来源：互联网发布：银行家算法实验报告编辑：程序博客网时间：2024/05/29 03:53

一、使用TelephonyManager获取手机信息

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

private void getSystemPhoneMessage() {TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);// 手机串号:GSM手机的 IMEI 和 CDMA手机的 MEID.String deviceID = telephonyManager.getDeviceId();// 手机号(有些手机号无法获取，是因为运营商在SIM中没有写入手机号)String tel = telephonyManager.getLine1Number();// 获取手机SIM卡的序列号String imei = telephonyManager.getSimSerialNumber();// 获取客户id，在gsm中是imsi号String imsi = telephonyManager.getSubscriberId();// 电话方位CellLocation str = telephonyManager.getCellLocation();// 运营商名称,注意：仅当用户已在网络注册时有效,在CDMA网络中结果也许不可靠String networkoperatorName = telephonyManager.getNetworkOperatorName();// 取得和语音邮件相关的标签，即为识别符String voiceMail = telephonyManager.getVoiceMailAlphaTag();// 获取语音邮件号码：String voiceMailNumber = telephonyManager.getVoiceMailNumber();// 获取ISO国家码，相当于提供SIM卡的国家码。String simCountryIso = telephonyManager.getSimCountryIso();/** * 电话状态： 1.tm.CALL_STATE_IDLE=0 无活动 2.tm.CALL_STATE_RINGING=1 响铃 * 3.tm.CALL_STATE_OFFHOOK=2 摘机 */int callState = telephonyManager.getCallState();/** * 设备的软件版本号： 例如：the IMEI/SV(software version) for GSM phones. Return * null if the software version is not available. */String devicesoftware = telephonyManager.getDeviceSoftwareVersion();/** * 获取ISO标准的国家码，即国际长途区号。 注意：仅当用户已在网络注册后有效。 在CDMA网络中结果也许不可靠。 */String networkCountry = telephonyManager.getNetworkCountryIso();/** * MCC+MNC(mobile country code + mobile network code) 注意：仅当用户已在网络注册时有效。 * 在CDMA网络中结果也许不可靠。 */String networkoperator = telephonyManager.getNetworkOperator();/** * 当前使用的网络类型： 例如： NETWORK_TYPE_UNKNOWN 网络类型未知 0 NETWORK_TYPE_GPRS GPRS网络 * 1 NETWORK_TYPE_EDGE EDGE网络 2 NETWORK_TYPE_UMTS UMTS网络 3 * NETWORK_TYPE_HSDPA HSDPA网络 8 NETWORK_TYPE_HSUPA HSUPA网络 9 * NETWORK_TYPE_HSPA HSPA网络 10 NETWORK_TYPE_CDMA CDMA网络,IS95A 或 IS95B. 4 * NETWORK_TYPE_EVDO_0 EVDO网络, revision 0. 5 NETWORK_TYPE_EVDO_A EVDO网络, * revision A. 6 NETWORK_TYPE_1xRTT 1xRTT网络 7 */int netWorkType = telephonyManager.getNetworkType();/** * 手机类型： 例如： PHONE_TYPE_NONE 无信号 PHONE_TYPE_GSM GSM信号 PHONE_TYPE_CDMA * CDMA信号 */int phoneType = telephonyManager.getPhoneType();/** * 获取SIM卡提供的移动国家码和移动网络码.5或6位的十进制数字. SIM卡的状态必须是 * SIM_STATE_READY(使用getSimState()判断). */String simOperator = telephonyManager.getSimOperator();/** * 服务商名称： 例如：中国移动、联通 SIM卡的状态必须是 SIM_STATE_READY(使用getSimState()判断). */String simOperatorName = telephonyManager.getSimOperatorName();/** * SIM的状态信息： SIM_STATE_UNKNOWN 未知状态 0 SIM_STATE_ABSENT 没插卡 1 * SIM_STATE_PIN_REQUIRED 锁定状态，需要用户的PIN码解锁 2 SIM_STATE_PUK_REQUIRED * 锁定状态，需要用户的PUK码解锁 3 SIM_STATE_NETWORK_LOCKED 锁定状态，需要网络的PIN码解锁 4 * SIM_STATE_READY 就绪状态 5 */int simStat = telephonyManager.getSimState();/** * ICC卡是否存在 */boolean bl = telephonyManager.hasIccCard();/** * 是否漫游: (在GSM用途下) */boolean blean = telephonyManager.isNetworkRoaming();/** * 附近的电话的信息: 类型：List<NeighboringCellInfo> * 需要权限：android.Manifest.permission#ACCESS_COARSE_UPDATES */List<NeighboringCellInfo> list = telephonyManager.getNeighboringCellInfo();// List<NeighboringCellInfo>/** * 获取数据连接状态 */int dataActivty = telephonyManager.getDataActivity();}

二、android系统信息（内存、cpu、sd卡、电量、版本）获取

1、内存（ram）：

android的总内存大小信息存放在系统的/proc/meminfo文件里面，可以通过读取这个文件来获取这些信息：

public void getTotalMemory() {          String str1 = "/proc/meminfo";          String str2="";          try {              FileReader fr = new FileReader(str1);              BufferedReader localBufferedReader = new BufferedReader(fr, 8192);              while ((str2 = localBufferedReader.readLine()) != null) {                  Log.i(TAG, "---" + str2);              }          } catch (IOException e) {          }      }

运行信息如下：

05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---MemTotal:       204876 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---MemFree:          4596 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---Buffers:         16020 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---Cached:          82508 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---SwapCached:         64 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---Active:         137104 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---Inactive:        41056 kB05-30 08:05:14.807: INFO/-SystemInfo-(1519): ---SwapTotal:       65528 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---SwapFree:        65368 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---Dirty:              88 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---Writeback:           0 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---AnonPages:       79672 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---Mapped:          38296 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---Slab:             5768 kB05-30 08:05:14.817: INFO/-SystemInfo-(1519): ---SReclaimable:     1856 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---SUnreclaim:       3912 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---PageTables:       8184 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---NFS_Unstable:        0 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---Bounce:              0 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---CommitLimit:    167964 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---Committed_AS: 11771920 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---VmallocTotal:   761856 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---VmallocUsed:     83656 kB05-30 08:05:14.827: INFO/-SystemInfo-(1519): ---VmallocChunk:   674820 kB

第一行是总内存大小(即用户可以使用的ram的大小)！其他各项的介绍大家可以看这儿：
http://bg135.com/android-phones-to-get-the-total-memory-and-available-memory.html

获取当前剩余内存(ram)大小的方法：

public long getAvailMemory() {          ActivityManager am = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);          ActivityManager.MemoryInfo mi = new ActivityManager.MemoryInfo();          am.getMemoryInfo(mi);          return mi.availMem;      }

2、Rom大小

public long[] getRomMemroy() {          long[] romInfo = new long[2];          //Total rom memory          romInfo[0] = getTotalInternalMemorySize();            //Available rom memory          File path = Environment.getDataDirectory();          StatFs stat = new StatFs(path.getPath());          long blockSize = stat.getBlockSize();          long availableBlocks = stat.getAvailableBlocks();          romInfo[1] = blockSize * availableBlocks;          getVersion();          return romInfo;      }        public long getTotalInternalMemorySize() {          File path = Environment.getDataDirectory();          StatFs stat = new StatFs(path.getPath());          long blockSize = stat.getBlockSize();          long totalBlocks = stat.getBlockCount();          return totalBlocks * blockSize;      }

注意类型，不然相乘之后会有溢出。可用内部存储的大小不能通过getRootDirectory();
取得，之前网上传的很多都是用getRootDirectory()取得的，我测试之后发现取得的数值不对。要根据getDataDirectory();
取得。

三、sdCard大小

public long[] getSDCardMemory() {long[] sdCardInfo=new long[2];String state = Environment.getExternalStorageState();if (Environment.MEDIA_MOUNTED.equals(state)) {File sdcardDir = Environment.getExternalStorageDirectory();StatFs sf = new StatFs(sdcardDir.getPath());long bSize = sf.getBlockSize();long bCount = sf.getBlockCount();long availBlocks = sf.getAvailableBlocks();sdCardInfo[0] = bSize * bCount;//总大小sdCardInfo[1] = bSize * availBlocks;//可用大小}return sdCardInfo;}

注意类型，不然相乘之后会有溢出。

四、电池电量

private BroadcastReceiver batteryReceiver=new BroadcastReceiver(){          @Override          public void onReceive(Context context, Intent intent) {              int level = intent.getIntExtra("level", 0);              //  level加%就是当前电量了      }      };

然后在activity的oncreate()方法中注册

registerReceiver(batteryReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

五、CPU信息

public String[] getCpuInfo() {String str1 = "/proc/cpuinfo";String str2="";String[] cpuInfo={"",""};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) {}return cpuInfo;}

/proc/cpuinfo文件中第一行是CPU的型号，第二行是CPU的频率，可以通过读文件，读取这些数据！

六、系统的版本信息：

public String[] getVersion(){String[] version={"null","null","null","null"};String str1 = "/proc/version";String str2;String[] arrayOfString;try {FileReader localFileReader = new FileReader(str1);BufferedReader localBufferedReader = new BufferedReader(localFileReader, 8192);str2 = localBufferedReader.readLine();arrayOfString = str2.split("\\s+");version[0]=arrayOfString[2];//KernelVersionlocalBufferedReader.close();} catch (IOException e) {}version[1] = Build.VERSION.RELEASE;// firmware versionversion[2]=Build.MODEL;//modelversion[3]=Build.DISPLAY;//system versionreturn version;}

版本信息里面还包括型号等信息。

七、MAC地址和开机时间：

public String[] getOtherInfo(){String[] other={"null","null"};        WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);        WifiInfo wifiInfo = wifiManager.getConnectionInfo();        if(wifiInfo.getMacAddress()!=null){        other[0]=wifiInfo.getMacAddress();} else {other[0] = "Fail";}other[1] = getTimes();        return other;}private String getTimes() {long ut = SystemClock.elapsedRealtime() / 1000;if (ut == 0) {ut = 1;}int m = (int) ((ut / 60) % 60);int h = (int) ((ut / 3600));return h + " " + mContext.getString(R.string.info_times_hour) + m + " "+ mContext.getString(R.string.info_times_minute);}

最后贴一个格式化数据的方法：

public String formatSize(long size) {String suffix = null;float fSize=0;if (size >= 1024) {suffix = "KB";fSize=size / 1024;if (fSize >= 1024) {suffix = "MB";fSize /= 1024;}if (fSize >= 1024) {suffix = "GB";fSize /= 1024;}} else {fSize = size;}java.text.DecimalFormat df = new java.text.DecimalFormat("#0.00");StringBuilder resultBuffer = new StringBuilder(df.format(fSize));if (suffix != null)resultBuffer.append(suffix);return resultBuffer.toString();}

保留两位小数。

三、Android获取手机和系统版本等信息的代码

有时候需要统计手机的型号和版本号，利用程序可以获取到相应的手机信息，对比两部手机发现，厂商不同，某个信息显示方式也不尽相同，具体见：

String phoneInfo = "Product: " + android.os.Build.PRODUCT;        phoneInfo += ", CPU_ABI: " + android.os.Build.CPU_ABI;        phoneInfo += ", TAGS: " + android.os.Build.TAGS;        phoneInfo += ", VERSION_CODES.BASE: " + android.os.Build.VERSION_CODES.BASE;        phoneInfo += ", MODEL: " + android.os.Build.MODEL;        phoneInfo += ", SDK: " + android.os.Build.VERSION.SDK;        phoneInfo += ", VERSION.RELEASE: " + android.os.Build.VERSION.RELEASE;        phoneInfo += ", DEVICE: " + android.os.Build.DEVICE;        phoneInfo += ", DISPLAY: " + android.os.Build.DISPLAY;        phoneInfo += ", BRAND: " + android.os.Build.BRAND;        phoneInfo += ", BOARD: " + android.os.Build.BOARD;        phoneInfo += ", FINGERPRINT: " + android.os.Build.FINGERPRINT;        phoneInfo += ", ID: " + android.os.Build.ID;        phoneInfo += ", MANUFACTURER: " + android.os.Build.MANUFACTURER;        phoneInfo += ", USER: " + android.os.Build.USER;        // Toast.makeText(this, phoneInfo, Toast.LENGTH_LONG).show();        TextView t = (TextView) findViewById(R.id.main_phoneinfo);        t.setText(phoneInfo);
