Question

我创建了一个只有广告的空白应用，并在加载时强制关闭。继承人我做了什么：

将google-play-services库添加到项目中插入元数据标记插入权限标记插入活动标签在片段xml中插入xmlns行和com.google标记将com.google导入到主java中将adview代码添加到主java中救了它。

没有错误，图形显示屏显示一个框，其中显示了＃go;＆＃34; google＆＃34;但不显示广告。当我尝试在模拟器中运行它时，应用程序强制关闭。我错过了什么？谢谢你们！

        @Override

            View rootView = inflater.inflate(R.layout.fragment_main, container, false);
            return rootView;
        }
    }

}

好的，谢谢链接工作，我看了代码我已编辑您的问题以包含代码。你可以这样试试吗：
而不是简单地导入import com.google.android.gms.ads.*;
尝试使用：

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);   
 adView = new AdView(this); //I couldn't see this line in your code. It goes under the line setContentView(R.layout.activity_main);
    AdView adView = (AdView) this.findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder()
    .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
    .build();
    adView.loadAd(adRequest);

让我知道会发生什么。另外，您如何在XML中设置广告？

我没有错误，广告不会显示（强制关闭）
