Android：Proguard的推荐configuration是什么？
我正在开发面向Android的应用程序，并使用Proguard来混淆代码。
目前我正在使用ProGuardconfiguration：
-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 维护在布局XML上使用的自定义组件名称：
-keep public class custom.components.**
删除debugging日志：
-assumenosideeffects class android.util.Log { public static *** d(...); public static *** v(...); }
要避免更改在布局的onClick上调用的方法的名称：
-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$Creator *; }
现在的问题是：
是否有其他标签推荐？ 为什么和为了什么？
可以对proguard.cfg文件发表评论吗？ 我想为它的一些行正在做的评论，以便其他开发人员不会怀疑我为什么添加。
在proguard中，是否可以维护一个文件的注释标题（具有版权）？ 如果不是，或者这不是一个好的政策，我应该在哪里添加版权？
Android SDK（r20或更高版本）
请检查在project.properties中提到的预定义的proguard.config
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt

Android SDK（r19或更低）
基于我的答案启用Android的Eclipse中的ProGuard我已经结束了这个通用文件。 我已经添加了评论来记住每一行的用途。 它可以帮助那里的人，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.

对于使用Ant或Eclipse的标准构build ，Android SDK（r20或更高版本）已经提供了一个合适的configuration，由project.properties文件中的proguard.config属性引用（如Michal在他的答案中指出的）。 在旧版本中，你总是需要指定自己的完整configuration，所以老的build议（如第一个答案）可能会导致一些混淆。
对于定制版本 ，您可以在ProGuard手册 > 示例 > 完整的Android应用程序中find最新推荐的configuration。 Proguard发行版还包含示例文件examples / android.pro
值得注意的是，你可能想保留注释和设置器在视图扩展。
您可以在散列字符“＃”之后添加注释，如示例文件中所做的广泛操作。
在名为project.properties的项目文件中，设置以下值：
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt
这将从Android SDK采取最新版本的Proguard设置。
