Android Question Connecting to Site Using oAuth2.0

Hi, I'm trying to connect to a site that has OAuth2.0 working. I have received the following documentation

- https://docs.google.com/document/d/12WFbF93Sw0b_3iBippvLvx4swbJQ47eu7fT0VLyvGUw/edit#

I don't understand what

1. the "scope" string represents and

2. what is the significance of the Redirect URI. They have given me a web address that is registered in my name but I don't do anything with it except for using it to host a test Web Site

They have given me a ClientID and ClientSecret, an Authorization Token and an Access Token but I can't get it to give me the access code

The app brings up their web site login page, then gives me the error message

"java.lang.Exception: Sub service_start signature does not match expected signature"

Thanks in anticipation

PS I have the GMail Contacts app working

Apologies for my lack of systems programming knowledge, I've always done business stuff.

This is the complete Log, as you can see it falls over on Line 31 (End Sub of Service_Create)
but the Log says Sub service_start signature ..................

--------------------------------------------------
** Activity (main) Create, isFirst = true **


** Activity (main) Resume **


Starting Job: GetAccessToken


** Service (httputilsservice) Create **


** Service (httputilsservice) Start **


An error occurred:


(Line: 31) End Sub
java.lang.Exception: Sub service_start signature does not match expected signature.
public static anywheresoftware.b4a.pc.RemoteObject anywheresoftware.b4a.samples.gmailcontacts.httputilsservice_subs_0._service_start() throws java.lang.Exception

----------------------------------------------------------

Is the subs.txt file of any asistance in the "\Objects\shell\bin\classes" folder

I'm sorry, I don't think that this is what you were after but I don't know how to get it

Regards

Sub Service_Create
    If init = False Then Process_Globals
    If TempFolder = "" Then TempFolder = File.DirInternalCache
    If hcIsInitialized = False Then
        hc.Initialize("hc")
        hcIsInitialized = True
    End If

End Sub
This is the message I get when I run it in Release mode

Thanks Erel, That got thru to the end of the job done for Access Token but

1. I need to tied up my program and ensure the id's etc are all in the right place because I tried many variations and

2. I presume that they need to get back to me about what the "scope" should be. I've emailed them

regards

The return strings I'm getting back from the site are in JSON format rather than xml format. I've tried numerous combinations of the parse function

B4X:
Parser.Initialize(HttpUtils.GetString(url))
            Map1 = Parser.NextValue        .NextArray        .NextObject
            Dim m As Map 'helper map for navigating
            m = Map1.Get("portfolios")
NextValue, NextArray and NextObject but couldn't get a returned file.

I've put the request sent by the app eg

https://portfolio.sharesight.com/ap...d251a94...................???????????????????

into a browser

And get the following returned

{"portfolios":[{"id":553??,"name":"Bowe??????????","default_sale_allocation_method":"fifo","cg_discount":"Self Managed Super Fund","rwtr_rate":33.0,"trader":true,"broker_email_api_enabled":true,"broker_email_key":"johnb?????","financial_year_end_month_id":6,"interest_method":"simple","api_email_notification":"ON","contract_note_email_notification":"ON"}]}

Which is what I expect from their documentation

I get the error message "Task not completed successfully." from the line : Map1 = Parser.NextValue or .NextArray or .NextObject

I've searched the forum but couldn't find any reference to returning JSON formatted files in oAuth2.0
