android - Libgdx game with Google play game services in android app问题

Question

我一直在询问有关我的 Libgdx 游戏 Google Play 游戏服务配置错误的问题。到目前为止，我已经解决了登录错误，但现在我被困在解锁成就上。所以我发布我的代码可能有人可以帮助我。

这是我在 Core Libgdx 项目中创建的 ActionResolver 接口(interface)

  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() ;
    }

我的 AndroidLauncher 类是

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

import android.widget.Toast;

    }

}

这个值为 100 的 score int 我只是想测试它是否有助于解锁成就。

我在 Core 项目中的 MainGame 类是

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

import com.badlogic.gdx.Application.ApplicationType;
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();
    }

}

我的 Android list 文件是

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.--------.game.android"
    android:versionCode="2"

            android:configChanges="keyboard|keyboardHidden|orientation|screenSize">

            </intent-filter>
        </activity>



    </application>

</manifest>

我在 Android/Res 文件夹中的字符串文件有这个

<?xml version="1.0" encoding="utf-8"?>
<resources>

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

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

当我在 Debug模式下运行我的应用程序时，我的 Logcat 会这样说(注意:我已经在开发者控制台上配置了 Google Play 游戏服务|我的游戏已经在第一版没有游戏服务的情况下发布，所以为了测试游戏服务我已经发布了我的游戏服务在Alpha，我已经成功添加测试人员，我可以用测试账号登录，我也有Dubug和发布证书Client ID)

现在我不明白了。当我成功连接时，为什么我不能在游戏服务中做任何其他事情。我只有在特定分数上需要解锁的成就。

使用所有 LIBGDX 游戏教程，Google Type a number 和 trival exmaple and tutorial 我现在感到绝望，因为我根本无法配置这些游戏服务。

我也在游戏结束时从 gamescreen 类发送我的分数，但现在删除了它，因为它只是在登录时生成空指针异常(到谷歌游戏服务)。我也可以发布该代码

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



        }


    } 

请成功完成此操作的任何人。帮帮我。

查看启动器类中的 loginGPGS() 方法...您可以成功连接，因为 loginGPGS 在 ui 线程上运行...尝试在 ui 线程上访问 GPGS，因为它需要在您的主要 Activity 的上下文....这就是我访问我的方式:

@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) {
    }

}
