ProGuard - 应用程序在模拟器中工作正常，但在尝试构建apk时失败

标签： java android proguard android-proguard

我正在尝试发布我的应用程序，但我需要对apk进行混淆+我想削减一些大小。我也不需要对apk进行签名，因此调试版本可以实现。

我正在使用一些库：

  • Guava 22.0
  • Okhttp 3.8.1
  • SimpleXML 2.7。+
  • EventBus 3.0
  • Apache Common Codec 1.10

我在apk版本中获得的错误：

Warning:com.google.common.util.concurrent.FuturesGetChecked$GetCheckedTypeValidatorHolder$ClassValueValidator$1: can't find superclass or interface java.lang.ClassValue
Warning:com.google.common.util.concurrent.FuturesGetChecked$GetCheckedTypeValidatorHolder$ClassValueValidator: can't find referenced class java.lang.ClassValue
Warning:com.google.common.util.concurrent.FuturesGetChecked$GetCheckedTypeValidatorHolder$ClassValueValidator$1: can't find referenced class java.lang.ClassValue
Warning:there were 8 unresolved references to classes or interfaces.
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForDebug'.
> Job failed, see logs for details

目前的规则：

的build.gradle：

}

}


configurations.all {
    resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
}

放-dontwarn javax.xml.stream.events.**会将警告降低到86，但我不确定如何解决其余问题。

此外，行"Execution failed for task ':app:transformClassesAndResourcesWithProguardForDebug'.是因为警告而出现此错误，还是完全不同？

我真的很感激你的帮助！

欢呼声

更新：将警告减少到仅8，更新了我的程序规则以及警告

Update2：摆脱了所有的警告，但是apk根本没有混淆，我可以用apktool / dex2jar反编译它，看看发生了什么。

这里的proguard规则可以帮助你：

# EventBus 3.0 rules
# http://greenrobot.org/eventbus/documentation/proguard/
-keepattributes *Annotation*
-keepclassmembers class ** {
    @org.greenrobot.eventbus.Subscribe <methods>;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }

# Only required if you use AsyncExecutor
-keepclassmembers class * extends org.greenrobot.eventbus.util.ThrowableFailureEvent {
    <init>(java.lang.Throwable);
}

# SimpleXML proguard
# Keep public classes and methods.
-dontwarn com.bea.xml.stream.**
-dontwarn org.simpleframework.xml.stream.**
-keep class org.simpleframework.xml.**{ *; }
-keepclassmembers,allowobfuscation class * {
    @org.simpleframework.xml.* <fields>;
    @org.simpleframework.xml.* <init>(...);
}

#okhttp3 rules, https://github.com/square/okhttp#proguard
-dontwarn okio.**
-dontwarn javax.annotation.Nullable
-dontwarn javax.annotation.ParametersAreNonnullByDefault

对于old version of Guava：

# Configuration for Guava 18.0
#
# disagrees with instructions provided by Guava project: https://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava

-keep class com.google.common.io.Resources {
    public static <methods>;
}
-keep class com.google.common.collect.Lists {
    public static ** reverse(**);
}
-keep class com.google.common.base.Charsets {
    public static <fields>;
}

-keep class com.google.common.base.Joiner {
    public static com.google.common.base.Joiner on(java.lang.String);
    public ** join(...);
}

-keep class com.google.common.collect.MapMakerInternalMap$ReferenceEntry
-keep class com.google.common.cache.LocalCache$ReferenceEntry

# http://stackoverflow.com/questions/9120338/proguard-configuration-for-guava-with-obfuscation-and-optimization
-dontwarn javax.annotation.**
-dontwarn javax.inject.**
-dontwarn sun.misc.Unsafe

# Guava 19.0
-dontwarn java.lang.ClassValue
-dontwarn com.google.j2objc.annotations.Weak
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

我刚刚遇到了与您相同的错误，我通过为java.lang添加直接dontwar来解决了这个问题：

-dontwarn java.lang.**

它从8条警告变为0条，并纠正了APK的构建。
