Error with adding text messaging to Ribbit app

I'm trying to add text messaging to the Ribbit App. I've made a button in the action bar that takes the user to a new activity. In that activity the user can put text into a editText then when they click on the button they are able to choose a recipient. When the user clicks the recipient then sends the message my app crashes. Is anybody able to help me with this? I am getting this in my logcat:

This is my createMessage() method from RecipientsActivity:

protected ParseObject createMessage(){ ParseObject message = new ParseObject(ParseConstants.CLASS_MESSAGES); message.put(ParseConstants.KEY_SENDER_ID, ParseUser.getCurrentUser().getObjectId()); message.put(ParseConstants.KEY_SENDER_NAME, ParseUser.getCurrentUser().getUsername()); message.put(ParseConstants.KEY_RECIPIENT_IDS, getRecipientIds());

    message.put(ParseConstants.KEY_FILE_TYPE, mFileType);

    if (mFileType.equals(ParseConstants.TYPE_TEXT)) {
        message.put(ParseConstants.KEY_MESSAGE, mEditMessage);
        message.put(ParseConstants.KEY_FILE_TYPE, ParseConstants.TYPE_TEXT);
        return message;
    }else{



        byte[] fileBytes = FileHelper.getByteArrayFromFile(this, mMediaUri);

        if (fileBytes == null) {
            return null;
        }else {
            if(mFileType.equals(ParseConstants.TYPE_IMAGE)) {
                fileBytes = FileHelper.reduceImageForUpload(fileBytes);
            }
            String fileName = FileHelper.getFileName(this, mMediaUri, mFileType);
            ParseFile file = new ParseFile(fileName, fileBytes);
            message.put(ParseConstants.KEY_FILE, file);
            return message;
        }
    }
}
