android - How to connect local server to GCM client application? -

i have built gcm application , local server in php. want store registration id of client server database. running server on localhost. tried use ipv4 address 192.168.x.y/gcm/save.php(it's running fine , it's identifying files in c:/wamp/www when run on computer) , connected both local computer , android application same wifi network isn't working. how can send regid local server running on computer? here utils.java file:

public class utils {  static context context; public static final string tag = "utils"; public static final string username = "username";  public static final string property_reg_id = "registration_id"; private static final string property_app_version = "appversion";  public utils(context context) {     utils.context = context; }  public sharedpreferences getgcmpreferences() {     return context.getsharedpreferences(((actionbaractivity) context)             .getclass().getsimplename(), context.mode_private); }  public void savepreferences(string key, string value) {     final sharedpreferences prefs = getgcmpreferences();     log.i(tag, key + " : " + value);     sharedpreferences.editor editor = prefs.edit();     editor.putstring(key, value);     editor.commit(); }  public string getfrompreferences(string key) {     final sharedpreferences prefs = getgcmpreferences();     string value = prefs.getstring(key, "");     if (value.isempty()) {         log.i(tag, key + " not found.");         return "";     }     return value; }  string getregistrationid() {     final sharedpreferences prefs = getgcmpreferences();     string registrationid = prefs.getstring(property_reg_id, "");     if (registrationid.isempty()) {         log.i(tag, "registration not found.");         return "";     }     // check if app updated; if so, must clear registration id     // since existing regid not guaranteed work new     // app version.     int registeredversion = prefs.getint(property_app_version,             integer.min_value);     int currentversion = getappversion();     if (registeredversion != currentversion) {         log.i(tag, "app version changed.");         return "";     }     return registrationid; }  static int getappversion() {     try {         packageinfo packageinfo = context.getpackagemanager()                 .getpackageinfo(context.getpackagename(), 0);         return packageinfo.versioncode;     } catch (namenotfoundexception e) {         // should never happen         throw new runtimeexception("could not package name: " + e);     } }  public void storeregistrationid(string regid) {     final sharedpreferences prefs = getgcmpreferences();     int appversion = utils.getappversion();     log.i(tag, "saving regid on app version " + appversion);     log.i(tag, "reg id : " + regid);     sharedpreferences.editor editor = prefs.edit();     editor.putstring(property_reg_id, regid);     editor.putint(property_app_version, appversion);     editor.commit(); }  public string getcurrentipaddress() {     //return "http://192.168.1.37/safety_app/save_reg_id.php";     return "http://192.168.14.198/safety_app/save_reg_id.php"; }  public void showtoast(final string txt) {     ((activity) context).runonuithread(new runnable() {         public void run() {             toast.maketext(context, txt, toast.length_long).show();         }     });  }  }
