获取手机信息

http://www.cnblogs.com/ayan/archive/2011/12/29/2306824.html

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        }
