max is 65536. 33 | You may try using --multi-dex option. 34 | ``` 35 | 36 | 这些错误状况都会显示下面这个数字：65,536。这个数字很重要，因为它代表的是单个 Dalvik Executable (DEX) 字节码文件内的代码可调用的引用总数。本节介绍如何通过启用被称为 *Dalvik 可执行文件分包*的应用配置来越过这一限制，使您的应用能够构建并读取 Dalvik 可执行文件分包 DEX 文件。 37 | 38 | ### 关于 64K 引用限制 39 | 40 | #### Android 5.0 之前版本的 Dalvik 可执行文件分包支持 41 | 42 | Android 5.0（API 级别 21）之前的平台版本使用 Dalvik 运行时来执行应用代码。默认情况下，Dalvik 限制应用的每个 APK 只能使用单个 `classes.dex` 字节码文件。要想绕过这一限制，您可以使用 [Dalvik 可执行文件分包支持库](https://developer.android.com/tools/support-library/features.html?hl=zh-cn#multidex)，它会成为您的应用主要 DEX 文件的一部分，然后管理对其他 DEX 文件及其所包含代码的访问。 43 | 44 | #### Android 5.0 及更高版本的 Dalvik 可执行文件分包支持 45 | 46 | Android 5.0（API 级别 21）及更高版本使用名为 ART 的运行时，后者原生支持从 APK 文件加载多个 DEX 文件。ART 在应用安装时执行预编译，扫描 `classesN.dex` 文件，并将它们编译成单个 `.oat` 文件，供 Android 设备执行。因此，如果您的 `minSdkVersion` 为 21 或更高值，则不需要 Dalvik 可执行文件分包支持库。 47 | 48 | ### 解决 64K 限制 49 | 50 | 1. 如果您的 `minSdkVersion` 设置为 21 或更高值，您只需在模块级 `build.gradle` 文件中将 `multiDexEnabled` 设置为 `true`，如此处所示： 51 | 52 | ```java 53 | android { 54 | defaultConfig { 55 | ... 56 | minSdkVersion 21 57 | targetSdkVersion 28 58 | multiDexEnabled true 59 | } 60 | ... 61 | } 62 | ``` 63 | 64 | 但是，如果您的 `minSdkVersion` 设置为 20 或更低值，则您必须按如下方式使用 [Dalvik 可执行文件分包支持库](https://developer.android.com/tools/support-library/features.html?hl=zh-cn#multidex)： 65 | 66 | - 修改模块级 `build.gradle` 文件以启用 Dalvik 可执行文件分包，并将 Dalvik 可执行文件分包库添加为依赖项，如此处所示 67 | 68 | ```java 69 | android { 70 | defaultConfig { 71 | ... 72 | minSdkVersion 15 73 | targetSdkVersion 28 74 | multiDexEnabled true 75 | } 76 | ... 77 | } 78 | 79 | dependencies { 80 | compile 'com.android.support:multidex:1.0.3' 81 | } 82 | ``` 83 | 84 | - 当前 Application extends MultiDexApplication {...} 或者 MultiDex.install(this); 85 | 86 | 2. 通过混淆 开启 ProGuard 移除未使用的代码，构建代码压缩。 87 | 88 | 3. 减少第三方库的直接依赖，尽可能下载源码，需要什么就用什么没必要依赖整个项目。 89 | 90 | ## Dex 加密与解密 91 | 92 | ![](https://user-gold-cdn.xitu.io/2019/6/2/16b18dbfe0ee1c3c?w=960&h=720&f=jpeg&s=22617) 93 | 94 | **流程:** 95 | 96 | 1. 拿到 APK 解压得到所有的 dex 文件。 97 | 2. 通过 Tools 来进行加密，并把加密后的 dex 和代理应用 class.dex 合并，然后重新签名，对齐，打包。 98 | 3. 当用户安装 APK 打开进入代理解密的 Application 时，反射得到 dexElements 并将解密后的 dex 替换 DexPathList 中的 dexElements . 99 | 100 | ### Dex 文件加载过程 101 | 102 | 既然要查 Dex 加载过程，那么得先知道从哪个源码 class 入手，既然不知道那么我们就先打印下 ClassLoader ; 103 | 104 | ![](https://user-gold-cdn.xitu.io/2019/6/2/16b18dc27dad72a8?w=761&h=438&f=jpeg&s=58192) 105 | 106 | 下面就以一个流程图来详细了解下 Dex 加载过程吧 107 | 108 | ![](https://user-gold-cdn.xitu.io/2019/6/2/16b18dc848c69036?w=1110&h=793&f=jpeg&s=35355) 109 | 110 | 最后我们得知在 **findClass(String name,List sup)** 遍历 **dexElements** 找到 Class 并交给 Android 加载。 111 | 112 | ### Dex 解密 113 | 114 | 现在我们知道 dex 加载流程了 , 那么我们怎么进行来对 dex 解密勒，刚刚我们得知需要遍历 dexElements 来找到 Class 那么我们是不是可以在遍历之前 ，初始化 dexElements 的时候。反射得到 dexElements 将我们解密后的 dex 交给 dexElements 。下面我们就通过代码来进行解密 dex 并替换 DexPathList 中的 dexElements; 115 | 116 | 1. 得到当前加密了的 APK 文件 并解压 117 | 118 | ```java 119 | //得到当前加密了的APK文件 120 | File apkFile=new File(getApplicationInfo().sourceDir); 121 | //把apk解压 app_name+"_"+app_version目录中的内容需要boot权限才能用 122 | File versionDir = getDir(app_name+"_"+app_version,MODE_PRIVATE); 123 | File appDir=new File(versionDir,"app"); 124 | File dexDir=new File(appDir,"dexDir"); 125 | ``` 126 | 127 | 2. 得到我们需要加载的 Dex 文件 128 | 129 | ```java 130 | //把apk解压到appDir 131 | Zip.unZip(apkFile,appDir); 132 | //获取目录下所有的文件 133 | File[] files=appDir.listFiles(); 134 | for (File file : files) { 135 | String name=file.getName(); 136 | if(name.endsWith(".dex") && !TextUtils.equals(name,"classes.dex")){ 137 | try{ 138 | AES.init(AES.DEFAULT_PWD); 139 | //读取文件内容 140 | byte[] bytes=Utils.getBytes(file); 141 | //解密 142 | byte[] decrypt=AES.decrypt(bytes); 143 | //写到指定的目录 144 | FileOutputStream fos=new FileOutputStream(file); 145 | fos.write(decrypt); 146 | fos.flush(); 147 | fos.close(); 148 | dexFiles.add(file); 149 | 150 | }catch (Exception e){ 151 | e.printStackTrace(); 152 | } 153 | } 154 | } 155 | ``` 156 | 157 | 3. 把解密后的 dex 加载到系统 158 | 159 | ```java 160 | private void loadDex(List dexFiles, File versionDir) throws Exception{ 161 | //1.获取pathlist 162 | Field pathListField = Utils.findField(getClassLoader(), "pathList"); 163 | Object pathList = pathListField.get(getClassLoader()); 164 | //2.获取数组dexElements 165 | Field dexElementsField=Utils.findField(pathList,"dexElements"); 166 | Object[] dexElements=(Object[])dexElementsField.get(pathList); 167 | //3.反射到初始化dexElements的方法 168 | Method makeDexElements=Utils.findMethod(pathList,"makePathElements",List.class,File.class,List.class); 169 | 170 | ArrayList suppressedExceptions = new ArrayList(); 171 | Object[] addElements=(Object[])makeDexElements.invoke(pathList,dexFiles,versionDir,suppressedExceptions); 172 | 173 | //合并数组 174 | Object[] newElements= (Object[])Array.newInstance(dexElements.getClass().getComponentType(),dexElements.length+addElements.length); 175 | System.arraycopy(dexElements,0,newElements,0,dexElements.length); 176 | System.arraycopy(addElements,0,newElements,dexElements.length,addElements.length); 177 | 178 | //替换 DexPathList 中的 element 数组 179 | dexElementsField.set(pathList,newElements); 180 | } 181 | ``` 182 | 183 | 解密已经完成了，下面来看看加密吧，这里为什么先说解密勒，因为 加密涉及到 签名，打包，对齐。所以留到最后讲。 184 | 185 | ### Dex 加密 186 | 187 | 1. 制作只包含解密代码的 dex 188 | 189 | ```java 190 | 1. sdk\build-tools 中执行下面命令 会得到包含 dex 的 jar 191 | dx --dex --output out.dex in.jar 192 | 2. 通过 exec 执行 193 | File aarFile=new File("proxy_core/build/outputs/aar/proxy_core-debug.aar"); 194 | File aarTemp=new File("proxy_tools/temp"); 195 | Zip.unZip(aarFile,aarTemp); 196 | File classesJar=new File(aarTemp,"classes.jar"); 197 | File classesDex=new File(aarTemp,"classes.dex"); 198 | String absolutePath = classesDex.getAbsolutePath(); 199 | String absolutePath1 = classesJar.getAbsolutePath(); 200 | //dx --dex --output out.dex in.jar 201 | //dx --dex --output //D:\Downloads\android_space\DexDEApplication\proxy_tools\temp\classes.dex //D:\Downloads\android_space\DexDEApplication\proxy_tools\temp\classes.jar 202 | Process process=Runtime.getRuntime().exec("cmd /c dx --dex --output "+classesDex.getAbsolutePath() 203 | +" "+classesJar.getAbsolutePath()); 204 | process.waitFor(); 205 | if(process.exitValue()!=0){ 206 | throw new RuntimeException("dex error"); 207 | } 208 | ``` 209 | 210 | 2. 加密 apk 中的 dex 文件 211 | 212 | ```java 213 | File apkFile=new File("app/build/outputs/apk/debug/app-debug.apk"); 214 | File apkTemp=new File("app/build/outputs/apk/debug/temp"); 215 | Zip.unZip(apkFile,apkTemp); 216 | //只要dex文件拿出来加密 217 | File[] dexFiles=apkTemp.listFiles(new FilenameFilter() { 218 | @Override 219 | public boolean accept(File file, String s) { 220 | return s.endsWith(".dex"); 221 | } 222 | }); 223 | //AES加密了 224 | AES.init(AES.DEFAULT_PWD); 225 | for (File dexFile : dexFiles) { 226 | byte[] bytes = Utils.getBytes(dexFile); 227 | byte[] encrypt = AES.encrypt(bytes); 228 | FileOutputStream fos=new FileOutputStream(new File(apkTemp, 229 | "secret-"+dexFile.getName())); 230 | fos.write(encrypt); 231 | fos.flush(); 232 | fos.close(); 233 | dexFile.delete(); 234 | } 235 | ``` 236 | 237 | 3. 把 dex 放入 apk 加压目录，重新压成 apk 文件 238 | 239 | ```java 240 | File apkTemp=new File("app/build/outputs/apk/debug/temp"); 241 | File aarTemp=new File("proxy_tools/temp"); 242 | File classesDex=new File(aarTemp,"classes.dex"); 243 | classesDex.renameTo(new File(apkTemp,"classes.dex")); 244 | File unSignedApk=new File("app/build/outputs/apk/debug/app-unsigned.apk"); 245 | Zip.zip(apkTemp,unSignedApk); 246 | ``` 247 | 248 | **现在可以看下加密后的文件，和未加密的文件** 249 | 250 | 未加密 apk: 251 | 252 | ![](https://user-gold-cdn.xitu.io/2019/6/2/16b18dce19cea368?w=1547&h=789&f=gif&s=307772) 253 | 254 | 加密后的 apk (现在只能看见代理 Application ) 255 | 256 | ![](https://user-gold-cdn.xitu.io/2019/6/2/16b18ddbef398ad5?w=1547&h=789&f=gif&s=367894) 257 | 258 | ### 打包 259 | 260 | #### [对齐](https://developer.android.google.cn/studio/command-line/zipalign.html) 261 | 262 | ```java 263 | //apk整理对齐工具 未压缩的数据开头均相对于文件开头部分执行特定的字节对齐，减少应用运行内存。 264 | zipalign -f 4 in.apk out.apk 265 | 266 | //比对 apk 是否对齐 267 | zipalign -c -v 4 output.apk 268 | 269 | //最后提示 Verification succesful 说明对齐成功了 270 | 236829 res/mipmap-xxxhdpi-v4/ic_launcher.png (OK - compressed) 271 | 245810 res/mipmap-xxxhdpi-v4/ic_launcher_round.png (OK - compressed) 272 | 260956 resources.arsc (OK - compressed) 273 | 317875 secret-classes.dex (OK - compressed) 274 | 2306140 secret-classes2.dex (OK - compressed) 275 | 2477544 secret-classes3.dex (OK - compressed) 276 | Verification succesful 277 | ``` 278 | 279 | #### 签名打包 apksigner 280 | 281 | ```java 282 | //sdk\build-tools\24.0.3 以上，apk签名工具 283 | apksigner sign --ks jks文件地址 --ks-key-alias 别名 --ks-pass pass:jsk密码 --key-pass pass:别名密码 --out out.apk in.apk 284 | ``` 285 | 286 | ## 总结 287 | 288 | 其实原理就是把主要代码通过命令 *dx* 生成 dex 文件，然后把加密后的 dex 合并在代理 class.dex 中。这样虽然还是能看见代理中的代码，但是主要代码已经没有暴露出来了，就已经实现了我们想要的效果。如果封装的好的话（JNI 中实现主要解密代码），基本上就哈也看不见了。ClassLoader 还是很重要的，热修复跟热加载都是这原理。学到这里 DEX 加解密已经学习完了，如果想看自己试一试可以参考我的代码 289 | 290 | [代码传送阵]() 291 | 292 | **如何学习本项目:** 293 | 294 | ![](https://devyk.oss-cn-qingdao.aliyuncs.com/blog/20200321010522.gif) 295 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 28 5 | defaultConfig { 6 | applicationId "com.yk.dexdeapplication" 7 | minSdkVersion 21 8 | targetSdkVersion 28 9 | versionCode 1 10 | versionName "1.0" 11 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 12 | } 13 | buildTypes { 14 | release { 15 | minifyEnabled true 16 | shrinkResources true 17 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 18 | } 19 | debug { 20 | minifyEnabled true 21 | shrinkResources true 22 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 23 | 'proguard-rules.pro' 24 | } 25 | } 26 | } 27 | 28 | dependencies { 29 | implementation fileTree(dir: 'libs', include: ['*.jar']) 30 | implementation 'com.android.support:appcompat-v7:28.0.0' 31 | implementation 'com.android.support.constraint:constraint-layout:1.1.3' 32 | testImplementation 'junit:junit:4.12' 33 | androidTestImplementation 'com.android.support.test:runner:1.0.2' 34 | androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' 35 | implementation project(':proxy_core') 36 | } 37 | -------------------------------------------------------------------------------- /app/debug/app.aab: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/yangkun19921001/DexEncryptionDecryption/43453801ee30ec1e0dfe6b1ac79b94fb7867f7bf/app/debug/app.aab -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # This is a configuration file for ProGuard. 2 | # http://proguard.sourceforge.net/index.html#manual/usage.html 3 | # 4 | # Starting with version 2.2 of the Android plugin for Gradle, this file is distributed together with 5 | # the plugin and unpacked at build-time.
