Android Cocos2d Firebase Admob崩溃

我安装了Firebase，完成了整个设置，但当我在android上加载我的应用程序时，会显示“很遗憾，（应用程序）已停止”。该应用程序只是默认的Cocos HelloWorld场景。我使用的是cocos2dx 3.15.1、Visual Studio 2013、Android NDK r10e和SDK版本26.0.1

我的应用程序实际上是默认项目，只是添加了Firebase教程中的所有内容，它崩溃了。我已经安装了firebase_cpp文件，firebaseheloper头和源代码与教程中的完全相同，而Cocos2d应用程序中的所有其他内容，至少我认为，都是默认设置。我该怎么办？可能是什么

当我在Android Studio中运行应用程序时，它会显示错误：

E/firebase:无法检查Google Play服务的可用性，因为此应用程序中不存在com.Google.Android.gms.common.GoogleAppAvailability类。

我认为Google Play服务不可用。您可以通过以下方法进行检查：-

/** *用于检查google play服务是否可用 *@param上下文 *@返回 */

---

我应该把它放在什么代码文件中，如果它可用或不可用，我该怎么办？实际上，我认为在进行firebase集成之前，您需要安装play service。否则，您应该向用户显示某种弹出窗口。您还应该在安装了GPS的设备上运行此代码。

public boolean isGooglePlayServicesAvailable(Context context) {
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    int resultCode = googleApiAvailability.isGooglePlayServicesAvailable(context);
    return resultCode == ConnectionResult.SUCCESS;
}
