how possible achieve downloading .mp3 file server , store locally in app? later, can played local storage. on appreciated.

thank you.

you can use method:

static void downloadfile(string dwnload_file_path, string filename,         string pathtosave) {     int downloadedsize = 0;     int totalsize = 0;      try {         url url = new url(dwnload_file_path);         httpurlconnection urlconnection = (httpurlconnection) url                 .openconnection();          urlconnection.setrequestmethod("post");         urlconnection.setdooutput(true);          // connect         urlconnection.connect();          file mydir;         mydir = new file(pathtosave);         mydir.mkdirs();          // create new file, save downloaded file          string mfilename = filename;         file file = new file(mydir, mfilename);          fileoutputstream fileoutput = new fileoutputstream(file);          // stream used reading data internet         inputstream inputstream = urlconnection.getinputstream();          // total size of file downloading         totalsize = urlconnection.getcontentlength();          // runonuithread(new runnable() {         // public void run() {         // pb.setmax(totalsize);         // }         // });          // create buffer...         byte[] buffer = new byte[1024];         int bufferlength = 0;          while ((bufferlength = inputstream.read(buffer)) > 0) {             fileoutput.write(buffer, 0, bufferlength);             downloadedsize += bufferlength;             // update progressbar //             // runonuithread(new runnable() {             // public void run() {             // pb.setprogress(downloadedsize);             // float per = ((float)downloadedsize/totalsize) * 100;             // cur_val.settext("downloaded " + downloadedsize + "kb / " +             // totalsize + "kb (" + (int)per + "%)" );             // }             // });         }         // close output stream when complete //         fileoutput.close();         // runonuithread(new runnable() {         // public void run() {         // // pb.dismiss(); // if want close it..         // }         // });      } catch (final malformedurlexception e) {         // showerror("error : malformedurlexception " + e);         e.printstacktrace();     } catch (final ioexception e) {         // showerror("error : ioexception " + e);         e.printstacktrace();     } catch (final exception e) {         // showerror("error : please check internet connection " + e);     } }

call method this:

string sdcardroot = environment.getexternalstoragedirectory()                             .tostring();                     utils.downloadfile("http://my_audio_url/my_file.mp3", "my_file.mp3",                             sdcardroot+"/myaudiofolder");

for playback:

string sdcardroot = environment.getexternalstoragedirectory()                         .tostring(); string audiofilepath = sdcardroot + "/myaudiofolder/my_file.mp3"; mediaplayer mplayer = new mediaplayer(); try {                 mplayer.setdatasource(audiofilepath);                 mplayer.prepare();                 mplayer.start();             } catch (ioexception e) {                 log.e("audio playback", "prepare() failed");             }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
