VKSDK not displaying query result?

Question

Java

Everything seems to be connected correctly.
I make any request from the documentation and try to display System.out.println(response.toString())
gives something like - [email protected]
authorization in the application passes. in any case, a window appears with the permission of the rights and after clicking on the "allow" button disappears.
in gredel added - 'compile 'com.vk:androidsdk:1.6.5'
to the manifest - and a line in application - android:name=".Application"
QUESTION: why is a request like *[email protected] 534ea208 instead of information from VK?
below is the whole code...

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

import com.vk.sdk.VKAccessToken;
import com.vk.sdk.VKCallback;

public class MainActivity extends Activity {

    private String log = "Log - ";
    private String[] scope = new String[]{VKScope.MESSAGES, VKScope.FRIENDS, VKScope.WALL};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        VKSdk.login(this, scope);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (!VKSdk.onActivityResult(requestCode, resultCode, data, new VKCallback<VKAccessToken>() {
            @Override
            public void onResult(VKAccessToken res) {
                Log.d(log , " Oki");
                VKRequest request = new VKApiGroups().getById(VKParameters.from("group_ids","club147546053"));
                request.executeWithListener(new VKRequest.VKRequestListener() {
                    @Override
                    public void onComplete(VKResponse response) {
                        super.onComplete(response);
                        System.out.println(response.toString());
                    }
                });
            }

            @Override
            public void onError(VKError error) {
                Log.d(log, "error");
            }
        })){
            super.onActivityResult(requestCode, resultCode, data);
        }
    }
}

import android.content.Intent;
import android.support.annotation.Nullable;

import com.vk.sdk.VKAccessToken;
import com.vk.sdk.VKAccessTokenTracker;
import com.vk.sdk.VKSdk;

public class Application extends android.app.Application {

    VKAccessTokenTracker vkAccessTokenTracker = new VKAccessTokenTracker() {
        @Override
        public void onVKAccessTokenChanged(@Nullable VKAccessToken oldToken, @Nullable VKAccessToken newToken) {
            if (newToken == null){
                Intent intent = new Intent(Application.this, MainActivity.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(intent);
            }
        }
    };

    @Override
    public void onCreate() {
        super.onCreate();
        vkAccessTokenTracker.startTracking();
        VKSdk.initialize(this);
    }
}

Answer 1

Because this class does not override the toString method. See the documentation for what meaningful methods this class has, call them.
