Android Studio常用混淆配置

为了防止自己的劳动成果被别人窃取，混淆代码能有效防止被反编译，首先要在build.gradle中开启混淆，也就是minifyEnabled true，我用的build.gradle具体如下所示：

def releaseTime() {    return new Date().format("yyyy.MM.dd", TimeZone.getTimeZone("UTC"))}android {    ....     buildTypes {        release {            // 混淆            minifyEnabled true            // Zipalign优化            zipAlignEnabled true            // 移除无用的resource文件            shrinkResources true            // 前一部分代表系统默认的android程序的混淆文件，后一个文件是自己的定义混淆文件            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            applicationVariants.all { variant ->                variant.outputs.each { output ->                    def outputFile = output.outputFile                    if (outputFile != null && outputFile.name.endsWith('.apk')) {                        // 输出apk名称为appname-1.0-beta1-xxxx-xx-xx.apk                        def fileName = "app-${defaultConfig.versionName}-beta1-${releaseTime()}.apk"                        output.outputFile = new File(outputFile.parent, fileName)                    }                }            }        }    }    ....}

上面注释中写到proguard-android.txt文件，这是系统默认的混淆文件，具体在../sdk/tools/proguard/目录下，其中包含了android最基本的混淆，一般不需要改动，我们需要配置的是项目中app下的proguard-rules.pro文件，在此提供一份混淆模板。

#############################################  #  # 对于一些基本指令的添加  #  #############################################  # 代码混淆压缩比，在0~7之间，默认为5，一般不做修改  -optimizationpasses 5    # 混合时不使用大小写混合，混合后的类名为小写  -dontusemixedcaseclassnames    # 指定不去忽略非公共库的类  -dontskipnonpubliclibraryclasses    # 这句话能够使我们的项目混淆后产生映射文件  # 包含有类名->混淆后类名的映射关系  -verbose    # 指定不去忽略非公共库的类成员  -dontskipnonpubliclibraryclassmembers    # 不做预校验，preverify是proguard的四个步骤之一，Android不需要preverify，去掉这一步能够加快混淆速度。  -dontpreverify    # 保留Annotation不混淆  -keepattributes *Annotation*,InnerClasses    # 避免混淆泛型  -keepattributes Signature    # 抛出异常时保留代码行号  -keepattributes SourceFile,LineNumberTable    # 指定混淆是采用的算法，后面的参数是一个过滤器  # 这个过滤器是谷歌推荐的算法，一般不做更改  -optimizations !code/simplification/cast,!field/*,!class/merging/*    #############################################  #  # Android开发中一些需要保留的公共部分  #  #############################################    # 保留我们使用的四大组件，自定义的Application等等这些类不被混淆  # 因为这些子类都有可能被外部调用  -keep public class * extends android.app.Activity  -keep public class * extends android.app.Appliction  -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 * extends android.view.View  -keep public class com.android.vending.licensing.ILicensingService    # 保留support下的所有类及其内部类  -keep class android.support.** {*;}    # 保留继承的  -keep public class * extends android.support.v4.**  -keep public class * extends android.support.v7.**  -keep public class * extends android.support.annotation.**    # 保留R下面的资源  -keep class **.R$* {*;}    # 保留本地native方法不被混淆  -keepclasseswithmembernames class * {      native <methods>;  }    # 保留在Activity中的方法参数是view的方法，  # 这样以来我们在layout中写的onClick就不会被影响  -keepclassmembers class * extends android.app.Activity{      public void *(android.view.View);  }    # 保留枚举类不被混淆  -keepclassmembers enum * {      public static **[] values();      public static ** valueOf(java.lang.String);  }    # 保留我们自定义控件（继承自View）不被混淆  -keep public class * extends android.view.View{      *** get*();      void set*(***);      public <init>(android.content.Context);      public <init>(android.content.Context, android.util.AttributeSet);      public <init>(android.content.Context, android.util.AttributeSet, int);  }    # 保留Parcelable序列化类不被混淆  -keep class * implements android.os.Parcelable {      public static final android.os.Parcelable$Creator *;  }    # 保留Serializable序列化的类不被混淆  -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();  }    # 对于带有回调函数的onXXEvent、**On*Listener的，不能被混淆  -keepclassmembers class * {      void *(**On*Event);      void *(**On*Listener);  }    # webView处理，项目中没有使用到webView忽略即可  -keepclassmembers class fqcn.of.javascript.interface.for.webview {      public *;  }  -keepclassmembers class * extends android.webkit.webViewClient {      public void *(android.webkit.WebView, java.lang.String, android.graphics.Bitmap);      public boolean *(android.webkit.WebView, java.lang.String);  }  -keepclassmembers class * extends android.webkit.webViewClient {      public void *(android.webkit.webView, jav.lang.String);  }    # 移除Log类打印各个等级日志的代码，打正式包的时候可以做为禁log使用，这里可以作为禁止log打印的功能使用  # 记得proguard-android.txt中一定不要加-dontoptimize才起作用  # 另外的一种实现方案是通过BuildConfig.DEBUG的变量来控制  #-assumenosideeffects class android.util.Log {  #    public static int v(...);  #    public static int i(...);  #    public static int w(...);  #    public static int d(...);  #    public static int e(...);  #}    #############################################  #  # 项目中特殊处理部分  #  #############################################    #-----------处理反射类---------------        #-----------处理js交互---------------        #-----------处理实体类---------------  # 在开发的时候我们可以将所有的实体类放在一个包内，这样我们写一次混淆就行了。  #-keep public class com.example.entity.** {  #    public void set*(***);  #    public *** get*();  #    public *** is*();  #}    #-----------处理第三方依赖库---------

最后一步，打签名包测试，如果有问题，仔细看下Log也许有的类不能混淆，那么你得加入到proguard-project.txt文件中。
