how current latitude , longitude in android2.3.3?

i try follow this can't run programs.

my code

    latview = (textview)findviewbyid(r.id.lattext);     lngview = (textview)findviewbyid(r.id.lngtext);     locationmanager lm = (locationmanager)getsystemservice(context.location_service);      location location = lm.getlastknownlocation(locationmanager.gps_provider);     double longitude = location.getlongitude();     double latitude = location.getlatitude();

in android manifest put this.

<uses-permission android:name="android.permission.internet" />  <uses-permission android:name="android.permission.access_coarse_location" /> <uses-permission android:name="android.permission.access_fine_location" />

please help. thanks.

this have in application find device current location, works fine:

public class mylocationactivity extends activity implements locationlistener {     private locationmanager mgr;     private string best;     public static double mylocationlatitude;     public static double mylocationlongitude;      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);          mgr = (locationmanager) getsystemservice(location_service);          dumpproviders();          criteria criteria = new criteria();          best = mgr.getbestprovider(criteria, true);         log.d("best provider", best);          location location = mgr.getlastknownlocation(best);         dumplocation(location);              //may intent here     }      public void onlocationchanged(location location) {         // todo auto-generated method stub         dumplocation(location);      }      public void onproviderdisabled(string provider) {         // todo auto-generated method stub      }      public void onproviderenabled(string provider) {         // todo auto-generated method stub      }      public void onstatuschanged(string provider, int status, bundle extras) {         // todo auto-generated method stub      }      @override     protected void onpause() {          super.onpause();         mgr.removeupdates(this);     }      @override     protected void onresume() {          super.onresume();         mgr.requestlocationupdates(best, 15000, 1, this);     }      private void dumplocation(location l) {          if (l == null) {              mylocationlatitude = 0.0;             mylocationlongitude = 0.0;         } else {              mylocationlatitude = l.getlatitude();             mylocationlongitude = l.getlongitude();         }     }      private void dumpproviders() {          list<string> providers = mgr.getallproviders();         (string p : providers) {              dumpproviders(p);         }     }      private void dumpproviders(string s) {          locationprovider info = mgr.getprovider(s);         stringbuilder builder = new stringbuilder();         builder.append("name: ").append(info.getname());     }  }

here mylocationlatitude , mylocationlongitude gives values of lat , long needed.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
