自動加固

我們的目標是全自動化，不需要做額外的配置,一鍵生成apk加固

自動下載 360 加固程序

完整的 config.gradle 配置：

ext {
    //簽名文件配置
    signing = [keyAlias     : 'xxxxx',
               keyPassword  : 'xxxxx',
               storeFile    : '../sign.keystore',
               storePassword: 'xxxxxx']

    //360加固配置
    jiagu = [name             : 'xxxxx',
             password         : 'xxxxx',
             zipPath          : "../jiagu/360jiagu.zip",
             unzipPath        : "../jiagu/360jiagubao/",
             jarPath          : '../jiagu/360jiagubao/jiagu/jiagu.jar',
             channelConfigPath: '../jiagu/Channel.txt',
             jiagubao_mac     : "http://down.360safe.com/360Jiagu/360jiagubao_mac.zip",
             jiagubao_windows : "http://down.360safe.com/360Jiagu/360jiagubao_windows_64.zip",
    ]

    android = [compileSdkVersion: 28,
               minSdkVersion    : 19,
               targetSdkVersion : 28]

    //版本號管理
    APP1_VERSION_NAME = "2.0.2"
    APP1_TEST_NUM = "0001"
    APP2_VERSION_NAME = "1.0.5"
    APP2_TEST_NUM = "0005"
}

新建一個 jiagu.gradle 文件：

import org.apache.tools.ant.taskdefs.condition.Os

def downloadUrl = Os.isFamily(Os.FAMILY_WINDOWS) ? rootProject.ext.jiagu["jiagubao_windows"] : rootProject.ext.jiagu["jiagubao_mac"]

def zipPath = rootProject.ext.jiagu["zipPath"]
def unzipPath = rootProject.ext.jiagu["unzipPath"]

task download360jiagu() {
    doFirst {
        //如果 Zip 文件不存在就進行下載
        File zipFile = file(zipPath)
        if (!zipFile.exists()) {
            if (!zipFile.parentFile.exists()) {
                zipFile.parentFile.mkdirs()
            }
            exec {
                executable = 'curl'
                args = ['-o', zipPath, downloadUrl]
            }
        }
    }
    doLast {
        //解壓 Zip 文件
        ant.unzip(src: zipPath, dest: unzipPath, encoding: "GBK")
        //將解壓后的文件開啟讀寫權(quán)限，防止執(zhí)行 Jar 文件沒有權(quán)限執(zhí)行
        exec {
            executable = 'chmod'
            args = ['-R', '777', unzipPath]
        }
    }
}

這個時候執(zhí)行 download360jiagu 會提示沒有該方法属百，原因是需要在app下的build.gradle添加該配置

apply from: '../jiagu.gradle'

這還不行，這個jiagu.gradle用到config.gradle变姨，在項目根目錄下的build.gradle添加即可

apply from: 'config.gradle'

根據(jù)多渠道文件進行加固族扰，這是只加固api渠道的

先添加兩個全局屬性

// 加固后所有apk的保存路徑
def API_OUTPUT_PATH = "jiagu/apk/api/"
// 加固前的api文件夾路徑
def API_APK_PATH = "${projectDir.absolutePath}/build/outputs/apk/api/release/"

兩個私有方法

/**
 * 檢查file
 */
private static void checkOutputDir(File apkOutputFile) {
    if (apkOutputFile.exists()) {
        File[] files = apkOutputFile.listFiles()
        if (files != null) {
            for (File file : files) {
                file.delete()
            }
        }
    } else {
        apkOutputFile.mkdirs()
    }
}

/**
 * @return 當(dāng)前時間,用于給加固后的包名
 */
static def getCurTime() {
    return new Date().format("yyyy-MM-dd-HH-mm-ss")
}

加固方法

/**

 * @param apkPath 要加固的文件路徑
 * @param outputPath 輸出路徑
 * @param automulpkg 是否自動生成多渠道包
 */
def jiaGu(String config, String apkPath, String outputPath, boolean automulpkg) {
    // 首次使用必須先登錄

        executable = 'java'
        args = ['-jar', rootProject.ext.jiagu["jarPath"], '-login', rootProject.ext.jiagu["name"], rootProject.ext.jiagu["password"]]

        jiaGuArgs = ['-jar', rootProject.ext.jiagu["jarPath"], '-jiagu',
                     apkPath,

        ]

        args = jiaGuArgs
    }
