Deleteing files now complies with api v2.1

[TomRaybould]

The HttpConnector class is still using the old v2.0 web api for the camera, for deleting images, and does not currently work this way. This commit changes the HttpConnector logic so that it can delete files off the camera using the v2.1 web api. This requires a different callback with an array of multiple image paths which I have created "HttpDeleteFileListener".

I haven't heard anything from the devs in this project. @kkushimoto and @shohara is there anything I can do to help this pull request along? I didn't see anything in terms of guidelines for pull requests on this project. I tried to keep the added delete functionality in-line with what is already in the code base. Any feedback is appreciated! Thank you!

@TomRaybould and @Kyusung4698, thanks for the PR. Can you send me and @jcasman an email with information on the plug-in you're building? We want to relay this information on to the team at RICOH when we ask them the status of the PR to help get their attention. Our email is [email protected] and [email protected] We don't work for RICOH, but we talk to people there from time to time.

It's not work for me.
I use the example theta-api2.1-android-sdk
and i already fix the parameters name from " fileUri" to "fileUrls" as below:

HttpURLConnection postConnection = createHttpConnection("POST", "/osc/commands/execute");
JSONObject input = new JSONObject();
String responseData;
mHttpEventListener = listener;
InputStream is = null;

try {
    // send HTTP POST
    input.put("name", "camera.delete");
    JSONObject parameters = new JSONObject();
    parameters.put("fileUrls", "image");
    input.put("parameters", parameters);

    OutputStream os = postConnection.getOutputStream(); 
    os.write(input.toString().getBytes());
    postConnection.connect();
    os.flush();
    os.close();

    is = postConnection.getInputStream(); <=====IOException here
    responseData = InputStreamToString(is);

Hey @Jackdea,

So in all honesty, since making this PR I have since switched jobs and no longer work on anything related to Theta, that being said I think I can still help you here...

First the issue..
v2.0's API
needs only one file URI to delete a given file.

v2.1's API
need a json array of fileId to delete one of more images.

The solution..

It looks like above you are trying to delete a file that is called "image" so in order to get this to work you need to first put that fileId into a JSONArray and then add the array as a param.

 input.put("name", "camera.delete");
JSONObject parameters = new JSONObject();
JSONArray fileIdArray = new JSONArray();
fileIdArray.put("image")
parameters.put("fileUrls", fileIdArray);
input.put("parameters", parameters);

Extra tip:
Also ideal you should change the hardcoded "image" string to a variable so you can pass any file you want to delete to this method. I realize you probably know this and you were just hardcoding for the example, but just my 2 cents.

Thanks~~~ It's work!!

        input.put("name", "camera.delete");
        JSONObject parameters = new JSONObject();
        JSONArray fileIdArray = new JSONArray();
        fileIdArray.put(deletedFileId);
        parameters.put("fileUrls", fileIdArray);
        input.put("parameters", parameters);
