的信号强度，它在大多数手机上都可以正常工作，但对于某些手机（相同的 android 版本 [11] 但地理位置不同）我们从subscriptionManager.getActiveSubscriptionInfoList() 收到的 MNC 代码和telephonyManager.getAllCellInfo() 不匹配。

我正在通过以下代码获取 getAllCellInfo

 ArrayList<CellInfo> allCellInfo = new ArrayList<>(telephonyManager.getAllCellInfo());

allCellInfo 值如下

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() 如下所示获取

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
    subManager = (SubscriptionManager)context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
    activeSubscriptionInfoList = subManager.getActiveSubscriptionInfoList();
}

activeSubscriptionInfoList 值如下

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}

从上面的例子你可以看到我的设备中有两张 sim 卡由 activeSubcriptionInfoList 获取，with MNC 856 for simSlot 0 和 MNC 67 for simSlot 1。

但是你可以清楚的看到allCellInfo没有MNC 856和MNC 67，而是有MNC 866和MNC 753

如何解决这个问题？如何将 CellInfo 列表映射到具有不同 MNC 值的 simSlot 0 和 SimSlot 1 ？

提前致谢..

Answer 1

我通过使用cellinfo的数组索引将其映射到simSlot 0/1来解决它，

创建了仅存储已注册 Cellinfo 的新列表

ArrayList<CellInfo> registeredCellinfo = new ArrayList<>();
  for (CellInfo rcinfo : allCellInfo) {
    if (rcinfo.isRegistered()) {
       registeredCellinfo.add(rcinfo);
    }
 }

然后获取simSlot 0 / simSlot 1 CellInfomation im返回指定simSlot处的registredCellInfo元素，（registeredCellInfo元素是有序的，simSlot 0信息会在索引0中）

 return registeredCellinfo.get(slotIndex);
