使用Android proguard忽略外部庫

Question

我想使用Proguard主要用於混淆原因。

我在Android中遇到了proguard問題。我使用simpleframework來解析XML;它的外部。

在proguard的CFG：

-keepattributes *Annotation*,EnclosingMethod  
    -keep public class org.simpleframework.**{ *; } 
    -keep public class org.simpleframework.xml.**{ *; } 
    -keep public class org.simpleframework.xml.core.**{ *; } 
    -keep public class org.simpleframework.xml.util.**{ *; } 
    -keep public class org.simpleframework.xml.stream.**{ *; } 
    -keep public class javax.** { *; } 
    -keep public class javax.xml.stream.**{ *; } 

    -keep public class org.simpleframework.** { 
     public void set*(***); 
     public *** get*(); 
    } 

錯誤：

我不知道如何解決這個問題。 gradle cfg的路徑確定。

在gradle這個

：

buildTypes { 
     release { 
      runProguard true 
      proguardFile file('proguard.txt') 
      signingConfig signingConfigs.release 
     } 
    }

這proguard的配置來幫助我Proguard obfuscation is breaking simplexml

# The following line may be different 
-libraryjars <java.home>/lib/rt.jar(java/**,javax/**) 

-optimizationpasses 5 
-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-dontpreverify 
-verbose 
# (3)Not remove unused code 
-dontshrink

-keepclassmembers class * extends android.app.Activity {

} 

-keepclassmembers enum * { 
    public static **[] values(); 
    public static ** valueOf(java.lang.String); 
} 

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

這些都不是在輸出中，你可以跳過錯誤，但警告：

-dontwarn org.simpleframework.xml.stream.** 

或在一般情況下：

-dontwarn 

---

P.S.跳過後，我得到

Value is not a reference value [proguard.evaluation.value.InstructionOffsetValue]

它被固定adding next line到ProGuard的

-optimizations !class/unboxing/enum 

Answer 3

感謝eXistPierre後，這是我需要得到它的工作的最小值：

-libraryjars <java.home>/lib/rt.jar(java/**,javax/**) 
-keep public class org.simpleframework.**{ *; } 
-keep class org.simpleframework.xml.**{ *; } 
-keep class org.simpleframework.xml.core.**{ *; } 
-keep class org.simpleframework.xml.util.**{ *; } 
-keepattributes *Annotation* 
-keepattributes Signature 

我也需要添加以下內容，以便我可以讀寫我的類對象：

-keepclassmembers class com.package.app.ClassItem{ *; }
