MainActivity.java ( onCreate )

try {  

	//Change -> testapp ( realm name ) and base URL
    AuthorizationManager.config("KeyCloakAuthz", OAuth2AuthorizationConfiguration.class)  
            .setBaseURL(new URL("https://your-app-name.herokuapp.com/auth"))

    PipeManager.config("kc-upload", RestfulPipeConfiguration.class)  
                .module(AuthorizationManager.getModule("KeyCloakAuthz"))  
                .requestBuilder(new MultipartRequestBuilder());  
      
      authzModule = AuthorizationManager.getModule("KeyCloakAuthz");  
      
    } catch (MalformedURLException e) {  
        e.printStackTrace();  
    }

Let's create a button in MainActivity.xml and bind login method to click event.

    public void login(View view) {  
      
        authzModule.requestAccess(this, new Callback<String>() {  
            @Override  
		      public void onSuccess(String s) {  
	                //callback.onSuccess(s);  
		      Log.d(TAG, "Bearer Token :" + s);   
	      }  
      
              @Override  
	          public void onFailure(Exception e) {  
                if (!e.getMessage().matches(OAuthWebViewDialog.OAuthReceiver.DISMISS_ERROR)) {  
                    authzModule.deleteAccount();  
		      }  
            }  
        });  
    }
