1.获取手机安装的应用信息（排除系统自带）：

Java代码：

 1 private String getAllApp() {   2             String result = "";   3             List<PackageInfo> packages = getPackageManager().getInstalledPackages(0);   4             for (PackageInfo i : packages) {   5                 if ((i.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0) {   6                     result += i.applicationInfo.loadLabel(getPackageManager()).toString() + ",";   7                 }   8             }   9             return result.substring(0, result.length() - 1);  10     }  

以字符串的形式返回应用的名字app1,app2,app3,......,appn中间的以","分开。当然还可以得到包名，icon图标，等等 。

 

2.获取手机可用内存和总内存：

Java代码：

 1     private String[] getTotalMemory() {   2            String[] result = {"",""};  //1-total 2-avail   3            ActivityManager.MemoryInfo mi = new ActivityManager.MemoryInfo();     4            mActivityManager.getMemoryInfo(mi);     5            long mTotalMem = 0;   6            long mAvailMem = mi.availMem;   7            String str1 = "/proc/meminfo";   8            String str2;   9            String[] arrayOfString;  10            try {  11                FileReader localFileReader = new FileReader(str1);  12                BufferedReader localBufferedReader = new BufferedReader(localFileReader, 8192);  13                str2 = localBufferedReader.readLine();  14                arrayOfString = str2.split("\\s+");  15                mTotalMem = Integer.valueOf(arrayOfString[1]).intValue() * 1024;  16                localBufferedReader.close();  17            } catch (IOException e) {  18                e.printStackTrace();  19            }  20            result[0] = Formatter.formatFileSize(this, mTotalMem);  21            result[1] = Formatter.formatFileSize(this, mAvailMem);  22            Log.i(TAG, "meminfo total:" + result[0] + " used:" + result[1]);  23            return result;  24        }  

 手机的内存信息主要在/proc/meminfo文件中，其中第一行就是总内存，而剩余内存可通过 ActivityManager.MemoryInfo得到。

 

3.手机CPU信息

Java代码：

 1     private String[] getCpuInfo() {   2             String str1 = "/proc/cpuinfo";   3             String str2 = "";   4             String[] cpuInfo = {"", ""};  //1-cpu型号  //2-cpu频率   5             String[] arrayOfString;   6             try {   7                 FileReader fr = new FileReader(str1);   8                 BufferedReader localBufferedReader = new BufferedReader(fr, 8192);   9                 str2 = localBufferedReader.readLine();  10                 arrayOfString = str2.split("\\s+");  11                 for (int i = 2; i < arrayOfString.length; i++) {  12                     cpuInfo[0] = cpuInfo[0] + arrayOfString[i] + " ";  13                 }  14                 str2 = localBufferedReader.readLine();  15                 arrayOfString = str2.split("\\s+");  16                 cpuInfo[1] += arrayOfString[2];  17                 localBufferedReader.close();  18             } catch (IOException e) {  19             }  20             Log.i(TAG, "cpuinfo:" + cpuInfo[0] + " " + cpuInfo[1]);  21             return cpuInfo;  22         }  

和内存信息同理，cpu信息可通过读取/proc/cpuinfo文件来得到，其中第一行为cpu型号，第二行为cpu频率。

 

4.获取手机MAC地址：

Java代码：

1     private String getMacAddress(){  2             String result = "";  3             WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);  4             WifiInfo wifiInfo = wifiManager.getConnectionInfo();  5             result = wifiInfo.getMacAddress();  6             Log.i(TAG, "macAdd:" + result);  7             return result;  8     }  

MAC地址比较容易，直接通过WifiManager得到。

 

4.IMEI号，IESI号，手机型号等：

Java代码：

1     private void getInfo() {  2             TelephonyManager mTm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);  3             String imei = mTm.getDeviceId();  4             String imsi = mTm.getSubscriberId();  5             String mtype = android.os.Build.MODEL; // 手机型号  6             String numer = mTm.getLine1Number(); // 手机号码，有的可得，有的不可得  7         }  

 

5.获取手机屏幕高度：

Java代码：

 1     private void getWeithAndHeight(){   2            //这种方式在service中无法使用，   3            DisplayMetrics dm = new DisplayMetrics();   4            getWindowManager().getDefaultDisplay().getMetrics(dm);   5            String width = dm.widthPixels;              //宽   6            String height = dm.heightPixels;           //高   7        8            //在service中也能得到高和宽   9            WindowManager mWindowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);  10            width = mWindowManager.getDefaultDisplay().getWidth();  11            height = mWindowManager.getDefaultDisplay().getHeight();  12        }
