Question

我正在建立一个安卓游戏。这是一个导出到Android Studio的Unity3D项目。我试图在Android Studio中管理所有Google Play服务（GPS）互动。这是负责与GPS交互的类（我知道我没有遵循标准的编程模式）：

package com.lemondo.eyescube;

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

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.games.Games;
import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;

public class GPSBinding implements ConnectionCallbacks, OnConnectionFailedListener {

    public GoogleApiClient googleApiClient;

    private static GPSBinding _gpsBindingInstance;
    public static GPSBinding instance(){
        if(_gpsBindingInstance == null){
            _gpsBindingInstance = new GPSBinding();
        }
        return _gpsBindingInstance;
    }

    public static void Initialize(){
        if(instance().googleApiClient == null) {
            instance().googleApiClient = new GoogleApiClient.Builder(UnityPlayer.currentActivity)
                    .addConnectionCallbacks(instance())
                    .addOnConnectionFailedListener(instance())
                    .addApi(Games.API)
                    .addScope(Games.SCOPE_GAMES)
                    .build();
        }
    }

    public static void AuthenticatePlayer() {
        Log.d("GPSBinding", "AuthenticatePlayer");
        try {
            if (instance().googleApiClient != null)
                instance().googleApiClient.connect();
            else
                Log.d("GPSBinding", "AuthenticatePlayer: googleApiClient is null");
        } catch (Exception e){
            e.printStackTrace();
        }
    }

    @Override
    public void onConnected(Bundle bundle) {
    }

    @Override
    public void onConnectionSuspended(int i) {
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
    }

}

这就是：应用程序启动，Unity在启动时调用 Initialize（）方法，等待1秒钟并调用 AuthenticatePlayer（）方法。

应用程序在 Authenticatelayer（）：

中的此行崩溃

instance().googleApiClient.connect();

我没有得到原因，这是堆栈跟踪：

关于SO的类似问题只是说调整Google Analytics，我完全不会使用它。奇怪的是它甚至没有例外 - 只是轰！崩溃！有谁知道什么可能是错的？提前谢谢！

Answer 1

愚蠢的愚蠢 - 我忘了在我的清单中添加app id：

<meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id" />

AndroidRuntime：关闭VM
