How to download an image from server side to android using bytearray?

Question

My Android colleague wants an image to be sent from Java Server side code, I tried using byte-array-output stream, which is the best way to send an image to Android client. How should the android code be to receive byte-array.

I have done this things by byte array. This is my code for your reference :

String base64String = (String)sp.toString();
byte[] mediaData = Base64.decode(base64String, 0);                              write(notesList.get(position).getContent(), mediaData);
                                        File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),
                                                notesList.get(position).getContent());
                                        Uri path = Uri.fromFile(file);
                                        if(notesList.get(position).getContent().contains(".pdf"))
                                        {
                                            Intent pdfOpenintent = new Intent(Intent.ACTION_VIEW);
                                            pdfOpenintent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                                            pdfOpenintent.setDataAndType(path, "application/pdf");
                                            try {
                                                context.startActivity(pdfOpenintent);
                                            } catch (ActivityNotFoundException e) {
                                            }
                                        }
                                        else if(notesList.get(position).getContent().contains(".jpg") || notesList.get(position).getContent().contains(".jpeg") || notesList.get(position).getContent().contains(".png"))
                                        {
                                            Intent intent = new Intent();
                                            intent.setAction(Intent.ACTION_VIEW);
                                            intent.setDataAndType(Uri.parse("file://" + path), "image/*");
                                            context.startActivity(intent);
                                        }
                                        else if(notesList.get(position).getContent().contains(".xls"))
                                        {
                                            PackageManager packageManager = context.getPackageManager();
                                            Intent intent = new Intent(Intent.ACTION_VIEW);
                                            intent.setType("application/*");
                                            List list = packageManager.queryIntentActivities(intent,
                                                PackageManager.MATCH_DEFAULT_ONLY);


                                            if (list.size() > 0) {
                                                intent.setDataAndType(path, "application/*");
                                                context.startActivity(intent);
                                            }
                                        }

Here, sp is the response from the server.
