Andorid开发获取IMEI号，获取ICCID，获取IP

有时候我们为了获取到一些手机的信息作为唯一的标记，或者开发需要。

我们如何拿IMEI号，如何拿到ICCID，IP地址呢？

IMEI号

国际移动设备识别码（International Mobile Equipment Identity，IMEI），即通常所说的手机序列号、手机“串号”，用于在移动电话网络中识别每一部独立的手机等移动通信设备，相当于移动电话的身份证。

权限：

    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

获取代码：

   public String GetIMEI() {
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (tm == null) return null;
        if (ActivityCompat.checkSelfPermission(context, 
                Manifest.permission.READ_PHONE_STATE) 
                != PackageManager.PERMISSION_GRANTED) {
            return "";
        }
        return tm.getDeviceId();
    }

ICCID

ICCID：Integrate circuit card identity 集成电路卡识别码即SIM卡卡号，相当于手机号码的身份证。 ICCID为IC卡的唯一识别号码，共有20位字符组成，其编码格式为：XXXXXX 0MFSS YYGXX XXXX。

Requires Permission: READ_PRIVILEGED_PHONE_STATE

Permission is only granted to system apps

 <uses-permission android:name="android.permission.READ_PRIVILEGED_PHONE_STATE" />

获取代码：

   private String getICCID() {
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        if (tm == null) return null;
        String simSerialNumber = tm.getSimSerialNumber();
        SobLog.d(TAG, "simSerialNumber == > " + simSerialNumber);
        return simSerialNumber;
    }

如查没有sim卡的话，就获取不到了

IP地址

    private String getIp() {
        String ip = null;
        ConnectivityManager conMann = (ConnectivityManager)
                requireContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo mobileNetworkInfo = conMann.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
        NetworkInfo wifiNetworkInfo = conMann.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

        if (mobileNetworkInfo.isConnected()) {
            ip = getLocalIpAddress();
            System.out.println("IP：" + ip);
        } else if (wifiNetworkInfo.isConnected()) {
            WifiManager wifiManager = (WifiManager) SettingApp.getInstance().getApplicationContext()
                    .getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            int ipAddress = wifiInfo.getIpAddress();
            ip = intToIp(ipAddress);
            System.out.println("WI-FI IP：" + ip);
        }
        IcLog.d(TAG, "ip ==> " + ip);
        return ip;
    }

 public String intToIp(int ipInt) {
        StringBuilder sb = new StringBuilder();
        sb.append(ipInt & 0xFF).append(".");
        sb.append((ipInt >> 8) & 0xFF).append(".");
        sb.append((ipInt >> 16) & 0xFF).append(".");
        sb.append((ipInt >> 24) & 0xFF);
        return sb.toString();
    }

    public String getLocalIpAddress() {
        try {
            String ipv4 = null;
            ArrayList<NetworkInterface> list = Collections.list(NetworkInterface.getNetworkInterfaces());
            for (NetworkInterface ni : list) {
                ArrayList<InetAddress> addresses = Collections.list(ni.getInetAddresses());
                for (InetAddress address : addresses) {
                    if (!address.isLoopbackAddress() && address instanceof Inet4Address) {
                        return ipv4;
                    }
                }

            }

        } catch (SocketException ex) {
            Log.e("ip get error", ex.toString());
        }
        return null;
    }
