安卓混淆

eclipse混淆

在工程目录proguard-project.txt编写那些需要混淆

#第三方引入的包-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/baidumapapi.jar-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-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 <methods>;}-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);}-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.** {*;}#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

project.properties文件中

#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

把上面的#去掉

Studio

1. 在build.grandle添加，其中规则写在proguard-rules.pro中，也可以自定义一个文件，将其代替，比如eclipse常用的 proguard-project.txt

   buildTypes {  release {    signingConfig signingConfigs.release    minifyEnabled true    proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-rules.pro‘  }}

2. 在proguard-rules.pro中加入以下代码，基本可以涵盖所有

   -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 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 <methods>;}-keepclasseswithmembers class * {   # 保持自定义控件类不被混淆    public <init>(android.content.Context, android.util.AttributeSet);}-keepclasseswithmembers class * {# 保持自定义控件类不被混淆    public <init>(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 *;}

3. 通过 Android Studio进行 混淆代码时，默认已经将 lib目录中的 jar 都已经添加到打包脚本中，所以不需要再次手动添加，否则会出现“ java.io.IOException: The same input jar is specified twice” 错误。
