How to pin a ParseObject with a ParseFile to the Parse Local Datastore in OFFLINE?

Question

I am using the following code to store the ParseObject with a ParseFile. I have enabled Parse local datastore in Application subclass. This code storing an instance of the P

I really liked ashokgujju's solution. In my case, I wanted to save a picture from an Android device in offline mode, so this is what happened to me:

1.- Only by doing that (ashokgujju's solution) will not add a file into your parse table, as SAndroidD pointed out, if you want that, you might use an aftersave Parse Cloud function, something like this:

Parse.Cloud.afterSave("Recordings_or_WhatEverYourTableIs", function(request){
    bytes = request.object.get("data"); //"data" is the name given by  ashokgujju at "obj.put("data", data);"

    if(bytes){
         var file = new Parse.File("myFile.png", bytes); //png or whatever you want
         file.save().then(function(success){
                  request.object.set("record_or_MyColumnWithParseFile", file);
                  request.object.unset("data"); //optional, if you are not going to use this data, it has no meaning keep it there anymore and you will save some space
                  request.object.save();
         },function(error){
                  //error
         }); 
    }

}

That worked like a charm! but...

2.- But only for the Thumbnail, I mean, a very small picture, once I wanted to do the same with a big picture, I faced this:

com.parse.ParseRequest$ParseRequestException: The object is too large -- should be less than 128 kB

It took me a while to realise that, because no errors where shown, just like SAndroidD was saying. I had to add a callback to saveEventually to see it.

  File file = new File(filePath);
    FileInputStream fis = null;
    try {
        fis = new FileInputStream(file);
        byte data[] = new byte[(int) file.length()];
        fis.read(data);

        ParseObject obj = new ParseObject("Recordings");
        obj.put("name", name);          
        obj.put("data", data);
        obj.saveEventually(new SaveCallback() {
                    @Override
                    public void done(ParseException e) {
                        Log.i(MyClass.logName," is it everything ok boy? "+e);
                    }
                });
    } catch (IOException e) {
        e.printStackTrace();
    }

So! to summarize: ashokgujju's cool workaround plus my afterSave function will save any parseFile in offline mode, as long as the file itself is not that big.
