str refers response get. upon printing in logcats, got following response saying invalid hostname. there wrong hostname i've put in code? please new using rest style apis

may use httpclient here may helps you

          httpclient httpclient = new defaulthttpclient();     httppost httppost = new httppost(strurl);     if (mheader != null) {         (header header : mheader) {             httppost.addheader(header);         }     }     try {         multipartentity entity = new multipartentity(httpmultipartmode.browser_compatible);         if (namevaluepair != null) {             contentbody cb;             for(namevaluepair value: namevaluepair){                 cb =  new stringbody(value.getvalue(),"", null);                 entity.addpart(value.getname(), cb);             }         }         if(filepath != null && filepath.length() > 0){             file f = new file(filepath);             entity.addpart("uploadedfile", new filebody(f));         }         httppost.setentity(entity);          httpresponse httpresponse = httpclient.execute(httppost);         response = entityutils.tostring(httpresponse.getentity());     } catch (clientprotocolexception e) {         e.printstacktrace();         //display();       } catch (ioexception e) {         e.printstacktrace();         //display();                 }      if (misprogress)         progress.dismiss();     return response; }

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...
