android studio apk混淆

在Android Studio当中混淆APK实在是太简单了，借助SDK中自带的Proguard工具，只需要修改app module 下的build.gradle中的一行配置即可。可以看到，现在build.gradle中minifyEnabled的值是false，这里我们只需要把值改成true，编译出来的APK包就会是混淆过的了。如下所示：

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
            signingConfig signingConfigs.release
        }
        debug {
            signingConfig signingConfigs.debug
        }
    }

其中：

minifyEnabled用于设置是否启用混淆；

shrinkResources用于设置删除无效的Resources，shrinkResources依赖于minifyEnabled，必须一起使用；

proguardFiles用于选定混淆配置文件。注意这里是在release闭包内进行配置的，因此只有编译出正式版的APK才会进行混淆，Debug版的APK是不会混淆的。当然这也是非常合理的，因为Debug版的APK文件我们只会用来内部测试，不用担心被人破解。

proguard-android.txt混淆配置文件，该文件存放于android studio的sdk目录下androidsdk\tools\proguard，打开文件如下：

# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.

}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

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

-keepclassmembers class **.R$* {
    public static 
    
     ;
}

# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**

-keep class android.support.annotation.Keep

-keep @android.support.annotation.Keep class * {*;}

-keepclasseswithmembers class * {
    @android.support.annotation.Keep 
     
      ;
}

-keepclasseswithmembers class * {
    @android.support.annotation.Keep

android studio apk混淆

我就问你是不是感觉头很大，哈哈别着急下面还有解释。

这个就是默认的混淆配置文件了，我们来一起逐行阅读一下。

好了，这就是proguard-android.txt文件中所有默认的配置，而我们混淆代码也是按照这些配置的规则来进行混淆的。经过我上面的讲解之后，相信大家对这些配置的内容基本都能理解了。

回到Android Studio项目当中，APK虽然已经成功混淆了，但是混淆的规则都是按照proguard-android.txt中默认的规则来的，当然我们也可以修改proguard-android.txt中的规则，但是直接在proguard-android.txt中修改会对我们本机上所有项目的混淆规则都生效，那么有没有什么办法只针对当前项目的混淆规则做修改呢？当然是有办法的了，你会发现任何一个Android Studio项目在app模块目录下都有一个proguard-rules.txt（proguard-rules.pro）文件，这个文件就是用于让我们编写只适用于当前项目的混淆规则的。自定义混淆通用模板如下：
