安卓：什么是Proguard的推荐的配置？ [英] Android: What are the recommended configurations for Proguard?

问题描述

我正在开发的Andr​​oid应用程序，并使用Proguard的混淆了code。

I'm developing apps for Android and using Proguard to obfuscate the code.

目前我使用ProGuard的配置：

Currently i'm using ProGuard configurations:

-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 com.android.vending.licensing.ILicensingService

要维护那些在布局XML中使用自定义组件名称：

To maintain custom components names that are used on layouts XML:

-keep public class custom.components.**

要删除调试日志：

-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
}

要避免更改布局上的onClick调用的方法名：

To avoid changing names of methods invoked on layout's onClick:

-keepclassmembers class * {
 public void onClickButton1(android.view.View);
 public void onClickButton2(android.view.View);
 public void onClickButton3(android.view.View);
}

-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 *;
}

现在的问题是（有）：

The question is (are):

任何其他标​​记建议？为什么以及什么？

Are any other tags recommended? Why and what for?

这有可能使一个proguard.cfg文件有何评论？我想有它的一些东西线都是这样做的，其他开发人员不必为什么我添加的怀疑意见。

It's possible to make a comment on a proguard.cfg file? I would like to have it with comments for what some lines are doing so that other developers don't have doubts about why i added.

此外，在ProGuard的，是有可能保持一个文件（版权）的评论标题？如果不是，或者它是不是一个好政策，我应该在哪里添加的版权？

Also in proguard, is it possible to maintain the comment header of a file (with the copyright)? If it's not, or it's not a good policy where should i add the copyright?

推荐答案

Android的SDK（R20或更高版本）

请检查predefined proguard.config refered在project.properties

Please check the predefined proguard.config refered in project.properties

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt

Android的SDK（R19或更低）

href="http://stackoverflow.com/questions/4732656/enabling-proguard-in-eclipse-for-android/5040675#5040675">Enabling ProGuard的Eclipse中为Android 我已经结束了这个通用的文件。我已经添加注释记住每个线对。它可以帮助的人在那里所以在这里，它是：

Based on my answer Enabling ProGuard in Eclipse for Android I've ended up with this generic file. I've added comments to remember what each line is for. It might help people out there so here it is:

-optimizationpasses 5

#When not preverifing in a case-insensitive filing system, such as Windows. Because this tool unpacks your processed jars, you should then use:
-dontusemixedcaseclassnames

#Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
-dontskipnonpubliclibraryclasses

#Preverification is irrelevant for the dex compiler and the Dalvik VM, so we can switch it off with the -dontpreverify option.
-dontpreverify

#Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
-verbose

#The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).
#To understand or change this check http://proguard.sourceforge.net/index.html#/manual/optimizations.html
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#To repackage classes on a single package
#-repackageclasses ''

#Uncomment if using annotations to keep them.
#-keepattributes *Annotation*

#Keep classes that are referenced on the AndroidManifest
-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 com.android.vending.licensing.ILicensingService


#To remove debug logs:
-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
}

#To avoid changing names of methods invoked on layout's onClick.
# Uncomment and add specific method names if using onClick on layouts
#-keepclassmembers class * {
# public void onClickButton(android.view.View);
#}

#Maintain java native methods 
-keepclasseswithmembernames class * {
    native <methods>;
}

#To maintain custom components names that are used on layouts XML.
#Uncomment if having any problem with the approach below
#-keep public class custom.components.package.and.name.**

#To maintain custom components names that are used on layouts XML:
-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);
}

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

#To keep parcelable classes (to serialize - deserialize objects to sent through Intents)
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

#Keep the R
-keepclassmembers class **.R$* {
    public static <fields>;
}

###### ADDITIONAL OPTIONS NOT USED NORMALLY

#To keep callback calls. Uncomment if using any
#http://proguard.sourceforge.net/index.html#/manual/examples.html#callback
#-keep class mypackage.MyCallbackClass {
#   void myCallbackMethod(java.lang.String);
#}

#Uncomment if using Serializable 
#-keepclassmembers class * implements java.io.Serializable {
#    private static final java.io.ObjectStreamField[] serialPersistentFields;
#    private void writeObject(java.io.ObjectOutputStream);
#    private void readObject(java.io.ObjectInputStream);
#    java.lang.Object writeReplace();
#    java.lang.Object readResolve();
#}
