Android Get mobile Info

Many of the information on the Android system can be obtained through the/proc directory, such as

Cat/proc/cpuinfo Getting CPU Information

Cat/proc/meminfo Getting memory information

This information is saved in text format, can be read through IO stream, relatively simple, here to consider that some content is not saved as text, disk information

We implement a Linux command parser through code to obtain the information

The instruction parser is as follows:

public class Cmdexecutor {/** * Execute command * @param cmd       command parameter * @param workdir   current directory (that is, execute instruction pwd See directory) * @return */public  Synchronized string run (string[] cmd, string workdir) {string result = ""; InputStream is = null;try {Processbuilder Builder = new Processbuilder (cmd); Textutils.isempty (Workdir)) {builder.directory (new File (Workdir));   Set the execution instruction directory Builder.redirecterrorstream (); Process process = Builder.start ();      Execute instruction is = Process.getinputstream (); byte[] buf = new Byte[1024];int len = 0;while (len = Is.read (BUF))! =-1) {result + = N EW String (buf, 0, Len);}}} catch (Exception e) {return null;} Finally{if (is! = null) {try {is.close ();} catch (IOException e) {e.printstacktrace ();}}} return result;}}

To obtain the mobile phone Information tool class:

public class Getphoneinfoutil {//Get kernel version, GCC version, etc. public String fetch_version_info () {string result = NULL; Cmdexecutor CmdExe = new Cmdexecutor (); string[] args = {"/system/bin/cat", "/proc/version"};   "/system/bin/cat" instruction absolute path result = Cmdexe.run (args, "system/bin/"); Specified instruction execution directory, above absolute path writable relative path "cat" return result; Get CPU Information public string Fetch_cpu_info () {string result = NULL; Cmdexecutor CmdExe = new Cmdexecutor (); string[] args = {"/system/bin/cat", "/proc/cpuinfo"};result = Cmdexe.run (args, "/system/bin/"); return result; To add a permission: android.permission.read_phone_state//operator Information public String Fetch_tel_status (context context) {string result = Null Telephonymanager TM = (Telephonymanager) context.getsystemservice (Context.telephony_service); String str = ""; str + = "DeviceId (IMEI) =" + Tm.getdeviceid () + "\ n"; str + = "Devicesoftwareversion =" + Tm.getdevicesoft Wareversion () + "\ n"; int mcc = Context.getresources ().

for System.getproperty (), refer tothe System.getproperty () method can get the value
