edit
essential part of repository.
record , save:

string outputfile = environment.getexternalstoragedirectory().                         getabsolutepath() + "/rumor.mp3"; myrecorder = new mediarecorder();                 myrecorder.setaudiosource(mediarecorder.audiosource.mic);                 myrecorder.setoutputformat(mediarecorder.outputformat.default);                 myrecorder.setaudioencoder(mediarecorder.outputformat.amr_nb);                 myrecorder.setoutputfile(outputfile); 

then, start recording...

try {                             myrecorder.prepare();                             myrecorder.start();                         } catch (illegalstateexception e) {                             // start:it called before prepare()                             // prepare: called after start() or before setoutputformat()                             e.printstacktrace();                         } catch (ioexception e) {                             // prepare() fails                             e.printstacktrace();                         } 

when stop recording, save on parse.com in way:

fileinputstream fileinputstream = null;                         file fileobj = new file(outputfile);                         byte[] data = new byte[(int) fileobj.length()];                          try {                             //convert file array of bytes                             fileinputstream = new fileinputstream(fileobj);                             fileinputstream.read(data);                             fileinputstream.close();                         } catch (exception e) {                             e.printstacktrace();                         }                          parsefile parseaudiofile = new parsefile("audiofile.mp3", data);                         parseaudiofile.saveinbackground();                          parseobject parseobject = new parseobject("audiofileclass");                         parseobject.put("audiofile", parseaudiofile);                         parseobject.saveinbackground(new savecallback() {                             public void done(parseexception e) {                                 if (e == null) {                                     toast.maketext(getapplicationcontext(),"audio file saved successfully", toast.length_short).show();                                 } else {                                     toast.maketext(getapplicationcontext(),"error: audio file not saved", toast.length_short).show();                                 }                             }                         }); 

retrieve , play parse.com simple, have used parsequeryadapter. part mp3 file , play it:

parsefile descr = object.getparsefile("audiofile");                 if (descr != null) {                     string audiofileurl = descr.geturl();                     mediaplayer mediaplayer = new mediaplayer();                     mediaplayer.setaudiostreamtype(audiomanager.stream_music);                      try {                         mediaplayer.setdatasource(audiofileurl);                         mediaplayer.prepare();                         mediaplayer.start();                     }                     ...                     ...
