在Eclipse中启用的ProGuard为Android [英] Enabling ProGuard in Eclipse for Android

问题描述

在 ProGuard的为Android的新文档说，添加一行到default.properties文件在项目主目录。然而，在打开此文件，我看了顶部：

The new documentation on ProGuard for Android says to add a line to the default.properties file in the project home directory. However, on opening this file, I read at the top:

# This file is automatically generated by Android Tools. 
# Do not modify this file -- YOUR CHANGES WILL BE ERASED! 

我缺少的东西？

Am I missing something?

此外，有没有一种方法，使ProGuard的只为生产版本在Eclipse（即出口成品时）？

Also, is there a way to enable ProGuard only for a production build from Eclipse (i.e., when exporting the finished product)?

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

更多信息：<一href="http://proguard.sourceforge.net/manual/examples.html#androidapplication">http://proguard.sourceforge.net/manual/examples.html#androidapplication

Android的SDK（R19或更低）

您可以将它添加到default.properties。我一直在手动添加，而无需一个问题为止。

You can add it to the default.properties. I've been adding manually without having a problem so far.

如果您添加一行：

proguard.config=proguard.cfg

正如表示，将只使用ProGuard的导出时签署的申请（安卓工具=>导出签名的应用程序）

As said it will only use ProGuard when exporting signed application (Android Tools => Export Signed Application)

如果你开始了Android 2.3之前的SDK将不会创建（旁边的 default.properties proguard.cfg 文件的项目code>在2.3>）。

If you start the project with the SDK before Android 2.3 the proguard.cfg file will not be created (next to default.properties as in 2.3>).

要启用自动创建它，只是简单地更新到Android 2.3的SDK，并创建与现有资源（这是该项目当前已的来源）的新项目。

To enable automatic creation of it, just simply update to the SDK of Android 2.3 and create a new project with existing sources (which are the sources of the project you currently have).

自动地在 proguard.cfg 填充将被创建。

Automagically the proguard.cfg fill will be created.

如果是，您要创建手动这是它应该包括：

If still, you want to create it manually this is what it should contain:

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontwarn android.support.**
-verbose

-dontoptimize
-dontpreverify


-keepattributes *Annotation* 
-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.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment

-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 public class * extends android.view.View {
  void set*(***);
  *** get*();
 }

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

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

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

我想我已经回答了上面的所有问题。

I think I've answered all the questions above.

更新

这是一行一行的解释：

#Use 5 step of optimization 
#-optimizationpasses 5

#When not preverifing in a case-insensitive filing system, such as Windows. This tool will unpack your processed jars,(if using windows you should then use):
-dontusemixedcaseclassnames

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

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).    
-dontoptimize
-dontpreverify

-dontwarn android.support.**

#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/*

# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.

#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 * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
#Compatibility library 
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment

#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.**

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
 -keepclassmembers public class * extends android.view.View {
  void set*(***);
  *** get*();
}

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

#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:
-keep public class * extends android.view.View {
    public <init>(android.content.Context);
}
-keep public class * extends android.view.View {
    public <init>(android.content.Context, android.util.AttributeSet);
}
-keep public class * extends android.view.View {
    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();
#}

更新2：

在最新的ADT / Proguard的使用 -keepclasseswithmembers ，而不是 -keepclasseswithmembernames

In the most recent ADT/Proguard use -keepclasseswithmembers instead of -keepclasseswithmembernames
