AdMob 横幅在启用 ProGuard 时为空白 [英] AdMob banner is blank with ProGuard enabled

问题描述

I've added the AdMob (320x50 banners) to my project and tested it successfully in debug mode. For production builds I have ProGuard obfuscation enabled and banners disappeared. I've tried using these ProGuard rules but it doesn't affect:

-keep public class com.google.android.gms.ads.** {
   public *;
}

-keep public class com.google.ads.** {
   public *;
}

I initialize AdMob in my Application class like:

MobileAds.initialize(getApplicationContext(), getString(R.string.banner_ad_id));

in xml layout I place banner:

<com.google.android.gms.ads.AdView
        xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/adView"
        android:layout_width="match_parent"
        android:visibility="gone"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_ad_unit_id">
</com.google.android.gms.ads.AdView>

after, I load a banner this way:

AdView adMobView = (AdView) bannerLayout.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adMobView.loadAd(adRequest);

Also, I'm using second ad provider (adtech) and play with their visibility depending on conditions. Any idea how to make them visible?

解决方案

Finally, I've found where was my problem - I shouldn't had set AdView's initial visibility parameter to GONE. Even through I've changed it programmatically to VISIBLE - it did not work in signed apk (still a mystery).
