问题 I am retrieving cell information data ( CellInfo ) from TelephonyManager For each cell info object, I am querying for mcc (Mobile Country Code) and mnc (Mobile Network Code) via eachCellInfo.cellIdentity.mcc eachCellInfo.cellIdentity.mnc Where eachCellInfo is an object of CellInfo The function is deprecated as per the doc: /** * @return 2 or 3-digit Mobile Network Code, 0..999, Integer.MAX_VALUE if unknown * @deprecated Use {@link #getMncString} instead. */ @Deprecated public int getMnc() {

问题 Does anyone know if the cell indexes on the list returned from TelephonyManager.getAllCellInfo() are related to SIM slot numbers? I'm using Android API 24... After experimenting a bit, it seems that running the method updateCellInfo - described below - always returns a list where it's first index corresponds to device's last SIM slot, and it's last index corresponds to device's first SIM slot. Can anybody confirm this? Is this correlation plausible? private ArrayList<CellInfo> updateCellInfo

But I can't figure out how to use CallScreeningService to get incoming call phone number. Anyone can help me? 回答1: As @Saurabh said, the new way to screen calls is
