如何使用Proguard成功地使用Dagger 2.0混淆项目？

我很高兴看到谷歌的Dagger叉子已经上市.(在撰写本文时,我意识到它还没有"发布".)我们有一个使用匕首的Android应用程序,虽然我们没有使用许多更高级的功能.

我们有一个业务要求来混淆我们的代码,所以我已经尝试升级到Dagger 2.0-SNAPSHOT,希望从Dagger中删除运行时反射可以运行模糊处理..但是我发现反射是仍然用于在运行时用于加载类的字符串常量.

下面是我的proguard.conf的相关内容.

-dontpreverify
-keepattributes *Annotation*,JavascriptInterface,SourceFile,LineNumberTable,Signature
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-ignorewarnings

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.app.Fragment
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }

-keep public class * extends android.view.View {
    public (android.content.Context);
    public (android.content.Context, android.util.AttributeSet);
    public (android.content.Context, android.util.AttributeSet, int);
    public void set*(...);
}

-keepclasseswithmembernames class * {
    native ;
}

-keepclasseswithmembers class * {
    public (android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public (android.content.Context, android.util.AttributeSet, int);
}


###### dagger 2.0 stuff
-keep class dagger.** { *; }
-keep interface dagger.** { *; }
-keepnames class com.ourcompany.**

-keep class **$$ModuleAdapter { *; }
-keepnames class **$$InjectAdapter { *; }

-keepclassmembers class * {
    @javax.inject.Inject ;
    @javax.inject.Inject (...);
}
-adaptclassstrings

正如你所看到的,我已经关闭了很多混淆.这允许正确地注入一些类,但是在注入一个特定类时它仍然失败.

这是一个例外:

有没有人用谷歌的匕首叉尝试过proguard呢？
