Libgdx game with Google play game services in android app problems

Question

I have been asking questions related to my Libgdx game Google play game services configuration error. Up-till now I have solved sign in errors but Now I am stuck at Unlock Achievements. So I am posting my code may Be some one can help me out then.

Here Is my ActionResolver Interface That I created In Core Libgdx project

  package com.------.game;

    public interface ActionResolver {
    public boolean getSignedInGPGS();
    public void loginGPGS();
    public void submitScoreGPGS(int score);
    public void unlockAchievementGPGS(String achievementId);
    public void getLeaderboardGPGS();
    public void getAchievementsGPGS();
    public void onShowAchievementsRequested() ;
    }

My AndroidLauncher class is

 package com.------.game.android;

This score int that has a value of 100 I just tried to test if it helps to unlock achievement.

My MainGame class in Core project is

   package com.----------.game;

import com.badlogic.gdx.Game;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

import com.-------.helpers.AssetLoader;

import com.------.screens.FirstSplash;

public class MainGame extends Game {

    SpriteBatch batch;
    Texture img;
    public ActionResolver actionResolver;

    Game game;


    public MainGame(ActionResolver actionresolver) {

        this.actionResolver = actionresolver;

    }

    @Override
    public void create() {

        Gdx.app.log("Game", "created");
        AssetLoader.load();

        setScreen(new FirstSplash(this));

    }

    public void show() {
        Gdx.app.log("my Splash Screen", "show called");


        if (Gdx.app.getType() == ApplicationType.Android) {
            actionResolver.getSignedInGPGS();

             actionResolver.submitScoreGPGS(110);

             actionResolver.unlockAchievementGPGS("ABC-----");



        } else {
            actionResolver.loginGPGS();
        }

    }

    @Override
    public void dispose() {

        super.dispose();
        AssetLoader.dispose();
    }

}

My Android Manifest File is

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

My Strings File in Android/Res folder has this

<resources>

    <string name="app_name">My Game</string>

    <string name="app_id">------------</string> // has my app id
</resources>

My Logcat says this when I run my app in Debug Mode(Note: I have already configured Google play game services on Developer console| My game is already published without Game services in First Version so to test Game services I have published my Game services in Alpha. I have successfully added testers. I am able to sign in with test account. I also have Dubug plus release certificates Client ID)

03-11 10:28:49.823: I/my Spash Screen(16750): constructor called
03-11 10:28:49.829: I/my Splash Screen(16750): hide called

03-11 10:28:57.361: I/GameScreen(16750): resizing

Now I dont get it. when I am SUCCESSFULLY CONNECTED why i cant do anything else in game services. I just have achievements that I need to unlock on a particular score.

Using all LIBGDX game tutorials, Google Type a number and trival exmaple and tutorial I feel hopeless now that I cant configure these game services at all.

I was also sending my scores at game over from gamescreen class but removed it now because it simply generate Null pointer exception on Sign in(to google game services). I can post that code as well

if (Gameover ----) {



        if ((game.actionResolver.getSignedInGPGS())) { // My app crashes at this point ton check Sign in by giving Null pointer exception
            game.actionResolver.submitScoreGPGS(AssetLoader.getScore);
        if (AssetLoader.getScore >= 2500) game.actionResolver.unlockAchievementGPGS("-----"); // my id is here



        }


    } 

KINDLY ANYBODY WHO HAS DONE THIS SUCCESSFULLY. hELP ME OUT.

Answer 1

Take a look at your loginGPGS() method in your launcher class...You can successfully connect because loginGPGS is run on the ui thread....Try accessing GPGS on the ui thread because it needs to be run in the context of your Main activity....This is how I access mine:

@Override
public void getLeaderboardGPGS() {

    try {
        runOnUiThread(new Runnable() {
            public void run() {
                if (gameHelper.isSignedIn()) {
                    startActivityForResult(
                            Games.Leaderboards.getLeaderboardIntent(
                                    gameHelper.getApiClient(),
                                    "XXXXXXXXXX-XXX-XXX"), 100);
                } else if (!gameHelper.isConnecting()) {
                    loginGPGS();
                }
            }
        });
    } catch (final Exception ex) {
    }

}


@Override
public void sendScoreGPGS() {

    try {
        runOnUiThread(new Runnable() {
            public void run() {
                if (gameHelper.isSignedIn()) {
                    startActivityForResult(
                            Games.Leaderboards.submitScore(gameHelper.getApiClient(),
            "YOUR-GPGS-HASH", score);
                } else if (!gameHelper.isConnecting()) {
                    loginGPGS();
                }
            }
        });
    } catch (final Exception ex) {
    }

}
