android第三方库检测器源码

适用于 Android 应用程序的抗混淆、高精度和可靠的库检测器。LibPecker 采用签名匹配来给出给定库和应用程序之间的相似度分数。通过充分利用库内的内部类依赖关系，LibPecker 为每个类生成严格的签名。为了尽可能容忍库代码定制和消除，LibPecker在计算库相似度时引入了自适应类相似度阈值和加权类相似度分数。为了定量评估 LibPecker 的精确度和召回率，我们使用大量库和应用程序进行了第一个此类实验

快速开始

LibPecker 接受两个输入：Android 应用程序（.apk 文件）和库（.dex 文件）。LibPecker 返回一个相似度来描述可以在应用程序中找到多少库代码。

java -jar LibPecker.jar <apk_path> <lib_path>

要转换库文件（如.jar/.aar文件），可以在bin目录下使用dx命令。

#####Linux

./bin/dx --dex --output=<lib_dex> <lib_jar_path>

＃＃＃＃＃视窗

./bin/dx.sh --dex --output=<lib_dex> <lib_jar_path>

测试

我们还在测试目录中提供了一些测试用例。要测试这些情况，您可以运行此命令。

java -cp LibPecker.jar -Xmx4G cn.fudan.libpecker.main.TestDriver
