Cognito IDToken Renewal using RefreshToken

Question

Hi I am android application developer , I am using cognito authentication mechanism for mobile app. Once i authenticate my user i get RefreshToken and IDToken. According to Amazon cognito it expire IDToken after exactly one hour.I am trying to get my session again to get token again and here is how i am trying to get it done.

    String poolId       = 'xxxxxx';
    String clientId     = 'xxxxxx';
    String clientSecret = 'xxxxxx';

    CognitoUserPool userPool = new CognitoUserPool(context, poolId, clientId, clientSecret,Regions.EU_WEST_1);
    CognitoUser user = userPool.getUser();

    user.getSessionInBackground(new AuthenticationHandler() {

        @Override
        public void onSuccess(CognitoUserSession userSession, CognitoDevice newDevice) {
            String idToken = userSession.getIdToken().getJWTToken();

            Map<String, String> logins = new HashMap<String, String>();
            logins.put("cognito-idp." + Constants.REGION + ".amazonaws.com/" + Constants.UserPool, userSession.getIdToken().getJWTToken());

            credentialsProvider.setLogins(logins);
            credentialsProvider.refresh();
        }

        @Override
        public void getAuthenticationDetails(AuthenticationContinuation authenticationContinuation, String userId) {
            Log.i("MQTT","Detail");
        }

        @Override
        public void getMFACode(MultiFactorAuthenticationContinuation continuation) {
            Log.i("MQTT","MFACode");
        }

        @Override
        public void authenticationChallenge(ChallengeContinuation continuation) {
            Log.i("MQTT","Challenge");
        }

        @Override
        public void onFailure(Exception exception) {
            Log.i("MQTT","Fail");
        }
    });

I have userpoolid and need to know where from i can get clientID and clientSecret.So that i get data in onSuccess callback and get IDToken.

Really thankful if someone can help out. Thanks

Go to your user pool in cognito and click on the pool you want to work on.
Under general settings, click on app clients.
Now click on add app client.
Give your app a name
Make sure the Generate client secret is selected.
Click on create client app.

Now you can note down the client id and client secret.
