[android help] How to provide progressive audio streaming with progressiv download in Box Api

What i want to do in my project is to play audio songs which are inside my Box account for that i am using box api . As i know we can not provide direct audio streaming for audio files in Box api for that i am trying to implement progressive download and playing audio file from sd card . i know i can play song inside on complete method of download but this is taking more time to download and than playing file . for that what i did i wrote my code for playing audio inside on progress method of downloading file but this method is getting called so many times because of that same song is playing multiple time at a time.

So is there any way to write code for progressive audio playing in Box api .if yes where should i write that ?

* Download a file and put it into the SD card. In your app, you can put the file wherever you have access to.

                File file = new File(PATH);
                file.mkdirs();
                final java.io.File destinationFile = new java.io.File(PATH + "/"
                        + URLEncoder.encode(items[position].name));
             /*   final java.io.File destinationFile = new java.io.File(Environment.getExternalStorageDirectory() + "/"
                                                                      + URLEncoder.encode(items[position].name));*/
