问题描述
我是新来使用Proguard的，所以我可能会做一个新手的错误。我有一个应用程序，当我运行发布版本（使用Proguard的混淆），它很快崩溃pretty的。我相信我已经收窄，到现在看来似乎是混淆我的参考图书馆的事实。在我的情况下我的参考库用于定义我使用的通信使用谷歌Protobuffers其他设备我的邮件类。我建立使用，蚂蚁释放。 我ProGuard的配置是：
I'm new to using Proguard so I'm probably making a newbie mistake. I've got an app that after I run the release build (which uses Proguard to obfuscate) it crashes pretty quickly. I believe I've narrowed it down to the fact that it seems like it is obfuscating my reference libraries. In my case my reference libraries are used to define my message classes that I am using to communicate to another device using Google Protobuffers. I am building using, ant release. My proguard config is:
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-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.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 public class com.android.vending.licensing.ILicensingService
-keepclasseswithmembernames class *
{
native <methods>;
}
-keepclasseswithmembernames class *
{
public <init>(android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembernames class *
{
public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers enum *
{
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable
{
public static final android.os.Parcelable$Creator *;
}
在我的Ant build.xml文件我有以下定义：
In my ant build.xml file I have the following defined:
<target name="-obfuscate" unless="do.not.compile">
<if condition="${proguard.enabled}">
<then>
<property name="obfuscate.absolute.dir" location="${out.absolute.dir}/proguard" />

我倒是AP preciate任何想法。我复制在大多数的在线模板我的构建和ProGuard的配置，我怀疑我其实intructing Proguard的混淆图书馆罐子或者我有什么lisconfigured。 我看到在我的cmd窗口下面的输出生成的末尾：
I'd appreciate any ideas. I copied in most of my build and proguard config from online templates, I suspect that I am actually intructing Proguard to obfuscate the library jars or I have something lisconfigured. I am seeing the following output in my cmd window at the end of the build:
[proguard] Writing output...
[proguard] Preparing output jar [C:\Workspace\UI\MyApp\build\proguard\obfuscated.jar]
[proguard] Copying resources from program jar [C:\Workspace\UI\MyApp\build\proguard\original.jar]

谢谢！
推荐答案
您已经在Proguard的配置您的评论库JAR指令。
变化：
You have commented your library jar directives in the Proguard config.
Change:
# -libraryjars /libs/protobuf-2.3.0.jar
# -libraryjars /libs/libmessaging.jar
到
-libraryjars /libs/protobuf-2.3.0.jar
-libraryjars /libs/libmessaging.jar
（然后不打扰定义你的build.xml文件库中的罐子）
(and then don't bother defining your library jars in your build.xml)
编辑：
我发现了另一个方法，使Proguard的假库罐独显问到preserve自己的包名，例如：
I found another way to make Proguard leave library jars alone was to ask it to preserve their package names, eg:
-keep class javax.** { *; }
-keep class org.** { *; }
-keep class twitter4j.** { *; }
