我正在尝试在我的应用上设置Google Play服务广告。但是每当我尝试拨打电话时
adView.loadAd()
它崩溃了应用程序。如果我注释掉这一行，广告不会崩溃，但窗口不会显示。我已经尝试过关于这个主题的类似问题，但找不到适用于我的解决方案。任何帮助将不胜感激。
这是我的主要内容：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Look up the AdView as a resource and load a request.
AdView adView = (AdView)this.findViewById(R.id.adView1);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest); // this is what seems to be causing the problem
