java - Transfering Base64 String over Http REST service with JSON response -

-

i have webservice returnds json response , json response contains both plain text , base64 encoded images , consuming service using android app implemented progress bar indicate progress .

implementing progress bar forces me use bufferedinputstream read response , update progress based on app reading .

the problem working fine , progress updating correctly, after collecting response , exiting while loop , try convert string json format using jsonobject. here code snippet 

bufferedinputstream bis = new bufferedinputstream(responseentity.getcontent());             stringbuilder sb = new stringbuilder();             string line = null;             int total = 0 ;             int count = 0 ;             byte[] buffer = new byte[4096];             stringbuffer sbuffer = new stringbuffer();             stringwriter sw = new stringwriter();             string content = new string();              while((count = bis.read(buffer)) > 0){                 content += new string(buffer,charset.defaultcharset());                  total += count;                 publishprogress(""+(int )total*100/this.contentsize);                 log.i("updating",""+(int )total*100/this.contentsize);             }               bis.close();            // string content = new string(sb);             // log.i("serverrawresponse",content);             try {                 log.i("response_content",content.replaceall("\"", ""));                 responsestring = new jsonobject(new jsontokener(content.replaceall("\"", "\\\"")));                 //system.out.println(content);             } catch (jsonexception e) {                 e.printstacktrace();              }

any please

try methods works me

httpresponse wsresponse = httpclient.execute(httppost); string response = getresponsebody(wsresponse.getentity()); jsonobject jobj = new jsonobject(response);  public string getresponsebody(final httpentity entity) throws ioexception, parseexception {          system.out.println("gen start : " + calendar.getinstance().gettimeinmillis());         if (entity == null) {             throw new illegalargumentexception("http entity may not null");         }          inputstream instream = entity.getcontent();          if (instream == null) {             return "";         }          if (entity.getcontentlength() > integer.max_value) {             throw new illegalargumentexception(              "http entity large buffered in memory");         }           stringbuilder buffer = new stringbuilder();          bufferedreader reader = new bufferedreader(new inputstreamreader(instream, http.utf_8));          string line = null;         try {             while ((line = reader.readline()) != null) {                 buffer.append(line);             }          } {             instream.close();             reader.close();         }          return buffer.tostring();      }

python - TypeError: can only concatenate tuple (not "float") to tuple -

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
