Android项目混淆打包

1）project.properties文件里面的内容：
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 yourproject 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.txtProject target.proguard.config=proguard.cfg
target=android-11
2）proguard.cfg 文件的内容：

-dontskipnonpubliclibraryclasses
-dontpreverify

1.引入默认的打包配置
拷贝${sdk.dir}/tools/proguard/proguard-android.txt文件中的配置到你的工程的proguard-android.txt中
如下所示
#系统配置
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# 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
# 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.

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
    native <methods>;
}

# 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*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-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>;
}

# The support library contains references to newer platform versions.
# Don‘t warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**

2.第三方jar包的配置
1）fastjson配置
#fast json相关
-libraryjars libs/json.jar                                 #fastjson的jar包不要混淆
-keep class com.alibaba.fastjson.** { *; }      #fastjson包下的所有类不要混淆，包括类里面的方法
-keepattributes Signature                            #这行一定要加上，否则你的object中含有其他对象的字段的时候会抛出ClassCastException

-dontwarn com.alibaba.fastjson.**              #告诉编译器fastjson打包过程中不要提示警告
2）xutils配置
#xutils相关
-libraryjars libs/xUtils-2.4.7.jar                      #xutils的jar包不要混淆
-keep class com.lidroid.** { *; }                     #xutils包下所有类不要混淆，包括类里面的方法
-keep class * extends java.lang.annotation.Annotation { *; }#注解包下的所有内容不要混淆，ViewUitls有用到

3）新浪微博配置
-libraryjars libs/weibosdkcore.jar                  #微博jar包不要混淆
-keep class com.sina.weibo.sdk.** { *; }         #微博报下所有类及类里面的内容都不要混淆

4）腾讯开放平台配置
-libraryjars libs/mta-sdk-1.6.2.jar                   #腾讯平台jar包不要混淆
-keep class com.tencent.** { *; }                     #腾讯平台jar包中所有类及类里面的内容不要混淆

5）图片异步加载组件universal-image-loader配置
#图片加载
-libraryjars libs/universal-image-loader-1.8.4-with-sources.jar  #imageLoader的jar包不要混淆
-keep class com.nostra13.universalimageloader.** { *; }              #imageLoader包下所有类及类里面的内容不要混淆

6）友盟统计组件配置
#友盟相关
-libraryjars libs/umeng-analytics-v5.2.3.jar     #友盟统计的jar包不要混淆
-keep class com.umeng.** { *; }                        #友盟统计jar包下的所有类及类里面的所有内容不要混淆

7）自定义控件及组件不要打包混淆
如果我们自定了ListView,ScrollView,Gallery这些组件的时候，我们就不能混淆这些自定义的类了，因为在layout里面我们已经引用这个了类，而且已经写死了。同样四大组件也是不能打包混淆的
#四大组件不能混淆
-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
#自定义控件不要混淆
-keep public class * extends android.view.View {*;}

8）数据适配器adapter不要混淆
#adapter也不能混淆
-keep public class * extends android.widget.BaseAdapter {*;}

如果你使用了CusorAdapter,添加下面这行
-keep public class * extends android.widget.CusorAdapter{*;}
同样如果你觉得麻烦，就直接将BaseAdpater换成Adapter
9）数据模型不要混淆
-keepnames class * implements java.io.Serializable     #比如我们要向activity传递对象使用了Serializable接口的时候，这时候这个类及类里面#的所有内容都不能混淆
-keepclassmembers class * implements java.io.Serializable {
        *;
}

-keep class com.xx.xxx.domain.* {*;}
-keep class com.xx.xxx.vo.* {*;}

-keep class com.xx.xxx.model.* {*;}
这里的包名取决你自己定义的model所在包的名称
10）百度地图组件配置
#百度地图相关
-libraryjars libs/baidumapapi_v2_4_0.jar        #地图相关的jar包不要混淆
-keep class com.baidu.** { *; }                         #地图组件包括图层、定位等接口所有的类及类里面的内容都不要混淆
-keep class vi.com.gdi.bgl.android.**{*;}         #交通实况相关的类及类里面的所有内容不要混淆
-libraryjars libs/locSDK_3.1.jar                         #定位jar包不要混淆
-libraryjars libs/armeabi/libBaiduMapSDK_v2_4_0.so  #地图相关的C++编译的可执行文件（引擎）不要混淆
-libraryjars libs/armeabi/liblocSDK3.so                         #定位相关的C++编译的可执行文件（引擎）不要混淆

这里要特别说明的是百度地图这个apiKey，一定要注意测试的时候与打包发布时候的SHA1是不一样的，所以需要准备两个apiKey。
所以打包的时候一定要把apiKey设置成打包所需的apiKey，否则打包后的apk文件运行后图层无法加载，但是定位功能不受影响
具体的操作是在打包最后一步把你的SHA1码拷贝一份到应用控制台重新生成一个key，如果你使用的是baidumapapi3.0以上的SDK就没有这么多麻烦事了
打包所需key生成如下图所示

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