Google common api

[android_dev]

I can't use the android 10 API on the galaxy 10s 5G and the latest beta version. 

https://developer.android.com/reference/android/telephony/CellInfoNr

I am using the api in our application like below, but I never get the Cellinfonr even though the device connected with 5g network. 

List allCellInfo = telephonyManager.getAllCellInfo(); boolean hasSecondaryNrCell = false;

 for (CellInfo cellInfo : allCellInfo) {   

  if (cellInfo instanceof CellInfoNr &&     cellInfo.getCellConnectionStatus() ==  CellInfo.CONNECTION_SECONDARY_SERVING) 

{         

         hasSecondaryNrCell = true;         

         break;   

  } }

These all of implementations are based on Google android 10 public api and are recommended by Google. Please add the feature according to the common specification of the android 10.
