Unable to send gmail e-mail using Javamail and Account Manager (Error 400)

I am using Android's Account Manager to authenticate my way into Gmail so I can send an e-mail from the device.

During the send process, it appears (from the logs) that everything connects and authenticates okay, but it gives me the following error:

E/SMTP TRANSPORT ERROR﹕ 334 eyJzdGF0dXMiOiI0MDAiLCJzY2hlbWVzIjoiQmVhcmVyIiwic2NvcGUiOiJodHRwczovL21haWwuZ29vZ2xlLmNvbS8ifQ==
    class javax.mail.MessagingException

Which when decoded reads:

{"status":"400","schemes":"Bearer","scope":"https://mail.google.com/"}

From other SO questions, I've seen that this means that the token is expired. However, this is NOT the case in my case, I have tried invalidating the token and getting a new one; same problem.

Here's how I authenticate:

 am = AccountManager.get(this);




        options = new Bundle();
        Account me = null;

        Account[] accounts = am.getAccounts();
        for(Account a: accounts){
            if(a.name.equals(TEST_ACCOUNT_EMAIL) && a.type.equals("com.google")){
                me = a;
            }
        }
        if (me != null){
            am.getAuthToken(me, "oauth2:https://mail.google.com/", null, this, new OnTokenAcquired(), null);
        }

Here's the full log which appears after I click to send a test e-mail message to myself (note authentication success)

I am not aware that an OAuth2 token is considered a valid Gmail password for use via JavaMail. – Chintz
@Chintz I'm using the implementation specified here: #14682593 – Phalanger
Hey @Rohan, Yes I did get it working using this code: https://mcmap.net/q/698751/-javamail-api-in-android-using-xoauth. I did get a that 334 error I think, I too thought I was because the token had expired, but which was not the case. The case was that I was using the wrong SCOPE. However, I just checked my code and I'm using the same SCOPE as you are... – Ballroom

JavaMail 1.5.2 will include OAuth 2 support. You can try the SNAPSHOT release now.

Do you have an example implementation in Android I could look at? – Phalanger
Sorry, no, Android isn't Java. – Godliman
