1. 指定 混淆字典

在app的gralde里配置混淆字典

-obfuscationdictionary dict.txt#外部字典

-classobfuscationdictionary dict.txt #类字典

-packageobfuscationdictionary dict.txt #包字典

dict.txt 文件内容类似这样的：

zguqnx

mvdmuyh

wmws

jwomtp

nhmhn

zvlogo

pomcwh

bhdnzul

osxbj

gojb

ctvkrg

srmar

sgkarnqi

byghdn

tvebtxw

uxdhno

qmjac

pgxasjnc

ezfb

tuoe

pzdo

写了一个task

/*** 生成字典Task*/
task geneDictTask {doFirst{def dictPath = rootDir.getAbsolutePath()+'/app/dict.txt'def random = new Random()def lowercase = "abcdefghijklmnopqrstuvwxyz"def wordList = new HashSet()for (int i=0;i<10000;i++){def word = new StringBuilder()def wordLength = random.nextInt(5)+4for (int j=0;j

2. xmlClassGuard

xmlClassGuard {

/*

* 是否查找约束布局的constraint_referenced_ids属性的值，并添加到AabResGuard的白名单中，

* true的话，要求你在XmlClassGuard前依赖AabResGuard插件，默认false

*/

// findConstraintReferencedIds = true

//用于增量混淆的 mapping 文件

mappingFile = file("xml-class-mapping.txt")

//更改manifest文件的package属性，即包名

packageChange = ["com.DOTLESS.gala": "com.DOTLESS.gala"]

//移动目录

moveDir = ["com.DOTLESS.gala": "com.DOTLESS.gala"]

}

3. 批量修改文件名

ext {//需要批量重命名的Been路径renameBeenPath = "src/main/java/com/DOTLESS/gala/bean"//Been对象名字以什么字符串结尾, 默认Been, 例如设为Beax, 则所有Been都会以Beax结尾, 如GoodsBeax.ktbeenNameSuffix = "Bear"//Been名字的前缀, 例如KoGoodsBeenbeenPrefix = "Ko"//Been对象 Been的前面加的字符串 KoGoodsFishBeenbeenMidfix = "Fish"//特殊的Been比配
//    specialBeensMatcher = ["**/*Been.kt",  "**/*Been.java"]
}task renameBeenProcesser {doLast {FileTree beenTree = fileTree(renameBeenPath) {include '**/*.java'include '**/*.kt'
//            include specialBeensMatcher}def start = System.currentTimeMillis()println(">>>>>> renameBeenProcesser start")beenTree.each { File beenFile ->//println(beenFile.path + " Processing...")def sname = beenFile.namedef fileEx = sname.substring(sname.lastIndexOf("."))sname = sname.replace(fileEx, "")def tName = ""
//            if (sname.endsWith("Been")) {
//                tName = beenPrefix + sname.replace("Been", beenMidfix + beenNameSuffix)
//            } else if (sname.endsWith("Bean")) {
//                tName = beenPrefix + sname.replace("Bean", beenMidfix + beenNameSuffix)
//            } else {tName = beenPrefix + sname + beenMidfix + beenNameSuffix
//            }beenFile.renameTo(beenFile.parentFile.path + File.separator + tName + fileEx)//生成一个文件树,替换import后面的路径FileTree processTree = fileTree("src") {include '**/*.java'include '**/*.kt'include '**/layout/*.xml'}processTree.each { File f ->ImportBeenReplacer(f.path, sname, tName)}}def cost = (System.currentTimeMillis() - start) / 1000println(">>>>>> renameBeenProcesser end(cost:${cost}s)")}
}//替换有导入目标been的文件内容
def ImportBeenReplacer(String filePath, sourceBeenName, targetBeenName) {def readerString = ""def hasReplace = falsedef xml = filePath.endsWith(".xml")file(filePath).withReader('UTF-8') { reader ->reader.eachLine {String it ->if (it.find(sourceBeenName)) {if (xml) {//println("###$filePath: $sourceBeenName->$targetBeenName")it = it.replaceAll("(?]*)(?![a-zA-Z0-9]+)", targetBeenName)} else {it = it.replaceAll("(?\\?\\:\\(]*)(?![a-zA-Z0-9]+)", targetBeenName)}hasReplace = true}readerString <<= itreaderString << '\n'}}if (hasReplace) {if(readerString.toString().endsWith("\n")) readerString = readerString.subSequence(0, readerString.length() - 1)//替换文件//println(filePath + " has replace been.")file(filePath).withWriter('UTF-8') {writer ->writer.append(readerString)}}
}

4. androidJunkCode 添加垃圾代码

androidJunkCode {def config = {packageBase = "com.dotless.xthv"packageCount = 15activityCountPerPackage = 3excludeActivityJavaFile = falseotherCountPerPackage = 15methodCountPerClass = 10resPrefix = "xthv_"drawableCount = 10stringCount = 10}variantConfig {devDebug config  //和productFlavors里的名字一样，注意不能是大写，不然会报错devRelease configpublishDebug configpublishRelease config}
}
