开启混淆:
设置两个属性为true

配置好混淆规则,对应用签名打包即可:

混淆规则文件:proguard-rules.pro

基础混淆规则:

-optimizationpasses 5         # 指定代码的压缩级别-dontusemixedcaseclassnames   # 是否使用大小写混合-dontpreverify           # 混淆时是否做预校验-verbose               # 混淆时是否记录日志-optimizations !code/simplification/arithmetic,!field/*,!class/merging/* # 混淆时所采用的算法#不混淆需要根据manifest来识别的类-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   # 保持 native 方法不被混淆-keepclasseswithmembernames class * {     native <methods>;}# 保持自定义控件类不被混淆-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);}# 保持枚举 enum 类不被混淆-keepclassmembers enum * {         public static **[] values();    public static ** valueOf(java.lang.String);}# 保持 Parcelable 不被混淆-keep class * implements android.os.Parcelable {     public static final android.os.Parcelable$Creator *;}

依赖注入的框架需要加上其避免混淆规则:
比如butterknife:
http://jakewharton.github.io/butterknife/

-keep class butterknife.** { *; }-dontwarn butterknife.internal.**-keep class **$$ViewBinder { *; }-keepclasseswithmembernames class * {    @butterknife.* <fields>;}-keepclasseswithmembernames class * {    @butterknife.* <methods>;}

关于qq,微信,sina的jar包的混淆规则:
http://dev.umeng.com/social/android/login-page

-dontshrink-dontoptimize-dontwarn com.google.android.maps.**-dontwarn android.webkit.WebView-dontwarn com.umeng.**-dontwarn com.tencent.weibo.sdk.**-dontwarn com.facebook.**#-libraryjars libs/SocialSDK_QQZone_2.jar   # 注意,这条会报重复混淆,要注释掉-keep enum com.facebook.**-keepattributes Exceptions,InnerClasses,Signature-keepattributes *Annotation*-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 [your_pkg].R$*{    public static final int *;}

报错:找不到某个jar包中的类:
解决方法:不混淆这个jar包:

# 不混淆七牛的jar包#（声明lib文件）-libraryjars **.jar#（不提示警告）-dontwarn com.xx.bbb.**#（不进行混淆）-keep class com.xx.bbb.** { *;}#-libraryjars libs/qiniu-android-sdk-7.0.9.jar -->jar包已被统一声明,所以这里不用再重复声明-dontwarn com.qiniu.android.**-keep class com.qiniu.android.** { *;}

至此,打包可以成功:

运行,eventbus报错:
说明eventbus的包不能混淆
解决:保留eventbus中的类,以及我们的类中的onevent方法:

#eventbus -dontwarn de.greenrobot.event.**-keep class de.greenrobot.event.** { *; }-keepclassmembers class ** {    public void onEvent*(**);    void onEvent*(**);}

javabean类多层调用时空指针:
找不到内部的类:
解决:不混淆domain包下的javabean:

# 保留domain包中的类-keep class com.qxinli.android.domain.** { *; }

其他:
不混淆volley,jpush:

# volley-keep class com.android.volley.** {*;}-keep class com.android.volley.toolbox.** {*;}-keep class com.android.volley.Response$* { *; }-keep class com.android.volley.Request$* { *; }-keep class com.android.volley.RequestQueue$* { *; }-keep class com.android.volley.toolbox.HurlStack$* { *; }-keep class com.android.volley.toolbox.ImageLoader$* { *; }#jpush#-libraryjars libs/jpush-sdk-release1.6.3.jar-dontwarn cn.jpush.**-keep class cn.jpush.** { *; }

最终:混淆成功
