Proguard笔记

最近比较闲，重新整理了一下Proguard，主要是为了方便以后开发，简单记录下。

Proguard配置步骤：

step1
项目中添加proguard.cfg 文件

并写入内容如下：

# 声明不输出那些未找到的引用和一些错误，但续混淆-dontwarn # 指定执行几次优化，默认情况下，只执行一次优化-optimizationpasses 5#指定在混淆的时候不使用大小写混用的类名-dontusemixedcaseclassnames#指定读取引用库文件的时候不跳过非public类-dontskipnonpubliclibraryclasses#不优化输入的类文件 -dontoptimize#声明在处理过程中输出更多信息。添加这项配置之后，如果处理过程中出现异常，会输出整个StackTrace而不是一条简单的异常说明。-verbose#指定混淆是采用的算法，后面的参数是一个过滤器#这个过滤器是谷歌推荐的算法，一般不做更改-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*-keep enum com.facebook.**#---------------------#指定受保护的属性,不被混淆，可以有一个或者多个#----------------------keepattributes Exceptions,InnerClasses,Signature-keepattributes *Annotation*#跟踪异常信息-keepattributes SourceFile,LineNumberTable-keep public interface com.facebook.**-keep public interface com.tencent.**-keep public interface com.umeng.socialize.**-keep public interface com.umeng.socialize.sensor.**-keep public interface com.umeng.scrshot.**-keep public class com.umeng.socialize.* {*;}-keep public class javax.**-keep public class android.webkit.**-keep class com.facebook.**-keep class com.umeng.scrshot.**-keep public class com.tencent.** {*;}-keep class com.umeng.socialize.sensor.**-keep class com.tencent.mm.sdk.modelmsg.WXMediaMessage {*;}-keep class com.tencent.mm.sdk.modelmsg.** implements com.tencent.mm.sdk.modelmsg.WXMediaMessage$IMediaObject {*;}-keep class im.yixin.sdk.api.YXMessage {*;}-keep class im.yixin.sdk.api.** implements im.yixin.sdk.api.YXMessage$YXMessageData{*;}-keep public class [com.cmcc.enterprise].R$*{    public static final int *;}-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 * extends android.database.ContentObserver-keep public class com.android.vending.licensing.ILicensingService-keep public class android.util.Xml.** { *;}-keep public interface android.util.Xml.** { *;}-keep public class * extends android.support.v4.app.FragmentActivity-keep public class * extends android.support.v4.app.Fragment-keep public class * extends android.app.TabActivity-keep public class * extends android.app.Application-keep public class android.telephony.TelephonyManager-keep public class * extends android.os.AsyncTask#-keep class com.cmcc.numberportable.utils.** { *;}#-keep class com.cmcc.numberportable.util.** { *;}#-keep class com.cmcc.numberportable.dialog.** { *;}-keepattributes Signature#-keep class com.gmcc.issac_json.json.parse.** { *;}-keep class org.apache.http.** {    <fields>;

step2
在project.properties 文件中添加：

proguard.config=proguard.cfg

step3
打包即可。

Proguard 效果

Daxiong_dv_v0.0.3_20161206_1.apk 打包时没有进行混淆打包的，
Daxiong_dv_v0.0.3_20161206_2.apk 打包时则是执行了混淆工作。
可以看到混淆过后的apk比未混淆过的apk占用空间更小。

再看下反编译查看混淆过的apk，包名是经过混淆的，非常难读，activity 在proguard声明忽略混淆，故未被混淆。

再看下某个activity，成员变量被混淆了，无很难读懂代码。
