I am working on a twitter based app and am trying to incorporate Android's built-in Account support for Twitter. The following code works to popup the confirmation dialog for my app to access twitter but I am unsure of what to pass in as the authenticationType. Any help would be appreciated. I've googled all over the place and can't seem to find the correct answer. It goes in place of "oauth" below.

AccountManager am = AccountManager.get(this);
Account[] accts = am.getAccountsByType(TWITTER_ACCOUNT_TYPE);
if(accts.length > 0) {
    Account acct = accts[0];
    am.getAuthToken(acct, "oauth"/*what goes here*/, null, this, new AccountManagerCallback<Bundle>() {

    @Override
    public void run(AccountManagerFuture<Bundle> arg0) {
        try {
                     Bundle b = arg0.getResult();  
                     Log.e("TrendDroid", "THIS AUTHTOKEN: " + b.getString(AccountManager.KEY_AUTHTOKEN));  
                } catch (Exception e) {  
                     Log.e("TrendDroid", "EXCEPTION@AUTHTOKEN");  
                }  
    }}, null);
}
