Android项目混淆打包

以下为我此期项目中的关于混淆打包的总结：
（本人第一次混淆打包，呵呵，错误很多！列了一些比较头疼的）
一、项目混淆过程中注意事项：
由于我的sdk版本较高，因此新建android项目下只有proguard-project.txt和project.properties这两个文件夹，而网上一些所谓混淆的方法我均试验了下，都有或多或少的问题，以下是一些混淆总结：
1、如果你的项目没有其他第三方包的话，那么进行混淆很简单，只需要将project.properties文件夹下面的注释解开就行，一点区别在于：如果您是2.3之前的sdk版本，那么就用这个proguard.config=proguard.cfg
如果是之后的则为：proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt（当然视您生成项目时候该文件具体生成情况所定）。
2、如果有第三方lib包的话，则混淆时需要注意了，以下是常用的一些lib包的混淆配置：

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=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txtProject target.proguard.config=proguard.cfg
target=android-11
2）proguard.cfg 文件的内容：
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keepclasseswithmembernames class * {
native ;
}
-keepclasseswithmembers class * {
public (android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembers class * {
public (android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
-libraryjars libs/umeng_sdk.jar
-keepclassmembers class * {
public (org.json.JSONObject);
}
-keep public class com.smile.android.R$*{
public static final int *;
}

-keep class android.support.v4.** { *; }
-libraryjars /libs/nineoldandroids-2.4.0.jar
-dontwarn com.nineoldandroids.**
-keep class com.nineoldandroids.** { *;}

注：（对呀lib包的混淆配置，一般放到此文件的最后面！）
二、混淆打包后的错误收集：
1、如果项目中含有数据库并且数据库的创建方式为通过实现BaseColumns类来依次创建数据库表的话，那么在混淆之后会出现no such table这类的错误，这个错误困扰我一晚上了，实在想不通，后面觉得应该是混淆过程中将包名混淆了导致编译器找不到该表。
解决办法：换数据库的创建方式：直接在继承自SQLiteOpenHelper中执行表格创建即：db.execSQL(DB_CREAT);这样一来就不会出错了！很奇葩的解决方法，还是回归原始比较好！

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

# 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.

# Add any project specific keep options here:
