Answer 1

There is getAllCellInfo() method in TelephonyManager added in API 17 that could be good solution. Example of use:

TelephonyManager telephonyManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
// for example value of first element
CellInfoGsm cellInfoGsm = (CellInfoGsm)telephonyManager.getAllCellInfo().get(0);
CellSignalStrengthGsm cellSignalStrengthGsm = cellInfoGsm.getCellSignalStrength();
cellSignalStrengthGsm.getDbm();
