Go to: Get some information about the Android mobile phone

Come and have a look at the Android games!

1. Obtain the app information installed on your mobile phone (excluding the app information that comes with the system ):

Java code:

 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     }  

Return the app1, app2, app3,..., and appn separated by "," in the form of a string. Of course, you can also get the package name, icon, and so on.

 

2. Get the available memory and total memory of the mobile phone:

Java code:

 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        }  

The memory information of the mobile phone is mainly in the/proc/meminfo file. The first line is the total memory, and the remaining memory can be obtained through ActivityManager. MemoryInfo.

 

3. Mobile phone CPU Information

Java code:

1 private String [] getCpuInfo (){
2 String str1 = "/proc/cpuinfo ";
3 String str2 = "";
4 String [] cpuInfo = {"", ""}; // 1-cpu model // 2-cpu frequency
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}

Similar to the memory information, the cpu information can be obtained by reading the/proc/cpuinfo file, where the first act is the cpu model and the second act is the cpu frequency.

 

4. Obtain the MAC address of the mobile phone:

Java code:

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     }  

The MAC address is relatively easy and can be obtained directly through WifiManager.

 

4. IMEI, IESI, and mobile phone model:

Java code:

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; // Mobile Phone MODEL
6 String numer = mTm. getLine1Number (); // mobile phone number, which is available or unavailable
7}

 

5. Get the screen height of the mobile phone:

Java code:

1 private void getWeithAndHeight (){
2 // This method cannot be used in the service,
3 DisplayMetrics dm = new DisplayMetrics ();
4 getWindowManager (). getDefaultDisplay (). getMetrics (dm );
5 String width = dm. widthPixels; // width
6 String height = dm. heightPixels; // high
7
8 // the height and width can also be obtained in the service
9 WindowManager mWindowManager = (WindowManager) getSystemService (Context. WINDOW_SERVICE );
10 width = mWindowManager. getDefaultDisplay (). getWidth ();
11 height = mWindowManager. getDefaultDisplay (). getHeight ();
12}
