由于我将 Admob 库替换为 Google Play 服务库，我的 Android 应用有时会触发以下异常

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.XXX.XXX/com.XXX.XXX.ui.activity.FeedActivity}: java.lang.IllegalStateException: The ad size and ad unit ID must be set before loadAd is called.

基本上，例外是抱怨我没有在 loadAd 之前设置广告尺寸和单元 ID。这是我的代码：

    mAdView = new AdView(this);
    mAdView.setAdSize(AdSize.BANNER);
    mAdView.setAdUnitId(SourceActivity.APPLICATION_ADMOB_BANNER_ID);

    LinearLayout layout = (LinearLayout) findViewById(R.id.activity_view);
    layout.addView(mAdView);

    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
    mAdView.setVisibility(View.GONE);

    mAdView.setAdListener(new AdListener() {
      @Override
      public void onAdLoaded() {
          Log.d(TAG, "onAdLoaded");
          mAdView.setVisibility(View.VISIBLE);
      }
    });

如您所见，一切都是正确的。正如我之前所说，异常并不总是出现，实际上它只出现了几次。

有人知道是什么原因造成的吗？

修改代码

                  <com.google.android.gms.ads.AdView android:id="@+id/adView"
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     android:layout_below="@+id/gridView1"
                     ads:adUnitId="MY ID NUMBER"
                     ads:adSize="BANNER"/>

到

                 <com.google.android.gms.ads.AdView android:id="@+id/adView"
                     xmlns:ads="http://schemas.android.com/apk/res-auto"
                     android:layout_width="match_parent"
                     android:layout_height="wrap_content"
                     ads:adUnitId="ca-app-pub-8510605212168324/8634800090"
                     ads:adSize="BANNER"
                     android:layout_alignParentBottom="true"
                     >

                 </com.google.android.gms.ads.AdView>
