Android:Proguard 的推荐配置是什么? [英] Android: What are the recommended configurations for Proguard?

问题描述

我正在为 Android 开发应用程序并使用 Proguard 来混淆代码.

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

目前我正在使用 ProGuard 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

维护用于布局 XML 的自定义组件名称:

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

-keep public class custom.components.**

删除调试日志:

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

为了避免更改在布局的 onClick 上调用的方法的名称:

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 *;
}

问题是(是):

是否有其他标签推荐?为什么?为了什么?

Are any other tags recommended? Why and what for?

可以对 proguard.cfg 文件发表评论吗?我希望对某些行的行为进行评论，以便其他开发人员不会怀疑我添加的原因.

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.

同样在proguard中，是否可以维护文件的注释标题(具有版权)?如果不是，或者这不是一个好的政策，我应该在哪里添加版权?

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 SDK(r20 或更高版本)

请检查 project.properties 中引用的预定义 proguard.config

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

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

在这里您可以查看我不断更新的proguard默认"文件:https://medium.com/code-procedure-and-rants/android-my-standard-proguard-ffeceaf65521

Android SDK(r19 或更低版本)

根据我的回答 在 Eclipse for Android 中启用 ProGuard 我最终得到了这个通用文件.我添加了注释以记住每行的用途.它可能会帮助那里的人们，所以这里是:

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();
#}
