无法使用 ProGuard 获取广告、Flurry 5.3

Question

我的应用程序无法在 google 中发布 ProGuard 时获得 flurry 广告。如果我运行没有 ProGuard 的应用程序一切正常。我启用日志和 flurry SDK 写入下一条信息：

02-20 16:31:09.765    8953-8953/? D/FlurryAdServingApp﹕ fetchAndDisplay: Banner

我不明白他为什么写未知来源如果在 proguard-project.txt 我接下来写：

-keep class com.flurry.** { *; }
-dontwarn com.flurry.**
-keepattributes *Annotation*,EnclosingMethod
-keepclasseswithmembers class * {
  public <init>(android.content.Context, android.util.AttributeSet, int);
}

# Google Play Services library
-keep class * extends java.util.ListResourceBundle {
  protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
  public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
  public static final ** CREATOR;
}
#If you are using the Google Mobile Ads SDK, add the following:
# Preserve GMS ads classes
-keep class com.google.android.gms.ads.** { *;
}
-dontwarn com.google.android.gms.ads.**


#If you are using the InMobi SDK, add the following:
# Preserve InMobi Ads classes
-keep class com.inmobi.** { *;
}
-dontwarn com.inmobi.**
#If you are using the Millennial Media SDK, add the following:
# Preserve Millennial Ads classes
-keep class com.millennialmedia.** { *;
}
-dontwarn com.millennialmedia.**

请帮帮我。

我有完全相同的错误消息，"W/System.err﹕ java.lang.ClassCastException: com.flurry.sdk.it cannot be cast to com.flurry.android.impl.ads.protocol.v13.AdUnit"。

我联系了 Flurry 支持，support@flurry.com，2 个工作日后（今天），他们回答说：

Thank you for contacting Flurry support. In your proguard config, could you please change the 3rd line from:
-keepattributes *Annotation*,EnclosingMethod
to
-keepattributes *Annotation*,EnclosingMethod,Signature
Note the addition of "Signature". Please try this new configuration and let us know if it works.

我对 Proguard 进行了调整，Flurry 广告现在似乎可以正常工作了。总结一下，我的 Flurry Proguard 配置如下：

#Flurry
-keep class com.flurry.** { *; }
-dontwarn com.flurry.**
-keepattributes *Annotation*,EnclosingMethod,Signature
-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}
# Preserve Flurry mediation classes for DFP/AdMob Ads
-keep public class com.google.ads.mediation.flurry.**

作为参考，我使用的是 FlurryAds-5.3.0.jar、FlurryAnalytics-5.3.0.jar 和 flurryAndroidDFPandAdMobMediationAdapter-5.0.0.r1.jar
