android - date time change in onlocation changed -


ive created android app posts web services. supposed check users location , provide relative information gps update in terms of position , date time. rest of functions work fine date time remains same , have no idea why. insight prove helpful.

here of code.

locationlistener

    string lati, longi, alti, timestamp;     float speed;     int counter = 0;      date date = new date();     dateformat dateformat = new simpledateformat("yyyy-mm-dd't'hh:mm:ss'z'");       @override     public void onlocationchanged(location location)      {         // todo auto-generated method stub         log.d("location", "hello world");         lati = string.valueof(location.getlatitude());         longi = string.valueof(location.getlongitude());         alti = string.valueof(location.getaltitude());         speed = location.getspeed();                     timestamp = dateformat.format(date);         counter++;          requestinfo requestinfo = new requestinfo(sessionid, lati, longi, alti, speed, timestamp);         database.addrequest(requestinfo);          textview.settext("" + counter);      }

the requestinfo class sets request web service. constructor provides info needed web service

you create instance date once, when object containing date created. therefore value stays unchanged. instead, move inside onlocationchanged method. this:

@override public void onlocationchanged(location location)  {     ...     date date = new date();     timestamp = dateformat.format(date);     ... }

or can use calendar class , methods gettime() in here

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
