Question

我正在转换为Google Play服务下的新AdMob，我在图形界面上收到以下错误。我已多次清理该项目，但没有运气。有什么提示吗？

The following classes could not be instantiated: - com.google.android.gms.ads.AdView

Proguard的：

-keep class * extends java.util.ListResourceBundle {
  protected Object[][] getContents();
}

# Keep SafeParcelable value, needed for reflection. This is required to support backwards
# compatibility of some classes.
-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
  public static final *** NULL;
}

# Keep the names of classes/members we need for client functionality.
-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
  @com.google.android.gms.common.annotation.KeepName *;
}

# Needed for Parcelable/SafeParcelable Creators to not get stripped
-keepnames class * implements android.os.Parcelable {
   public static final ** CREATOR;
}

根据这个Link，似乎需要java代码，你需要将它添加到你的onCreate：

AdView adView = (AdView)this.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("TEST_DEVICE_ID")
.build();
adView.loadAd(adRequest);

同时将其添加到您的布局广告视图：

<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
....

Android / Eclipse：无法实例化以下类： - com.google.android.gms.ads.AdView
