Android获取所有小区信息

我正在研究3G和4G网络监控。我尝试显示4G的RSRP，RSSI和SINR等小区信息（RSCP，RSSI，3G的EcNo）。我发现方法getAllCellInfo（）可以为我做的工作，因为它包含我需要的所有东西，但它的值始终为null。 以下是3G小区信息的代码：

 protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

        if (tm.getNetworkType() == 3 || tm.getNetworkType() == 8 || tm.getNetworkType() == 9 || tm.getNetworkType() == 10
        || tm.getNetworkType() == 15) {
            // Network Type is 3G
            setContentView(R.layout.report_val_layout_3g);

            sigLevTextView = (TextView) findViewById(R.id.sigLevTextView);
            rssiTextView = (TextView) findViewById(R.id.rssiTextView);
            sigQualTextView = (TextView) findViewById(R.id.sigQualTextView);
            cellIDTextView = (TextView) findViewById(R.id.cellIDTextView);

            signalStrengthListener = new SignalStrengthListener();

            ((TelephonyManager)getSystemService(TELEPHONY_SERVICE)).listen(signalStrengthListener, SignalStrengthListener.LISTEN_SIGNAL_STRENGTHS);
            tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        }

    try {
                    cellInfoList = tm.getAllCellInfo();
                } catch (Exception e) {
                    Log.d("SignalStrength", "+++++++++++++++++++++++++++++++++++++++++ null array spot 1: " + e);
                }

try {
            cellInfoList = tm.getAllCellInfo();
            for (CellInfo cellInfo : cellInfoList) {
                if (cellInfo instanceof CellInfoWcdma){
                    sigLev = ((CellInfoWcdma) cellInfo).getCellSignalStrength().getDbm();
                    asu = ((CellInfoWcdma) cellInfo).getCellSignalStrength().getAsuLevel();
                    rssi = -113 + 2 * asu;
                    sigQual = 10 * Math.log10(sigLev / rssi); //EcNo
                    cellID = ((CellInfoWcdma) cellInfo).getCellIdentity().getCid();

                }
            }
        } catch  (Exception e) {
            Log.d("SignalStrength", "+++++++++++++++++++++++++++++++ null array spot 2: " + e);
        }

 @Override
    protected void onPause() {
        super.onPause();

        try{
            if(signalStrengthListener != null){tm.listen(signalStrengthListener, SignalStrengthListener.LISTEN_NONE);}
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        try{
            if(signalStrengthListener != null){tm.listen(signalStrengthListener, SignalStrengthListener.LISTEN_NONE);}
        }catch(Exception e){
            e.printStackTrace();
        }
    }

    public class SignalStrengthListener extends PhoneStateListener{

        @Override
        public void onSignalStrengthsChanged(SignalStrength signalStrength) {

            ((TelephonyManager)getSystemService(TELEPHONY_SERVICE)).listen(signalStrengthListener, SignalStrengthListener.LISTEN_SIGNAL_STRENGTHS);
            tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);


            try {
                cellInfoList = tm.getAllCellInfo();
               for (CellInfo cellInfo : cellInfoList) {
                   if (cellInfo instanceof CellInfoWcdma) {
                       sigLev = ((CellInfoWcdma)cellInfo).getCellSignalStrength().getDbm();
                       asu = ((CellInfoWcdma)cellInfo).getCellSignalStrength().getAsuLevel();
                       rssi = -113 + 2 * asu;
                       sigQual = 10 * Math.log10(sigLev / rssi);
                       cellID = ((CellInfoWcdma)cellInfo).getCellIdentity().getCid();
                   }
               }

        }catch  (Exception e) {
            Log.d("SignalStrength", "+++++++++++++++++++++++++++++++ null array spot 3: " + e);
        }

            sigLevTextView.setText(String.valueOf(sigLev));
            rssiTextView.setText(String.valueOf(rssi));
            sigQualTextView.setText(String.valueOf(sigQual));
            cellIDTextView.setText(String.valueOf(cellID));

            super.onSignalStrengthsChanged(signalStrength);
        }
    }

在清单文件中，我使用了3个权限：ACCESS_COARSE_LOCATION，ACCESS_NETWORK_STATE和READ_PHONE_STATE。 似乎代码在异常n°3中停止，这是日志：
