storing multiple ParseFile objects in single ParseObject

ANDROID

This is how I store ParseFile List into ParseObject

ParseObject pObject = new ParseObject();    
ArrayList<ParseFile> pFileList = new ArrayList<ParseFile>();
    for (String thumbPath : thumbList) {
       byte[] imgData = convertFileToByteArray(thumbPath);
       ParseFile pFile = new ParseFile("mediaFiles",imgData);
       pFileList.add(pFile);    
    }

       pObject.addAll("mediaFiles", pFileList); 
       pObject.saveEventually();

after this call it does not show the inserted row in data browser, although it shows rowcount of 1 in table

This is how i retrieve it and get the first image from the list

List<ParseFile> pFileList = (ArrayList<ParseFile>) pObject.get("mediaFiles");
    if (!pFileList.isEmpty()) {
          ParseFile pFile = pFileList.get(0);
          byte[] bitmapdata = pFile.getData();  // here it throws error
          bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);
    }

I am able to retrieve all String columns , but for "mediaFiles" column while doing getData() I get thisexception. com.parse.ParseException: Target host must not be null, or set in parameters.

I observed that in ParseFile, data and url is null.

Can somebody please show me the code on how to store and retrieve multiple ParseFile objects into single ParseObject?

Cover the byte[] bitmapdata = pFile.getData(); line of code under try catch. It worked for me!

Try to do this thing as upload image one after another,

   public void UploadImageToParse(String img_path, final String filedName, String Filename) {
        //String img_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + "P200913_1908.jpg";

        final File file = new File(img_path);
        try {
            FileInputStream fileInputStream = new FileInputStream(file);
            Bitmap bitmap = BitmapFactory.decodeStream(fileInputStream);
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] image_array = baos.toByteArray();
            final ParseFile parsefile = new ParseFile(Filename, image_array);
            parsefile.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    if (e != null) {

                    } else {

                        frameInfo.put(filedName, parsefile);
                        frameInfo.saveInBackground(new SaveCallback() {
                            @Override
                            public void done(ParseException e) {
                                if (e == null) {
                                    DebugLog.e("" + e);

                                } else {
                                    fileUploadStatusUpdater.onFailure();
                                    DebugLog.e("File Upload Fail");
                                }
                            }
                        });
                        /*ParseUser user = ParseUser.getCurrentUser();
                        user.put(filedName, parsefile);
                        user.saveInBackground(new SaveCallback() {
                            @Override
                            public void done(ParseException e) {
                                Log.e("", "" + e);
                            }
                        });*/
                    }
                }

            }, new ProgressCallback() {
                @Override
                public void done(Integer integer) {
                    if (integer == 100) {
                        DebugLog.e("File Upload Completed");
                        fileUploadStatusUpdater.onSuccess();
                    }
                }
            });
        } catch (Exception e) {
            DebugLog.e("Fis" + e);
            fileUploadStatusUpdater.onFailure();
        }

final ParseFile parseFile1 = new ParseFile("poll_image1.jpg",scaleImage("poll_image1",imageList.get(contestImage1.getId())));
                        final ParseFile parseFile2 = new ParseFile("poll_image2.jpg",scaleImage("poll_image2",imageList.get(contestImage2.getId())));
                        parseFile1.save(); parseFile2.save();

                        List<ParseFile> listOfFiles = new ArrayList<ParseFile>();
                        listOfFiles.add(parseFile1);
                        listOfFiles.add(parseFile2);


                        ParseObject jobApplication = new ParseObject("Poll");
                        jobApplication.put("poll_question", contestQuestion.getText().toString());
                        jobApplication.put("poll_type_id", 1);
                        ParseUser currentUser = ParseUser.getCurrentUser();
                        jobApplication.put("user", currentUser);
                        jobApplication.put("parseFile", listOfFiles);
                        jobApplication.saveInBackground(new SaveCallback() {

                            @Override
                            public void done(ParseException arg0) {

                            }
                        });

Above code does multi upload, but ParseObject called only after Two save() method. Because of two save method UI getting Stuck. How to fix it!

Try uploading the ParseFiles using the save method before associating them with the Parse Object.
