How to use modern authentication instead of basic authentication in ews-android-api

[arunsankar8]

Hi @alipov

This is not a issue, just asking some tips and support from you. I have been using the ews-android-api in my application to get the events etc.. According to the docs, the basic authentication will be deprecated on the coming October 2020. I believe the basic authentication have been using, So how can I use modern authentication instead of basic authentication in my application to continue using the ews-android-api in my projects. Looking forward to your suggestions and support.

The sample code used for login

  public void login() throws Exception {
        ExchangeService service = createService();
        Mailbox mailbox = new Mailbox(user.getMailbox());
        FolderId folderId = new FolderId(WellKnownFolderName.Calendar, mailbox);
        CalendarFolder folder = CalendarFolder.bind(service, folderId);
    }

Hi @arunsankar8,

Since the question relates to the core functionality (rather than to Android adjustments), I'd suggest you to direct it to ews-java maintainers.

Thanks @alipov.

Hi @alipov,
I have raised the same question in the ews-java repo, but there aren't any responses till now from their side. Is there any way to implement modern authentication in the application you know of, the steps described in Microsoft documentation to implement modern authentication is for C#. Can you please take a look at it. Can we implement modern authentication in android.? It will be really helpful if you could help.

Hi @arunsankar8,

I don't have any immediate plans implementing modern authentication support.

I guess you can look into microsoft-authentication-library-for-android or AppAuth-Android and see if it can be used to easily add such support. Also, it seems that some attempts to add OAuth2 support were made here and here.

Hi @alipov the MSAL library from the above documentation is used for authentication in Microsoft Graph API, can we use that for the EWS authentication also?

https://docs.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-authenticate-an-ews-application-by-using-oauth This was the Microsoft documentation on implementing the modern auth, can we use this in our Android application? Any idea on these

[alipov]

Perhaps. I don't have any prior experience with this library.
