Using ProGuard with Android
提问by flawyte
I have problems dealing with ProGuard and Android.
我在处理 ProGuard 和 Android 时遇到问题。
I searched on the web for hours and found multiple ways to obsfuscate an Android application. For now I'm trying one that looks to be the easiest, so :
我在网上搜索了几个小时，发现了多种混淆 Android 应用程序的方法。现在我正在尝试一种看起来最简单的方法，所以：
- I created a
config.cfgfile in the root directory of my project- I added
proguard.config=config.cfgin myproject.properties- The I used the Eclipse export wizard to export & sign the .apk file
- 我在
config.cfg我的项目的根目录中创建了一个文件- 我
proguard.config=config.cfg在我的project.properties- 我使用 Eclipse 导出向导来导出和签署 .apk 文件
I got a message saying Proguard returned with error code 1. See consoleand in the console:
我Proguard returned with error code 1. See console在控制台中收到一条消息：
Proguard returned with error code 1. See console
Note: there were 3847 duplicate class definitions.

You should check if you need to specify additional program jars.
Warning: there were 4 unresolved references to classes or interfaces.
You may need to specify additional library jars (using '-libraryjars').
Error: Please correct the above warnings first.
Even if I use the config provided by the official Proguard website, or the default one I have errors.
Here is my custom config (myProject/config.cfg):
即使我使用 Proguard 官方网站提供的配置，或者默认配置我也有错误。
这是我的自定义配置 (myProject/config.cfg)：
-injars bin/classes
-injars libs
-libraryjars "C:\Program Files\Android\android-sdk\platforms\android-13\android.jar"
-dontskipnonpubliclibraryclasses
-optimizationpasses 5
-printmapping map.txt
-flattenpackagehierarchy
-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations !code/simplification/arithmetic
-keepattributes *Annotation*
-keep public class * extends android.app.Application
-keep public class * extends android.app.Activity
-keep public class * extends android.app.PreferenceActivity
-keep public class * extends android.view.View
-keep public class * extends android.widget.BaseAdapter
-keep public class * implements android.view.View.OnTouchListener
-keep public class * extends android.view.View {
public <init>(android.content.Context);
public <init>(android.content.Context, android.util.AttributeSet);
public <init>(android.content.Context, android.util.AttributeSet, int);
public void set*(...);
}
-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers class * extends android.content.Context {
public void *(android.view.View);
public void *(android.view.MenuItem);
}
-keepclassmembers class * implements android.os.Parcelable {
static android.os.Parcelable$Creator CREATOR;
}
-keepclassmembers class **.R$* {
public static <fields>;
}
I can't get it to work... any idea would be greatly appreciated !
NOTE :I use the Hymanson JSON librairies that are stored in the libsfolder of my project
我无法让它工作......任何想法将不胜感激！
注意：我使用存储在libs我的项目文件夹中的 Hymanson JSON 库

The Android Ant/Eclipse builds already specify -injars/-libraryjars for you. If you specify them again in your configuration, ProGuard notes that they are duplicated. So don't specify -injars/-libraryjars.
Android Ant/Eclipse 构建已经为您指定了 -injars/-libraryjars。如果您在配置中再次指定它们，ProGuard 会注意到它们是重复的。所以不要指定-injars/-libraryjars。

org.w3c.dom.bootstrap.DOMImplementationRegistry is not present in the input code, yet com.fasterxml.Hymanson.databind.ext.DOMSerializer is using it. If your application works anyway, you can let ProGuard accept it with:
org.w3c.dom.bootstrap.DOMImplementationRegistry 不存在于输入代码中，但 com.fasterxml.Hymanson.databind.ext.DOMSerializer 正在使用它。如果您的应用程序仍然有效，您可以让 ProGuard 接受它：
-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry

I just got stuck with the same problem, and I solved it by referencing the JRE rt.jar file:
我刚遇到同样的问题，我通过引用 JRE rt.jar 文件解决了它：
-libraryjars /lib/rt.jar
