Android 工程在4.0基礎上混淆

Android如今對安全方面要求比較高了，我今天要作的對apk進行混淆，用全部的第三方工具都不能反編譯，做者的知識產權獲得保障了，是否是碉堡了。

 

一，首先說明我這是在4.0基礎上進行的。

 

先看看project.properties 這個文件。

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
# proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.
target=android-17
#proguard.config=proguard.cfg
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

 

先把proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 的註釋去掉。

 

其實混淆的難點就是項目引進了第三方包，若是沒有引入第三方包，直接把上面的東西註釋掉就能夠混淆了，若是引入了第三方包就比較麻煩，請看下面。

 

 

 

再把第三方包進行添加，注意，通常第三方jar已經混淆過了，因此不能再次混淆。下面是我把第三方jar包過濾掉的操做。通常方在最下面。

 

 

這個文件proguard-project.txt

 

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

#-keep class packagename.** {*;}

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}
-keepclasseswithmembernames class * {
native <methods>;
}

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}

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

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

-dontwarn com.umeng.**

-dontwarn org.apache.commons.**

-dontwarn com.tencent.weibo.sdk.**

-keepattributes *Annotation*

-keep class com.umeng*.** {*; }

-keep public class [your_pkg].R$*{
public static final int *;
}
-keep class com.tencent.open.TDialog$*

-keep class com.tencent.open.TDialog$* {*;}

-keep class com.tencent.open.PKDialog

-keep class com.tencent.open.PKDialog {*;}

-keep class com.tencent.open.PKDialog$*

-keep class com.tencent.open.PKDialog$* {*;}

-keep class com.tencent.mm.sdk.openapi.WXMediaMessage {*;}

-keep class com.tencent.mm.sdk.openapi.** implements com.tencent.mm.sdk.openapi.WXMediaMessage$IMediaObject {*;}

 

-libraryjars /libs/achartengine-1.1.0.jar
-dontwarn achartengine.**
-keep class achartengine.** { *;}

-libraryjars /libs/android-support-v4.jar
-dontwarn android.support.v4.**
-keep class android.support.v4.** { *;}

-libraryjars /libs/jpush-sdk-release1.4.0.jar
-dontwarn jpush.sdk.release.**
-keep class jpush.sdk.release.** { *;}

-libraryjars /libs/umeng_sdk.jar
-dontwarn umeng.sdk.**
-keep class umeng.sdk.** { *;}

-libraryjars /libs/umeng_social_sdk.jar
-dontwarn umeng.social.sdk.**
-keep class umeng.social.sdk.** { *;}

-libraryjars /libs/universal-image-loader.jar
-dontwarn universal.image.loader.**
-keep class universal.image.loader.** { *;}

-libraryjars /libs/ShareSDK-SinaWeibo-2.1.2.jar
-dontwarn cn.sharesdk.sina.weibo.**
-keep class cn.sharesdk.sina.weibo.** { *;}

-libraryjars /libs/ShareSDK-TencentWeibo-2.1.2.jar
-dontwarn cn.sharesdk.tencent.weibo.**
-keep class cn.sharesdk.tencent.weibo.** { *;}

-libraryjars /libs/ShareSDK-Wechat-Moments-2.1.2.jar
-dontwarn cn.sharesdk.wechat.moments.**
-keep class cn.sharesdk.wechat.moments.** { *;}

 

 

這些對應上面的jar包，防止再次混淆。

 

-braryjars libs/nineoldandroids-2.4.0.jar----指明lib包的在工程中的路徑
而-dontwarn com.xx.bbb.**和-keep class com.xx.bbb.** { ;}
這兩個參數用來保持第三方庫中的類而不亂，將-dontwarn和-keep 結合使用，意思是保持com.xx.bbb.*這個包裏面的全部類和全部方法而不混淆，接着還叫ProGuard不要警告找不到com.xx.bbb.**這個包裏面的類的相關引用。

 

-libraryjars ..\第三方庫的工程名
-dontwarn  包名.**
-keep class 包名.** { *;}

 

最後打包簽名，成功。

 

完畢。
