Android马甲包生成垃圾代码插件

Android垃圾代码生成插件

此插件用于做马甲包时，减小马甲包与主包的代码相似度，避免被OPPO、VIVO等应用市场识别为马甲包。

使用方法

根目录的build.gradle中：

buildscript {
    dependencies {
        classpath "cn.hx.plugin:android-junk-code:1.0.2"
    }
}

app目录的build.gradle模块中：

apply plugin: 'com.android.application'
apply plugin: 'android-junk-code'

android {
    //xxx
}

android.applicationVariants.all { variant ->
    switch (variant.name) {//变体名称，如果没有设置productFlavors就是buildType名称，如果有设置productFlavors就是flavor+buildType，例如（freeRelease、proRelease）
        case "release":
            androidJunkCode.configMap.put(variant.name, {
                packageBase = "cn.hx.plugin.ui"  //生成java类根包名
                packageCount = 30 //生成包数量
                activityCountPerPackage = 3 //每个包下生成Activity类数量
                otherCountPerPackage = 50  //每个包下生成其它类的数量
                methodCountPerClass = 20  //每个类下生成方法数量
                resPrefix = "junk_"  //生成的layout、drawable、string等资源名前缀
                drawableCount = 300  //生成drawable资源数量
                stringCount = 300  //生成string数量
            })
            break
    }
}
