[aerogear-dev] oAuth with Keycloak OpenId in Android Client

Hi, I want to authenticate a user (using his username and password) in an Android App using aerogear with a server using Keycloak. I haven't been able to do it, help me please. I currently can authenticate the user without aerogear, but I want to use this library since it can help me to refresh the token when is needed. I authenticate the user making a POST call to the server like this (but from android): curl -X POST http://127.0.0.1:8080/auth/realms/example/protocol/openid-connect/token -H "Content-Type: application/x-www-form-urlencoded" -d "username=auser" -d 'password=apassword' -d 'grant_type=password' -d 'client_id=clientId' -d 'client_secret=secret' What I have tried with Aerogear is this: private void authz() { try { AuthzModule authzModule = AuthorizationManager.config("KeyCloakAuthz", OAuth2AuthorizationConfiguration.class) .setBaseURL(new URL("http://127.0.0.1:8080/")) .setAuthzEndpoint("/realms/example/protocol/openid-connect/auth") .setAccessTokenEndpoint("/realms/example/protocol/openid-connect/token") .setAccountId("keycloak-token") .setClientId("clientId") .setClientSecret("secret") .setRedirectURL("http://oauth2callback") .setScopes(Arrays.asList("openid")) .addAdditionalAuthorizationParam((Pair.create("grant_type", "password"))) .addAdditionalAuthorizationParam((Pair.create("username", "aUserName"))) .addAdditionalAuthorizationParam((Pair.create("password", "aPassword"))) .asModule(); authzModule.requestAccess(this, new Callback<String>() { @Override public void onSuccess(String o) { Log.d("TOKEN ", o); } @Override public void onFailure(Exception e) { System.err.println("Error!!"); Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show(); } }); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException(e); }} However this doesn't do anything. What I don't understand is: 1. How can I specify that I'm doing and OpenID Connect with Keycloak in Aerogear(Android) ? I've seen it in the swift library but I cannot find it in Android 2. How and where can I send the username and password? 3. How can I specify the grant_type? (My HTTP POST to the server does not work if I don't include this, so it's important) I'm really sorry if this is a very basic question, but I haven't been able to work it out on my own. Any help or documentation would be appreciated.
