Who should call the confirmCredentials method of the AbstractAccountAuthenticator class when?

Question

I do not understand how the confirmCredentials method confirmCredentials . I have never seen any parameters in the Android interface, such as "Confirm credentials" or something like this, there is only "Create account" and "Delete account".

Used if you want to use the Gmail account on the device as a verification method. NFCSecure uses it when you open the application, forcing you to log into your gmail.

 public void verifyAuth(Bundle b) throws IllegalArgumentException { accountManager.confirmCredentials(getImportantAccount(importantEmail), b, (Activity) c, new OnConfirmed(), null); } public void attemptLogin() { mEmailView.setError(null); mPasswordView.setError(null); mEmail = mEmailView.getText().toString(); mPassword = mPasswordView.getText().toString(); boolean cancel = false; View focusView = null; if (TextUtils.isEmpty(mPassword)) { mPasswordView.setError(getString(R.string.error_field_required)); focusView = mPasswordView; cancel = true; } else if (mPassword.length() < 4) { mPasswordView.setError(getString(R.string.error_invalid_password)); focusView = mPasswordView; cancel = true; } if (TextUtils.isEmpty(mEmail)) { mEmailView.setError(getString(R.string.error_field_required)); focusView = mEmailView; cancel = true; } else if (!mEmail.contains("@")) { mEmailView.setError(getString(R.string.error_invalid_email)); focusView = mEmailView; cancel = true; } if (cancel) { focusView.requestFocus(); } else { mLoginStatusMessageView.setText(R.string.login_progress_signing_in); showProgress(true); gAuth = new GoogleAuthentication(ctx, mEmailView.getText().toString()); gAuth.setUserConfirmedListener(SettingsUnlockActivity.this); Bundle b = new Bundle(); b.putString(AccountManager.KEY_PASSWORD, mPasswordView.getText().toString()); try { gAuth.verifyAuth(b); } catch (IllegalArgumentException e) { doUnSuccessfulLogin(); } } }
