我正在为Android开发应用程序,并使用Proguard混淆代码。
目前,我正在使用ProGuard配置:
-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
要维护在布局XML上使用的自定义组件名称,请执行以下操作:
-keep public class custom.components.**
要删除调试日志:
-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,请执行以下操作:
-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$Creator *;
}
问题是:
是否推荐其他标签?为什么以及为什么呢?
可以对proguard.cfg文件发表评论吗?我希望对某些行的执行情况发表评论,以使其他开发人员对我为什么添加它没有疑问。
同样在proguard中,是否可以维护文件的注释 header (具有版权)?如果不是,或者这不是一个好的政策,我应该在哪里添加版权?
最佳答案
Android SDK(r20或更高版本)
请检查project.properties中引用的预定义的proguard.config
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt

在这里,您可以检查我不断更新的 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Enabling ProGuard in Eclipse for Android,我最终得到了这个通用文件。我添加了注释以记住每一行的用途。它可能会帮助那里的人们,所以这里是:
-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);
