从Android proguard中排除Java SE库

Question

在Android中,我有以下设置的proguard.

-dontpreverify

# Hold onto the mapping.text file, it can be used to unobfuscate stack traces in the developer console using the retrace tool
-printmapping mapping.txt

# Keep line numbers so they appear in the stack trace of the develeper console
-keepattributes SourceFile,LineNumberTable 

# The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle.
-optimizations !code/simplification/arithmetic 

# Activities, services and broadcast receivers are specified in the manifest file so they won't be automatically included
-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 

# Custom view components might be accessed from your layout files
-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*(...);
}

# event handlers can be specified in the layout files e.g. android:onClick="nextButton_onClick", I borrowed this method name notation from .NET
-keepclassmembers class * extends android.app.Activity {
    public void *_*(android.view.View);
}

# Parcelable implementations are accessed by introspection
-keepclassmembers class * implements android.os.Parcelable {
    static android.os.Parcelable$Creator CREATOR;
}

# You might want to keep your annotations
-keepattributes *Annotation*

# I use Google Guava in my app
# see http://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava
-libraryjars libs/google/jsr305-1.3.9.jar;libs/pinyin4j/pinyin4j-2.5.0.jar
-dontwarn sun.misc.Unsafe

-keepclasseswithmembers class com.google.common.base.internal.Finalizer{
    <methods>;
}

我的一些库直接从Java SE导入(例如包含JApplet)

我怎样才能将他们从proguard中排除？注意,我有pinyin4j-2.5.0.jar图书馆-libraryjars.我认为这是告诉proguard的方式,"嘿,这是一个图书馆.不要做任何事情,好吗？" 但是,似乎proguard仍在尝试处理pinyin4j-2.5.0.jar

我收到以下错误.

有些人可能会评论说,对于包含Java SE的库jar,只有方法(如Applet,Swing,...)不能在Android中使用.不.实际上,只要您使用非Java SE-only方法,它们就可以完美运行.

Answer 1

如果您确定不使用这些Java SE类,您确实可以忽略警告(正如您在自己的答案中找到的那样).一种更简单的方法来指定:

-dontwarn java.beans.**
-dontwarn java.awt.**
-dontwarn javax.swing.**

请参阅ProGuard手册>故障排除>警告:找不到引用的类

类似的问题总是相同的答案:

• 使用Proguard通过Dropbox.com库混淆Android应用程序
• Mobclix和Proguard
• 在Android上使用ProGuard
• Proguard告诉我'请先纠正上述警告.
• proguard地狱 - 找不到引用的类
• ProGuard与maven-android-plugin
