Request for Auth.getPreferredMFA(...) for JavaScript parity

[saravhari]

AWS Cognito Android SDK "GET MFA API" (getUserMfaSettingsInBackground) needed from CognitoUserPool class

Need to get the current user MFA setting as an API

In Amplify JavaScript library this get method is available.

But in Android sdk only option available is "setUserMfaSettingsInBackground".

public void setUserMfaSettingsInBackground(final List<CognitoMfaSettings> mfaSettings,
                                            final GenericHandler callback) {
        if (callback == null) {
            throw new CognitoParameterInvalidException("callback is null");
        }
        final CognitoUserSession session = this.getCachedSession();

        new Thread(new Runnable() {
            @Override
            public void run() {
                final Handler handler = new Handler(context.getMainLooper());
                Runnable returnCallback;
                try {
                    setUserMfaSettingsInternal(mfaSettings, session);
                    returnCallback = new Runnable() {
                        @Override
                        public void run() {
                            callback.onSuccess();
                        }
                    };
                } catch (final Exception e) {
                    returnCallback = new Runnable() {
                        @Override
                        public void run() {
                            callback.onFailure(e);
                        }
                    };
                }
                handler.post(returnCallback);
            }
        }).start();
    }

We want to perform the SMS_MFA enable and disable provision in mobile as well as web app. I'm able to update the preferred MFA type in web and can able to get the current state on load. Same thing need to be done on android, While landing to a screen initially I need to check the current Preferred MFA type and then I will update the type.

Kindly help on this to get the get API in android SDK.

Thanks for suggesting this - we will keep it in mind here and prioritize it based on demand.

For reference, Amplify JS reads this value from some local settings. The Set* call, though, is a Cognito service API call.

The SetUserMfaPreference is a Cognito service API.

Amplify Android v2 now has the capability to fetch current MFA preferences, in addition to updating preferences!
