Android读取SIM卡ICCID

方法一，使用TelephonyManager的getSimSerialNumber()获取

TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(TELEPHONY_SERVICE);
String iccid = telephonyManager.getSimSerialNumber()

需要添加权限：<uses-permission android:name="android.permission.READ_PHONE_STATE" />

方法二，通过发AT命令读取SIM卡ICCID(可以解决读取某些SIM卡ICCID长度不对的问题)

     new Thread(new Runnable() {@Overridepublic void run() {String com = "/dev/ttyUSB2";String cmd = "at+qccid\r\n";if(adbcommand("chmod 0777 "+com) && sendAtCmd(com,cmd)){iccidtv.setText("ICCID:"+recAtresult(com));}iccidtv.setText("ICCID:"+recAtresult(com));//iccidtv.setText("ICCID:"+getSimSerialNumber(getApplicationContext()));}}).start();public boolean adbcommand(String command) {Process process = null;DataOutputStream os = null;//String excresult = "";try {process = Runtime.getRuntime().exec("su");os = new DataOutputStream(process.getOutputStream());os.writeBytes(command + "\n");os.writeBytes("exit\n");os.flush();if (process.waitFor() != 0) {// System.err.println("exit value = " + process.exitValue());}BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));StringBuffer stringBuffer = new StringBuffer();String line = null;while ((line = in.readLine()) != null) {stringBuffer.append(line + " ");}//excresult = stringBuffer.toString();// System.out.println(excresult);return true;} catch (Exception e) {e.printStackTrace();return false;}//return excresult;}public static boolean sendAtCmd(String fileName, String atcmd) {boolean atResult = true;// at指令的返回结果Log.i(TAG, "fileName = " + fileName + ", atcmd = " + atcmd);try {BufferedWriter atWriter = new BufferedWriter(new FileWriter(fileName));atWriter.write(atcmd, 0, atcmd.getBytes().length);atWriter.flush();atWriter.close();atWriter = null;// 以上是往fileName该通道写入AT指令} catch (FileNotFoundException e2) {Log.e(TAG, "FileNotFoundException :" + fileName);atResult = false;} catch (IOException e) {atResult = false;e.printStackTrace();}return atResult;}public String recAtresult(String fileName) {int read_len = 0;// 下面来读取该通道里的AT指令返回结果BufferedReader atReader;String readAtString = null;char[] cReaderBuffer = new char[255];try {atReader = new BufferedReader(new FileReader(fileName));try {atReader.close();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}atReader = null;try {read_len = atReader.read(cReaderBuffer, 0,cReaderBuffer.length - 1);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}} catch (FileNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();}Log.i(TAG, "read_len = " + read_len);if (read_len > 0) {if (null == readAtString) {readAtString = String.copyValueOf(cReaderBuffer, 0, read_len);} else {readAtString = readAtString+ String.copyValueOf(cReaderBuffer, 0, read_len);}Log.i(TAG, "readAtString = " + readAtString);}return readAtString;}
