noclassdeffounderror com.google.android.gms.ads.AdView

Question

我已经完成了Google Play服务迁移教程https://developers.google.com/mobile-ads-sdk/docs/admob/play-migration

一切正常，但是当我创建 Adview 时，它就完成了。

这是我的代码：

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

    private AdView adView;
   RelativeLayout layoutPublicidadHueco;

   .
   .
   .

    layoutPublicidadHueco = (RelativeLayout) findViewById(R.id.layoutAdver);
    AdView adView = new AdView(this);
    adView.setAdUnitId("my number");
    adView.setAdSize(AdSize.SMART_BANNER);

    adView.setAdListener(new AdListener() {
        public void onAdLoaded() {}
        public void onAdFailedToLoad(int errorcode) {}
            // Only implement methods you need.
        });
    layoutPublicidadHueco.removeAllViews();
    layoutPublicidadHueco.addView(adView);
    layoutPublicidadHueco.setVisibility(View.VISIBLE);
    AdRequest request = new AdRequest.Builder().build();
    adView.loadAd(request);

提前致谢。

我解决了，我在库中添加了谷歌播放服务，我在外部 jar 中添加了谷歌播放服务，我已经导出了它。

谢谢
