Java代码混淆（把类和变量混淆成诸如abcdefg的样子）

首先下载混淆工具： http://proguard.sourceforge.net/downloads.html 如果你是初学者，又急于使用混淆功能，不用去找其他什么工具了，就这个就够了。 第一步：将我们的代码从eclipse中以普通export的方式导出成一个jar包，只导出src中的代码，其他钩全部去掉，右边的那些资源文件什么的也要去掉钩。导出之后放在桌面，直到混淆完成之前都不要移动这个jar包。 第二步：打开我们的混淆工具之后，点击Input/Output，然后Add Input，选择我们刚才export的那个jar，然后点击Add Output，选择混淆之后的jar输出路径和文件名，这里也放在桌面。 第三步，在桌面新建一个lib文件夹，将我们在第一步里标注的libs里面引用到的jar全部找出来，放在桌面的lib文件夹里。然后点击右边的Add，将这些jar文件添加进去。 第四步，点击process，然后点击save configuration，保存配置文件到桌面。然后编辑这个文件，添加： -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 -keep class com.vzone.tmdsdk.TMDAgent {*;}#不要混淆我们的入口类 -keep public class * extends android.app.Activity # 保持哪些类不被混淆 -keep public class * extends android.app.Application # 保持哪些类不被混淆 -keep public class * extends android.app.Service # 保持哪些类不被混淆 -keep public class * extends android.content.BroadcastReceiver # 保持哪些类不被混淆 -keep public class * extends android.content.ContentProvider # 保持哪些类不被混淆 -keep public class * extends android.app.backup.BackupAgentHelper # 保持哪些类不被混淆 -keep public class * extends android.preference.Preference # 保持哪些类不被混淆 -keep public class com.android.vending.licensing.ILicensingService # 保持哪些类不被混淆保存该配置文件 第五步， 点击Proguard按钮，点击Load configration按钮，导入上面配置好的混淆文件。点击左边的Process，点击右下角的Process!，直到完成，搞定。 完整配置文件参考： -injars tmdsdk.jar -outjars tmdsdk-mixed.jar -libraryjars 'D:\software\jdk\jre\lib\rt.jar' -libraryjars lib\android-support-v4.jar -libraryjars lib\android.jar -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 -keep class com.vzone.tmdsdk.TMDAgent {*;} -keep public class * extends android.app.Activity # 保持哪些类不被混淆 -keep public class * extends android.app.Application # 保持哪些类不被混淆 -keep public class * extends android.app.Service # 保持哪些类不被混淆 -keep public class * extends android.content.BroadcastReceiver # 保持哪些类不被混淆 -keep public class * extends android.content.ContentProvider # 保持哪些类不被混淆 -keep public class * extends android.app.backup.BackupAgentHelper # 保持哪些类不被混淆 -keep public class * extends android.preference.Preference # 保持哪些类不被混淆 -keep public class com.android.vending.licensing.ILicensingService # 保持哪些类不被混淆 -keepclasseswithmembernames class * { # 保持 native 方法不被混淆 native ; } -keepclasseswithmembers class * { # 保持自定义控件类不被混淆 public (android.content.Context, android.util.AttributeSet); } -keepclasseswithmembers class * {# 保持自定义控件类不被混淆 public (android.content.Context, android.util.AttributeSet, int); } -keepclassmembers class * extends android.app.Activity { # 保持自定义控件类不被混淆 public void *(android.view.View); } -keepclassmembers enum * { # 保持枚举 enum 类不被混淆 public static **[] values(); public static ** valueOf(java.lang.String); } -keep class * implements android.os.Parcelable { # 保持 Parcelable 不被混淆 public static final android.os.Parcelable$Creator *; } # Keep - Applications.
