Android obtains the mobile phone information (device IP, OS version etc .) I haven't written anything for a long time. Today I am making a PV log record. I need to record the OS version, WiFi IP address, current time, and so on. I have investigated and shared the following:

Package com. Osip;

Import java. Text. dateformat;

Import java. Text. simpledateformat;

Import java. util. date;

Import Android. App. activity;

Import Wifi. wifiinfo;

Import Wifi. wifimanager;

Import Android. OS. Bundle;

Import Android. widget. textview;

Public class Osip extends activity {

Private textview osversion, clientip, date;

/** Called when the activity is first created .*/

@ Override

Public void oncreate (bundle savedinstancestate ){

Super. oncreate (savedinstancestate );

Setcontentview (R. layout. Main );

Osversion = (textview) findviewbyid (R. Id. OS _version );

Clientip = (textview) findviewbyid (R. Id. client_ip );

Date = (textview) findviewbyid (R. Id. date );

String format = "yyyymmdd. hhmmss. sssz"; // time format with milliseconds and Time Zone

String version = getosversion ();

String IP = getip ();

String cdate = getdate (new date (), format );

Osversion. settext (version );

Clientip. settext (IP );

Date. settext (cdate. substring (0, 22 ));


Private string getdate (date, string format ){

Dateformat = new simpledateformat (format );

Return dateformat. Format (date );


// Obtain the IP address of the device

Private string getip (){

Wifimanager = (wifimanager) getsystemservice (wifi_service );

Wifiinfo = wifimanager. getconnectioninfo ();

Int IPaddress = wifiinfo. getipaddress ();

// Format the IP address, for example, 1828825280 before formatting and after formatting

String IP = string. Format ("% d. % d ",

(IPaddress & 0xff ),

(IPaddress> 8 & 0xff ),

(IPaddress> 16 & 0xff ),

(IPaddress> 24 & 0xff ));

Return IP;


// Obtain the OS version of the device

Private string getosversion (){

String version = Android. OS. Build. version. release;

Return version;
