有关android安全性的问题--代码混淆

转自：http://www.cnblogs.com/dream-sky/archive/2012/11/15/2771648.html

在project.properties里加上 proguard.config=proguard.cfg

proguard.cfg 配置如下：

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#忽略警告也可以用-ignorewarnings
-dontwarn

#声明第三方jar包,不用管第三方jar包中的.so文件(如果有)
-libraryjars libs/tencent_openapi.jar
-libraryjars libs/httpmime-4.1.3.jar
-libraryjars libs/weibo.sdk.android.sso.jar
-libraryjars libs/android-support-v4.jar

-libraryjars libs/AHibernate-1.1.jar
-libraryjars libs/core.jar
-libraryjars libs/gson-1.6.jar

-libraryjars libs/android-support-v4.jar
-libraryjars libs/baidumapapi_v2_1_2.jar
-libraryjars libs/locSDK_3.1.jar
-libraryjars libs/pinyin4j-2.5.0.jar

-keepclasseswithmembers class * {

-keepclassmembers class * extends android.app.Activity {

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

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

#不混淆第三方jar包中的类
-keep class com.baidu.mapapi.** {*;}
-keep class com.tencent.tauth.** {*;}
-keep class org.apache.http.entity.mime.** {*;}
-keep class android.support.v4.** {*;}
-keep class android.net.http.** {*;}
-keep class com.weibo.sdk.android.** {*;}
-keep class com.sina.sso.** {*;}

-keep interface net.sourceforge.pinyin4j.** { *; }
-keep interface vi.com.gdi.bgl.android.** { *; }
-keep interface cn.sharesdk.** { *; }

说明一下，第三方jar包中如果有.so文件，不用去理会，引入的第三方jar文件不要混淆，否则可能会报异常
