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 }
