Android studio混淆
看了一篇关于Android studio混淆的文章http://blog.csdn.net/qq_23547831/article/details/51581491，感觉有必要总结一个简单的混淆版本设置，所以有了以下文章：
1.首先需要在app下的build.gradle下配置，true表示编译时会混淆代码
<span style="font-size:18px;">buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }</span>
2.在proguard-rules.pro中配置，以下是基本配置
<span style="white-space:pre"> </span><pre name="code" class="html"><span style="white-space:pre"> </span>-dontshrink #指定代码的压缩级别 -optimizationpasses 5 #包明不混合大小写 -dontusemixedcaseclassnames #不去忽略非公共的库类 -dontskipnonpubliclibraryclasses #优化 不优化输入的类文件 -dontoptimize #不做预校验 -dontpreverify #混淆时是否记录日志 -verbose # 混淆时所采用的算法 -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* #保护注解 -keepattributes *Annotation* # 保持哪些类不被混淆 -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.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 #如果有引用v4包可以添加下面这行 -keep public class * extends android.support.v4.app.Fragment #忽略警告 -ignorewarning ##记录生成的日志数据,gradle build时在本项目根目录输出## #apk 包内所有 class 的内部结构 -dump class_files.txt #未混淆的类和成员 -printseeds seeds.txt #列出从 apk 中删除的代码 -printusage unused.txt #混淆前后的映射 -printmapping mapping.txt ########记录生成的日志数据，gradle build时 在本项目根目录输出-end###### #####混淆保护自己项目的部分代码以及引用的第三方jar包library####### #-libraryjars libs/umeng-analytics-v5.2.4.jar #三星应用市场需要添加:sdk-v1.0.0.jar,look-v1.0.1.jar #-libraryjars libs/sdk-v1.0.0.jar #-libraryjars libs/look-v1.0.1.jar #如果不想混淆 keep 掉 -keep class com.lippi.recorder.iirfilterdesigner.** {*; } #项目特殊处理代码 #忽略警告 -dontwarn com.lippi.recorder.utils** #保留一个完整的包 -keep class com.lippi.recorder.utils.** { *; } -keep class com.lippi.recorder.utils.AudioRecorder{*;} #如果引用了v4或者v7包 -dontwarn android.support.** ####混淆保护自己项目的部分代码以及引用的第三方jar包library-end#### -keep public class * extends android.view.View { public <init>(android.content.Context); public <init>(android.content.Context, android.util.AttributeSet); public <init>(android.content.Context, android.util.AttributeSet, int); public void set*(...); } #保持 native 方法不被混淆 # -keepclasseswithmembernames class * { # native <methods>; # } # Keep names - Native method names. Keep all native class/method names. -keepclasseswithmembers,allowshrinking 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); } #保持自定义控件类不被混淆 -keepclassmembers class * extends android.app.Activity { public void *(android.view.View); } #保持 Parcelable 不被混淆 -keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; } #保持 Serializable 不被混淆 -keepnames class * implements java.io.Serializable #保持 Serializable 不被混淆并且enum 类也不被混淆 -keepclassmembers class * implements java.io.Serializable { static final long serialVersionUID; private static final java.io.ObjectStreamField[] serialPersistentFields; !static !transient <fields>; !private <fields>; !private <methods>; private void writeObject(java.io.ObjectOutputStream); private void readObject(java.io.ObjectInputStream); java.lang.Object writeReplace(); java.lang.Object readResolve(); } #保持枚举 enum 类不被混淆 如果混淆报错，建议直接使用上面的 -keepclassmembers class * implements java.io.Serializable即可 #-keepclassmembers enum * { # public static **[] values(); # public static ** valueOf(java.lang.String); #} -keepclassmembers class * { public void *ButtonClicked(android.view.View); } #不混淆资源类 -keepclassmembers class **.R$* { public static <fields>; }
如果有H5交互页面配置如下
<span style="white-space:pre"> </span> #不混淆H5交互 -keepattributes *JavascriptInterface* <span style="white-space:pre"> </span> #ClassName是类名，H5_Object是与javascript相交互的object，建议以内部类形式书写 -keepclassmembers class **.ClassName$H5_Object{ *; }
如果使用GSON，则添加如下配置
<span style="white-space:pre"> </span> -keepattributes Signature -keepattributes *Annotation*<pre name="code" class="html"><span style="white-space:pre"> </span> -keep class sun.misc.Unsafe { *; }
<span style="white-space:pre"> </span> #下面需要填写自己bean对象对应的包名，所以建议将使用Gson解析的都放在同一包下<pre name="code" class="html"><span style="white-space:pre"> </span> -keep class com.dingyan.students.javabean.** { *; }
如果使用了其它的第三方包，则需要参照文档进行配置，否则会有莫名其妙的错误。
最后贴上我项目中实际的混淆方案：

除了apk源代码的混淆之外还有资源文件的混淆：
微信推出了一款apk资源混淆方案，该方案的具体原理见：安装包立减1M–微信Android资源混淆打包工具
