Android 代码混淆

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）友盟

-keep class com.umeng*.**{*;}
-keep public class * extends com.umeng.**
-keepclassmembers class * {
   public <init>(org.json.JSONObject);
}
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
-keep public class com.hx.wwy.R$*{
    public static final int *;
}
-dontwarn com.umeng*.**
-dontwarn com.umeng.** 

如果加了友盟的消息推送，需要另外加上如下命令：

-keep class com.umeng.message.* {
        public <fields>;
        public <methods>;
}


-keep class com.umeng.message.protobuffer.* {
        public <fields>;
        public <methods>;
}


-keep class com.squareup.wire.* {
        public <fields>;
        public <methods>;
}


-keep class com.umeng.message.local.* {
        public <fields>;
        public <methods>;
}
-keep class org.android.agoo.impl.*{
        public <fields>;
        public <methods>;
}

2）百度

-keep class com.baidu.** {*;}
-keep class vi.com.gdi.bgl.android.**{*;}
-dontwarn com.baidu.**

3）support.v4的

#-keep class android.support.v4.** {*; }
-keep interface android.support.v4.app.**{*;}
-dontwarn android.support.v4.**

4）gson

-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.stream.* { *; }
-keep class com.google.gson.examples.android.model.* { *; }
-keep class com.google.gson.* { *;}
-dontwarn com.google.gson.**

5）环信

-keep class com.easemob.** {*;}
-keep class org.jivesoftware.** {*;}
-keep class org.apache.** {*;}
-keep class com.hx.wwy.util.SmileUtils {*;}
-dontwarn  com.easemob.**
#2.0.9后加入语音通话功能，如需使用此功能的api
-dontwarn ch.imvs.**
-dontwarn org.slf4j.**
-keep class org.ice4j.** {*;}
-keep class net.java.sip.** {*;}
-keep class org.webrtc.voiceengine.** {*;}
-keep class org.bitlet.** {*;}
-keep class org.slf4j.** {*;}

-keep class ch.imvs.** {*;}

6）mob分享

-keep class com.mob.tools.**{*;}
-keep class android.net.http.SslError
-keep class android.webkit.**{*;}
-keep class cn.sharesdk.**{*;}
-keep class com.sina.**{*;}
-keep class com.alipay.share.sdk.**{*;}
-keep class **.R$* {
    *;
}
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}


-keep class com.jauker.widget.**{*;}
-keep class cn.sharesdk.wechat.friends.**{*;}
-keep class cn.sharesdk.wechat.utils.**{*;}
-keep class cn.sharesdk.tencent.qzone.**{*;}
-keep class cn.sharesdk.tencent.moments.**{*;}
-keep class cn.sharesdk.tencent.qq.**{*;}
-keep class cn.sharesdk.framework.**{*;}
-keep class cn.sharesdk.onekeyshare.**{*;}

7）nostra13 第三方图片处理库

-keep class com.nostra13.universalimageloader.** { *; }
-dontwarn com.nostra13.universalimageloader.**


#-keep class com.nostra13.universalimageloader.core.assist.**{*;}
#-keep class com.nostra13.universalimageloader.core.**{*;}
#-keep class com.nostra13.universalimageloader.cache.disc.**{*;}
#-keep class com.nostra13.universalimageloader.cache.memory.**{*;}
#-keep class com.nostra13.universalimageloader.utils.**{*;}

8）Xutil 的

#-keep class com.lidroid.xutils.**{*;}

9）Android本身的

-keep public class * extends android.app.Fragment
-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.app.View
-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.support.v4.**
-keep public class com.android.vending.licensing.ILicensingService
-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);
}
-keepclasseswithmembers class * {
    public <init>(android.content.Context);
}
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

下面粘贴一下我以前项目代码混淆的处理。
