java - 不能用 proguard 缩水

Question

这是我的 proguard 配置（我从 android 工具文件夹中复制了它并添加了一些行）。

-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
-optimizationpasses 5
-allowaccessmodification
-dontpreverify
    
# The remainder of this file is identical to the non-optimized version
# of the Proguard configuration file (except that the other file has
# flags to turn off optimization).

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
    native <methods>;
}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**

我想在我的应用程序中使用 Flurry，但是当我尝试使用 FlurryAgen.jar 混淆我的应用程序时，proguard 无法说出很多这样的错误：

Warning: com.flurry.android.ay: can't find referenced class com.google.ads.AdListener

当我尽量不混淆来源时，proguard 也会失败。

如何在proguard中使用flurry？以及如何使 proguard 不混淆我的来源？

更新 我还提到 FlurryAgent.jar 似乎已经被混淆了 - http://korniltsev.ru/p/jBU0f1c.png。也许我们可以忽略缩小整个罐子？

Answer 1

最后我设法做到了这样：

-keep class com.flurry.** { *; }
-dontwarn com.flurry.**

Answer 2

Korniltsev 的回答对我有用，但是新的 flurry SDK (3.2.2) 建议添加以下内容：

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

可能存在一些需要新行的极端情况，所以我最终选择了他们的 README。

Answer 3

我不确定 Flurry 是如何专门与 AdListener 交互的，但 Google 类的名称是被混淆的。

尝试将该行添加-keep public class com.google.ads.AdListener到 proguard 文件中。如果 Flurry 使用其他 com.google.ads 类，您可能需要添加更多类例外，但该行应该可以解决您的即时警告。

更新： 问题是公共类方法名称被各种广告库混淆。因此，您可能需要包含额外的 proguard 设置以包含这些方法：

-keep public class com.google.ads.** { public protected *; } 
-keep public class com.inmobi.androidsdk.** { public protected *; }
-keep public class com.millenialmedia.android.** { public protected *; }
-keep public class com.mobclix.android.sdk.** { public protected *; }
-keep public class com.jumptap.adtag.** { public protected *; }

在与 Flurry 和 proguard 合作后，请务必在上传到您选择的应用市场之前彻底测试 apk。

Flurry（现在由 Yahoo 拥有）官方推荐的 proguard 文件可在此处获得：

https://developer.yahoo.com/flurry/docs/publisher/code/android/

-­keep class com.flurry.** { *; }
-­dontwarn com.flurry.**
-­keepattributes *Annotation*,EnclosingMethod,Signature
-­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.**

Flurry 不再需要您修改您的 proguard 配置，请参阅https://developer.yahoo.com/flurry/docs/integrateflurry/android/

注意：如果你添加了 Flurry 依赖的 AAR 格式，你不需要修改你的 AndroidManifest 文件或 ProGuard 配置。
